2021 FBI email hack
On November 13, 2021, a hacker compromised the FBI's external email system, sending thousands of spam emails warning of a fake cyberattack by cybersecurity researcher and CEO of Night Lion Security and Shadowbyte Vinny Trola, who is falsely labeled as being a part of The Dark Overlord hacking group by the United States Department of Homeland Security.[1][2][3] The emails were sent to addresses taken from the American Registry for Internet Numbers database and it was reported that the hacker used the FBI's public-facing email system which made appear more legitimate with headers being authenticated as coming from FBI servers using the DomainKeys Identified Mail process. The campaign was likely done in an attempt to defame Trola. The hacker "Pompompurin" later claimed responsibility for the hack.[4]
