What If there was a Supply Chain Compromise of an IDP like Okta? by Luke Richards

This guidance document uses the recent Okta-related supply chain incident as a scenario to outline how security teams should respond to an Identity Provider compromise: establish scope and timeframe, inventory IdP touchpoints, review and roll back suspicious changes, reset credentials and rotate keys, revoke excessive third‑party access, and strengthen monitoring and incident response playbooks. It also describes signs of compromised accounts and points to key Windows AD log events (4624 logon types 10 and 3, and 4768) to identify anomalous behavior aligned with attacker objectives.
