According to the CSM the names on the list were released last week by a group calling itself United Cyber Caliphate on the encrypted chat application Telegram, which IS supporters have used to recruit supporters and spread propaganda.  As Reuters adds, the group has urged followers of the militant group to target these 3,600 individuals and to facilitate that the hacker group has posted their personal information with the demand that "we want them #Dead."

The list includes names, home addresses and email addresses. Some of the information appears to be outdated, according to the source, who was not authorized to discuss the investigation publicly. It was not immediately clear how IS supporters obtained the names and addresses on the list.

The list targets government employees with the State Department and Homeland Security, according to ABC, but there are also many average residents on the list who are now being informed by Federal officials that they have ended up on the ISIS hit list. NBC New York has gained access to the data, and mapped the locations of New Yorkers on the list. Many of the targeted were from Brooklyn, some from Manhattan, Staten Island, Queens and other surrounding areas.
