On Monday, a Russian pleaded not guilty to charges that could imprison him for decades. A resident of Moscow who was accused of taking a part on the biggest cyber crime ring prosecuted in the US would fight the allegations against him.

Dmitriy Smilianets, 29, was charged of conspiring with a group of hackers from Russia and the Ukraine. The hackers stole over 160 million credit card numbers in a series of violations that cost victim corporations of up to USD300 million. Smilianets' lawyer told Reuters that he would fight the accusations. He also added that he was investigating about potential irregularities in the circumstances of his client's 2012 arrest in the Netherlands.

Financial corporations like NASDAQ and Heartland Payment Systems Inc. were some of the firms that were infiltrated. Well-known companies like JetBlue Airways Corp and retailer from Texas, JC Penney Co., were also victims of the cyber crime. Prosecutors claimed that Smilianets sold all of the stolen data that involved credit card information starting at USD10 for a number from the US and USD50 for a number from Europe.
