Having a key to the office and having a key to the network closet are not the same thing. The article said only four people had access to the network closet. So did this guy break into the closet to plant the pi?

I think he got off way to easy.

You'd have to ask the person who wrote the story. It's possible they said "a key" and meant "a set of keys" or something. Either way you're right the person who planted the RPi was quite lucky to get away with only a stern talking to.

oooh, I didn't realise they still had the key at that point. OK, I wouldn't have even said that - I'd have asked for the key back and boxed the remaining stuff myself. TBH, I'm surprised to what extend the employee would of had a bunch of stuff there - did they have furniture there or something?!

Yeah it sounds like the person was on good terms with the company and was trusted enough, must have stung for whoever made the decision to trust the ex-employee to be sorta betrayed like that. The blog author is somewhere in the comments here, I don't know if they're willing to share much more info but let's see what they say.

So the article mentions:

> It was registered (or first deployed or set up?) on May 13th 2018

and the post itself is dated 2019-01-16

Since it says:

> he could still have a key for a few months

I assumed that by then the employee had given back the key, but I guess I was making a few assumptions about when this happened, and when the device had been installed - they don't actually say what date the RADIUS logs revealed they had accessed the network.
