I recently had a #1 ranking site for all it's major keywords get cracked along with 2 others I manage on the same server. It was done thru the ftp. That is what my host claimed anyway. They claimed I introduced it but this site had done so well I hadn't touched it in 6 months.
In my case, they did a little trick in my .htaccess file but it seems some hosts have some ftp problems..so make sure you change that password not just your cpanel.
BTW..Google has evidently creamed my #1 site now. So I decided to take this oppurtunity to revamp the site. Make lemonade from the lemons.
It's interesting google gave a heads up on his. Big G obviously thought it wasn't an intentional by the webmaster and must have recognized the pattern. Very interesting.
