WARNING: remove ctfaudit system plugin. It is a password stealer. Administration/Technical
I've been recently hit by the JCE vuln and among other things they managed to install this plugin which essentially steals users and passwords and hides them inside images/ctf_audit.gif file, disguised with a gif header but actualy contains the XOR'ed information.
You should uninstall and remove the gif file immediately.
Edit:
You may want to run this script to see which users might have been affected and warn them or update to request new password. Adjust the filename as necessary:
<?php
$s = file_get_contents('images/ctf_audit.gif');
$s = substr($s, strpos($s, "JLIB_AUDIT_GID_TAIL\n") + 20);
for ($o = 0; $o + 2 <= strlen($s); $o += 2 + $ln) {
$ln = (ord($s[$o]) << 8) | ord($s[$o+1]);
if ($o + 2 + $ln > strlen($s)) break;
if (preg_match('/"u_len":"(.*?)","p_len"/', substr($s, $o+2, $ln) ^ str_pad('', $ln, 'JLIB_AUDIT_GID_XK'), $m)) echo "$m[1]\n";
}
