Icebreaker

Last Modification

Description of the Tool:

Break the ice with that cute Active Directory environment over there. When you're cold and alone staring in at an Active Directory party but don't possess even a single AD credential to join the fun, this tool's for you.

Sequentially automates 5 internal network attacks against Active Directory to deliver you plaintext credentials.

  1. Reverse bruteforce: Automatically acquires a list of usernames and tests each one with two of the most common AD passwords (more than two attempts may trigger account lockout policies)

  2. Upload to network shares: Capture users' passwords with malicious file uploads to available network shares

  3. Poison broadcast network protocols: Uses common network protocols to trick users' computers into sending you passwords

  4. Man-in-the-middle SMB connections: Performs remote command execution against AD computers in order to gather passwords

  5. Poison IPv6 DNS: Exploits DNS to trick AD computers into sending their users' passwords to you
