Sep 2026 10:39:52 +0000 Subject: [PATCH 08/49] Add Lua-based nmap auto-installer with de novo CVE checker Implements complete Lua/Python integration for automated security scanning: - nmap_cve_checker.lua: Cross-platform nmap auto-installation (apt/yum/brew/winget) with de novo CVE detection via NVD queries, service version enumeration, and timestamp-stamped logging - lua_nmap_integration.py: Python wrapper orchestrating Lua script execution, result parsing, JSON export, and seamless AdPentestAI pipeline integration - LUA_NMAP_CVE_CHECKER_README.md: Comprehensive documentation covering usage, architecture, error handling, performance considerations, and development - test_lua_nmap_cve_checker.py: Full test suite validating script syntax, Lua installation detection, CVE result parsing, and JSON serialization - lua_nmap_cve_example.py: Five runnable examples demonstrating basic CVE checks, service detection, report parsing, AdPentestAI integration, and batch scanning Features: - Auto-detects and installs nmap across Linux/macOS/Windows - Queries NVD for de novo (newly discovered) CVEs per service - Generates text reports and JSON output formats - Graceful error handling with verbose timestamps - Cross-platform package manager support (apt/yum/brew/winget/pacman) Co-Authored-By: Claude Haiku 4.5 Claude-Session:

Runs via: nmap -p 88,389,636,3268,3269,445 --script ad-cve-6130 - nse/cve-de-novo.nse: version/port script mapping -sV output to de novo CVEs via an embedded curated catalog, with an optional live NVD keyword lookup. Runs via: nmap -sV --script cve-de-novo - nse/install-nse.sh: auto-installs nmap (apt/dnf/yum/pacman/brew/winget), copies the .nse files into nmap's scriptdir, and runs --script-updatedb. Supports --no-install and --uninstall. - adpentest/nse_integration.py: NSEIntegration class to install nmap, embed the scripts, and drive them via `nmap --script` from the framework. - nse/README.md: usage, installation, and verification docs. Both NSE scripts pass luac -p syntax validation. The LDAP RootDSE probe and NVD lookup degrade gracefully to a port-based assessment when a library is missing or the target filters the probe.

LDAP enumeration crashed on every run — enum_ldap, enum_policy, and SPNEnumerator.enumerate passed timeout= to ldap3.Server(), which only accepts connect_timeout. Raised "Server.__init__() got an unexpected keyword argument 'timeout'". Fixed all three call sites. 2. check_ports trusted a tarpit/accept-all responder that SYN-ACKs every port, reporting all 13 AD ports "open", fabricating a Domain Controller, and driving port-presence CVE checks to false positives. Added _looks_like_tarpit(): probe control ports that should be closed (1,4,7,8389,10389,33389,53389); if >=3 answer open, treat the host as a tarpit and suppress its port-based findings. Verified: ldap3.Server(connect_timeout=...) is accepted while the old timeout= reproduces the original TypeError; a simulated host listening on 3 control ports is detected as a tarpit, and a normal host is not.

Windows keeps winget -> pip. Verified: a missing binary (masscan) is installed end-to-end via apt-get and resolved on PATH; package-name resolution is correct across managers; the already-installed short-circuit still works.

Refactor the per-technique logic into _run_one() and add an "all" path that runs all five techniques per host and aggregates status, with per-technique detail. 2. is_usable_host let link-local/APIPA (169.254/16), reserved (255.255.255.255), and /24 network/broadcast (.0/.255) addresses through, so recon counted broadcast/APIPA noise as live hosts. Reject them; the DC and gateway are kept. Bump version to 1.2.4. Verified: junk addresses dropped while DC + gateway kept; technique="all" runs all five techniques with no "Unknown technique" error; py_compile and twine check pass.

events_parser: Parse Windows Security event XML into structured events - correlation_engine: Correlate 4768 (TGT) → 4769 (TGS) to detect forged tickets - kerberos_detector: Main detection engine with 6 scoring rules: * Rule 1: TGS without correlated TGT * Rule 2: Kerberos logon without TGT * Rule 3: Privilege escalation after suspicious Kerberos auth * Rule 4: krbtgt account modifications * Rule 5: Evidence tampering (log clearing, audit policy changes) * Rule 6: DCSync-like replication access - privilege_escalation: Detect escalation chains and lateral movement - findings_reporter: Export findings as CSV, JSON, and HTML reports Each detection rule implements multi-factor scoring (1-10) to reduce false positives. Prioritizes findings from CRITICAL (9+) to LOW (1-2).

📋 Interpretation Guidelines

+
    +
  • No single event proves a Golden Ticket. 4769 without 4768 can be a legitimate correlation gap.
    • +
  • Look for multiple signals together: +
      +
    • Missing 4768 for a TGS request
      • +
    • Account doesn't exist in AD (deleted/compromised)
      • +
    • Weak encryption (RC4, DES)
      • +
    • Privilege escalation immediately after auth
      • +
    • krbtgt changes or DCSync-like access
      • +
    +
    • +
  • Context matters: Evaluate against your environment's baseline and normal audit patterns.
    • +
  • Check audit policies: Missing 4768s may indicate gaps in auditing rather than attacks.

New functions: - Check-AuditPolicy: Queries audit policies on DC, detects if Kerberos auditing is enabled/disabled - Test-EventLogCoverage: Analyzes event log coverage and generates diagnostic warnings 2. New detection rule (Rule 7 - Audit Coverage Gap): - CRITICAL (score 8): Zero Security + KDC events despite analysis window - HIGH (score 6): Only Directory Service events, no Kerberos auth events - MEDIUM (score 3): Very low Security event volume (<5 events in hours) - Provides remediation: Enable with auditpol /set /category:"Kerberos..." 3. Enhanced output diagnostics: - Display event coverage at start of analysis - Show audit policy status with remediation guidance - Display event counts in analysis results - Flag when audit gaps prevent reliable detection Impact: Clarifies why detection may find no findings when audit policies are misconfigured, and provides actionable remediation steps.

ce533f205f9c2dbb06580e7a70d53b9294c313e1 Mon Sep 17 00:00:00 2001 From: Claude Date: Wed, 16 Sep 2026 19:25:30 +0000 Subject: [PATCH 42/49] Add accused-accounts analyzer and standalone detection CLI MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - AccusedAccountsAnalyzer: correlates findings to identify Primary Suspects, Forged Ticket Users, Escalation Chains, and Service Accounts with multi-factor scoring and JSON export - CLI runner (python -m adpentest.detection): accepts JSON/CSV event feeds, runs full detection pipeline, exports findings + accused-accounts reports - Demo mode with realistic Golden Ticket attack chain simulation (DCSync → forged TGS → Pass-the-Ticket → privilege escalation) Co-Authored-By: Claude Opus 4.6 Claude-Session:

20:43:40 +0000 Subject: [PATCH 44/49] feat(detection): configurable known_domains with MEUHEDET.CO.IL - Add known_domains parameter to KerberosGoldenTicketDetector - Auto-detect domains from both TGT and TGS events when not configured - Replace hardcoded domain names with dynamic domain validation - Add --domain CLI argument for explicit domain configuration - Update demo events and Colab notebook to use MEUHEDET.CO.IL domain - Add _auto_detect_domains() deriving NetBIOS+FQDN variants - Include known_domains in get_summary() output Co-Authored-By: Claude Opus 4.6 Claude-Session:

text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * Add Kerberos Golden Ticket detection engine with privilege escalation analysis Implement comprehensive forensic detection module for Golden Ticket attacks: - events_parser: Parse Windows Security event XML into structured events - correlation_engine: Correlate 4768 (TGT) → 4769 (TGS) to detect forged tickets - kerberos_detector: Main detection engine with 6 scoring rules: * Rule 1: TGS without correlated TGT * Rule 2: Kerberos logon without TGT * Rule 3: Privilege escalation after suspicious Kerberos auth * Rule 4: krbtgt account modifications * Rule 5: Evidence tampering (log clearing, audit policy changes) * Rule 6: DCSync-like replication access - privilege_escalation: Detect escalation chains and lateral movement - findings_reporter: Export findings as CSV, JSON, and HTML reports Each detection rule implements multi-factor scoring (1-10) to reduce false positives. Prioritizes findings from CRITICAL (9+) to LOW (1-2). Co-Authored-By: Claude Haiku 4.5 Claude-Session: https://claude.ai/code/session_01A7LqcMJTzNh7PgyZnKaQzz * Add Golden Ticket detection usage example Demonstrates how to use the detection module to: - Collect events from domain controllers or CSV exports - Run all 6 detection rules for Golden Ticket indicators - Generate forensic reports in CSV, JSON, HTML formats - Score and prioritize findings Co-Authored-By: Claude Haiku 4.5 Claude-Session: https://claude.ai/code/session_01A7LqcMJTzNh7PgyZnKaQzz * Add comprehensive documentation for Golden Ticket detection module Includes: - Architecture overview and component descriptions - Usage examples and integration patterns - Detailed explanation of all 6 detection rules - Scoring methodology and interpretation guidelines - Known limitations and false positive mitigation - Output format examples (CSV, JSON, HTML) - Extension points for custom detections Co-Authored-By: Claude Haiku 4.5 Claude-Session: https://claude.ai/code/session_01A7LqcMJTzNh7PgyZnKaQzz * Add comprehensive single-file PowerShell Golden Ticket detector Monolithic PowerShell script consolidating all detection logic: - All 6 detection rules with multi-factor scoring - TGT (4768) ↔ TGS (4769) correlation engine - Privilege escalation chain tracking - Evidence tampering detection - DCSync-like replication access identification - krbtgt account modification tracking - Auto-DC discovery via Active Directory module - Multi-format output (CSV, JSON, HTML-ready) - Self-contained, no external dependencies Features: - Configurable analysis windows (hours, correlation hours) - Multi-DC support with cross-DC event correlation - Real-time event collection from Windows Security logs - Priority-based finding prioritization (CRITICAL/HIGH/MEDIUM/LOW) - Comprehensive reporting with raw event exports Usage: .\GoldenTicketDetector.ps1 -Hours 48 .\GoldenTicketDetector.ps1 -ComputerName DC1.corp.local -Hours 168 .\GoldenTicketDetector.ps1 -Hours 24 -ExcludeKdcOperational Co-Authored-By: Claude Haiku 4.5 Claude-Session: https://claude.ai/code/session_01A7LqcMJTzNh7PgyZnKaQzz * Fix PowerShell syntax error in color selection logic Replace inline if-elseif-else block in parameter with proper switch statement to avoid parentheses nesting issues in PowerShell. Fixes: Missing closing ')' in expression (line 840) Co-Authored-By: Claude Haiku 4.5 Claude-Session: https://claude.ai/code/session_01A7LqcMJTzNh7PgyZnKaQzz * Fix PowerShell hashtable syntax errors in Summary construction Replace quoted string keys with unquoted keys and pre-calculate count values to avoid hashtable syntax issues in PowerShell. Fixes: 'The assignment expression is not valid' errors on hashtable keys Changes: - Pre-calculate CRITICAL/HIGH/MEDIUM/LOW counts as variables - Use unquoted keys in hashtable literals (PowerShell best practice) - Update display section to use pre-calculated count variables Co-Authored-By: Claude Haiku 4.5 Claude-Session: https://claude.ai/code/session_01A7LqcMJTzNh7PgyZnKaQzz * Enable robust krbtgt metadata collection from local or remote AD Improvements: - Always attempt to collect krbtgt-current.json (not AD-dependent) - Try local AD first, then fall back to remote DC if available - Add Source field when collecting from remote DC - Graceful error handling for AD unavailability - Improve DC account discovery with error handling - Better status messages during collection This ensures krbtgt metadata is captured even when local AD module is not available, as long as the DC is reachable. Co-Authored-By: Claude Haiku 4.5 Claude-Session: https://claude.ai/code/session_01A7LqcMJTzNh7PgyZnKaQzz * Enhance privilege escalation detection in Golden Ticket detector Expand detection capabilities for privilege escalation chains: - Add 8 new sensitive privileges: SeIncreaseQuotaPrivilege, SeChangeNotifyPrivilege, SeServiceLogonPrivilege, SeSystemtimePrivilege, SeSystemEnvironmentPrivilege, SeProfileSingleProcessPrivilege, SeRemoteShutdownPrivilege, SeUndockPrivilege - Add ESCALATION_KEYWORDS array for pattern matching in event data - Expand SECURITY_EVENT_IDS from 15 to 25+ event types including: 4703 (Token Right Removed), 4704 (User Right Assigned), 4705 (User Right Removed), 4688 (Process Creation), 4720 (User Account Created), 4722 (User Account Enabled), 4732/4733 (Group Membership Changes), 4765 (SID History Added), 5140/5145 (Network Share Access) This enables comprehensive tracking of privilege escalation attack chains: DCSync → Forged TGT → Kerberos Logon → Privilege Escalation → Lateral Movement Co-Authored-By: Claude Haiku 4.5 Claude-Session: https://claude.ai/code/session_01A7LqcMJTzNh7PgyZnKaQzz * Add comprehensive audit policy checking and Rule 7 detection Enhance detection resilience when Kerberos auditing is disabled: 1. New functions: - Check-AuditPolicy: Queries audit policies on DC, detects if Kerberos auditing is enabled/disabled - Test-EventLogCoverage: Analyzes event log coverage and generates diagnostic warnings 2. New detection rule (Rule 7 - Audit Coverage Gap): - CRITICAL (score 8): Zero Security + KDC events despite analysis window - HIGH (score 6): Only Directory Service events, no Kerberos auth events - MEDIUM (score 3): Very low Security event volume (<5 events in hours) - Provides remediation: Enable with auditpol /set /category:"Kerberos..." 3. Enhanced output diagnostics: - Display event coverage at start of analysis - Show audit policy status with remediation guidance - Display event counts in analysis results - Flag when audit gaps prevent reliable detection Impact: Clarifies why detection may find no findings when audit policies are misconfigured, and provides actionable remediation steps. Enables analysis of environments with low/missing Kerberos event logging.

📋 Interpretation Guidelines

+
    +
  • No single event proves a Golden Ticket. 4769 without 4768 can be a legitimate correlation gap.
    • +
  • Look for multiple signals together: +
      +
    • Missing 4768 for a TGS request
      • +
    • Account doesn't exist in AD (deleted/compromised)
      • +
    • Weak encryption (RC4, DES)
      • +
    • Privilege escalation immediately after auth
      • +
    • krbtgt changes or DCSync-like access
      • +
    +
    • +
  • Context matters: Evaluate against your environment's baseline and normal audit patterns.
    • +
  • Check audit policies: Missing 4768s may indicate gaps in auditing rather than attacks.

+ Comprehensive Kerberos Golden Ticket Detection Engine + +.DESCRIPTION + Single-file forensic detection for Golden Ticket attacks and privilege escalation + in Active Directory environments through Windows Security event log analysis. + + Features: + - 6 multi-factor detection rules with scoring (1-10) + - TGT (4768) ↔ TGS (4769) correlation analysis + - Privilege escalation chain detection (4672 → 4624 → 4662) + - Evidence tampering detection (log clearing, audit policy changes) + - DCSync-like replication access identification + - krbtgt account modification tracking + - Multi-format output (CSV, JSON, HTML reports) + + Detection Signals: + - TGS without correlated TGT (forged ticket indicator) + - Missing accounts in AD (compromised credentials) + - Weak encryption (RC4, DES) + - Privilege escalation after suspicious auth + - Security log clearing and audit policy changes + - Non-DC replication right access + +.PARAMETER Hours + Analysis window in hours (default: 48) +

📋 Interpretation Guidelines

+
    +
  • No single event proves a Golden Ticket. 4769 without 4768 can be a legitimate correlation gap.
    • +
  • Look for multiple signals together: +
      +
    • Missing 4768 for a TGS request
      • +
    • Account doesn't exist in AD (deleted/compromised)
      • +
    • Weak encryption (RC4, DES)
      • +
    • Privilege escalation immediately after auth
      • +
    • krbtgt changes or DCSync-like access
      • +
    +
    • +
  • Context matters: Evaluate against your environment's baseline and normal audit patterns.
    • +
  • Check audit policies: Missing 4768s may indicate gaps in auditing rather than attacks.

-## Architecture - -``` -adpentest/detection/ -├── __init__.py # Module exports -├── events_parser.py # Parse Windows Security event XML -├── correlation_engine.py # Correlate 4768 → 4769 events -├── kerberos_detector.py # Main detection engine (6 rules) -├── privilege_escalation.py # Detect escalation chains -├── findings_reporter.py # Export CSV/JSON/HTML reports -└── README.md # This file -``` - -### Core Components - -#### 1. **SecurityEventParser** (`events_parser.py`) -Parses Windows Security event XML and normalizes fields: -- Extracts event data from XML `` elements -- Normalizes usernames (strips domain, SYSTEM accounts) -- Normalizes IP addresses (handles IPv4-mapped IPv6) -- Classifies encryption types (DES, RC4, AES) - -```python -from adpentest.detection import SecurityEventParser - -event = SecurityEventParser.parse_xml_event(xml_string, source_dc='DC1') -print(f"User: {event.target_user}, IP: {event.client_ip}") -``` - -#### 2. **KerberosCorrelationEngine** (`correlation_engine.py`) -Correlates TGT (4768) to TGS (4769) events: -- Indexes TGT events by user and IP for fast correlation -- Finds prior TGT within configurable window (default: 12 hours) -- Validates collection coverage (detects analysis window gaps) -- Calculates confidence scores for correlations - -```python -from adpentest.detection import KerberosCorrelationEngine - -correlator = KerberosCorrelationEngine(correlation_window_hours=12) -correlator.build_tgt_index(tgt_events) - -tgt = correlator.find_prior_tgt( - user='admin', - client_ip='192.168.1.100', - before_time=tgs_time -) -``` - -#### 3. **KerberosGoldenTicketDetector** (`kerberos_detector.py`) -Main detection engine implementing 6 scoring rules: - -| Rule | Description | Score | Evidence | -|------|-------------|-------|----------| -| 1 | TGS without correlated TGT | 3-9 | Forged ticket indicator | -| 2 | Kerberos logon without TGT | 3-7 | Missing auth step | -| 3 | Privilege escalation after suspicious auth | 6 | Escalation chain | -| 4 | krbtgt account modifications | 6 | Compromise indicator or remediation | -| 5 | Security log cleared / Audit policy changed | 4-7 | Evidence tampering | -| 6 | DCSync-like replication access | 7 | Non-DC using replication rights | - -Each rule uses multi-factor scoring to reduce false positives. - -#### 4. **PrivilegeEscalationDetector** (`privilege_escalation.py`) -Detects escalation chains and lateral movement: -- 4672 (Special Privileges) after suspicious Kerberos auth -- Token impersonation capabilities (SeImpersonate, SeAssignPrimaryToken) -- Admin share access (C$, ADMIN$, IPC$) by non-admin accounts -- Complete Golden Ticket exploitation chain: Forged TGS → Logon → Escalation - -#### 5. **FindingsReporter** (`findings_reporter.py`) -Exports findings in multiple formats: -- **CSV** — Importable to spreadsheets, databases -- **JSON** — Structured format for parsing -- **HTML** — Human-readable report with visualizations -- **By priority** — Separate files for CRITICAL/HIGH/MEDIUM/LOW -- **By category** — Grouped by finding type -- **By user** — Grouped by affected account - -## Usage - -### Basic Detection Flow - -```python -from adpentest.detection import ( - KerberosGoldenTicketDetector, - SecurityEventParser, - FindingsReporter, -) - -# Initialize detector -detector = KerberosGoldenTicketDetector( - hours=48, # Analyze last 48 hours - correlation_hours=12, # 12-hour correlation window -) - -# Parse and add events -for event_xml in collected_events: - event = SecurityEventParser.parse_xml_event(event_xml, source_dc='DC1') - if event: - detector.add_event(event) - -# Run analysis -findings = detector.analyze() - -# Generate reports -reporter = FindingsReporter(output_dir='./golden_ticket_audit') -reporter.export_findings_csv(findings) -reporter.export_findings_json(findings) -reporter.generate_html_report(detector, findings) -``` - -### Integration with PowerShell - -The module is designed to work with the included PowerShell forensics script: - -1. **Run PowerShell collection** on Domain Controllers: -```powershell -.\GoldenTicketAudit.ps1 -Hours 48 -OutputDirectory .\findings -``` - -2. **Python analysis** processes the exported CSV: -```bash -python3 examples/golden_ticket_detection.py --csv-file findings/security-events.csv -``` - -### Command-Line Example - -```bash -# Analyze exported events -python3 examples/golden_ticket_detection.py \ - --csv-file security-events.csv \ - --hours 48 \ - --correlation-hours 12 \ - --output ./findings \ - --verbose - -# Output files generated: -# - findings.csv (all findings) -# - findings.json (structured format) -# - summary.json (analysis metadata) -# - report.html (visual report) -# - findings_CRITICAL.csv (priority-filtered) -# - findings_user_admin.csv (user-filtered) -``` - -## Detection Rules Explained - -### Rule 1: TGS Without Correlated TGT - -**Pattern:** 4769 (TGS-REQ) with no prior 4768 (AS-REQ) within correlation window - -**Scoring:** -- +4 points if TGT missing AND collection coverage is complete -- +5 points if target user doesn't exist in AD -- +3 points if DES encryption used -- +1 point if RC4-HMAC encryption used -- +2 points if unexpected Kerberos realm/domain - -**Rationale:** -Normal Kerberos flow: TGT request (4768) → TGS request (4769) -Golden Ticket: Attacker forges TGT, skips 4768 → directly uses 4769 - -**False Positive Risks:** -- Cached TGTs (user cached credential from earlier) -- Log rollover (4768 fell off event log) -- Cross-DC activity (4768 on DC1, 4769 on DC2) -- Incomplete audit policy (Kerberos auditing not enabled) - -**Mitigation:** -- Correlate across all DCs -- Check collection window (flag events too close to start) -- Validate audit policy was enabled - -### Rule 2: Kerberos Logon Without TGT - -**Pattern:** 4624 (Logon Type 3=Network/Kerberos) without prior 4768 - -**Scoring:** -- +3 points for missing TGT with complete coverage -- +4 additional points if account doesn't exist in AD - -**Rationale:** -Successful Kerberos logon should have correlated TGT. If not, suggests: -- Forged ticket used (Golden Ticket) -- Cached credential (less suspicious) -- Multi-DC correlation gap - -### Rule 3: Privilege Escalation After Suspicious Kerberos - -**Pattern:** 4672 (Special Privileges) within 5 minutes of suspicious 4624 - -**Scoring:** 6 points (HIGH) - -**Sensitive Privileges Monitored:** -- SeSecurityPrivilege (Manage audit logs) -- SeDebugPrivilege (Debug programs) -- SeTcbPrivilege (Act as part of OS) -- SeLoadDriverPrivilege (Load drivers) -- SeImpersonatePrivilege (Impersonate clients) - -**Rationale:** -Complete attack chain: Forged TGT → Logon → Admin Rights → RCE - -### Rule 4: krbtgt Account Changes - -**Pattern:** 4724 (Password reset), 4738 (Account modified), 5136 (DS object modified) on krbtgt - -**Scoring:** 6 points (HIGH) - -**Context:** -- Legitimate: Security team resets krbtgt password after compromise (remediation) -- Suspicious: krbtgt password change by unexpected admin during breach - -### Rule 5: Evidence Tampering - -**Patterns:** -- 1102: Security audit log cleared -- 4719: Audit policy changed - -**Scoring:** -- 1102 (log cleared) = 7 points (CRITICAL) -- 4719 (policy changed) = 4 points (MEDIUM) - -**Rationale:** -Attackers often clear logs to hide Golden Ticket usage. Breaks 4768/4769 correlation. - -### Rule 6: DCSync-Like Replication Access - -**Pattern:** 4662 (Directory Service Object Operation) by non-DC account using replication GUIDs - -**Monitored GUIDs:** -- `1131f6aa-9c07-11d1-f79f-00c04fc2dcd2` — Replicating Directory Changes -- `1131f6ad-9c07-11d1-f79f-00c04fc2dcd2` — Replicating Directory Changes All -- `89e95b76-444d-4c62-991a-0facbeda640c` — In Filtered Set (RODC) - -**Scoring:** 7 points (CRITICAL) - -**Rationale:** -Non-DC accessing replication rights can lead to credential dumping (krbtgt theft). -This is prerequisite for Golden Ticket creation. - -## Output Formats - -### CSV Report - -``` -Time,DC,EventID,Category,Priority,Score,User,ClientIP,Service,Evidence,Notes -2024-09-16T14:32:15.123456,DC1,4769,Kerberos TGS Correlation Gap,HIGH,6,admin,192.168.1.100,krbtgt,4769 observed without correlated 4768,Prior4768=None; EType=0x17 -``` - -### JSON Report - -```json -[ - { - "time": "2024-09-16T14:32:15.123456", - "dc": "DC1", - "event_id": 4769, - "category": "Kerberos TGS Correlation Gap", - "priority": "HIGH", - "score": 6, - "user": "admin", - "client_ip": "192.168.1.100", - "service": "krbtgt", - "evidence": "4769 observed without correlated 4768 in configured window", - "notes": "Prior4768=None; EType=0x17", - "rule_id": 1 - } -] -``` - -### HTML Report - -Visual dashboard with: -- Summary statistics (CRITICAL/HIGH/MEDIUM/LOW counts) -- Interactive findings table -- Priority-based highlighting -- Interpretation guidelines - -## Limitations & False Positives - -### Known Limitations - -1. **Audit Policy Gaps** - - If Kerberos auditing is disabled, legitimate users show as missing 4768 - - Check `auditpol.exe /get /category:* /r` for audit configuration - -2. **Multi-DC Correlation** - - 4768 on DC1, 4769 on DC2 → appears as missing TGT - - Collect from ALL DCs in the domain - -3. **Log Rollover** - - Large domains with high volume may roll logs during collection window - - Older 4768 events fall off log before TGS is captured - -4. **Cached Credentials** - - Users with cached TGTs from previous logons show as missing TGT - - Context: Is the user normally online? Are they using cached creds? - -5. **Cross-Realm Kerberos** - - Forest trusts and cross-realm auth create different TGT patterns - - May show false positives without realm context - -### Reducing False Positives - -- ✅ Correlate across all DCs in the domain -- ✅ Check audit policy was enabled during analysis window -- ✅ Validate collection coverage (don't analyze events too close to window start) -- ✅ Use multi-factor scoring (combine multiple signals) -- ✅ Review context (is account active? Is IP normal?) -- ✅ Look for additional evidence (log clearing, escalation, DCSync access) - -## Extending the Module - -### Add Custom Detection Rule - -```python -from adpentest.detection import KerberosGoldenTicketDetector, Finding - -class CustomDetector(KerberosGoldenTicketDetector): - def _rule_7_custom_detection(self, events): - """Your custom detection logic.""" - for event in events: - if your_condition: - self._add_finding( - time=event.time_created, - dc=event.source_dc, - event_id=event.event_id, - category='Custom Detection', - score=5, - user=event.target_user, - client_ip=event.client_ip, - service='', - evidence='Your evidence', - notes='Your notes', - rule_id=7, - ) -``` - -### Add AD Lookup - -Implement `_check_account_exists()` to query AD for user account status: - -```python -from ldap3 import Server, Connection - -def check_account_state(username, domain): - server = Server(f'ldap://{domain}') - with Connection(server, auto_bind=True) as conn: - filter_str = f'(sAMAccountName={username})' - result = conn.search('dc=...', filter_str) - return 'Exists' if result else 'Missing' -``` - -## References - -- **Event IDs**: Microsoft 4768/4769/4624/4672/1102/4719/4662 documentation -- **Kerberos Encryption Types**: RFC 3961 (Kerberos Encryption Types) -- **Golden Ticket Attacks**: MITRE ATT&CK T1528, TA0005 (Privilege Escalation) -- **Detection Techniques**: Splunk Golden Ticket Detection Search - -## Related Tools - -- **PowerShell Script**: `GoldenTicketAudit.ps1` (forensic collection) -- **Bloodhound**: Red Teaming tool showing AD relationships -- **Mimikatz**: Golden Ticket generation (for authorized testing only) -- **Rubeus**: Kerberoasting and ticket manipulation - -## Support - -For issues, questions, or improvements: -1.

📋 Interpretation Guidelines

-
    -
  • No single event proves a Golden Ticket. 4769 without 4768 can be a legitimate correlation gap.
    • -
  • Look for multiple signals together: -
      -
    • Missing 4768 for a TGS request
      • -
    • Account doesn't exist in AD (deleted/compromised)
      • -
    • Weak encryption (RC4, DES)
      • -
    • Privilege escalation immediately after auth
      • -
    • krbtgt changes or DCSync-like access
      • -
    -
    • -
  • Context matters: Evaluate against your environment's baseline and normal audit patterns.
    • -
  • Check audit policies: Missing 4768s may indicate gaps in auditing rather than attacks.
