The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/), and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html). +## [1.2.4] - 2026-09-09 + +### Fixed +- **`parallel_pentest_attempt` `technique="all"`**: the documented "all" mode + was unimplemented, so every host failed with `Unknown technique: all` + (0% success). It now runs all five techniques (smb-null-session, + ldap-anonymous, rpc-probe, smtp-vrfy, kerberos-probe) per host and + aggregates the result, exposing each technique under + `details.per_technique`. +- **Live-host filtering**: `is_usable_host` now also rejects link-local / + APIPA (169.254.0.0/16), reserved addresses (incl. 255.255.255.255), and the + network/broadcast addresses of a /24 (last octet 0 or 255), so recon and + pentest passes no longer treat broadcast/APIPA noise as live hosts. + +## [1.2.3] - 2026-09-09 + +### Added +- **Nmap-driven de novo vulnerability discovery** (`adpentest/nmap_vuln_discovery.py`): + a heuristic engine that derives *candidate* weaknesses from an nmap `-sV` + + `default,safe,vuln` NSE scan (plus the bundled AdPentestAI NSE scripts), + rather than a fixed CVE list — so it surfaces novel/uncatalogued exposures. + Detectors cover exposed management planes, cleartext services, anonymous / + null-session access, outdated builds, unusual datastore/web topologies, and + NSE vuln-script hits referencing CVE ids not in the framework catalog. The + engine is read-only and labels every finding a hypothesis requiring + validation, not a confirmed vulnerability. Run via + `python -m adpentest.nmap_vuln_discovery `. + +### Changed +- **Linux-native SMB enumeration**: `enum_smb` now uses impacket (pure Python, + null/guest session) as its primary, cross-platform method, so share + discovery works off-Windows without PowerShell. The PowerShell/WinRM methods + are only attempted when a PowerShell binary is actually present, and now use + `pwsh` when available instead of hard-coding `powershell.exe`. +- **NSE scripts injected into every nmap run**: `nmap_scan` (and the SMB + signing probe) now automatically append the bundled AdPentestAI NSE scripts + (`ad-cve-6130`, `cve-de-novo`) by absolute path, so they run on every scan + without needing write access to nmap's scriptdir or `--script-updatedb`. +- **Cross-platform auto-install of missing tools**: `auto_install_tool` now + installs missing binaries on Linux via whichever package manager is present + (apt/dnf/yum/pacman/zypper) instead of assuming apt, with per-manager package + names (e.g. `samba-client` on dnf/yum/zypper) and a pip fallback; Windows + continues to use winget then pip. Auto-install therefore works on both + Windows and non-Debian Linux, not just Debian/Ubuntu. + +## [1.2.2] - 2026-09-08 + +### Added +- **Native Nmap NSE scripts** (`nse/`): CVE checks that run inside Nmap's own + scan pass using its `ldap`/`http`/`shortport`/`stdnse` libraries instead of + shelling out. + - `ad-cve-6130.nse` — host script detecting AD Domain Controllers and scoring + CVE-6130 exposure from open AD ports plus an anonymous LDAP RootDSE read; + lists related critical AD CVEs (ZeroLogon, sAMAccountName spoofing, + PrintNightmare, LDAP-signing) whose network preconditions are met. + - `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. + - `install-nse.sh` — auto-installs nmap (apt/dnf/yum/pacman/brew/winget), + embeds the `.nse` files into nmap's scriptdir, and runs `--script-updatedb`. + - `adpentest/nse_integration.py` — `NSEIntegration` class to install nmap, + embed the scripts, and drive them via `nmap --script` from the framework. +- **CVE-6130 / AD vulnerability assessment suite**: `adpentest/ad_vuln_detector.py`, + `adpentest/ad_6130_scanner.lua`, `examples/ad_cve_6130_check.py`, and + `AD_CVE_6130_ASSESSMENT.md` documenting detection, scoring, and remediation + for CVE-6130 and related critical AD CVEs. +- **Lua nmap CVE checker**: `adpentest/nmap_cve_checker.lua` plus + `adpentest/lua_nmap_integration.py` for cross-platform nmap auto-installation + and de novo CVE detection, with a test suite and runnable examples. + +### Fixed +- **LDAP enumeration crash**: `enum_ldap`, `enum_policy`, and `SPNEnumerator` + passed an unsupported `timeout=` kwarg to `ldap3.Server()`, raising + `Server.__init__() got an unexpected keyword argument 'timeout'` on every + run. Corrected to `connect_timeout=`. +- **Tarpit / accept-all false positives**: `check_ports` now probes control + ports that should be closed (1, 4, 7, 8389, 10389, 33389, 53389); when a + host answers "open" on ≥3 of them it is treated as a tarpit and its + port-based findings are suppressed, preventing bogus "all AD ports open" + detections and the port-presence CVE false positives that follow. +- Synchronized the package version across `pyproject.toml`, `adpentest/__init__.py`, + and `adpentest/core.py` (core was lagging at 1.1.5). + ## [1.0.2] - 2026-09-02 ### Major Features diff --git a/DEPLOY_ON_WINDOWS.md b/DEPLOY_ON_WINDOWS.md new file mode 100644 index 0000000..f608775 --- /dev/null +++ b/DEPLOY_ON_WINDOWS.md @@ -0,0 +1,190 @@ +# Deploying Golden Ticket Detector on Windows + +## Quick Start - Run TestAll on 172.16.199.158 + +### On Windows Machine with Admin Access + +```powershell +# PowerShell (as Administrator) + +# 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.

📋 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) +
