The department of Homeland Security, the country Department and the National Institutes of Health on Monday joined the heel of known victims of a months-long, highly sophisticated digital spying operation by Russia whose hurt remains uncertain but is presumed to be extensive, experts say.
The list of victims of the cyberespionage, which already included the Treasury and Commerce departments, is expected to grow and to include more federal agencies and numerous private companies, said officials and others familiar with the matter, who spoke on the status of anonymity because it is under investigation.
SolarWinds, the maker of widely used network-management software that the Russians manipulated to enable their intrusions, reported in a federal securities filing Monday that fewer than 18,000 of its customers may hold been affected. Thats a small slice of the companys more than 300,000 customers worldwide, including the Pentagon and the white House, but relieve represents a large number of important networks. Russia has denied any role in the intrusions.
