TrueConf Client Update Integrity Bypass — Remote Code Execution via Tampered Updates

Imagine you get a software update notification from your video conferencing app, TrueConf. You click 'update' thinking it's legit — but the app never actually checks if the update is real or fake. An attacker sitting on your network (or who compromised the update server) can slip in malicious code disguised as an update. Your computer installs it without question. This was used as a zero-day in real attacks against Southeast Asian government networks in an operation called 'TrueChaos.' CISA added it to their must-patch list.
