(Reuters) -Hackers compromised a Federal Bureau of Investigation email system on Saturday and sent tens of thousands of messages warning of a possible cyberattack, according to the agency and security specialists.
A copy of an email posted by Spamhaus on Twitter showed a subject line of “Urgent: Threat actor in systems” and appeared to end with a sign-off from the Department of Homeland Security.
The FBI is part of the Department of Justice.
Bloomberg News reported the incident on Saturday.
