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)

Note: You need to enable some macro related trust center settings for the Word stuffz to work – https://support.office.com/en-us/article/enable-or-disable-macros-in-office-files-12b036fd-d140-4e74-b45e-16fed1a7e5c6. You also need Python installed and the PATH variable set for #12

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™️). That said, I am happy to accept issues and further suggestions!
TODO: Log output file (perhaps), more CTI + learning >> more execution techniques (always)
