Prosecutors say this was a highly organized, sophisticated cyber crime operation run by people from the U.S., Ukraine, China, Estonia and Belarus. The indictment says they got started by driving around in a car with a laptop computer and tapping into retail stores' wireless networks. The technique is called "wardriving."

TJ Max, Barnes and Noble, Sports Authority, and Office Max are some of the retail stores where credit and debit card numbers were captured. The stolen information was sent to computers overseas, and from there, prosecutors say it was used to make fraudulent purchases, illegal cash withdrawals from ATMs, and even manufacture fake credit cards. US prosecutors say this particular gang did tens of millions of dollars in business.

Allan Paller is a computer security expert with the Sans Institute in Washington says the most troubling aspect of this cyber crime case has to do with the way some of the affected retail stores handled the situation: "Either they didn’t know there was a breach, or knew and didn’t tell."
