As America struggles to assess the damage from the devastating SolarWinds cyberattack discovered in December, ProPublica has learned of a promising defense that could shore up the vulnerability the hackers exploited: a system the federal government funded but has never required its vendors to use.
The massive breach, which U.S. intelligence agencies say was “likely Russian in origin,” penetrated the computer systems of critical federal agencies, including the Department of Homeland Security, the Treasury Department, the National Institutes of Health and the Department of Justice, as well as a number of Fortune 500 corporations. The hackers remained undetected, free to forage, for months.
