How Tyupkin, the ATM Malware, Works

The hack, known as Tyupkin, requires criminals to enter a unique code into a machine that has already been compromised by the malware. A second Pin code – a random sequence of numbers generated at another location – is also needed to unlock the machine before it will dispense the cash. The video shown is Tyupkin in action.

It is believed that the criminals are headquartered somewhere in Europe but they have people worldwide.
