    wpmu 1.2.5.a
    hosted on siteground.com

    Such already was and repeats again: in all files php and my own html in a folder /public_html the harmful code is added! Php warning on main page and not have access to admin interface.

    Sample wp-rss.php:

    <?php

    if (empty($wp)) {
    require_once('wp-config.php');
    wp('feed=rss');
    }

    require (ABSPATH . WPINC . '/feed-rss.php');

    Added modlook in a hopefully attempt to get rid of all that.

    wpmu 1.2.5.a

    That's probably your problem right there. 1.3 has been out for quite sometime and fixed some security problems. Keeping an eye on versions is usually a good thing.

    theapparatus, thanks.
    I thought to spend upgrade at once after version 1.3 release. But there is no support XMLRPC and it is necessary for me. Though for the sake of safety it is possible to endow functionality.

    There is XMLRPC support in 1.3.

    donncha said: "The XMLRPC disable code is safe, I'll be releasing it as a standalone WordPress MU plugin in a few days."
    Where is that plugin?

    I installed WPMU 1.3 and while XMLRPC is disabled by default, it was possible to enable it on a 'per blog' basis. I couldn't find an option to enable it site-wide but i didnt look too much. However, the functionality is definitely there.

    Means upgrade time has come.
    But it is interesting as this hacker's code is added?

    XMLRPC is enabled in 1.3. The disabling code was taken out before the final release. I keep meaning to release that plugin but I never get around to it..

    Unfortunately, it's probably because you were using an old version of WPMU that you got hacked :(
