Dirty Vanity

A POC for the new injection technique, abusing windows fork API to evade EDRs.

Usage

DirtyVanity.exe [TARGET_PID_TO_REFLECT]

Runtime steps

• Allocate and write shellcode to [TARGET_PID_TO_REFLECT]
• Fork [TARGET_PID_TO_REFLECT] to a new process
• Set the forked process's start address to the cloned shellcode

Shellcode

The reflected shellcode works with ntdll API. It is generated from the included generation project shellcode_template, curtesy of https://github.com/rainerzufalldererste/windows_x64_shellcode_template

Shellcode customization

To customize the shellcode with ease:

• Edit the shellcode_template function inside the shellcode_template project, according to the instructions in https://github.com/rainerzufalldererste/windows_x64_shellcode_template
• Compile it
• Crop the shellcode_template function bytes using your faivorite PE parsing tool (eg IDA)
• Those bytes are position independet shellcode. place them in DirtyVanity.cpp
• Execute DirtyVanity to watch them get Reflected
