U.S. officials say Russian government hackers have penetrated energy and nuclear company business networks

Overview

"Russian government hackers were behind recent cyber-intrusions into the business systems of U.S. nuclear power and other energy companies in what appears to be an effort to assess their networks, according to U.S. government officials."

Why is this important?

"The campaign marks the first time Russian government hackers are known to have wormed their way into the networks of American nuclear power companies, several U.S. and industry officials said. And the penetration could be a sign that Russia is seeking to lay the groundwork for more damaging hacks."
