Can't be bothered to spend money on IT
I remember way back in early 2018 I may or may not have been staying at coughPullman London St Pancrascough.
Bored in the room I started to sniff the WIFI. Fuck me! Everything was wide open! I could see all other devices as no WIFI isolation was on. I could see, what I assumed was the PCs down in reception that people staying in the hotel could use. Worst still I found an old server available that had the controls to what, if I remember right, appeared to be a heating system.
I mentioned this to them on Twitter while I sat in my room, they'd have ignored it otherwise with just an e-mail. Granted, by the end of that day or the next it had been locked down more than it had been. Sadly, my limits were reached but if I knew more I probably could of gone further and found more holes.
I would of mentioned my room number in the hope I'd get the room free for helping. But I suspect I would of gotten kicked out instead.
