L0phtCrack is a
password auditing and recovery application (now called LC5), originally produced by Mudgefrom L0phtHeavy Industries. It is used to test password strength and sometimes to recover lost Microsoft Windowspasswords, by using dictionary, brute-force, and hybrid attacks.cite web |url=http://sectools.org/tools2.html |title=Top 100 Network Security Tools (Page 2/4) |accessdate=2008-09-18] It was one of the crackers' tools of choice, although most use old versions because of its price and low availability.
The application was produced by
@stakeafter the L0phtmerged with @stake in 2000. @stake was then acquired by Symantecin 2004.
