you quoted a piece of what I said. My statement was not a "general" statement about hacking encrypted files, it was about hacking encrypted files that decipher PIN's.
.............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.
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.
