FBI aware of 60 different cyberthreat groups linked to nation-states

The FBI is aware of 60 different cyber threats groups linked to nation-states, a senior bureau official said on Tuesday.

Joseph Demarest, head of the FBI's cyber crime division, also said the bureau learned within a month of Sony Pictures first report of a large-scale cyber attack that North Korea was behind it.

On Tuesday the FBI and State Department also announced a $3 million reward for information leading to arrest or conviction of Russian Evgeniy Bogachev, who is charged in the United States with running a computer attack network called GameOver Zeus that allegedly stole more than $100 million from online bank accounts.

FBI officials said the $3 million reward for Bogachev, who is believed to be in Russia, is the highest offered in a US cyber crime case.
