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.
Recent reports by security firms have identified cyber-espionage campaigns by Russian hackers thought to be working for the government. Targets have included NATO, the Ukrainian government and U.S. defense contractors. Russia is regarded by U.S. officials as being in the top tier of states with cyber-capabilities.
White House officials said that such an intrusion was not unexpected. “On a regular basis, there are bad actors out there who are attempting to achieve intrusions into our system,” said a second White House official. “This is a constant battle for the government and our sensitive government computer systems, so it’s always a concern for us that individuals are trying to compromise systems and get access to our networks.”
The Russian intelligence service was believed to have been behind a breach of the U.S. military’s classified networks, which was discovered in 2008. The operation to contain the intrusion and clean up the computers, called Buckshot Yankee, took months.
