What it detects

This rule detects modification of the LSA Security Packages value to register a rogue Security Support Provider such as the lssc entry used by Lazarus. In the WithSecure Catching Lazarus research a malicious LSCC.dll is dropped into System32 and added as an SSP so it loads into lsass at boot. Attackers use SSP persistence to survive reboot and to capture credentials from the LSA process.
