ezEmu - Simple Execution Of Commands For Defensive Tuning/Research
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.
Windows
See /Linux for ELF
ezEmu is compiled as
parent.exe
to simplify process trees, and will track (and also kill) child processes to enable easy searches in logs/dashboards.Current execution techniques include:
- Cmd.exe (T1059.003)
- PowerShell (T1059.001)
- Unmanaged PowerShell (T1059.001)
- CreateProcess() API (T1106)
- WinExec() API (T1106)
- ShellExecute (T1106)
- Windows Management Instrumentation (T1047)
- VBScript (T1059.005)
- Windows Fiber
- WMIC XSL Script/Squiblytwo (T1220)
- Microsoft Word VBA Macro (T1059)
- Python (T1059.006)
Usage/Demo
ezEmu is an interactive terminal application and works much better if you run from cmd.exe
Compile with reference to a few local DLL dependencies
(ex:
csc /r:Microsoft.Office.Interop.Word.dll,Microsoft.Vbe.Interop.dll,System.Management.Automation.dll parent.cs
)Feedback/Contribute
This started as just simple personal research/putzing and is definitely not intended to be "clean code" (this is very much Jamie-code
TODO: Log output file (perhaps), more CTI + learning >> more execution techniques (always)
