ISIS Publishes Information On 77 US And NATO Military Facilities

ISIS also published details on people in 21 countries. One worker at a South Korean welfare organization was on the list. CNN reports officials have put that person under protection, but they are unsure why the person is a potential target. 

ISIS is said to be using Telegram, an encrypted messaging service, to publish their info. It's been a favored tool of a pro-ISIS hacker group known as the United Cyber Caliphate, which has taken to posting vast "kill lists." 

South Korea's military said Monday it is willing to lend security forces to American units stationed in South Korea. 

Last month, the U.S. military told CNN it set its North American bases at "Force Protection Bravo," the third-highest possible threat level, in response to concerns over terrorist attacks.
