This Newsweek article has a pretty good breakdown: "The Federal Bureau of Investigation (FBI) email system had reportedly suffered a hack on Saturday morning amid several reports of messages sent from the agency's email infrastructure purporting to be a warning from the Department of Homeland Security (DHS) about a cyberattack." [1] "The Spamhaus Project, an international nonprofit organization based in Andorra and Switzerland that tracks spam, reported on Twitter that its analysis had shown the unusual emails are being sent from accounts "scraped" from the American Registry for Internet Numbers (ARIN) database." [1] "Our telemetry indicates that there were two 'spam' waves, one shortly before 5 AM (UTC) [12.am. E.T.] and another one shortly after 7 AM (UTC) [2a.m. E.T.]. The FBI has been getting many calls about it. We are therefore refraining from further actions against the sending IP addresses."
