Active Directory attack methodology for internal network red team engagements. Covers reconnaissance (BloodHound, PowerView, ADExplorer), credential abuse (Kerberoasting, ASREProasting, NTLM relay, LLMNR/NBT-NS poisoning), privilege escalation (ACL abuse, GPO abuse, unconstrained/constrained delegation), lateral movement (Pass-the-Hash, Pass-the-Ticket, Overpass-the-Hash, WMI/WinRM/PsExec), persistence (Golden/Silver/Diamond Tickets, DCSync, DCShadow, AdminSDHolder, Skeleton Key), forest trust…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Active Directory — Offensive Testing Methodology ## Quick Workflow 1. Recon AD structure offline (BloodHound, ADExplorer snapshot) — minimize live queries 2. Harvest creds via poisoning, Kerberoasting, ASREProast, or LSASS where allowed 3. Map attack paths to Domain Admin / Enterprise Admin / Tier 0 4. Execute path with lowest detection cost, validate at each hop 5. Establish persistence and document every action with timestamps --- ## Reconnaissance ### BloodHound Collection ```powershell # SharpHound (CSharp collector) — most stealthy with throttling SharpHound.exe -c All,GPOLocalGroup --Throttle 1000 --Jitter 30 --ZipFileName recon.zip # Stealth collection (DC-only, avoids workstation noise) SharpHound.exe -c DCOnly --Stealth # Bloodhound.py from Linux (no Windows host needed) bloodhound-python -d corp.local -u user -p pass -ns 10.0.0.1 -c All ``` ### PowerView (No Tool Drop) ```powershell # Domain enumeration without binaries $d = [System.DirectoryServices.ActiveDirectory.Domain]::GetCurrentDomain() Get-DomainUser -SPN | Select samaccountname,serviceprincipalname Get-DomainComputer -Unconstrained …

How to install
mdr add miosa-osa/osa/offensive-active-directory@sha256:7bf954571829aaccThe line at the top of this page pins the label git:20260913.e13b6b8, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
