adPEAS

Comprehensive Active Directory security assessment — zero dependencies, single file, ready to go.

adPEAS is a PowerShell-based security assessment tool that identifies misconfigurations, vulnerabilities, and privilege escalation paths in Active Directory environments. It is designed for penetration testers, security auditors, and red teams who need a reliable, self-contained tool that works on any Windows system — no RSAT, no ActiveDirectory module, no third-party dependencies.

adPEAS v2 is a complete rewrite of adPEAS v1. It replaces the legacy DirectoryEntry/DirectorySearcher approach with a unified System.DirectoryServices.Protocols.LdapConnection architecture and adds native Kerberos authentication, advanced reporting, and offensive operations — all in pure PowerShell.

• Native Kerberos stack — AS-REQ/AS-REP, TGS-REQ/TGS-REP, Pass-the-Ticket, PKINIT, all in pure PowerShell
• Multiple auth methods — Password, NT-Hash (OPtH), AES keys (PtK), Certificates (PKINIT & Pass-the-Cert/Schannel), Windows integrated
• 40+ security checks across 9 categories with severity scoring
• Interactive HTML reports with search, filtering, risk scores, and tooltips
• JSON export for offline report conversion, incremental scanning, and scan comparison
• BloodHound CE collector — built-in data collection for attack path analysis
• Offensive operations — Kerberoasting, AS-REP Roasting, Golden/Silver/Diamond Tickets, RBCD abuse, Shadow Credentials, and more
• Session-based workflow — connect once, run multiple checks interactively
• Tab-completion — autocomplete AD object names for interactive exploration

No ActiveDirectory module, RSAT, or external PowerShell modules required.

All four versions are functionally identical. Choose based on your deployment scenario.

# Clone the repository
git clone https://github.com/61106960/adPEAS.git
cd adPEAS

The main branch contains only source files (src/). Release builds are attached to each GitHub Release. If you want to build from the latest source, use the included build script:

git clone https://github.com/61106960/adPEAS.git
cd adPEAS
.\Build-Release.ps1

This produces all four variants (adPEAS.ps1, adPEAS_min.ps1, adPEAS_ultra.ps1, adPEAS_obf.ps1) in the repository root. Requires Windows PowerShell 5.1 and no additional dependencies.
