Which tool is marketed as a rainbow-table-based Windows password cracker with a graphical user interface?

• A. L0phtCrack
• B. got-responded
• C. pwdump7
• D. ophcrack

Answer: (D)

Rainbow tables speed password cracking by using precomputed hash values, so a tool that is built around this idea and offers a graphical user interface is Ophcrack. Ophcrack is marketed specifically as a rainbow-table-based Windows password cracker and comes with a GUI, often shipped as a live CD for easy use on Windows machines. That combination of precomputed tables and a user-friendly interface is what sets it apart.

The other tools don’t fit that description. L0phtCrack is mainly an auditing/cracking tool that uses dictionary and brute-force methods and has a traditional interface rather than a rainbow-table-based GUI focus. Pwdump7 is used to dump Windows password hashes, not to crack them. The remaining option isn’t recognized as the rainbow-table-based Windows password cracker with GUI in the same way Ophcrack is.
