The feds' computer experts identified a server that contains 10,000 bank account details pilfered from 5,200 computers, 160 of which belongs to NASA. Besides stealing money himself, Kuzmin also rented out the Gozi virus to other hackers for $500 a week. He earned $250,000 from that particular venture.

While the DOJ didn't release the details of how he contributed, it's clear whatever he did worked: he didn't get additional jail time.
