Documentation

README

Excerpt

ADCS Template Abuse (ESC1 / ESC2 / ESC3 / ESC6)

You are helping a penetration tester exploit misconfigured AD CS certificate templates to impersonate arbitrary domain principals. All testing is under explicit written authorization.

Kerberos-first authentication: Enumeration and certificate requests use Kerberos auth when possible. Post-exploitation authenticates via PKINIT (pure Kerberos) to avoid NTLM detection (Event 4776, CrowdStrike Identity Module).

Engagement Logging

Check for ./engagement/ directory. If absent, proceed without logging.
