Reprogramming Your ATM For Fun And For Profit (Mainly For Profit)

from the not-so-hard-at-all dept

There was some buzz last week after CNN showed a video of an ATM machine that had been programmed to believe it had $5 bills instead of $20s (so any withdrawal actually gave you 4X the money you asked for). The guy who did this just walked in and knew the code to reprogram the ATM. He then left the ATM programmed that way, and the ATM gave a lot of people extra money for nine days before someone pointed out the problem. So how easy would it be for anyone else to do this? Apparently it's ridiculously easy. With a bit of hunting online, it's not too hard to obtain a copy of the manual for the type of ATM machine used, including instructions on how to switch it to diagnostic mode. You do need a password, but the manual lists the typical default passwords that it seems likely many of these ATM owners failed to switch. Hopefully, this new burst of publicity over the issue will encourage owners of the machines to change their passwords -- but if you happen to see certain ATMs with unusually long lines in the near future (and don't mind committing fraud), you might want to withdraw some money.

    well, when i get money from the bank teller, they count it out infront of me, making nice stacks of 100 or so. if 2 20s are stuck together, we both miss it because we both can't see it. then, i think i have the right ammount because it was counted for me so i spend.

    what about if it wasn't a bank teller, but a cashier from a retail store. i sold my books baack in colege and was supposed to get 45 bucks. i ended up getting close to 70 because the girl just anded me an extra 20. did i tell her? nope. if they are gonna rape me on text book prices, i'm gonna let them rape themselves with refunds.
