Projects
RunPE In Memory
github.com/aaaddress1/RunPE-In-Memory・538 Stars
Run Windows PE File directly in memory like an Application Loader.
PR0CESS
github.com/aaaddress1/PR0CESS・513 Stars
Abuse the Windows internal process design to achieve wild attacks used by APT groups e.g. Process Herpaderping, Process Ghosting, UAC Bypassing.
Skrull
github.com/aaaddress1/Skrull・408 Stars
Skrull is a malware DRM, that prevents Automatic Sample Submission by AV/EDR and Signature Scanning from Kernel. It generates launchers that can run malware on the victim using the Process Ghosting technique. Also, launchers are totally anti-copy and naturally broken when got submitted.
wowInjector
github.com/aaaddress1/wowInjector・144 Stars
Inject payload to WOW64(Windows 32 on Windows 64) process via exploit 32-bit thread snapshot. This trick makes us possible to do malicious attacks and bypass Antivirus agents at the same time, e.g. Injection, Hollowing, Dropper, etc.
It's a proof-of-concept of the talk of HITB 2021. There are more details about reversing the whole WOW64 layer by Microsoft and abuse, see Rebuild The Heaven's Gate: from 32 bit Hell back to Heaven Wonderland.
