Simplest answer is probably the right one in this case:
Someone at Linode did it. Ran a script to see how many bitcoin files there were on all the machines (they probably do these types of queries for anti-virus/whatever anyways) and took a customer support password to log in and get the coins. If he did it right he still might be working there, as it is easy to get credentials from friends/coworkers (even though it should be really really hard).
