Hacked & Secured: Pentest Exploits & Mitigations

Ep. 13 – nOAuth Account Misbinding & Assumed-Breach to Domain Admin (Season Finale)

Amin Malekpour Season 1 Episode 13

One misbound identity. One exposed internal path. Two routes to total compromise.

In this season finale of Hacked & Secured: Pentest Exploits & Mitigations, we break down two real-world findings that show how small trust assumptions can unravel entire systems:

  • nOAuth (SSO account misbinding) — Multi-tenant SSO auto-linked accounts by email instead of a stable subject/issuer identifier. With a crafted identity on a controlled domain, an attacker could land a valid session as another user. 
  • From wall socket to Domain Admin — No NAC on the switch enabled quiet network access, followed by username harvesting and a light password spray to a low-priv account. From there: AD enumeration, weak service credentials, and abuse of certificate services to escalate to Domain Admin.

What you’ll learn: how identity claims should be bound in modern SSO, how to harden join and mapping flows, and a practical checklist to shut down common internal escalation paths (NAC, credential hygiene, service principals, AD CS, and monitoring).
