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
• Windows Security Event ID 4656/4663 (Object Access Auditing)
• LSASS SACL auditing enabled (Windows 10+)
• Registry auditing for SAM hive access
