Jack Barnaby, Dead Blackhat

This is what happens when black hats create IRL weapons of death...

Insulin pumps:

At the McAfee FOCUS 11 conference in October 2011 in Las Vegas, while working for McAfee Security, Jack first demonstrated the wireless hacking of insulin pumps, one worn by a diabetic friend and another of the same model on a bench set up for demonstration. Interfacing with the pumps with a high-gain antenna, he obtained complete control of the pumps without any prior knowledge of their serial numbers, up to being able to cause the demonstration pump to repeatedly deliver its maximum dose of 25 units until its entire reservoir of 300 units was depleted, amounting to many times a lethal dose if delivered to a typical patient.

At the RSA Security Conference in San Francisco in February 2012, using a transparent mannequin he demonstrated that he could wirelessly hack the insulin pump from a distance of up to 90 metres using the high-gain antenna.

Pacemakers:

In 2012 Jack demonstrated the ability to assassinate a victim by hacking their pacemaker. This scenario was first explored in fiction on the TV series Homeland. In his blog post "Broken Hearts", Jack wrote that the hack was even easier than portrayed: "TV is so ridiculous! You don't need a serial number!" Jack demonstrated delivering such a deadly electric shock live at the 2012 BreakPoint security conference in Melbourne.

Jack died a week before he was to give a presentation on hacking heart implants at the Black Hat 2013 conference scheduled to be held in Las Vegas. In a June 2013 interview with Vice, Jack outlined his presentation:

Jack was found dead in a San Francisco apartment on 25 July 2013 by his girlfriend. According to the coroner's report, Jack died of an accidental overdose of heroin, cocaine, Benadryl and Xanax. However, his girlfriend claimed he did not do drugs at the time.  He was 35. At the time of his death, he was due to attend a Black Hat Briefings hacking conference in Las Vegas
