PhantomCore and PhantomGraph backdoors delivered via an unpatched TrueConf server 0 The Head Mare APT group exploited unpatched vulnerabilities in TrueConf video conferencing servers to deploy PhantomCore and PhantomGraph backdoors. Attackers gained unauthorized access via port 4307/TCP, executing arbitrary code with SYSTEM privileges. They replaced legitimate client installers with infected versions and deployed a web shell for persistence. PhantomGraph used Microsoft OneDrive for command-and-control. Affected TrueConf versions include 5.3.x through 5.3.9, 5.4.x through 5.4.9, and 5.5.x through 5.5.5. Multiple Russian organizations across various industries were targeted.
