Which of the following is NOT a password cracking tool?

• A. John the Ripper
• B. Ophcrack
• C. L0phtCrack
• D. Netcat

Answer: (D)

Password cracking tools are built to recover or guess passwords by testing candidates or derived hashes. John the Ripper, Ophcrack, and L0phtCrack are all designed for that purpose, using dictionaries, brute-force methods, or precomputed tables against password hashes. Netcat, on the other hand, is a networking utility used to read and write data across network connections, open ports, and transfer data; it does not perform password cracking by itself. So Netcat is not a password cracking tool.
