USA - Russia acted with impunity when it hacked US government servers in a global cyber-espionage campaign and could do far more damage next time — like cutting off the nation’s water and electricity supply, GOP Senator Mitt Romney said Sunday. Speaking on NBC’s “Meet the Press,” the Utah senator said the massive cyberattack discovered earlier this week, which officials say could be the biggest hack on the American government ever, must be met with a vigorous response and without delay. “They potentially have the capacity to cripple us economically, they went to our businesses. They have the potential to also cripple us with regards to our water and electricity and so forth.” Romney added: “They don’t need rockets to take those things out.” Officials say the breach could potentially endanger American security for years to come. While President Trump surmised the attack might have come from China, security officials in his administration pointed directly to Russia. “We can say pretty clearly that it was the Russians who were responsible,” Secretary of State Mike Pompeo said Friday.
