(LiveHacking.Com) – Accoring to Matt Cutts, Google’s friendly face, the search giant has sent emails to 20,000 webmasters warning them about possible hacker activity on their sites. The “your site might be hacked” message was sent to websites which exhibited weird redirect behavior.
“We encourage you to investigate this matter in order to protect your visitors. If your site was compromised, it’s important to not only remove the malicious (and usually hidden) content from your pages, but also to identify and fix the vulnerability. A good first step may be to contact your web host’s technical support for assistance. It’s also important to make sure that your website’s software is up-to-date with the latest security updates and patches,” wrote Google.
Google have taken proactive action in the past to protect its users. Last year it removed web sites hosted on the .co.cc free Web hosting service from its search results due to the fact that such a large percentage of the sites were low-quality or set-up only for spam.
