Us government are afraid of growing cyber attacks in the world

Meet Hackers

US Director of National intelligence had made a statement that the cyber attacks would increasingly undermine US economic competitiveness and national security. That is why US intelligence agencies have made preventing new cyber attacks their priority.

The reports in his office had shown that Russia, China, Iran and North Korea are presenting the leading threats of cyber attacks. The Congress said that cyber attacks pose a greater threat than terrorism.
Mr. Clapper highlighted that in the past year there were a series of high-profile cyber attacks against the US targets. One of the attacks he mentioned, was the attack on Sony Pictures in November and also an attack on the Las Vegas Sands Casino Corporation last year.
