Viet Quoc Nguyen , 28 , is charged with hacking at least eight email service providers between February 2009 and June 2012 and obtaining more than one billion email addresses .

The other defendant , Canadian David-Manuel Santos Da Silva , 33 , was charged with conspiracy to commit money laundering . He is the co-owner of a company called 21 Celsius Inc , that allegedly struck up a marketing arrangement with Nguyen and Vu to generate revenue and launder the proceeds , according to the Justice Department . The two men made $ 2 million from sales on those products over two years . “ Those individuals who line their pockets with money gained through deceiving others should know they will not go undetected and will be held accountable , ” said Special Agent in Charge Veronica F. Hyman-Pillot of the IRS Criminal Investigation Division . Vu was taken into custody in the Netherlands in 2012 and was extradited to the US at the beginning of March .

He has pleaded guilty to to conspiracy to commit computer fraud . Da Silva was nabbed by authorities in February at Ft. Lauderdale International Airport trying to leave the country . 'This case reflects the cutting-edge problems posed by today 's cybercrime cases , where the hackers did n't target just a single company ; they infiltrated most of the country 's email distribution firms , ' said acting U.S. Attorney John A. Horn . 'And the scope of the intrusion is unnerving , in that the hackers did n't stop after stealing the companies ' proprietary data — they then hijacked the companies ' own distribution platforms to send out bulk emails and reaped the profits from email traffic directed to specific websites .
