DACL Attacks: Abusing WriteOwner for Privilege Escalation

Welcome back to the DACL Attacks series! In this episode, we dive deep into Active Directory Access Control Lists to explore how a seemingly harmless misconfiguration—the WriteOwner permission—can be completely weaponized for lateral movement and privilege escalation. First, we break down the basics of Access Control Entries (ACEs) and the default "implicit deny" rule in Active Directory. Then, we walk through a hands-on scenario where our compromised user, fcastle, abuses WriteOwner permissions over their admin account (fcastle_adm) to grant themselves GenericAll access and force a password reset. Whether you are a penetration tester or a system administrator looking to secure your AD environment, understanding how to enumerate and defend against these ACL misconfigurations is critical. 🔗 Resources & Tools Mentioned: TheHackerRecipes - https://www.thehacker.recipes/ad/move... 🚨 DISCLAIMER: This video is strictly for educational purposes and ethical hacking.
