Barnaby Jack, 35, died Thursday night at 7:50 p.m. local time. The San Francisco Medical Examiner’s office would not release further details of Jack’s death. Jack was best known for his work on embedded devices, from the financial world to the medical one. He is best remembered by much of the public for his research in 2010, where he disclosed flaws that enabled a person to force ATMs to spit out cash, a process he called Jackpotting. Black Hat, where Jack was slated to present his ICD research next week, said that the time slot for his talk will not be replaced.”]
