Watch your bank account

Some hardware commonly used in ATMs has been shown to be crackable. It allows people inside the banking system to determine the PIN number for an account in an average of 24 attempts. Rather than admitting that the hole exists and working on a fix, Citibank is attempting to use legal means to prevent people from finding out about it. They have to know that the people who would use the exploit have already downloaded the instructions. I can only conclude that they don't want their customers to find out that their accounts are not secure.
