What is L0phtcrack?

• A. A vulnerability scanner.
• B. A password auditing and recovery application.
• C. A firewall.
• D. A file integrity monitor.

Answer: (B)

L0phtcrack is a password auditing and recovery tool used to assess how strong Windows passwords are by attempting to crack or recover password hashes offline. It targets hashed passwords stored by Windows (like LM/NTLM hashes) and uses methods such as dictionary attacks, brute force, and rainbow tables to reveal weak or common passwords. The goal is to help administrators enforce stronger password policies and reduce the risk of unauthorized access. It is not a vulnerability scanner, firewall, or a file integrity monitor.
