The U.S. Department of Energy has confirmed that its computer systems were hacked into last month. According to The New York Times, the federal agency sent around an internal e-mail on Friday telling its employees about the cyberattack.
"The Department of Energy has just confirmed a recent cyber incident that occurred in mid-January which targeted the Headquarters' network and resulted in the unauthorized disclosure of employee and contractor Personally Identifiable Information," the e-mail said.
The agency said that it is working to figure out the "nature and scope of the incident" but that so far it believes "no classified data was compromised." It's unclear which divisions within the Department of Energy were attacked or who was behind the hack.
