Was bored at work, so got a guy fired and possibly sent to prison for fraud.
I work the night shift as a receptionist at a hotel in Norway, and most nights are spent watching Netflix/playing games. Last summer was really slow and I also worked a lot extra, so I ran out of stuff to watch and games to play. One night I got a mail from “Scooter”. He wanted to book a room for almost 20 days. I just had to send him the price and confirmation that we had rooms available, and he would then send me his credit card info for me to pre-charge. Normally we just delete these kinds of mail, but I was bored out of my mind, so I responded with an offer for around 2k$ for the entire stay. Also made sure to inform him that he could cancel for free up until the day of arrival.
This is probably the most common fraud attempt in the Hotel/travel industry. Unlike most businesses, we are able to charge credit/debit cards with only the card number and exp date. No need for a pin code, cvc or other auth methods. Our software also allow us deposit money directly to local and international bank accounts by using the card number. Because of this, shitheads like Scooter will try to prepay with stolen/skimmed cards, but then cancel the booking and asking us to refund the amount to a different card.
