WASHINGTON (AP) � U.S. government agencies and private companies rushed Monday to secure their computer networks following the disclosure of a sophisticated and long-running cyber-espionage intrusion.
Experts said the hack was almost certainly was carried out by a foreign state.
It was not yet clear who was responsible for the intrusion, though it was reportedly conducted by Russia, and the extent of the damage is not yet known.
But the potential threat was significant enough that the Department of Homeland Security’s cybersecurity unit directed all federal agencies to remove compromised network management software and thousands of companies were expected to do the same.
