Hackers are getting our bank security pin codes!
Hackers have crossed into new frontiers by devising sophisticated ways to steal large amounts of personal identification numbers, or PINs, protecting credit and debit cards, says an investigator. The attacks involve both unencrypted PINs and encrypted PINs that attackers have found a way to crack, according to an investigator behind a new report looking at the data breaches.
Some of the attacks involve grabbing unencrypted PINs, while they sit in memory on bank systems during the authorization process. But the most sophisticated attacks involve encrypted PINs. Sartin says the latter attacks involve a device called a hardware security module (HSM), a security appliance that sits on bank networks and on switches through which PIN numbers pass on their way from an ATM or retail cash register to the card issuer. The module is a tamper-resistant device that provides a secure environment for certain functions, such as encryption and decryption, to occur. According to the payment-card industry, or PCI, standards for credit card transaction security, PIN numbers are supposed to be encrypted in transit, which should theoretically protect them if someone intercepts the data. The problem, however, is that a PIN must pass through multiple HSMs across multiple bank networks en route to the customer's bank. These HSMs are configured and managed d

According to the payment-card industry, or PCI, standards for credit card transaction security, PIN numbers are supposed to be encrypted in transit, which should theoretically protect them if someone intercepts the data. The problem, however, is that a PIN must pass through multiple HSMs across multiple bank networks en route to the customer's bank. These HSMs are configured and managed differently, some by contractors not directly related to the bank. At every switching point, the PIN must be decrypted, then re-encrypted with the proper key for the next leg in its journey, which is itself encrypted under a master key that is generally stored in the module or in the module's application programming interface, or API.
