On December 6, 2015, the ISIS-affiliated CyberCaliphate hacker group posted a "kill list" video on its official Twitter account. The video includes names and details of U.S. military personnel and the message to "kill them wherever you find them."
It should be mentioned that CyberCaliphate's Twitter account was subsequently removed, leading the group to issue a statement and security warning on the messaging app Telegram.
Following are screenshots from the video:
