The presentation was scheduled for hacker conference DEFCON:
Well-known hacker Barnaby Jack has died in San Francisco, a week before he was due to show off techniques for attacking implanted heart devices that he said could kill a man from 30 feet away.
The San Francisco Medical Examiner’s office said he died in the city on Thursday. It gave no details.
Jack, a security expert, became one of the most famous hackers on the planet after a 2010 demonstration in which he forced ATMs to spit out cash, dubbed “Jackpotting.”
