Hack Brief: ISIS Data Breach Identifies 22,000 Members

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. A Syrian opposition newspaper has obtained at least a portion of that information, along with the British television network Sky News and German intelligence officials. A German law enforcement official tells CNN that the information appears to be real.
