Story highlights Legitimacy of the list is questionable

Much of the information it contains is outdated

Message claims to provide phone numbers, locations, and "passwords" for U.S. government and military personnel

(CNN) A group calling itself the Islamic State Hacking Division this week posted online a purported list of names and contacts for Americans it refers to as "targets," according to officials.

Though the legitimacy of the list is questionable, and much of the information it contains is outdated, the message claims to provide the phone numbers, locations, and "passwords" for 1400 American government and military personnel as well as purported credit card numbers, and excerpts of some Facebook chats.

"We are extracting confidential data," the message says, "and passing on your personal information to the soldiers of the khilafah, who soon with the permission of Allah will strike at your necks in your own lands!"

Many of the phone numbers and email addresses on the list were not in service, when tested by CNN. But one person on the list, reached by phone, confirmed that he had previously served in the U.S. military. He asked not to be named, but said he had recently been notified by the Pentagon that his name and personal information were on the list. Another, reached by email, confirmed that she was a government employee who has been warned by the military about being on the list.

Several online terror trackers were unable to confirm whether the list actually came from ISIS. The FBI and Pentagon both say they are investigating.
