There’s this weird backdoor that keeps placing houses from LiveTopia in my game.

I don’t know which script is causing it and it has been bugging me for a long time now.
Any tips on how I could find the cause of this?

In studio, press CTRL + SHIFT + F, search for getfenv(), require, and eriuqer. These, I believe are the most popular backdoor implementations, if it’s not there, there are different keywords you can search. Let me know if you find anything with the following.

Actually, there’s no need to search for that because you need to pair it with getfenv. If you wanted to cover every string combination, you would also need to cover cases like this:

local a = "e" local b =  "q" local c =  "r" local e = c..a..b .. "u"
local a = "i" local b = c local e = e..a..b.."e"
getfenv()[a](12345)

getfenv()[("\82\69\113").lower()..string.char(117)..("er").reverse()](12345)

It’s easier to just tackle require and getfenv.

i recommend checking for loadstring aswell (require and getfenv are most likely to be the case tho)
