How to guess an ATM # in 15 tries.

This is a pretty crazy article....Some people found a way to hack Bank Machine pin numbers - very easily. Another article said how Citibank was trying to put a gag order on people explaining this.

after 3 tries doesn't it eat your card ?

They aren't hacking it from the machine. I think what they have found is a serious flaw in the encryption code so that previously it was very hard to figure out the Pin number, now using a computer algorithm they can do it in 15 tries. What this means is that an insider can exploit any persons PIN number. It stemmed from someone doing some research into "phantom" atm withdrawals. They estimate in a 30 minute period someone would be able to get 7000 PIN's at a limit of $300 per withdrawal, and walk away with 2.1 million $. So that is pretty serious. Any potential serious hacker could breach a banks security. What they are seeing is this has been known and there is a big rise in phantom withdrawal cases where people claim money came missing from there account. *edit* but they are trying to keep it hush hush. Citibank is taking it to court to keep it disclosed.

Guess they could save themselves a lot of money by reading this thread then ;)

Haha! Know any disgruntled bank employees?
