- Add validated mitre_attack frontmatter to all 754 skills (286 distinct
techniques), verified against MITRE ATT&CK v19.1 via the official
mitreattack-python library: 0 revoked, deprecated, or invalid IDs
- Curate precise per-skill technique IDs for forensics, malware-analysis,
threat-intel, and red-team skills (e.g. DCSync -> T1003.006,
Kerberoasting -> T1558.003, Pass-the-Ticket -> T1550.003)
- Reconcile v19.1 tactic restructuring: Defense Evasion split into
Stealth (TA0005) and Defense Impairment (TA0112); revoked T1562.*
family and T1070.001/.002 remapped to active equivalents (T1685.*)
- Normalize word-split tags across 35 skills (remove filename-derived
stopword tags, add semantic cybersecurity tags)
- Add api-reference.md for 3 skills that were missing it
- Update README ATT&CK section with accurate v19.1 tactic distribution

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
Python 3.8+ for log analysis
Steps
Configure Sysmon to log ProcessAccess events targeting lsass.exe
Forward Sysmon Event ID 10 and Windows Event ID 4688 to SIEM
Create detection rules for known GrantedAccess patterns (0x1010, 0x1FFFFF)
Detect comsvcs.dll MiniDump and procdump.exe targeting LSASS PID
Alert on reg.exe SAM/SECURITY/SYSTEM hive export commands
Detect ntdsutil/vssadmin shadow copy creation for NTDS.dit theft
Correlate detections with user/host context for risk scoring
Expected Output
JSON report containing detected credential dumping indicators with technique classification, severity ratings, process details, MITRE ATT&CK mapping, and Splunk/Elastic detection queries.
