Anticheat Update Tracking

Very nice walk-through on the reverse engineering process.

Also, they linked this post that made my jaw drop: https://www.unknowncheats.me/forum/anti-cheat-bypass/667333-...

Apparantly BattleEye anti-cheat had an exploit where hackers could permanently ban any player they wanted. BattleEye allowed anybody to log in as a "game server" so hackers simply booted up a fake server, told BattleEye that "player X has logged in and is doing a bunch of suspicious stuff" and then player X's account was no more...

I'm sorry, why do we trust these guys again?

This BattleEye exploit demonstrates a classic failure of trust boundary definition - they effectively created a system where client attestation was accepted without proper authentication or verification.
