Hackers breach some White House computers (Source washingtonpost.com) Hackers thought to be working for the Russian government breached the unclassified White House computer networks in recent weeks, sources said, resulting in temporary disruptions to some services while cybersecurity teams worked to contain the intrusion. White House officials, speaking on the condition of anonymity to discuss an ongoing investigation, said that the intruders did not damage any of the systems and that, to date, there is no evidence the classified network was hacked. “In the course of assessing recent threats, we identified activity of concern on the unclassified Executive Office of the President network,” said one White House official. “We took immediate measures to evaluate and mitigate the activity. . . . Unfortunately, some of that resulted in the disruption of regular services to users. But people were on it and are dealing with it.” The FBI, Secret Service and National Security Agency are all involved in the investigation. White House officials are not commenting on who was behind the intrusion or how much data, if any, was taken.
