The curious case of the Raspberry Pi in the network closet

Christian Haschek found a Raspberry Pi attached in a network closet at the company he works for, and since nobody knew what it was or where it came from, he and his colleagues decided to investigate. I asked him to unplug it, store it in a safe location, take photos of all parts and to make an image from the SD card (since I mostly work remote). I have worked on many Raspberry Pi projects and I felt confident I could find out what it does. At this point nobody thought it was going to be malicious, more like one of our staffers was playing around with something. Interesting - but worrisome - story.
