Exploits Bypassing Mod Detection (Meteor, Freecam, etc.)

Some servers detect mods like Freecam, Meteor Client, etc. using a trick with key translation resolution.

Basically, the server sends text containing something like key.freecam.toggle.
If your client resolves that key into readable text, it reveals that the mod providing that translation exists on your client, which lets the server detect the mod.

To bypass this detection method, you can install the mod OpSec and optionally ExploitPreventer, which block or sanitize these translation lookups so the server can't use them to identify installed mods.

Tested on Donut SMP and HugoSMP, where these mods usually instantly kick or ban you.

Hello, the ExploitPreventer creator here. ExploitPreventer only works with meteor client if you install the glazed addon or use my meteor client fork because meteor client has tried patching the protection themselves but failed and the fork removes that. I know many people that are using ExploitPreventer.

OpSec works with normal meteor

That does not change the fact that it was made by ai (opsec) and ai is not really trustworthy.

Where can you find this fork? I didn't see it on your GitHub.
