ezEmuELF

ezEmu enables users to test adversary behaviors via various execution techniques. Sort of like an "offensive framework for blue teamers", ezEmu does not have any networking/C2 capabilities and rather focuses on creating local test telemetry.

ezEmu is compiled as parent to simplify process trees, and will track (and also kill) child processes to enable easy searches in logs/dashboards.

Current execution techniques include:

  • sh via system() (T1059.004)
  • Python via popen() (T1059.006)
  • Perl via system() (T1059)

Usage/Demo

ezEmu is an interactive terminal application and works much better if you run from a terminal

ezEmuELF Demo

Compiled with GCC (ex: gcc -pthread parent.c -o parent)
