Every server on the internet is open to being attacked, IP addresses and domain names are scanned each day and 0-day vulnerabilities are scanned for all the time.
If a vulnerability is found, they exploit it to grab control of the server.
Usually it's just for spam, or to grab machines to expand a botnet, etc.
Anyhow, farm... this is just what people call many (usually cheap) servers that work together to share a larger piece of work... in our case we have a bunch of machines that make web pages for this site.
