Hackers Breach FBI’s System, Take Control of Fed Account to Send Thousands of Fake Emails

America’s top law enforcement agency has been hacked. Hackers managed to get into the Federal Bureau of Investigation’s external email system on Saturday, sending out thousands of spam emails warning about a cyberattack, according to The Washington Post.

The FBI admitted the hack, though the number of inboxes that received the emails was unclear Sunday. Some outlets like NBC News and The Hill reported at least 100,000 email addresses had received the messages.

“The FBI and CISA are aware of the incident this morning involving fake emails from an @ic.fbi.gov email account,” the FBI said in a statement. CISA is the acronym for the federal Cybersecurity and Infrastructure Security Agency.

“This is an ongoing situation, and we are not able to provide any additional information at this time. The impacted hardware was taken offline quickly upon discovery of the issue. We continue to encourage the public to be cautious of unknown senders and urge you to report suspicious activity to ic3.gov or cisa.gov,” the statement said.
