System Security Management,
L0stat generates an statistical report of strength of NT accounts and passwords.
This utility gets the L0phtCrack* result files or the LC3 exported text results file and treats the data to give the NT or security administrator a global view of security of their SAM database.
As a way to discover NT passwords, L0phtCrack are LC3 great tools.
But if you don't want to know the passwords themselves but the global security view of passwords quality, you should go one step beyond. For example, how you can evaluate the security level of an NT entreprise's database with 1000 accounts ?
There is the place for L0stat. L0stat doesn't replaces L0phtCrack. L0stat is a reporting tool of data retrieved with L0phtCrack or LC3.
