CrackMapExec (CME): The Swiss Army Knife for Active Directory Attacks

CrackMapExec (CME) is a powerful open-source post-exploitation and Active Directory auditing tool written in Python. Originally built for Red Teamers and pentesters, it allows lateral movement, credentials dumping, privilege checks, and network enumeration across Windows domains — all through a single unified interface. Its versatility and efficiency make it a must-have tool when conducting internal network assessments.

Why is CME essential in network penetration tests?

1. Comprehensive Network Enumeration: Gather detailed data about users, hosts, groups, sessions, shares, domain policies, and more — all from within the AD environment.
2. Post-Exploitation Capabilities: CME can dump NTLM/Kerberos hashes, run remote commands, and facilitate lateral movement through the network.
3. Privilege Escalation & Testing: Easily verify if a user has Local Admin, Domain Admin, or other elevated rights. Detect common misconfigurations like Unconstrained Delegation.
4. Multi-Protocol Support: CME supports a variety of Windows protocols for maximum coverage:
   
   • 445/TCP SMB – File/Printer share access.
     
   • 5985/5986 WinRM – Remote PowerShell execution.
     
   • 1433 MSSQL – SQL query execution and injection.
     
   • 389 LDAP – Advanced Active Directory queries.

Practical Example: Extracting Local SAM Hashes via SMB

Let’s say you have credentials (or weak default ones) and want to identify local admin accounts across an internal subnet (192.168.1.0/24). You could try extracting password hashes from the SAM database like this:

crackmapexec smb 192.168.1.0/24 -u 'Administrator' -p 'Password123!' --sam

Explanation:

• Scans the /24 subnet for reachable SMB shares.
• Authenticates with Administrator:Password123! on each machine.
• If successful, dumps local SAM password hashes.
• These hashes can be cracked offline or reused in Pass-the-Hash attacks.

Final Thoughts:
CrackMapExec remains one of the most robust post-exploitation tools for assessing Windows domain environments. Its support for critical protocols (SMB, WinRM, MSSQL, LDAP), seamless enumeration, and post-ex capabilities make it a key asset in the Red Team arsenal. When used responsibly, it uncovers dangerous misconfigs and weak credentials before adversaries do.
