Detecting Credential Dumping Techniques

Overview

Credential dumping (MITRE ATT&CK T1003) is a post-exploitation technique where adversaries extract authentication credentials from OS memory, registry hives, or domain controller databases. This skill covers detection of LSASS memory access via Sysmon Event ID 10 (ProcessAccess), SAM registry hive export via reg.exe, NTDS.dit extraction via ntdsutil/vssadmin, and comsvcs.dll MiniDump abuse. Detection rules analyze GrantedAccess bitmasks, suspicious calling processes, and known tool signatures.

When to Use

• When investigating security incidents that require detecting credential dumping techniques
• When building detection rules or threat hunting queries for this domain
• When SOC analysts need structured procedures for this analysis type
• When validating security monitoring coverage for related attack techniques

Prerequisites

• Sysmon v14+ deployed with ProcessAccess logging (Event ID 10) for lsass.exe
• Windows Security audit policy enabling process creation (Event ID 4688) with command line logging
• Splunk or Elastic SIEM ingesting Sysmon and Windows Security logs
