Detect OS credential dumping (MITRE T1003) targeting LSASS memory, the SAM database, NTDS.dit, and cached credentials by correlating EDR telemetry, Sysmon process-access events, and Windows security event logs. Use when hunting for Mimikatz-style credential theft, triaging an EDR alert on LSASS access, or scoping an incident after suspected credential dumping.

# Detecting T1003 Credential Dumping with EDR
## When to Use
- When hunting for credential theft activity in the environment
- After compromise indicators suggest attacker has elevated privileges
- When EDR alerts fire for LSASS access or suspicious process memory reads
- During incident response to determine scope of credential compromise
- When auditing LSASS protection controls (Credential Guard, RunAsPPL)
## Prerequisites
- EDR agent deployed with LSASS access monitoring (CrowdStrike, Defender for Endpoint, SentinelOne)
- Sysmon Event ID 10 (ProcessAccess) with LSASS-specific filters
