On July 26, 2015, jihadi supporters on Twitter began circulating images containing what they claim is the personal info of NATO soldiers which was obtained by ISIS after having hacked its website. The info included names, countries of origin, phone numbers, and more.
Note: Some of the info in the images above has been blurred out by MEMRI.
