From the source SKILL.md

AD CS is the single richest privilege-escalation surface in modern AD. A misconfigured template or CA lets a low-privileged user obtain a certificate that authenticates as a Domain Admin. This skill uses Certipy (the ly4k project) throughout. You drive it by hand.

certipy find -u [email protected] -p 'Password123' -dc-ip 10.0.0.10 -vulnerable -stdout
