Overview
- An internal assessment says a hacker used Citrix remote access with compromised credentials to persist on FEMA networks from June 22 to August 5 and exfiltrated data from Region 6 servers.
- The stolen information concerns employees of FEMA and U.S. Customs and Border Protection, and the attacker’s identity remains unknown.
- On July 14 the intruder installed virtual networking software and obtained Microsoft Active Directory access to enable data extraction.
- FEMA cut off Region 6 Citrix access on July 16, enforced multifactor authentication, ordered agencywide password changes on August 18, and adjusted Zscaler policies with site blocks on September 5.
- Homeland Security Secretary Kristi Noem dismissed about two dozen FEMA IT officials and reorganized leadership after the breach, while investigators review a suspected Citrix vulnerability dubbed CitrixBleed 2.0.
