Hackers attacked computers systems at the U.S. Department of Health and Human Services late Sunday as the nation struggles to contain the spread of the COVID-19 coronavirus, according to a report on Monday. Bloomberg News reported that HHS suffered a cyberattack meant to slow the agency's systems but that data was not taken, citing three unidentified sources familiar with the matter. The attack appears to have tried to overload HHS servers with millions of pings over several hours, according to the report. Secretary of State Michael Pompeo and other officials in the Trump Administration are aware of the incident, Bloomberg said. HHS has yet to respond to an email requesting comment. On Monday, the Dow Jones Industrial Average DJIA, -0.87% fell 7%, the S&P 500 index SPX, -1.11% dropped 6.2%, and the tech-heavy Nasdaq Composite Index COMP, -1.07% fell 6.4%.
