I am not surprised at all. Maybe 7 years ago I got called in to clean up a website "hack" where the site had a bunch of malicious JS on it. Site was hosted on GoDaddy.<p>Pulled the site down locally and started the regular process of find/remove, but nothing was showing up. Hosting the site locally, the JS wasn't being put on the page. Checked all the server files for stuff like php.ini, user.ini, etc etc. Nothing was showing up.<p>Created a plain info.php file on the account. That had the JS injected into it.<p>Started searching for other sites with the same JS, found a bunch, dozens. Started a search for "neighbor" sites to the one I was investigating, ones that most likely were on the same server. They ALL had the JS injected. Server was owned.<p>I alerted the client and sent a note into GoDaddy, like you need to check this out. Got a response that it was impossible for the server to be compromised and I should buy their Sitelock service for security. Instead we requested a migration to another server and that cleared up the issue.
