A defector from the group alleges to have carried with him a USB drive containing more than your average backup of files. TheUSB is claimed to have details of 22, 000 ISIS fighters, including:
- Phone Number
- Blood Type
The paperwork it apparently contains is reported to be filled out before fighters come to the country, therefore representing foreign fighters coming to the group from abroad. The paperwork included questionnaires filled out by members of ISIS, including information regarding how they were recruited and would get to the group from their location, bypassing the restrictions and warning systems currently in place.
Currently, agencies around the world are trying to track down and confirm that this information is genuine, but if it does prove to be real information then this could help agencies track down recruiters and start cutting off access to the group from their countries.
