UNC6595 is a China-nexus cyber-espionage threat cluster observed exploiting the critical React Server Components vulnerability CVE-2025-55182, also known as React2Shell, for initial access. The group has been associated with deployment of ANGRYREBEL.LINUX, also referred to as Noodle RAT, a Linux remote access trojan used to establish post-compromise control on targeted systems. Reported activity indicates a focus on infrastructure hosted on international virtual private servers, consistent with targeting of internet-facing server environments rather than end-user systems. UNC6595 has been identified among multiple Chinese state-linked groups that rapidly operationalized public exploitation of React2Shell. Its observed tradecraft includes exploitation of exposed web application infrastructure for initial access, followed by malware deployment for persistent remote administration and follow-on post-exploitation activity. The use of a Linux RAT indicates capability to operate in server and cloud-hosted environments. UNC6595 is part of a broader set of China-linked intrusion clusters observed using the same vulnerability for espionage-oriented access and foothold establishment.
