Intelligence Summary
The Head Mare hacktivist group has been compromising TrueConf video conferencing servers. Attackers use unpatched vulnerabilities on exposed servers to replace legitimate client installers with trojanized versions. The modified installers are designed to install backdoors on infected systems. This turns a server-side compromise into a supply-chain style distribution of malicious software to users. Organizations running affected TrueConf deployments should patch servers and restrict installer delivery until their systems are verified clean.
Recommended Action
Prioritize immediate review, validate exposure, and patch or mitigate affected systems.
