As the US ramps up its response to the spread of COVID-19, the Health and Human Services Department was hit with a cyberattack, according to a new report from Bloomberg.

Citing three unnamed sources familiar with the matter, Bloomberg reported that the cyberattack aimed to slow down HHS computer systems Sunday night, but were unsuccessful in doing so. The attack attempted to flood HHS servers with millions of requests over the course of several hours.

Following the attempted intrusion, federal officials reportedly became aware that false information was being circulated. The false-information campaigns were related to the hack, but no data was reportedly stolen from HHS systems.

The National Security Council tweeted Sunday night that there were false rumors circulating about a national quarantine, calling the rumors “#FAKE.”

A representative for HHS did not immediately respond to a request for comment.
