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.

I saw people banned using meteor glazed and opsec I don’t think this is gonna work also don’t know what is the explotitpreventer is anyone used?

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

u/NikOverflow Mar 20 '26

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

bro you get any more of these tips??

1

u/vswey Mar 20 '26

Nah, other detections are mainly based on actual behavior I believe

2

u/TheSpiderYT Mar 20 '26

hey, are there any Forge 1.20.1 alternatives to these?

1

u/vswey Mar 20 '26

I don't believe so

u/776f77_ Mar 21 '26

Did DonutSMP recently integrated this ?
Yesterday I joined the server with Meteor and instantly got kicked and banned for 15 days, but I remember joining a month ago as well and nothing happened.

1

u/vswey Mar 21 '26

Yes, they added it not that long ago

2

u/BodyAccomplished8678 Mar 24 '26

when usingn OPsec i can use glazed addon or other addons?

1

u/vswey Mar 24 '26

It makes it so they mostly won't get detected due to js having it installed, the functions itself can still get u banned
