Banks have said very little about their losses to cyber-thieves, but federal authorities say the figures have been growing rapidly. In the case of the Citibank-branded ATMs, the perpetrators penetrated a network linking 2,200 kiosks inside 7-Eleven stores from late 2007 until at least February 2008.
The breach occurred on a back-end system that had been outsourced by 7-Eleven before the system was moved over to Cardtronics' internal network.
