US$3m reward for hacker Evgeniy Bogachev highest ever by US officials

The US State Department and FBI are offering US$3 million for information leading to the arrest or conviction of Russian hacker Evgeniy Bogachev - the highest bounty US authorities have ever offered in a cybercase.

Bogachev is accused of running a computer attack network called GameOver Zeus that allegedly stole more than US$100 million from online bank accounts.

He has been charged with conspiracy, computer hacking, wire fraud, bank fraud and money laundering in Pittsburgh, Pennsylvania, in connection with his alleged role as administrator of the network .

Bogachev also faces federal bank fraud conspiracy charges in Omaha, Nebraska, related to his alleged involvement in an earlier variant of Zeus malware known as "Jabber Zeus".

Bureau officials believed he is still in Russia.

Joseph Demarest, head of the FBI's cybercrime division, said the agency was aware of 60 different cyberthreat groups linked to nation-states.
