So I was looking at the linux environment at my new job. Found 2 VM's in the local network, only one of them is documented. Noone knows about the other one or what it does, let alone usernames and passwords.

Spent over an hour trying to break in, only to find out that a couple of bored devs, that have long since left the company, set up a game server on there and noone noticed it for the past 3 years..
