Threat Risk: High
Victim: Critical Infrastructure Organizations
Incident: Full domain-level compromise of two critical infrastructure entities during a CISA red team assessment.
Impact: Unauthorized access to sensitive business systems, cloud resources, and privileged security communications.
Attacker: CISA Red Team
Analysis: CISA’s red team achieved full domain compromise in two organizations by leveraging misconfigured AD CS templates and default credentials. The failure of one organization to detect any activity highlights the dangers of alert fatigue and siloed security operations. This exercise underscores that technical controls are insufficient without rigorous escalation procedures and visibility.
Recommendations: Audit AD CS certificate templates to prevent ESC1 abuse and domain takeover; Rotate static cloud access keys and implement strict token revocation policies; Streamline SOC workflows to reduce alert fatigue and improve cross-tool visibility
