Quote:A defector has allegedly leaked what appears to be a USB drive's worth of ISIS's secret data, including the personal information of 22,000 ISIS fighters. That personal data includes the fighters' names, phone numbers, hometown and even blood types---all information they apparently filled out on forms in the process of signing up to join the violent group.
Quote:Who's Been Exposed?A leak of 22,000 ISIS fighters' information would represent a significant chunk of the group's roster. Though the total number of ISIS fighters is unclear---and reports vary widely---the research firm Soufan Group says that foreign fighters makes up the majority of ISIS ranks and estimates their number at between 19,000 and 25,000, down from an estimate of 31,000 three months ago. Sky News reports that the leak does in fact contain the information of known ISIS recruits, such as the British former rapper Abdel Bary and the hacker Junaid Hussain, who was killed in a drone strike last summer.
