AP Tackles Citibank ATM Heist - Via Threat Level:

The Associated Press chimes in today on the Citibank ATM hacking story you've been following here. The article doesn't shake loose any new information, but the mainstream press attention makes it all but inevitable that Citibank and Cardtronics will eventually have to come clean on the breach. So far, neither company has revealed how many PINs were compromised, or how much money has been stolen.

It's unclear how many Citibank customers were affected by the breach, which extended at least from October 2007 to March of this year and was first reported by technology news Web site Wired.com. The bank has nearly 5,700 Citibank-branded ATMs inside 7-Eleven Inc. stores throughout the U.S., but it doesn't own or operate any of them.

That responsibility falls on two companies: Houston-based Cardtronics Inc., which owns all the machines but only operates some, and Brookfield, Wis.-based Fiserv Inc., which operates the others.

A critical issue in the investigation is how the hackers infiltrated the system, a question that still hasn't been answered publicly.
