An autopsy has concluded that elite hacker Barnaby Jack died as a result of an accidental drug overdose.

Jack was found dead at home in San Francisco last July. He was slated to give a talk at the Black Hat conference in Las Vegas and was expected to discuss hacking medical implants.

An autopsy concluded that Jack died of a multi-drug overdose. Found in his system was a mix of heroin and cocaine as well as prescription drugs – specifically, diphenhydramine (Benadryl) and alprazolam (Xanax).
