Which of the following is an example of a password cracking tool?

• A. John the Ripper
• B. Scapy
• C. Fiddler
• D. NetStumbler

Answer: (A)

Password cracking tools are used to test how resistant a password or password storage is by trying many guesses or reversing hashed passwords. John the Ripper fits this role because it is designed to audit password strength, using methods like dictionary attacks (trying common words), brute-force (trying all possible combinations), and other rules-based approaches. It can operate on password hashes from different systems, making it a staple in security assessments when you have permission to test. The other tools serve different purposes: Scapy is for crafting and analyzing network packets; Fiddler acts as a web debugging proxy to inspect HTTP(S) traffic; NetStumbler is used to discover wireless networks and measure signal information. None of these are password cracking tools.
