It's so funny to walk down the hall and hear people bitch about how they somehow can no longer log onto their internet even though they can see it and it was still unlocked..Ah the good times.
About 10 years ago while I was doing network administration for an ISP I discovered a lawyer in the building had completely open wifi. To make matters works they were using a completely peer to peer based network with full public read/write access on their file server where they stored all their client case files.
Because there were several law offices in the building I had no idea which one it was so I started sending letters to their laser printer warning them. Eventually they figured out who was sending them and came down to ask me what to do. Turns out they new nothing about IT and had a guy on contract who told them everything was groovy.
I ended up throwing basic wpa protection on their wifi and referred them to a friend who did smb it consulting. Old guy got fired, my friend picked up a new contract and found he basically had to redo their entire network. I ended up getting a gift certificate to a local b&b as a thank you.
