L0phtCrack

L0phtCrack is a password auditing and recovery application used to test password strength and security. It can crack various password hashes by using dictionary, brute force, hybrid attacks and rainbow tables.

What is L0phtCrack?

L0phtCrack is a password auditing and recovery application developed by Mudge from the hacking group L0pht Heavy Industries. It is used by information security professionals to test the strength of passwords and overall security of a system.

Some key features of L0phtCrack include:

  • Cracking various password hashes including LM, NTLM, Cisco IOS, MD5, SHA-1, SHA-2 etc. using dictionary, brute force, hybrid attacks and rainbow tables
  • Determining password strength by analyzing length, characters types, common patterns, dictionary words etc.
  • Integrating with Windows to easily extract password hashes from SAM/AD databases
  • Cracking hashes from extracted registry hives and online attacks
  • Running distributed attacks across multiple systems
  • Extensive password auditing and reporting features

L0phtCrack is one of the most popular password cracking tools used by system administrators, security professionals and hackers to evaluate the robustness of password policies and user credentials. While password cracking can be used for malicious purposes, L0phtCrack also serves a legitimate purpose for defense testing in an ethical manner.
