SolvedHow?

Basically, there's an exploit going around for GMod, and my server's been effected.

The 'hackers' add themselves to SA groups, and they can do anything they want.
I found an exploit called 'BridgeHack', and upon going through it, it tells me that my ULX Extended is exploitable.

Now, how do I make this unexploitable, and how do I go about making it so they won't be able to do this anymore?

The way they do it is by 2 files.
They load up a 2 player single player game, type in 'sv_allowcslua 1' then 'lua_openscript_cl bypass.lua' and then they join an online server, that's how they're executing different shit.

I've acquired Cake! Anti-Cheat, legitimately, and they're still doing it, I have no fucking idea what to do any more, so I thought I'd ask MPGH to help.

I've been banned on 2 servers, yet my server is effected?
I'm so confused, and I want to know how to fix this..


Any idea?
Thanks in advance.

Cake! won't even fucking ban me for console variable manipulation, I have no fucking idea what's going on.

It appears there exploitable addons on your server, which means that people have found ways of tricking it into doing things.
There are a couple of Cake Anti-Cheat Bypasses floating about.. So try changing to a custom made one or somehow blacklist the bypass. On the subject of console manipulation are you using an alt account or one you have admin on? You may be whitelisted (So you don't get banned) or your settings aren't configured properly.
The hack they are using (Bridge-hack) is really just a massive copy and paste menu that gets "Leaked" constantly, half the exploits on it don't work anymore.

TL;DR
As long as you replace / fix any exploitable addons, you should be fine.

Private message me your server's IP. If it's a LUA exploit I'll look for it
