The organization that claims to be the hacking arm of ISIS published a list of 3,600 New Yorkers in a supposed hit list.
American officials played down the seriousness of the threat.
"Every so often, some group…puts out names to scare people. So far, praise God, there's been no follow-up on any of this,” said New York Senator Charles Schumer, who suggested this was not the work of the Islamic State.
The FBI spent much of the last few days making sure it contacted Americans on the list issued by United Cyber Caliphate.
One woman shared a voicemail she received with The Daily Dot:
"Good afternoon, this is Special Agent [name removed] with the FBI," said the voice. "Please give me a call back regarding information of yours that might have leaked via a social media portal on an ISIS platform."
