The US Department of Health and Human Services, a key part of the federal response to the fast-spreading coronavirus outbreak, was hit by a cyberattack on Sunday night, prompting a response from the National Security Council, Bloomberg said on Monday.
Multiple hacking incidents appeared aimed at slowing down the department's systems, Bloomberg reported, citing three people familiar with the matter.
The cyberattack prompted the NSC at the White House to push out an overnight tweet after US officials realized there had been an intrusion and that false information was circulating about the coronavirus response, Bloomberg reported.
"Text message rumors of a national #quarantine are FAKE. There is no national lockdown. @CDCgov has and will continue to post the latest guidance on #COVID19. #coronavirus," NSC tweeted overnight.
Representatives for HHS did not immediately respond to a request for comment on the report. Representatives for the NSC could not be immediately reached.
