The defendants were identified as Russians Vladimir Drinkman, Aleksander Kalinin, Roman Kotov and Dmitriy Smilianets, and Ukrainian Mikhail Rytikov. Authorities say one suspect is in the Netherlands and another is due to appear in U.S. District Court in New Jersey next week. The whereabouts of the three others were not immediately clear.
The prosecution builds on a case that resulted in a 20-year prison sentence in 2010 for Albert Gonzalez of Miami, who often used the screen name "soupnazi" and is identified in the new complaint as an unindicted co-conspirator. Other unindicted co-conspirators were also named.
Prosecutors identified Drinkman and Kalinin as "sophisticated" hackers who specialized in penetrating the computer networks of multinational corporations, financial institutions and payment processors.
Kotov's specialty was harvesting data from the networks after they had been penetrated, and Rytikov provided anonymous web-hosting services that were used to hack into computer networks and covertly remove data, the indictment said.
Smilianets was the information salesman, the government said.
All five are charged with taking part in a computer hacking conspiracy and conspiracy to commit wire fraud. The four Russian nationals are also charged with multiple counts of unauthorized computer access and wire fraud.
The individuals who purchased the credit and debit card numbers and associated data from the hacking organization resold them through online forums or directly to others known as "cashers," the indictment said. According to the indictment, U.S. credit card numbers sold for about $10 each; Canadian numbers were $15 and European ones $50.
The data was stored on computer servers all over the world, including in New Jersey, Pennsylvania, California, Illinois, Latvia, the Netherlands, Bahamas, Ukraine, Panama and Germany.
The cashers would encode the information onto the magnetic strips of blank plastic cards and cash out the value, by either withdrawing money from ATMs in the case of debit cards, or running up charges and purchasing goods in the case of credit cards.
