Two Romanian men recently admitted having participated in a scheme to hack into and steal payment data from U.S. merchants, including Subway restaurants, according to the U.S. Department of Justice.

"Iulian Dolan, 28, of Craiova, Romania, pleaded guilty Monday to one count of conspiracy to commit computer fraud and two counts of conspiracy to commit access device fraud, and Cezar Butu, 27, of Ploiesti, Romania, pleaded guilty to one count of conspiracy to commit access device fraud, the DOJ said," writes Computerworld's Grant Gross.

"The pair were among four Romanian nationals extradited in May after being charged last December with hacking into Subway vulnerable point-of-sale computers between 2009 and 2011," writes The Register's John Leyden. "The scheme led to the compromise of more than 146,000 payment cards and more than $10m in losses."

"The hackers didn’t confine their efforts to Subway," writes Betabeat's Steve Huff. "Mr. Dolan admitted he wormed his way into 'several hundred' American payment systems, downloading financial information for 6,000 people. He has received a seven-year prison sentence for his trouble. His countryman Mr. Butu will spend nearly two years in prison."
