Dans un tweet qui date du 16 Avril, Matt Cutts, a annoncé que Google a envoyé 20 000 messages via les Webmaster tools à des sites qu'il suspecte être piraté ou infecté par un code malveillant provoquant des redirections anormales.

Voilà à quoi ressemble le message de Google :

Dear site owner or webmaster of ..., We are writing to let you know that we believe some of your website’s pages may be hacked. Specifically, we think that JavaScript has been injected into your site by a third party and may be used to redirect users to malicious sites. You should check your source code for any unfamiliar JavaScript and in particular any files containing "eval(function(p,a,c,k,e,r)". The malicious code may be placed in HTML, JavaScript or PHP files so it's important to be thorough in your search. The following are example URLs from your site where we found such content:

....

In addition, it's also possible your server configuration files (such as Apache's .htaccess) have been compromised. As a result of this, your site may be cloaking and showing the malicious content only in certain situations. 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.
