Have any of our European members heard of this?
From the link:
In a black box attack, criminals cut holes into the fascia or top of the ATM to gain access to its internal infrastructure. From there, the ATM's cash dispenser is disconnected and attached to an external electronic device - the so-called black box. The box sends commands to the dispenser to push out cash, bypassing the need for a card or transaction authorization.
Seems more efficient than card skimmers, which won't work with chip cards, but also much more obvious/risky.
