AI Summary
Cisco Talos identified three threat clusters exploiting two recently patched vulnerabilities in Cisco Secure Firewall Management Center (FMC): CVE-2026-20079 (authentication bypass, CVSS 10.0) and CVE-2026-20316 (static credentials, CVSS 5.3). UAT-11988, linked to Qilin ransomware affiliates, used static credentials to deploy ransomware after reconnaissance and lateral movement. UAT-11823, attributed to the Sandworm APT group, exploited both flaws to deploy a Cyclops Blink variant for persistent access and credential theft. UAT-12197 deployed a JSP web shell and malicious JAR file to steal credentials. Cisco confirmed exploitation of both vulnerabilities in active attacks.
