The US Federal Bureau of Investigation (FBI) has made a campaign against cyberthreats one of its "highest priorities," with China, Russia and Iran in the crosshairs, the AFP quoted the bureau's chief as saying on Thursday.
FBI Director Robert Mueller told the House intelligence committee that cyber-espionage constituted "one of the most significant and complex threats facing the nation."
When asked to name the worst offenders around the globe that pose a threat to the United States, Mueller said: "You have countries such as Russia and China, others, Iran perhaps, who have capabilities that we're alert to."
"Addressing this cyberthreat will be among the FBI's highest priorities now and in the years to come," he told lawmakers.
