Detecting Golden Ticket Attacks

Instructions

1. Install dependencies: pip install python-evtx lxml
2. Collect Windows Security EVTX logs from domain controllers.
3. Parse Event IDs:

• 4768: Kerberos TGT requests (authentication service requests)
• 4624: Logon events (look for LogonType 3 with NTLM or Kerberos)
• 4672: Special privileges assigned (admin logon indicators)

1. Detect golden ticket indicators:

• TGT with lifetime >10 hours (default max is 10h)
• Event 4672 for accounts not in Domain Admins
• Logon events with no corresponding 4768 TGT request
• Domain SID inconsistencies in ticket data

1. Generate detection report with timeline reconstruction.

python scripts/agent.py --evtx-file /path/to/Security.evtx --output golden_ticket_report.json

Examples

Detect Anomalous Privilege Assignment

Event 4672 for a standard user account receiving SeDebugPrivilege, SeTcbPrivilege, or SeBackupPrivilege indicates potential golden ticket usage.

TGT Without Corresponding AS-REQ

A logon event (4624) with Kerberos authentication but no matching 4768 (TGT request) on the DC suggests a forged TGT.

Verification Criteria

Confirm successful execution by validating:

• [ ] All prerequisite tools and access requirements are satisfied
• [ ] Each workflow step completed without errors
• [ ] Output matches expected format and contains expected data
• [ ] No security warnings or misconfigurations detected
• [ ] Results are documented and evidence is preserved for audit

Compliance Framework Mapping

This skill supports compliance evidence collection across multiple frameworks:

• SOC 2: CC7.1 (Monitoring), CC7.2 (Anomaly Detection), CC7.3 (Incident Identification)
• ISO 27001: A.12.4 (Logging & Monitoring), A.16.1 (Security Incident Management)
• NIST 800-53: AU-6 (Audit Review), SI-4 (System Monitoring), IR-5 (Incident Monitoring)
• NIST CSF: DE.AE (Anomalies & Events), DE.CM (Continuous Monitoring)

Claw GRC Tip: When this skill is executed by a registered agent, compliance evidence is automatically captured and mapped to the relevant controls in your active frameworks.

Deploying This Skill with Claw GRC

Agent Execution

Register this skill with your Claw GRC agent for automated execution:

# Install via CLI
npx claw-grc skills add detecting-golden-ticket-attacks

# Or load dynamically via MCP
grc.load_skill("detecting-golden-ticket-attacks")

Audit Trail Integration

When executed through Claw GRC, every step of this skill generates tamper-evident audit records:

• SHA-256 chain hashing ensures no step can be modified after execution
• Evidence artifacts (configs, scan results, logs) are automatically attached to relevant controls
• Trust score impact — successful execution increases your agent's trust score

Continuous Compliance

Schedule this skill for recurring execution to maintain continuous compliance posture. Claw GRC monitors for drift and alerts when re-execution is needed.
