Hackers Break Into FBI Mail Server: Spamhaus

Washington, November 14 (UNI/Sputnik) A US Federal Bureau of Investigation (FBI) mail server has been the target of a cyber attack, Project Spamhaus, which tracks spam and cyber threats.
“The following graph shows email traffic from the FBI mail server ( | involved. You can clearly see the two spikes caused by the fake [cyber attack] warning last night,” Spamhaus tweeted, posting a photo of the activity graph.
According to Spamhaus, the emails containing the fake Department of Homeland Security (DHS) warning were sent to addresses “scraped” from the American Registry for Internet Numbers (ARIN) database.
“While the emails are indeed sent from FBI/DHS-owned infrastructure (the LEEP Portal), our research shows that these emails *are* fake,” Spamhaus said, claiming the emails “caused a lot of disruption.” because the headers are real, they really come from FBI infrastructure.”
In a subsequent tweet, Spamhaus said other reports suggest Saturday’s hacking attack was not limited to a single database.
“Other harvested emails unrelated to ARIN were included in the spam,” Spamhaus said.
Spamhaus Project told BleepingComputer that the fake emails reached at least 100,000 recipients and the number of mailboxes affected was likely much larger.
The FBI said in a statement on Saturday that it was “aware of the incident this morning involving false emails from an email account.”
No further details were provided, but the FBI said the impacted hardware was taken offline quickly upon discovery of the issue.
