Cannot locate an instance that is being logged in the developer console

I know how the Explorer works. But how I can spot if it isn’t something that should be there?

Tbh Idk, but just use my tip it will speed u up

Thanks anyway, I’ll try my best.

Great news! Roblox recently made an update where instances of “require” are actually logged in the output. This let me find the backdoor, including all the assets that it redirects to. Turns out that the backdoor was located in a model that was spawnable in the game. Not sure why I didn’t think of that.

Also, here are the asset IDs and the error message of the last asset (I think it has the IP address of the user/server that is responsible for this. If anyone can get these assets taken down or even get that IP address investigated/taken down, I think a lot of people will be saved from this backdoor.

More information: I just checked the script, and it’s the “RoSync” loader. I think a lot of the RoSync backdoors can be located this way, and hopefully it can be reported to Roblox for them to do something about it.
