A New Zealand super hacker, who discovered a way to hack ATM machines and make them spew out cash, has died in San Francisco.
Barnaby Jack was found dead on Thursday evening by "a loved one" at an apartment on Nob Hill and foul play has been ruled out, a police spokesman told Reuters.
The San Francisco Medical Examiner's Office said it was conducting a post mortem examination, but it could be a month before the cause of death was determined.
Mr Jack, in his 30s, originally from Auckland but based in the US, was set to deliver a talk about hacking pacemakers and other wireless implantable medical devices, 3News reported.
He gained prominence in 2010 in Las Vegas when he demonstrated to audiences how to hack into the computer system of an ATM to force it to give up its cash.
