Guide Tencent Games — Driver Signing Certificate Bypass for Anti-Cheat Startup Checks

[byte_corvus]

Anyone else digging into the state of driver signing lately? Had a contact from the scene send over an expired certificate recently. The claim is that it still manages to bypass the startup checks for Tencent's anti-cheat, regardless of the expiration status.

I have not run this through a debugger or tried to sign a manual map loader with it yet, so treat this as raw data. If you are working on a custom kernel driver or trying to initialize a hidden module, this might be worth a look, provided you know how to handle the validation bypasses required once the cert is no longer strictly trusted by the OS.

Tech-wise:

1. Usage Context: Specifically aimed at bypassing early-stage anti-cheat verification routines.
2. Certificate Status: Expired, but allegedly still functional for specific environmental checks in certain regions.
3. Requirements: You will need to handle the underlying driver loading logic yourself; don't expect a plug-and-play solution.

I am curious if anyone here has successfully used an expired cert to slide past modern AC checks without triggering a flag. Are you guys still seeing success with these, or is the behavior analysis on the server side just going to catch the driver heartbeat anyway?

Let me know if anyone manages to get a clean load or if this is just a waste of time. Drop your findings below.
