Stealing Credentials with a Security Support Provider (SSP)
Mimikatz provides attackers with several different ways to steal credentials from memory or extract them from Active Directory. One of the most interesting options is the MemSSP command. An adversary can use this command to register a malicious Security Support Provider (SSP) on a Windows member server or domain controller (DC) — and that SSP will log all passwords in clear text for any users who log on locally to that system.
