L0phtCrack is a password auditing and recovery tool. It can:

Capture password hashes over the network (e.g., via SMB).

Crack password hashes using dictionary, brute-force, or hybrid attacks.

It’s particularly effective when used on SMB-based challenge-response authentication (NTLM/LM) captured via packet sniffing.

From CEH v13 Courseware:

Module 4: Enumeration

Module 6: Malware Threats

CEH v13 Study Guide states:

“L0phtCrack can sniff SMB authentication exchanges from network traffic and extract NTLM password hashes to crack them offline.”

Incorrect Options:

A: This is possible (hence A is wrong).

B: Netbus is a backdoor/trojan tool.

C: NTFSDOS is used to read NTFS partitions under DOS, not for password cracking.
