Hacker Barnaby Jack has died in San Francisco
Barnaby Jack, a computer-security professional with a showman's flair for demonstrating technical weaknesses in ATMs and medical devices, has died. He was 35.

A police spokesman said that he was found dead on Thursday evening by "a loved one" at an apartment on Nob Hill in San Francisco and that foul play had been ruled out. The San Francisco Medical Examiner's Office said it was conducting an autopsy, though it could be a month before the cause of death was determined.


Jack, originally from New Zealand, was director of embedded device security at IOActive, a security consulting firm with offices in Seattle and London. He was known for attention-grabbing hacking demonstrations that made him a sought-after presenter at computer-security conferences. In 2010, he showed how he could break into ATM machines and make them spit out cash, a stunt he performed live on stage at the annual Black Hat security conference in Las Vegas.

Barnaby was best known for his security research on medical devices.
Jack was one of the world's most prominent "white hat" hackers - those who use their technical skills to find security holes before criminals can exploit them.
