The Islamic State's “Hacking Division” posted the names, addresses and photos of 100 U.S. service members online this past week in an effort to encourage sympathizers to kill the members.

The group claimed the personnel were involved in efforts against it in Syria, Iraq and Yemen, The New York Times reported. A Defense Department official told the publication that most of the information was readily available in public records or online.

The list also seems to include personnel who were written about in news stories about airstrikes on the group. The group said “various different servers” and “databases” yielded the information.

The group also stated in its post: “And now we have made it easy for you by giving you addresses, all you need to do is take the final step, so what are you waiting for?”
