The U.S. Health and Human Services Department suffered a cyber-attack on its computer system Sunday night during the nation’s response to the coronavirus pandemic, according to three people familiar with the matter.
The attack appears to have been intended to slow the agency’s systems down, but didn’t do so in any meaningful way, said the people, who asked for anonymity to discuss an incident that was not public.
The National Security Council’s tweet on Sunday night was related to the hacking and the release of disinformation, according to the people. The government realized Sunday that there had been a cyber intrusion and false information was circulating."
