L0phtCrack

Password CrackingOperating System Audit

L0phtCrack Description
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.
The application was produced by @stake after the L0pht merged with @stake in 2000. @stake was then acquired by Symantec in 2004. Symantec later stopped selling this tool to new customers, citing US Government export regulations, and discontinued support in December 2006.
In January 2009, L0phtCrack was acquired by the original authors Zatko, Wysopal, and Rioux from Symantec. L0phtCrack 6 was announced on 11 March 2009 at the SOURCE Boston Conference. L0phtCrack 6 contains support for 64-bit Windows platforms as well as upgraded rainbow tables support. L0phtCrack 7 was released on 30 August 2016, seven years after the previous release. L0phtCrack 7 supports GPU cracking, increasing performance up to 500 times that of previous versions.
