WAF bypass Tool is an open source tool to analyze the security of any WAF for False Positives and False Negatives using predefined and customizable payloads. Check your WAF before an attacker does. WAF Bypass Tool is developed by Nemesida WAF team with the participation of community.
It is forbidden to use for illegal and illegal purposes. Don't break the law. We are not responsible for possible risks associated with the use of this software.
The latest waf-bypass always available via the Docker Hub. It can be easily pulled via the following command:
# docker pull nemesida/waf-bypass
# docker run nemesida/waf-bypass --host='example.com'
# git clone https://github.com/nemesida-waf/waf_bypass.git /opt/waf-bypass/
# python3 -m pip install -r /opt/waf-bypass/requirements.txt
# python3 /opt/waf-bypass/main.py --host='example.com'
'--proxy'
(--proxy='http://proxy.example.com:3128'
) - option allows to specify where to connect to instead of the host.
'--header'
(--header 'Authorization: Basic YWRtaW46YWRtaW4=' --header 'X-TOKEN: ABCDEF'
) - option allows to specify the HTTP header to send with all requests (e.g. for authentication). Multiple use is allowed.
'--user-agent'
(--user-agent 'MyUserAgent 1/1'
) - option allows to specify the HTTP User-Agent to send with all requests, except when the User-Agent is set by the payload ("USER-AGENT"
).
'--block-code'
(--block-code='403' --block-code='222'
) - option allows you to specify the HTTP status code to expect when the WAF is blocked. (default is 403
). Multiple use is allowed.
'--threads'
(--threads=15
) - option allows to specify the number of parallel scan threads (default is 10
).
'--timeout'
(--timeout=10
) - option allows to specify a request processing timeout in sec. (default is 30
).
'--json-format'
- an option that allows you to display the result of the work in JSON format (useful for integrating the tool with security platforms).
'--details'
- display the False Positive and False Negative payloads. Not available in JSON
format.
'--exclude-dir'
- exclude the payload's directory (--exclude-dir='SQLi' --exclude-dir='XSS'
). Multiple use is allowed.
Depending on the purpose, payloads are located in the appropriate folders:
When compiling a payload, the following zones, method and options are used:
Base64
, HTML-ENTITY
, UTF-16
) in addition to the encoding for the payload. Multiple values are indicated with a space (e.g. Base64 UTF-16
). Applicable only to for ARGS
, BODY
, COOKIE
and HEADER
zone. Not applicable to payloads in API and MFD directories. Not compatible with option JSON
.Except for some cases described below, the zones are independent of each other and are tested separately (those if 2 zones are specified - the script will send 2 requests - alternately checking one and the second zone).
For the zones you can use %RND%
suffix, which allows you to generate an arbitrary string of 6 letters and numbers. (e.g.: param%RND=my_payload
or param=%RND%
OR A%RND%B
)
You can create your own payloads, to do this, create your own folder on the '/payload/' folder, or place the payload in an existing one (e.g.: '/payload/XSS'). Allowed data format is JSON.
API testing payloads located in this directory are automatically appended with a header 'Content-Type: application/json'
.
For MFD (multipart/form-data) payloads located in this directory, you must specify the BODY
(required) and BOUNDARY
(optional). If BOUNDARY
is not set, it will be generated automatically (in this case, only the payload must be specified for the BODY, without additional data ('... Content-Disposition: form-data; ...'
).
If a BOUNDARY
is specified, then the content of the BODY
must be formatted in accordance with the RFC, but this allows for multiple payloads in BODY
a separated by BOUNDARY
.
Other zones are allowed in this directory (e.g.: URL
, ARGS
etc.). Regardless of the zone, header 'Content-Type: multipart/form-data; boundary=...'
will be added to all requests.
This is a Proof Of Concept application that demostrates how AI can be used to generate accurate results for vulnerability analysis and also allows further utilization of the already super useful ChatGPT.

Microsoft on Tuesday released updates to quash at least 74 security bugs in its Windows operating systems and software. Two of those flaws are already being actively attacked, including an especially severe weakness in Microsoft Outlook that can be exploited without any user interaction.
The Outlook vulnerability (CVE-2023-23397) affects all versions of Microsoft Outlook from 2013 to the newest. Microsoft said it has seen evidence that attackers are exploiting this flaw, which can be done without any user interaction by sending a booby-trapped email that triggers automatically when retrieved by the email server — before the email is even viewed in the Preview Pane.
While CVE-2023-23397 is labeled as an “Elevation of Privilege” vulnerability, that label doesn’t accurately reflect its severity, said Kevin Breen, director of cyber threat research at Immersive Labs.
Known as an NTLM relay attack, it allows an attacker to get someone’s NTLM hash [Windows account password] and use it in an attack commonly referred to as “Pass The Hash.”
“The vulnerability effectively lets the attacker authenticate as a trusted individual without having to know the person’s password,” Breen said. “This is on par with an attacker having a valid password with access to an organization’s systems.”
Security firm Rapid7 points out that this bug affects self-hosted versions of Outlook like Microsoft 365 Apps for Enterprise, but Microsoft-hosted online services like Microsoft 365 are not vulnerable.
The other zero-day flaw being actively exploited in the wild — CVE-2023-24880 — is a “Security Feature Bypass” in Windows SmartScreen, part of Microsoft’s slate of endpoint protection tools.
Patch management vendor Action1 notes that the exploit for this bug is low in complexity and requires no special privileges. But it does require some user interaction, and can’t be used to gain access to private information or privileges. However, the flaw can allow other malicious code to run without being detected by SmartScreen reputation checks.
Dustin Childs, head of threat awareness at Trend Micro’s Zero Day Initiative, said CVE-2023-24880 allows attackers to create files that would bypass Mark of the Web (MOTW) defenses.
“Protective measures like SmartScreen and Protected View in Microsoft Office rely on MOTW, so bypassing these makes it easier for threat actors to spread malware via crafted documents and other infected files that would otherwise be stopped by SmartScreen,” Childs said.
Seven other vulnerabilities Microsoft patched this week earned its most-dire “critical” severity label, meaning the updates address security holes that could be exploited to give the attacker full, remote control over a Windows host with little or no interaction from the user.
Also this week, Adobe released eight patches addressing a whopping 105 security holes across a variety of products, including Adobe Photoshop, Cold Fusion, Experience Manager, Dimension, Commerce, Magento, Substance 3D Stager, Cloud Desktop Application, and Illustrator.
For a more granular rundown on the updates released today, see the SANS Internet Storm Center roundup. If today’s updates cause any stability or usability issues in Windows, AskWoody.com will likely have the lowdown on that.
Please consider backing up your data and/or imaging your system before applying any updates. And feel free to sound off in the comments if you experience any problems as a result of these patches.

An automatic unpacker and logger for DotNet Framework targeting files! This tool has been unveiled at Black Hat USA 2022.
The automatic detection and classification of any given file in a reliable manner is often considered the holy grail of malware analysis. The trials and tribulations to get there are plenty, which is why the creation of such a system is held in high regard. When it comes to DotNet targeting binaries, our new open-source tool DotDumper aims to assist in several of the crucial steps along the way: logging (in-memory) activity, dumping interesting memory segments, and extracting characteristics from the given sample.
In brief, manual unpacking is a tedious process which consumes a disproportional amount of time for analysts. Obfuscated binaries further increase the time an analyst must spend to unpack a given file. When scaling this, organizations need numerous analysts who dissect malware daily, likely in combination with a scalable sandbox. The lost valuable time could be used to dig into interesting campaigns or samples to uncover new threats, rather than the mundane generic malware that is widely spread. Afterall, analysts look for the few needles in the haystack.
So, what difference does DotDumper make? Running a DotNet based malware sample via DotDumper provides log files of crucial, contextualizing, and common function calls in three formats (human readable plaintext, JSON, and XML), as well as copies from useful in-memory segments. As such, an analyst can skim through the function call log. Additionally, the dumped files can be scanned to classify them, providing additional insight into the malware sample and the data it contains. This cuts down on time vital to the triage and incident response processes, and frees up SOC analyst and researcher time for more sophisticated analysis needs.
To log and dump the contextualizing function calls and their results, DotDumper uses a mixture of reflection and managed hooks, all written in pure C#. Below, key features will be highlighted and elaborated upon, in combination with excerpts of DotDumper’s results of a packed AgentTesla stealer sample, the hashes of which are below.
Hash type | Hash value |
---|---|
SHA-256 | b7512e6b8e9517024afdecc9e97121319e7dad2539eb21a79428257401e5558d |
SHA-1 | c10e48ee1f802f730f41f3d11ae9d7bcc649080c |
MD-5 | 23541daadb154f1f59119952e7232d6b |
DotDumper is accessible through a command-line interface, with a variety of arguments. The image below shows the help menu. Note that not all arguments will be discussed, but rather the most used ones.
The minimal requirement to run a given sample, is to provide the “-file” argument, along with a file name or file path. If a full path is given, it is used. If a file name is given, the current working directory is checked, as well as the folder of DotDumper’s executable location.
Unless a directory name is provided, the “-log” folder name is set equal to the file name of the sample without the extension (if any). The folder is located in the same folder as DotDumper resides in, which is where the logs and dumped files will be saved in.
In the case of a library, or an alternative entry point into a binary, one must override the entry point using “-overrideEntry true”. Additionally, one has to provide the fully qualified class, which includes the name space using “-fqcn My.NameSpace.MyClass”. This tells DotDumper which class to select, which is where the provided function name (using “-functionName MyFunction”) is retrieved.
If the selected function requires arguments, one has to provide the number of arguments using “-argc” and the number of required arguments. The argument types and values are to be provided as “string|myValue int|9”. Note that when spaces are used in the values, the argument on the command-line interface needs to be encapsulated between quotes to ensure it is passed as a single argument.
Other less frequently used options such as “-raceTime” or “-deprecated” are safe in their default settings but might require tweaking in the future due to changes in the DotNet Framework. They are currently exposed in the command-line interface to easily allow changes, if need be, even if one is using an older version of DotDumper when the time comes.
Logging and dumping are the two core features of DotDumper. To minimize the amount of time the analysis takes, the logging should provide context to the analyst. This is done by providing the analyst with the following information for each logged function call:
Note that for each dumped file, the file name is equal to the file’s SHA-256 hash.
To clarify the above, an excerpt of a log is given below. The excerpt shows the details for the aforementioned AgentTesla sample, where it loads the second stage using DotNet’s Assembly.Load function.
First, the local system time is given, together with the original function’s return type, name, and argument(s). Second, the stack trace is given, where it shows that the sample’s main function leads to a constructor, initialises the components, and calls two custom functions. The Assembly.Load function was called from within “NavigationLib.TaskEightBestOil.GGGGGGGGGGGGGGGGGGGG(String str)”. This provides context for the analyst to find the code around this call if it is of interest.
Then, information regarding the assembly call order is given. The more stages are loaded, the more complex it becomes to see via which stages the call came to be. One normally expects one stage to load the next, but in some cases later stages utilize previous stages in a non-linear order. Additionally, information regarding the originating assembly is given to further enrich the data for the analyst.
Next, the parent hash is given. The parent of a stage is the previous stage, which in this example is not yet present. The newly loaded stage will have this stage as its parent. This allows the analyst to correlate events more easily.
Finally, the function’s return type and value are stored, along with the type, name, and value of each argument that is passed to the hooked function. If any variable is larger than 100 bytes in size, it is stored on the disk instead. A reference is then inserted in the log to reference the file, rather than showing the value. The threshold has been set to avoid hiccups in the printing of the log, as some arrays are thousands of indices in size.
Per Microsoft’s documentation, reflection is best summarized as “[…] provides objects that encapsulate assemblies, modules, and types”. In short, this allows the dynamic creation and invocation of DotNet classes and functions from the malware sample. DotDumper contains a reflective loader which allows an analyst to load and analyze both executables and libraries, as long as they are DotNet Framework based.
To utilize the loader, one has to opt to overwrite the entry point in the command-line interface, specify the class (including the namespace it resides in) and function name within a given file. Optionally, one can provide arguments to the specified function, for all native types and arrays thereof. Examples of native types are int, string, char, and arrays such as int[], string[], and char[]. All the arguments are to be provided via the command-line interface, where both the type and the value are to be specified.
Not overriding the entry point results in the default entry point being used. By default, an empty string array is passed towards the sample’s main function, as if the sample is executed without arguments. Additionally, reflection is often used by loaders to invoke a given function in a given class in the next stage. Sometimes, arguments are passed along as well, which are used later to decrypt a resource. In the aforementioned AgentTesla sample, this exact scenario plays out. DotDumper’s invoke related hooks log these occurrences, as can be seen below.
The function name in the first line is not an internal function of the DotNet Framework, but rather a call to a specific function in the second stage. The types and names of the three arguments are listed in the function signature. Their values can be found in the function argument information section. This would allow an analyst to load the second stage in a custom loader with the given values for the arguments, or even do this using DotDumper by loading the previously dumped stage and providing the arguments.
Before going into managed hooks, one needs to understand how hooks work. There are two main variables to consider here: the target function and a controlled function which is referred to as the hook. Simply put, the memory at the target function (i.e. Assembly.Load) is altered to instead to jump to the hook. As such, the program’s execution flow is diverted. The hook can then perform arbitrary actions, optionally call the original function, after which it returns the execution to the caller together with a return value if need be. The diagram below illustrates this process.
Knowing what hooks are is essential to understand what managed hooks are. Managed code is executed in a virtual and managed environment, such as the DotNet runtime or Java’s virtual machine. Obtaining the memory address where the managed function resides differs from an unmanaged language such as C. Once the correct memory addresses for both functions have been obtained, the hook can be set by directly accessing memory using unsafe C#, along with DotNet’s interoperability service to call native Windows API functionality.
Since DotDumper is written in pure C# without any external dependencies, one can easily extend the framework using Visual Studio. The code is documented in this blog, on GitHub, and in classes, in functions, and in-line in the source code. This, in combination with the clear naming scheme, allows anyone to modify the tool as they see fit, minimizing the time and effort that one needs to spend to understand the tool. Instead, it allows developers and analysts alike to focus their efforts on the tool’s improvement.
With the goal and features of DotDumper clear, it might seem as if there’s overlap with known publicly available tools such as ILSpy, dnSpyEx, de4dot, or pe-sieve. Note that there is no intention to proclaim one tool is better than another, but rather how the tools differ.
DotDumper’s goal is to log and dump crucial, contextualizing, and common function calls from DotNet targeting samples. ILSpy is a DotNet disassembler and decompiler, but does not allow the execution of the file. dnSpyEx (and its predecessor dnSpy) utilise ILSpy as the disassembler and decompiler component, while adding a debugger. This allows one to manually inspect and manipulate memory. de4dot is solely used to deobfuscate DotNet binaries, improving the code’s readability for human eyes. The last tool in this comparison, pe-sieve, is meant to detect and dump malware from running processes, disregarding the used programming language. The table below provides a graphical overview of the above-mentioned tools.
DotDumper is under constant review and development, all of which is focused on two main areas of interest: bug fixing and the addition of new features. During the development, the code was tested, but due to injection of hooks into the DotNet Framework’s functions which can be subject to change, it’s very well possible that there are bugs in the code. Anyone who encounters a bug is urged to open an issue on the GitHub repository, which will then be looked at. The suggestion of new features is also possible via the GitHub repository. For those with a GitHub account, or for those who rather not publicly interact, feel free to send me a private message on my Twitter.
Needless to say, if you've used DotDumper during an analysis, or used it in a creative way, feel free to reach out in public or in private! There’s nothing like hearing about the usage of a home-made tool!
There is more in store for DotDumper, and an update will be sent out to the community once it is available!

Microsoft has released its final monthly batch of security updates for 2022, fixing more than four dozen security holes in its various Windows operating systems and related software. The most pressing patches include a zero-day in a Windows feature that tries to flag malicious files from the Web, a critical bug in PowerShell, and a dangerous flaw in Windows 11 systems that was detailed publicly prior to this week’s Patch Tuesday.
The security updates include patches for Azure, Microsoft Edge, Office, SharePoint Server, SysInternals, and the .NET framework. Six of the update bundles earned Microsoft’s most dire “critical” rating, meaning they fix vulnerabilities that malware or malcontents can use to remotely commandeer an unpatched Windows system — with little to no interaction on the part of the user.
The bug already seeing exploitation is CVE-2022-44698, which allows attackers to bypass the Windows SmartScreen security feature. The vulnerability allows attackers to craft documents that won’t get tagged with Microsoft’s “Mark of the Web,” despite being downloaded from untrusted sites.
“This means no Protected View for Microsoft Office documents, making it easier to get users to do sketchy things like execute malicious macros, said Greg Wiseman, product manager at security firm Rapid7. This is the second Mark of the Web flaw Microsoft has patched in as many months; both were first publicly detailed over the past two months on Twitter by security researcher Will Dormann.
Publicly disclosed (but not actively exploited for now) is CVE-2022-44710, which is an elevation of privilege flaw in the DirectX graphics component of Windows 11.
Another notable critical bug is CVE-2022-41076, a remote code execution flaw in PowerShell — a key component of Windows that makes it easier to automate system tasks and configurations.
Kevin Breen at Immersive Labs said while Microsoft doesn’t share much detail about CVE-2022-41076 apart from the designation ‘Exploitation More Likely,’ they also note that successful exploitation requires an attacker to take additional actions to prepare the target environment.
“What actions are required is not clear; however, we do know that exploitation requires an authenticated user level of access,” Breen said. “This combination suggests that the exploit requires a social engineering element, and would likely be seen in initial infections using attacks like MalDocs or LNK files.”
Speaking of malicious documents, Trend Micro’s Zero Day Initiative highlights CVE-2022-44713, a spoofing vulnerability in Outlook for Mac.
“We don’t often highlight spoofing bugs, but anytime you’re dealing with a spoofing bug in an e-mail client, you should take notice,” ZDI’s Dustin Childs wrote. “This vulnerability could allow an attacker to appear as a trusted user when they should not be. Now combine this with the SmartScreen Mark of the Web bypass and it’s not hard to come up with a scenario where you receive an e-mail that appears to be from your boss with an attachment entitled “Executive_Compensation.xlsx”. There aren’t many who wouldn’t open that file in that scenario.”
Microsoft also released guidance on reports that certain software drivers certified by Microsoft’s Windows Hardware Developer Program were being used maliciously in post-exploitation activity.
Three different companies reported evidence that malicious hackers were using these signed malicious driver files to lay the groundwork for ransomware deployment inside victim organizations. One of those companies, Sophos, published a blog post Tuesday detailing how the activity was tied to the Russian ransomware group Cuba, which has extorted an estimated $60 million from victims since 2019.
Of course, not all scary and pressing security threats are Microsoft-based. Also on Tuesday, Apple released a bevy of security updates to iOS, iPadOS, macOS, tvOS and Safari, including a patch for a newly discovered zero-day vulnerability that could lead to remote code execution.
Anyone responsible for maintaining Fortinet or Citrix remote access products probably needs to update, as both are dealing with active attacks on just-patched flaws.
For a closer look at the patches released by Microsoft today (indexed by severity and other metrics) check out the always-useful Patch Tuesday roundup from the SANS Internet Storm Center. And it’s not a bad idea to hold off updating for a few days until Microsoft works out any kinks in the updates: AskWoody.com usually has the lowdown on any patches that may be causing problems for Windows users.

A 25-year-old Finnish man has been charged with extorting a once popular and now-bankrupt online psychotherapy company and its patients. Finnish authorities rarely name suspects in an investigation, but they were willing to make an exception for Julius “Zeekill” Kivimaki, a notorious hacker who — at the tender age of 17 — had been convicted of more than 50,000 cybercrimes, including data breaches, payment fraud, operating botnets, and calling in bomb threats.
In late October 2022, Kivimaki was charged (and arrested in absentia, according to the Finns) with attempting to extort money from the Vastaamo Psychotherapy Center. On October 21, 2020, Vastaamo became the target of blackmail when a tormentor identified as “ransom_man” demanded payment of 40 bitcoins (~450,000 euros at the time) in return for a promise not to publish highly sensitive therapy session notes Vastaamo had exposed online.
In a series of posts over the ensuing days on a Finnish-language dark net discussion board, ransom_man said Vastaamo appeared unwilling to negotiate a payment, and that he would start publishing 100 patient profiles every 24 hours “to provide further incentive for the company to continue communicating with us.”
“We’re not asking for much, approximately 450,000 euros which is less than 10 euros per patient and only a small fraction of the around 20 million yearly revenues of this company,” ransom_man wrote.
When Vastaamo declined to pay, ransom_man shifted to extorting individual patients. According to Finnish police, some 22,000 victims reported extortion attempts targeting them personally, targeted emails that threatened to publish their therapy notes online unless paid a 500 euro ransom.
The extortion message targeted Vastaamo patients.
On Oct. 23, 2020, ransom_man uploaded to the dark web a large compressed file that included all of the stolen Vastaamo patient records. But investigators found the file also contained an entire copy of ransom_man’s home folder, a likely mistake that exposed a number of clues that they say point to Kivimaki.
Ransom_man quickly deleted the large file (accompanied by a “whoops” notation), but not before it had been downloaded a number of times. The entire archive has since been made into a searchable website on the Dark Web.
Among those who grabbed a copy of the database was Antti Kurittu, a team lead at Nixu Corporation and a former criminal investigator. In 2013, Kurittu worked on investigation involving Kivimaki’s use of the Zbot botnet, among other activities Kivimaki engaged in as a member of the hacker group Hack the Planet.
“It was a huge opsec [operational security] fail, because they had a lot of stuff in there — including the user’s private SSH folder, and a lot of known hosts that we could take a very good look at,” Kurittu told KrebsOnSecurity, declining to discuss specifics of the evidence investigators seized. “There were also other projects and databases.”
Kurittu said he and others he and others who were familiar with illegal activities attributed to Kivimäki couldn’t shake suspicion that the infamous cybercriminal was also behind the Vastaamo extortion.
“I couldn’t find anything that would link that data directly to one individual, but there were enough indicators in there that put the name in my head and I couldn’t shake it,” Kurittu said. “When they named him as the prime suspect I was not surprised.”
A handful of individually extorted victims paid a ransom, but when news broke that the entire Vastaamo database had been leaked online, the extortion threats no longer held their sting. However, someone would soon set up a site on the dark web where anyone could search this sensitive data.
Kivimaki stopped using his middle name Julius in favor of his given first name Aleksanteri when he moved abroad several years ago. A Twitter account by that name was verified by Kivimaki’s attorney as his, and through that account he denied being involved in the Vastaamo extortion.
“I believe [the Finnish authorities] brought this to the public in order to influence the decision-making of my old case from my teenage years, which was just processed in the Court of Appeal, both cases are investigated by the same persons,” Kivimaki tweeted on Oct. 28.
Kivimaki is appealing a 2020 district court decision sentencing him to “one year of conditional imprisonment for two counts of fraud committed as a young person, and one of gross fraud, interference with telecommunications as a young person, aggravated data breach as a young person and incitement to fraud as a young person,” according to the Finnish tabloid Ilta-Sanomat.
“Now in the Court of Appeal, the prosecutor is demanding a harsher punishment for the man, i.e. unconditional imprisonment,” reads the Ilta-Sanomat story. “The prosecutor notes in his complaint that the young man has been committing cybercrimes from Espoo since he was 15 years old, and the actions have had to be painstakingly investigated through international legal aid.”
As described in this Wired story last year, Vastaamo filled an urgent demand for psychological counseling, and it won accolades from Finnish health authorities and others for its services.
“Vastaamo was a private company, but it seemed to operate in the same spirit of tech-enabled ease and accessibility: You booked a therapist with a few clicks, wait times were tolerable, and Finland’s Social Insurance Institution reimbursed a big chunk of the session fee (provided you had a diagnosed mental disorder),” William Ralston wrote for Wired. “The company was run by Ville Tapio, a 39-year-old coder and entrepreneur with sharp eyebrows, slicked-back brown hair, and a heavy jawline. He’d cofounded the company with his parents. They pitched Vastaamo as a humble family-run enterprise committed to improving the mental health of all Finns.”
But for all the good it brought, the healthcare records management system that Vastaamo used relied on little more than a MySQL database that was left dangerously exposed to the web for 16 months, guarded by nothing more than an administrator account with a blank password.
The Finnish daily Iltalehti said Tapio was relieved of his duties as CEO of Vastaamo in October 2020, and that in September, prosecutors brought charges against Tapio for a data protection offense in connection with Vastaamo’s information leak.
“According to Vastaamo, the data breach in Vastaamo’s customer databases took place in November 2018,” Iltalehti reported last month. “According to Vastaamo, Tapio concealed information about the data breach for more than a year and a half.”
Another shellcode injection technique using C++ that attempts to bypass Windows Defender using XOR encryption sorcery and UUID strings madness :).
Firstly, generate a payload in binary format( using either CobaltStrike
or msfvenom
) for instance, in msfvenom
, you can do it like so( the payload I'm using is for illustration purposes, you can use whatever payload you want ):
msfvenom -p windows/messagebox -f raw -o shellcode.bin
Then convert the shellcode( in binary/raw format ) into a UUID
string format using the Python3 script, bin_to_uuid.py
:
./bin_to_uuid.py -p shellcode.bin > uuid.txt
xor
encrypt the UUID
strings in the uuid.txt
using the Python3 script, xor_encryptor.py
.
./xor_encryptor.py uuid.txt > xor_crypted_out.txt
Copy the C-style
array in the file, xor_crypted_out.txt
, and paste it in the C++ file as an array of unsigned char
i.e. unsigned char payload[]{your_output_from_xor_crypted_out.txt}
This shellcode injection technique comprises the following subsequent steps:
VirtualAlloc
xor
decrypts the payload using the xor
key valueUuidFromStringA
to convert UUID
strings into their binary representation and store them in the previously allocated memory. This is used to avoid the usage of suspicious APIs like WriteProcessMemory
or memcpy
.EnumChildWindows
to execute the payload previously loaded into memory( in step 1 )memcpy
or WriteProcessMemory
which are known to raise alarms to AVs/EDRs, this program uses the Windows API function called UuidFromStringA
which can be used to decode data as well as write it to memory( Isn't that great folks? And please don't say "NO!" :) ).xor
key(row 86) to what you wish. This can be done in the ./xor_encryptor.py
python3 script by changing the KEY
variable.executable filename
value(row 90) to your filename.mingw
was used but you can use whichever compiler you prefer. :)make
The binary was scanned using antiscan.me on 01/08/2022.

Microsoft today released updates to fix at least 85 security holes in its Windows operating systems and related software, including a new zero-day vulnerability in all supported versions of Windows that is being actively exploited. However, noticeably absent from this month’s Patch Tuesday are any updates to address a pair of zero-day flaws being exploited this past month in Microsoft Exchange Server.
The new zero-day flaw– CVE-2022-41033 — is an “elevation of privilege” bug in the Windows COM+ event service, which provides system notifications when users logon or logoff. Microsoft says the flaw is being actively exploited, and that it was reported by an anonymous individual.
“Despite its relatively low score in comparison to other vulnerabilities patched today, this one should be at the top of everyone’s list to quickly patch,” said Kevin Breen, director of cyber threat research at Immersive Labs. “This specific vulnerability is a local privilege escalation, which means that an attacker would already need to have code execution on a host to use this exploit. Privilege escalation vulnerabilities are a common occurrence in almost every security compromise. Attackers will seek to gain SYSTEM or domain-level access in order to disable security tools, grab credentials with tools like Mimkatz and move laterally across the network.
Indeed, Satnam Narang, senior staff research engineer at Tenable, notes that almost half of the security flaws Microsoft patched this week are elevation of privilege bugs.
Some privilege escalation bugs can be particularly scary. One example is CVE-2022-37968, which affects organizations running Kubernetes clusters on Azure and earned a CVSS score of 10.0 — the most severe score possible.
Microsoft says that to exploit this vulnerability an attacker would need to know the randomly generated DNS endpoint for an Azure Arc-enabled Kubernetes cluster. But that may not be such a tall order, says Breen, who notes that a number of free and commercial DNS discovery services now make it easy to find this information on potential targets.
Late last month, Microsoft acknowledged that attackers were exploiting two previously unknown vulnerabilities in Exchange Server. Paired together, the two flaws are known as “ProxyNotShell” and they can be chained to allow remote code execution on Exchange Server systems.
Microsoft said it was expediting work on official patches for the Exchange bugs, and it urged affected customers to enable certain settings to mitigate the threat from the attacks. However, those mitigation steps were soon shown to be ineffective, and Microsoft has been adjusting them on a daily basis nearly each day since then.
The lack of Exchange patches leaves a lot of Microsoft customers exposed. Security firm Rapid7 said that as of early September 2022 the company observed more than 190,000 potentially vulnerable instances of Exchange Server exposed to the Internet.
“While Microsoft confirmed the zero-days and issued guidance faster than they have in the past, there are still no patches nearly two weeks out from initial disclosure,” said Caitlin Condon, senior manager of vulnerability research at Rapid7. “Despite high hopes that today’s Patch Tuesday release would contain fixes for the vulnerabilities, Exchange Server is conspicuously missing from the initial list of October 2022 security updates. Microsoft’s recommended rule for blocking known attack patterns has been bypassed multiple times, emphasizing the necessity of a true fix.”
Adobe also released security updates to fix 29 vulnerabilities across a variety of products, including Acrobat and Reader, ColdFusion, Commerce and Magento. Adobe said it is not aware of active attacks against any of these flaws.
For a closer look at the patches released by Microsoft today and indexed by severity and other metrics, check out the always-useful Patch Tuesday roundup from the SANS Internet Storm Center. And it’s not a bad idea to hold off updating for a few days until Microsoft works out any kinks in the updates: AskWoody.com usually has the lowdown on any patches that may be causing problems for Windows users.
As always, please consider backing up your system or at least your important documents and data before applying system updates. And if you run into any problems with these updates, please drop a note about it here in the comments.
When U.S. consumers have their online bank accounts hijacked and plundered by hackers, U.S. financial institutions are legally obligated to reverse any unauthorized transactions as long as the victim reports the fraud in a timely manner. But new data released this week suggests that for some of the nation’s largest banks, reimbursing account takeover victims has become more the exception than the rule.
The findings came in a report released by Sen. Elizabeth Warren (D-Mass.), who in April 2022 opened an investigation into fraud tied to Zelle, the “peer-to-peer” digital payment service used by many financial institutions that allows customers to quickly send cash to friends and family.
Zelle is run by Early Warning Services LLC (EWS), a private financial services company which is jointly owned by Bank of America, Capital One, JPMorgan Chase, PNC Bank, Truist, U.S. Bank, and Wells Fargo. Zelle is enabled by default for customers at over 1,000 different financial institutions, even if a great many customers still don’t know it’s there.
Sen. Warren said several of the EWS owner banks — including Capital One, JPMorgan and Wells Fargo — failed to provide all of the requested data. But Warren did get the requested information from PNC, Truist and U.S. Bank.
“Overall, the three banks that provided complete data sets reported 35,848 cases of scams, involving over $25.9 million of payments in 2021 and the first half of 2022,” the report summarized. “In the vast majority of these cases, the banks did not repay the customers that reported being scammed. Overall these three banks reported repaying customers in only 3,473 cases (representing nearly 10% of scam claims) and repaid only $2.9 million.”
Importantly, the report distinguishes between cases that involve straight up bank account takeovers and unauthorized transfers (fraud), and those losses that stem from “fraudulently induced payments,” where the victim is tricked into authorizing the transfer of funds to scammers (scams).
A common example of the latter is the Zelle Fraud Scam, which uses an ever-shifting set of come-ons to trick people into transferring money to fraudsters. The Zelle Fraud Scam often employs text messages and phone calls spoofed to look like they came from your bank, and the scam usually relates to fooling the customer into thinking they’re sending money to themselves when they’re really sending it to the crooks.
Here’s the rub: When a customer issues a payment order to their bank, the bank is obligated to honor that order so long as it passes a two-stage test. The first question asks, Did the request actually come from an authorized owner or signer on the account? In the case of Zelle scams, the answer is yes.
Trace Fooshee, a strategic advisor in the anti money laundering practice at Aite-Novarica, said the second stage requires banks to give the customer’s transfer order a kind of “sniff test” using “commercially reasonable” fraud controls that generally are not designed to detect patterns involving social engineering.
Fooshee said the legal phrase “commercially reasonable” is the primary reason why no bank has much — if anything — in the way of controlling for scam detection.
“In order for them to deploy something that would detect a good chunk of fraud on something so hard to detect they would generate egregiously high rates of false positives which would also make consumers (and, then, regulators) very unhappy,” Fooshee said. “This would tank the business case for the service as a whole rendering it something that the bank can claim to NOT be commercially reasonable.”
Sen. Warren’s report makes clear that banks generally do not pay consumers back if they are fraudulently induced into making Zelle payments.
“In simple terms, Zelle indicated that it would provide redress for users in cases of unauthorized transfers in which a user’s account is accessed by a bad actor and used to transfer a payment,” the report continued. “However, EWS’ response also indicated that neither Zelle nor its parent bank owners would reimburse users fraudulently induced by a bad actor into making a payment on the platform.”
Still, the data suggest banks did repay at least some of the funds stolen from scam victims about 10 percent of the time. Fooshee said he’s surprised that number is so high.
“That banks are paying victims of authorized payment fraud scams anything at all is noteworthy,” he said. “That’s money that they’re paying for out of pocket almost entirely for goodwill. You could argue that repaying all victims is a sound strategy especially in the climate we’re in but to say that it should be what all banks do remains an opinion until Congress changes the law.”
However, when it comes to reimbursing victims of fraud and account takeovers, the report suggests banks are stiffing their customers whenever they can get away with it. “Overall, the four banks that provided complete data sets indicated that they reimbursed only 47% of the dollar amount of fraud claims they received,” the report notes.
How did the banks behave individually? From the report:
-In 2021 and the first six months of 2022, PNC Bank indicated that its customers reported 10,683 cases of unauthorized payments totaling over $10.6 million, of which only 1,495 cases totaling $1.46 were refunded to consumers. PNC Bank left 86% of its customers that reported cases of fraud without recourse for fraudulent activity that occurred on Zelle.
-Over this same time period, U.S. Bank customers reported a total of 28,642 cases of unauthorized transactions totaling over $16.2 million, while only refunding 8,242 cases totaling less than $4.7 million.
-In the period between January 2021 and September 2022, Bank of America customers reported 81,797 cases of unauthorized transactions, totaling $125 million. Bank of America refunded only $56.1 million in fraud claims – less than 45% of the overall dollar value of claims made in that time.
–Truist indicated that the bank had a much better record of reimbursing defrauded customers over this same time period. During 2021 and the first half of 2022, Truist customers filed 24,752 unauthorized transaction claims amounting to $24.4 million. Truist reimbursed 20,349 of those claims, totaling $20.8 million – 82% of Truist claims were reimbursed over this period. Overall, however, the four banks that provided complete data sets indicated that they reimbursed only 47% of the dollar amount of fraud claims they received.
Fooshee said there has long been a great deal of inconsistency in how banks reimburse unauthorized fraud claims — even after the Consumer Financial Protection Bureau (CPFB) came out with guidance on what qualifies as an unauthorized fraud claim.
“Many banks reported that they were still not living up to those standards,” he said. “As a result, I imagine that the CFPB will come down hard on those with fines and we’ll see a correction.”
Fooshee said many banks have recently adjusted their reimbursement policies to bring them more into line with the CFPB’s guidance from last year.
“So this is heading in the right direction but not with sufficient vigor and speed to satisfy critics,” he said.
Seth Ruden is a payments fraud expert who serves as director of global advisory for digital identity company BioCatch. Ruden said Zelle has recently made “significant changes to its fraud program oversight because of consumer influence.”
“It is clear to me that despite sensational headlines, progress has been made to improve outcomes,” Ruden said. “Presently, losses in the network on a volume-adjusted basis are lower than those typical of credit cards.”
But he said any failure to reimburse victims of fraud and account takeovers only adds to pressure on Congress to do more to help victims of those scammed into authorizing Zelle payments.
“The bottom line is that regulations have not kept up with the speed of payment technology in the United States, and we’re not alone,” Ruden said. “For the first time in the UK, authorized payment scam losses have outpaced credit card losses and a regulatory response is now on the table. Banks have the choice right now to take action and increase controls or await regulators to impose a new regulatory environment.”
Sen. Warren’s report is available here (PDF).
There are, of course, some versions of the Zelle fraud scam that may be confusing financial institutions as to what constitutes “authorized” payment instructions. For example, the variant I wrote about earlier this year began with a text message that spoofed the target’s bank and warned of a pending suspicious transfer.
Those who responded at all received a call from a number spoofed to make it look like the victim’s bank calling, and were asked to validate their identities by reading back a one-time password sent via SMS. In reality, the thieves had simply asked the bank’s website to reset the victim’s password, and that one-time code sent via text by the bank’s site was the only thing the crooks needed to reset the target’s password and drain the account using Zelle.
None of the above discussion involves the risks affecting businesses that bank online. Businesses in the United States do not enjoy the same fraud liability protection afforded to consumers, and if a banking trojan or clever phishing site results in a business account getting drained, most banks will not reimburse that loss.
This is why I have always and will continue to urge small business owners to conduct their online banking affairs only from a dedicated, access restricted and security-hardened device — and preferably a non-Windows machine.
For consumers, the same old advice remains the best: Watch your bank statements like a hawk, and immediately report and contest any charges that appear fraudulent or unauthorized.
Erlik 2 - Vulnerable-Flask-App

Today, with the spread of information technology systems, investments in the field of cyber security have increased to a great extent. Vulnerability management, penetration tests and various analyzes are carried out to accurately determine how much our institutions can be affected by cyber threats. With Tenable Nessus, the industry leader in vulnerability management tools, an IP address that has just joined the corporate network, a newly opened port, exploitable vulnerabilities can be determined, and a python application that can work integrated with Tenable Nessus has been developed to automatically identify these processes.
git clone https://github.com/anil-yelken/Nessus-Automation cd Nessus-Automation sudo pip3 install requirements.txt
The SIEM IP address in the codes should be changed.
In order to detect a new IP address exactly, it was checked whether the phrase "Host Discovery" was used in the Nessus scan name, and the live IP addresses were recorded in the database with a timestamp, and the difference IP address was sent to SIEM. The contents of the hosts table were as follows:
Usage: python finding-new-ip-nessus.py
By checking the port scans made by Nessus, the port-IP-time stamp information is recorded in the database, it detects a newly opened service over the database and transmits the data to SIEM in the form of "New Port:" port-IP-time stamp. The result observed by SIEM is as follows:
Usage: python finding-new-port-nessus.py
In the findings of vulnerability scans made in institutions and organizations, primarily exploitable vulnerabilities should be closed. At the same time, it records the vulnerabilities in the database that can be exploited with metasploit in the institutions and transmits this information to SIEM when it finds a different exploitable vulnerability on the systems. Exploitable vulnerabilities observed by SIEM:

Three men in the United Kingdom were arrested this month for attempting to assault a local man and steal his virtual currencies. The incident is the latest example of how certain cybercriminal communities are increasingly turning to physical violence to settle scores and disputes.
Shortly after 11 p.m. on September 6, a resident in the Spalding Common area in the district of Lincolnshire, U.K. phoned police to say three men were acting suspiciously, and had jumped a nearby fence.
“The three men made off in a VW Golf and were shortly stopped nearby,” reads a statement by the Lincolnshire Police. “The car was searched by officers who found an imitation firearm, taser, a baseball bat and police uniform in the boot.”
Thomas Green, 23, Rayhan Miah, 23, and Leonardo Sapiano, 24 were all charged with possession of the weapons, and “with intent to cause loss to another to make an unwarranted demand of Crypto Currency from a person.”
KrebsOnSecurity has learned that the defendants were in Spalding Common to pay a surprise visit to a 19-year-old hacker known by the handles “Discoli,” “Disco Dog,” and “Chinese.” In December 2020, Discoli took credit for hacking and leaking the user database for OGUsers, a forum overrun with people looking to buy, sell and trade access to compromised social media accounts.
Reached via Telegram, Discoli confirmed that police believe the trio was trying to force their way into his home in Spalding Common, and that one of them was wearing a police uniform when they approached his residence.
“They were obvious about being fake police, so much so that one of our neighbours called,” Discoli said in an instant message chat. “That call led to the arrests. Their intent was for robbery/blackmail of crypto, I just happened to not be home at the time.”
The Lincolnshire Police declined to comment for this story, citing an ongoing investigation.
Discoli said he didn’t know any of the men charged, but believes they were hired by one of his enemies. And he said his would-be assailants didn’t just target him specifically.
“They had a list of people they wanted to hit consecutively as far as I know,” he said.
The foiled robbery is the latest drama tied to members of certain criminal hacking communities who are targeting one another with physical violence, by making a standing offer to pay thousands of dollars to anyone in the target’s region who agrees to carry out the assaults.
Last month, a 21-year-old New Jersey man was arrested and charged with stalking in connection with a federal investigation into groups of cybercriminals who are settling scores by hiring people to carry out physical attacks on their rivals.
Prosecutors say Patrick McGovern-Allen recently participated in several of these schemes — including firing a handgun into a Pennsylvania home and torching a residence in another part of the state with a Molotov Cocktail.
McGovern-Allen and the three U.K. defendants are part of an online community that is at the forefront of a dangerous escalation in coercion and intimidation tactics increasingly used by competing cybercriminal groups to steal cryptocurrency from one another and to keep their rivals in check.
The Telegram chat channels where these young men transact have hundreds to thousands of members each, and some of the more interesting solicitations on these communities are job offers for in-person assignments and tasks that can be found if one searches for posts titled, “If you live near,” or “IRL job” — short for “in real life” job.
A number of these classified ads are in service of performing “brickings,” where someone is hired to visit a specific address and toss a brick through the target’s window. Indeed, prior to McGovern-Allen’s arrest, his alleged Telegram persona bragged that he’d carried out several brickings for hire.
Many of the individuals involved in paying others to commit these physical attacks are also frequent participants in Telegram chat channels focused singularly on SIM swapping, a crime in which identity thieves hijack a target’s mobile phone number and use that to wrest control over the victim’s various online accounts and identities.
Unsurprisingly, the vast majority of people currently being targeted for brickings and other real-life physical assaults via Telegram tend to be other cybercriminals involved in SIM swapping crimes (or individuals on the periphery of that scene).
The United Kingdom is home to a number of young men accused of stealing millions of dollars worth of cryptocurrencies via SIM swapping. Joseph James O’Connor, a.k.a. “Plugwalk Joe”, was arrested in Spain in July 2021 under an FBI warrant on 10 counts of offenses related to unauthorized computer access and cyber bullying. U.S. investigators say O’Connor also played a central role in the 2020 intrusion at Twitter, wherein Twitter accounts for top celebrities and public figures were forced to tweet out links to cryptocurrency scams. O’Connor is currently fighting extradition to the United States.
Robert Lewis Barr, a 25-year-old Scottish man who allegedly stole more than $8 million worth of crypto, was arrested on an FBI warrant last year and is also fighting his extradition. U.S. investigators say Barr SIM swapped a U.S. bitcoin broker in 2017, and that he spent much of the stolen funds throwing lavish parties at rented luxury apartments in central Glasgow.
In many ways, these violence-as-a-service incidents are a natural extension of “swatting,” wherein fake bomb threats, hostage situations and other violent scenarios are phoned in to police as part of a scheme to trick them into visiting potentially deadly force on a target’s address. According to prosecutors, both Barr and O’Connor have a history of swatting their enemies and their SIM swapping victims.
Graph Crawler is the most powerful automated testing toolkit for any GraphQL endpoint.
NEW: Can search for endpoints for you using Escape Technology's powerful Graphinder tool. Just point it towards a domain and add the '-e' option and Graphinder will do subdomain enumeration + search popular directories for GraphQL endpoints. After all this GraphCrawler will take over and work through each find.
It will run through and check if mutation is enabled, check for any sensitive queries available, such as users and files, and it will also test any easy queries it find to see if authentication is required.
If introspection is not enabled on the endpoint it will check if it is an Apollo Server and then can run Clairvoyance to brute force and grab the suggestions to try to build the schema ourselves. (See the Clairvoyance project for greater details on this). It will then score the findings 1-10 with 10 being the most critical.
If you want to dig deeper into the schema you can also use graphql-path-enum to look for paths to certain types, like user IDs, emails, etc.
I hope this saves you as much time as it has for me

Recon is one of the most important phases that seem easy but takes a lot of effort and skill to do right. One needs to know about the right tools, correct queries/syntax, run those queries, correlate the information, and sanitize the output. All of this might be easy for a seasoned infosec/recon professional to do, but for rest, it is still near to magic. How cool it will be to ask a simple question like "Find me an open Memcached server in Singapore with UDP support?" or "How many IP cameras in Singapore are using default credentials?" in a chat and get the answer?
The integration of GPT-3, deep learning-based language models to produce human-like text, with well-known recon tools like Shodan, is the foundation of ReconPal. ReconPal also supports using voice commands to execute popular exploits and perform reconnaissance.

$ cd deploy/vagrant && vagrant destroy
In preparation for a VBS AV Evasion Stream/Video I was doing some research for Office Macro code execution methods and evasion techniques.
The list got longer and longer and I found no central place for offensive VBA templates - so this repo can be used for such. It is very far away from being complete. If you know any other cool technique or useful template feel free to contribute and create a pull request!
Most of the templates in this repo were already published somewhere. I just copy pasted most templates from ms-docs sites, blog posts or from other tools.

Microsoft today released updates to fix a record 141 security vulnerabilities in its Windows operating systems and related software. Once again, Microsoft is patching a zero-day vulnerability in the Microsoft Support Diagnostics Tool (MSDT), a service built into Windows. Redmond also addressed multiple flaws in Exchange Server — including one that was disclosed publicly prior to today — and it is urging organizations that use Exchange for email to update as soon as possible and to enable additional protections.
In June, Microsoft patched a vulnerability in MSDT dubbed “Follina” that had been used in active attacks for at least three months prior. This latest MSDT bug — CVE-2022-34713 — is a remote code execution flaw that requires convincing a target to open a booby-trapped file, such as an Office document. Microsoft this month also issued a different patch for another MSDT flaw, tagged as CVE-2022-35743.
The publicly disclosed Exchange flaw is CVE-2022-30134, which is an information disclosure weakness. Microsoft also released fixes for three other Exchange flaws that rated a “critical” label, meaning they could be exploited remotely to compromise the system and with no help from users. Microsoft says addressing some of the Exchange vulnerabilities fixed this month requires administrators to enable Windows Extended protection on Exchange Servers. See Microsoft’s blog post on the Exchange Server updates for more details.
“If your organization runs local exchange servers, this trio of CVEs warrant an urgent patch,” said Kevin Breen, director of cyber threat research for Immerse Labs. “Exchanges can be treasure troves of information, making them valuable targets for attackers. With CVE-2022-24477, for example, an attacker can gain initial access to a user’s host and could take over the mailboxes for all exchange users, sending and reading emails and documents. For attackers focused on Business Email Compromise this kind of vulnerability can be extremely damaging.”
The other two critical Exchange bugs are tracked as CVE-2022-24516 and CVE-2022-21980. It’s difficult to believe it’s only been a little more than a year since malicious hackers worldwide pounced in a bevy of zero-day Exchange vulnerabilities to remotely compromise the email systems for hundreds of thousands of organizations running Exchange Server locally for email. That lingering catastrophe is reminder enough that critical Exchange bugs deserve immediate attention.
The SANS Internet Storm Center‘s rundown on Patch Tuesday warns that a critical remote code execution bug in the Windows Point-to-Point Protocol (CVE-2022-30133) could become “wormable” — a threat capable of spreading across a network without any user interaction.
“Another critical vulnerability worth mentioning is an elevation of privilege affecting Active Directory Domain Services (CVE-2022-34691),” SANS wrote. “According to the advisory, ‘An authenticated user could manipulate attributes on computer accounts they own or manage, and acquire a certificate from Active Directory Certificate Services that would allow elevation of privilege to System.’ A system is vulnerable only if Active Directory Certificate Services is running on the domain. The CVSS for this vulnerability is 8.8.”
Breen highlighted a set of four vulnerabilities in Visual Studio that earned Microsoft’s less-dire “important” rating but that nevertheless could be vitally important for the security of developer systems.
“Developers are empowered with access to API keys and deployment pipelines that, if compromised, could be significantly damaging to organizations,” he said. “So it’s no surprise they are often targeted by more advanced attackers. Patches for their tools should not be overlooked. We’re seeing a continued trend of supply-chain compromise too, making it vital that we ensure developers, and their tools, are kept up-to-date with the same rigor we apply to standard updates.”
Greg Wiseman, product manager at Rapid7, pointed to an interesting bug Microsoft patched in Windows Hello, the biometric authentication mechanism for Windows 10. Microsoft notes that the successful exploitation of the weakness requires physical access to the target device, but would allow an attacker to bypass a facial recognition check.
Wiseman said despite the record number of vulnerability fixes from Redmond this month, the numbers are slightly less dire.
“20 CVEs affect their Chromium-based Edge browser and 34 affect Azure Site Recovery (up from 32 CVEs affecting that product last month),” Wiseman wrote. “As usual, OS-level updates will address a lot of these, but note that some extra configuration is required to fully protect Exchange Server this month.”
As it often does on Patch Tuesday, Adobe has also released security updates for many of its products, including Acrobat and Reader, Adobe Commerce and Magento Open Source. More details here.
Please consider backing up your system or at least your important documents and data before applying system updates. And if you run into any problems with these updates, please drop a note about it here in the comments.
