TiEtwAgent : PoC Memory Injection Detection Agent Based On ETW, For Offensive And Defensive Research Purposes

TiEtwAgent project was created to research, build and test different memory injection detection use cases and bypass techniques. The agent utilizes Microsoft-Windows-Threat-Intelligence event tracing provider, as a more modern and stable alternative to Userland-hooking, with the benefit of Kernel-mode visibility.

The project depends on the microsoft/krabsetw library for ETS setup and consumption.

Adding New Detections

Detection functions can be easily added in DetectionLogic.cpp, and called from detect_event(GenericEvent evt) for any source event type. Support for new event fields can be easily added by appending their name to the map in GenericEvent class declaration.

Setup Instructions

Assuming you do not have a Microsoft-trusted signing certificate:

  • Put your machine in the test signing mode with bcdedit
  • Generate a self-signed certificate with ELAM and Code Signing EKU
  • Sign TiEtwAgent.exe and your ELAM driver with the certificate
  • ./TiEtwAgent install
  • net start TiEtwAgent
  • Look for logs, by default in C:\Windows\Temp\TiEtwAgent.txt
