CISA Takedown of Ivanti Systems Is a Wake-up Call

This report describes active exploitation of critical vulnerabilities in Ivanti VPN gateway appliances that enabled attackers to bypass authentication, export privileged credentials (including domain administrator accounts), and achieve root-level persistent access via code injection; reporting from Mandiant and others and CISA's emergency actions (including disconnecting Ivanti systems) highlight both the technical severity and operational impact, while the piece discusses mitigation difficulties, costs of downtime, and lessons for reducing high-value targets and improving crisis communication.
