What tool can crack Windows SMB passwords simply by listening to network traffic?

This statement is incorrect; capturing and cracking SMB passwords by listening to network traffic is a known attack vector, especially in older Windows versions or misconfigured environments.

Netbus is a remote access trojan (RAT), not a tool primarily used for sniffing and cracking SMB passwords from network traffic.

NTFSDOS is a utility for accessing NTFS partitions from a DOS environment, not a tool for sniffing and cracking SMB passwords.

L0phtcrack (now known as LC5) is a well-known password auditing and cracking tool specifically designed to recover Windows passwords. It can capture SMB password hashes by sniffing network traffic and then attempt to crack them using dictionary and brute-force methods.
