There’s been concern for quite some time now that Russia has already infected U.S. critical infrastructure with viruses but are yet to be activated and unleashed until there’s a need or the time is right.
Attackers hacking into American computer networks appear to be leaving “cyber fingerprints” to send a message that critical systems are vulnerable, the top US cyber-warrior said Thursday.
Admiral Michael Rogers, director of the National Security Agency and head of the Pentagon’s US Cyber Command, made the comments to a US Senate panel as he warned about the growing sophistication of cyber threats.
“Private security researchers over the last year have reported on numerous malware finds in the industrial control systems of energy sector organizations,” Rogers said in written testimony.
“We believe potential adversaries might be leaving cyber fingerprints on our critical infrastructure partly to convey a message that our homeland is at risk if tensions ever escalate toward military conflict.”
Rogers told senators that “threats and vulnerabilities are changing and expanding at an accelerated and alarming pace,” forcing the US to step up defensive measures.
