Two of the four Romanian hackers charged with the 2011 remote hijacking of credit card processing systems of more than 150 Subway restaurants, as well as other retailers in the United States, have pleaded guilty to the crimes. According to documents filed on Monday in the U.S. District Court in New Hampshire, Iulian Dolan, 28, pleaded guilty to one count of conspiracy to commit computer fraud and two counts of conspiracy to commit credit card fraud, and Cezar Iulian Butu, 27, pleaded guilty to one count of conspiracy to commit credit card fraud. The defendants were both arrested in August 2011 upon entering the Untied States. According to federal prosecutors, the sting resulted in more than $10 million in losses.
