Originally published at: http://www.myce.com/news/cia-fires-contractors-stealing-vending-machine-82189/ Several CIA contractors have been fired after illegally 'hacking' vending machines. In total they stole for more than $3000 worth of candy. One employee discovered that if a cable, that connected the vending machine with a cloud based payment system, was unplugged, the vending machine accepted unfunded cards.
Took them long enough to figure out they were getting ripped off. LOL.
Other problem is the original developer probably knew about it and used it to their own devices as well. Why else would it still be there in the vending machine.
