CISA released a cybersecurity advisory sharing lessons learned from responding to a breach at a U.S. federal agency, highlighting the importance of prompt patching, effective incident response planning, and log management. The attack involved exploitation of CVE-2024-36401 in GeoServer, with threat actors gaining initial access, establishing persistence, and moving laterally within the network over three weeks before detection. CISA emphasizes immediate patching of known vulnerabilities, testing incident response plans, and implementing comprehensive logging to improve security posture and prevent similar incidents.

The Cybersecurity and Infrastructure Security Agency (CISA) is urging the UEFI community to enhance cybersecurity measures for Unified Extensible Firmware Interface (UEFI), a critical software standard in modern computing. UEFI serves as an interface between hardware and operating systems, but attackers have exploited UEFI implementation flaws to gain persistence and maintain access to compromised systems. The community needs to implement public key infrastructure (PKI) practices for patch distribution and improve secure by design and Product Security Incident Response Team (PSIRT) maturity. System owners should be able to audit and update UEFI components, operational teams should collect and respond to UEFI-related event logs, UEFI component developers should adopt secure development practices, and the UEFI vendor community should ensure uninterrupted and reliable update capabilities.
