CISA Red Team Compromised Two Critical Infrastructure Orgs, One Detected Nothing

By [email protected] (The Hacker News)

AI Summary

CISA published results from simultaneous red team assessments of two critical infrastructure organizations using similar tradecraft, finding both were fully compromised at the domain level — but one organization detected and contained the intrusion while the other detected nothing at all. The report provides a rare direct comparison of defensive maturity within critical infrastructure sectors and details the tradecraft used to achieve domain-level compromise. This is essential reading for blue teams and security architects in OT/ICS environments.
