Sucuri SiteCheck – Web Malware Distribution – January 2012

As many know, we have been offering our free website malware scanner – Sucuri SiteCheck, since early in 2011. In our commitment to continue to give back to the community, we want to share some statistics. We’d like to share the distribution of infections based on the number of sites that are being scanned using Sucuri SiteCheck.

In January, we scanned a couple 100 thousand sites. From those we were able to better understand the distribution of malware.

Top linked sites – What webmasters are linking to

We scan hundreds of thousands of sites daily here at Sucuri and while analyzing some of the data we got interested on what sites are getting the “link love” more often.

By link love, I mean what “do follow” links most webmasters have in their sites? After extracting the data from the last 500k scans we did, those were the top:

  1. 6.9% – www.facebook.com
  2. 6.4% – twitter.com
  3. 2.8% – wordpress.org
  4. 2.6% – youtube.com
  5. 1.9% – feeds.feedburner.com
  6. 1.2% – www.linkedin.com
  7. 1.2% – www.google.com
  8. 1.1% – validator.w3.org
  9. 1.1% – wwww.adobe.com
  10. 0.9% – www.addthis.com

So it means that 6.9% of the sites had a link to facebook, 6.4% to twitter, etc. I was actually surprised to see validator.w3.org ranked so well. We would be in a much better place if even 1% of the sites validated properly.

It also shows the force of WordPress, with almost 3% of the sites linking there (and probably using WordPress).

Those were the top 30:

  1. www.facebook.com.
  2. twitter.com.
  3. wordpress.org.
  4. www.youtube.com.
  5. feeds.feedburner.com.
  6. www.linkedin.com.
  7. www.google.com.
  8. validator.w3.org.
  9. www.adobe.com.
  10. www.addthis.com.
  11. www.flickr.com.
  12. www.myspace.com.
  13. feedburner.google.com.
  14. www.blogger.com.
  15. www.macromedia.com.
  16. statcounter.com.
  17. www.amazon.com.
  18. www.addtoany.com.
  19. www.wordpress.org.
  20. creativecommons.org.
  21. bit.ly.
  22. en.wikipedia.org.
  23. facebook.com.
  24. www.statcounter.com.
  25. www.liveinternet.ru.
  26. www.histats.com.
  27. feeds2.feedburner.com.
  28. www.apple.com
  29. www.gnu.org
  30. www.stumbleupon.com

It is also interesting that people are linking to shorten URLS (bit.ly) so often too. What do you think? What sites do you have linked in your own sites?

Google top 1000 sites: Interesting stats about them

Google recently published a list with the top 1000 most visited web sites in the world. We found that list very interesting and decided to take a closer look at them.

These are stats we took:

  1. Web servers in use
  2. Programming language in use
  3. Sites using WordPress
  4. Sites using Jquery
  5. Sites using Google Adsense
  6. Sites using Google Analytics
  7. Sites that doesn’t work without the www
  8. Sites using China Cache

A few of these numbers really amazed us. Nginx, for example, was used in 15% of the sites, very close to IIS with only 17%. Jquery is being used in almost 30% of the top sites and 42% are using Google analytics.
