Description
Detects potential credential harvesting attempts through LSASS memory dumps using ProcDump. This rule identifies suspicious command-line patterns that combine memory dump flags (-ma, -mm, -mp) with LSASS-related process markers. LSASS (Local Security Authority Subsystem Service) contains sensitive authentication data including plaintext passwords, NTLM hashes, and Kerberos tickets in memory. Attackers commonly dump LSASS memory to extract credentials for lateral movement and privilege escalation.

Detection requirements
- Platform
- ContainersESXiLinuxmacOSWindows
The rule states no platform. This is derived from the 2 ATT&CK techniques it maps to.
- Log source product
- windows
- Log source category
- process_creation
Known benign triggers
- Another tool that uses command line flags similar to ProcDump
- Unlikely, because no one should dump an lsass process memory
MITRE ATT&CK mappings
0 exclusive techniques.This is coverage no other published rule has; it is not this rule's total technique count.
