Sergey Vovnenko, whose aliases included "Flycracker" and "Darklife," was sentenced by U.S. District Judge Esther Salas in Newark, New Jersey, after pleading guilty last year to aggravated identity theft and conspiracy to commit wire fraud, Reuters reports.
The sentence was confirmed by the office of U.S. Attorney Paul Fishman in New Jersey, which said Vovnenko was also ordered to pay $83,368 in restitution.

Prosecutors said Vovnenko was an administrator of several online hacking forums and used his position to traffic in the data he stole.
Vovnenko fought extradition after he was detained by Italian authorities following his June 2014 arrest. He was extradited to the United States in October 2015.
