SAN FRANCISCO (AP) — A prominent hacker who discovered a way to have ATM machines spit out cash and was set to deliver a talk about hacking pacemakers and other wireless implantable medical devices has died in San Francisco.

San Francisco Deputy Coroner Kris Barbrich says Barnaby Jack died on Thursday. The Medical Examiner's Office is still investigating the cause of death.

Jack, who was in his mid-30s, was scheduled to speak on Aug. 1 at the Black Hat security conference in Las Vegas.

He made headlines in 2010 when he demonstrated his ability to hack stand-alone ATMs. Jack was able to hack them in two ways — remotely and using physical keys that come with the machines.
