logoL0phtCrack 6

L0phtCrack is a password auditing and recovery application originally produced by Mudge from L0pht Heavy Industries. It is used to test password strength and sometimes to recover lost Microsoft Windows passwords, by using dictionary, brute-force, hybrid attacks, and rainbow tables. It was one of the crackers’ tools of choice, although most use old versions because of its low price and high availability.

Security experts from industry, government, and academia agree that weak passwords represent one of the ten most critical Internet security threats, and are receiving more attention as a source of vulnerability, both on client desktop computers and in networks. L0phtCrack identifies and assesses password vulnerability over local machines and networks in a streamlined application, with built-in reports and remediation tools.
