Cyberspace Conflict Growing More Destructive, NSA’s Chief Says

Conflict in cyberspace will worsen as governments, criminals and others carry out more sophisticated and destructive hacking attacks, creating a threat comparable to what the U.S. faced during the Cold War, according to the head of the National Security Agency.

Potential adversaries may have intentionally left evidence that they’ve hacked into industrial control systems to send a message that America is at risk of a destructive attack if tensions escalate, said Navy Admiral Michael Rogers, head of both the NSA and U.S. Cyber Command.
