BackDoor Detector

Is they such thing as a backdoor detector so you can see where the backdoors are and remove them or even better one what prevents them?

First of all try to do a traffic analyze, record all traffic between your client/server and network interfce, see if there are any suspicious IP addresses involved. That would be one of the easiest ways of doing it

Are you talking about a backdoor on a server on your personal computer?

In my gmod server I usually use nomalua, but it takes a lot of your time to find, search and remove a backdoor with it

Use nomalua and do a deep search for RunString's, SteamID's, and encrypted text. Could be in from a workshop addon or leaked script.
I don't recommend it, but if you're too lazy, slap SNTE on as a band-aid.

omg... download a fucking visual editor, open server folder and search for following:

runstring
fetch
connmand
superadmin
ulx adduser
http.post "http.post only post to target, solely is it harmless, however might be lead to simple conmand backdoors"

DONT FUCKING RUN A GMODSERVER IF YOU CANT BASIC SHIT

if you want there is a good backdoor detector named "nomalua" it detects nearly every backdoors

Does anyone have like a download link to this nomalua
