I just did a google search for my own site, using site:mysite.com, and I got some very weird results.

There's this subdomain that doesn't seems to exist on my FTP, and it's filling 10 pages of google results with spam, here's a picture:



There's nothing unusual in my DNS Zone Editor.

I've contacted my host and they are looking into it. But, how can this be possible in the first place? What should I look for if I want to understand how this happened and prevent such things from happening?

When this happens it is more often than not due to a hijacked or poisoned DNS zone file. Don't trust the zone file editor in your hosting panel as if the server has been compromised then this won't show you anything, instead run a manual DNS query for the offending domain name and check what the authoritative dns server is. If it is not your server then you need to get in touch with your domain name registrar, if it is the correct DNS server then you need to manually check the zone file in the shell (may need your hosting provider to do this for you). Not having a sub domain exist on your FTP directory means absolutely nothing as sites with different sub domains can exist on entirely separate servers with no hassle at all.
