Did Russia Just Hack the White House?

Intruders are trying to crash the White House inside and out. While the Secret Service tries to clamp down on people jumping the fence along Pennsylvania Avenue, federal authorities have been battling gatecrashers of the cyber variety.

Hackers who may have been working for the Russian government succeeded in breaching unclassified networks at the White House earlier this month, leading to disruptions as U.S. authorities moved to secure the building's computers.

A White House official confirmed Wednesday morning that authorities "identified activity of concern on the unclassified Executive Office of the President network."

"Any such activity is something we take very seriously. In this case, we took immediate measures to evaluate and mitigate the activity," the official said.
