Server (Not) Hacked!
I once had a client whose machine was typing stuff and moving the mouse about. He immediately jumped to the conclusion that the (external) web/mail server had been hacked. No I don’t know either.
After failing to make sense of “it’s just doing things on its own” and asking him to unplug the network cable to rule out a remote access attempt, I asked him if he was using a wireless keyboard.
Turns out someone on the floor below was using the same make/model/frequency and operating both machines. At least it didn’t need a trip out.
Biting the hand that feeds IT
