description

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 attacks, ADCS abuse (ESC1-ESC15), and modern MDI/Defender for Identity evasion. Use when assessing on-prem AD, hybrid AD/Entra ID environments, or ADCS deployments.

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

# 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)

# Domain enumeration without binaries
$d = [System.DirectoryServices.ActiveDirectory.Domain]::GetCurrentDomain()
Get-DomainUser -SPN | Select samaccountname,serviceprincipalname
Get-DomainComputer -Unconstrained
Get-DomainGPO | ?{$_.gpcmachineextensionnames -match "Restricted Groups"}
Get-DomainObjectAcl -Identity 'Domain Admins' -ResolveGUIDs |
  ?{$_.ActiveDirectoryRights -match 'WriteDacl|GenericAll|WriteOwner'}
