CIA head: Cyberattack threat ‘keeps me up at night’

CIA Director John Brennan says the potential of a destructive cyberattack on American infrastructure is what worries him the most.  

“That cyber environment can pose a very, very serious and significant attack vector for our adversaries if they want to take down our infrastructure, if they want to create havoc in transportation systems, if they want to do great damage to our financial networks,” he said Sunday on CBS’s “60 Minutes.”

“There are safeguards being put in place,” he added. “But that cyber environment is one that really is the thing that keeps me up at night.”

Although data breaches and hacks have become commonplace over the past few years, officials have yet to see a truly destructive cyberattack that causes physical damage to American infrastructure.
