CISA Releases Insights from Red Team Assessment of a U.S. Critical Infrastructure Sector Organization

Today, CISA released Enhancing Cyber Resilience: Insights from CISA Red Team Assessment of a U.S. Critical Infrastructure Sector Organization in coordination with the assessed organization. This cybersecurity advisory details lessons learned and key findings from an assessment, including the Red Team’s tactics, techniques, and procedures (TTPs) and associated network defense activity.

This advisory provides comprehensive technical details of the Red Team’s cyber threat activity, including their attack path to compromise a domain controller and human machine interface (HMI), which serves as a dashboard for operational technology (OT).

CISA encourages all critical infrastructure organizations, network defenders, and software manufacturers to review and implement the recommendations and practices to mitigate the threat posed by malicious cyber actors and to improve their cybersecurity posture.
