Security experts agree that it’s only a matter of time before smartphones become the smart person’s murder weapon of choice.

Last October at Melbourne’s grand Intercontinental Hotel scores of technophiles watched a researcher for IOActive, a Seattle-based computer-security firm, demonstrate an ingenious new way to kill someone—a method that one can imagine providing a sensational plot twist in an episode of Homeland.

The IOActive researcher, a man named Barnaby Jack, was so worried about the implications of his work that he intentionally obscured many of the details in his presentation. As a further precaution, he asked the attendees not to take any pictures—a tough request in a crowd full of smartphones and laptops.

Jack’s work concerned pacemakers and implantable cardioverter-defibrillators (I.C.D.’s). More than three million American heart patients carry around these small, computerized devices, which monitor their heartbeat and deliver jolts of electricity to stabilize it when needed. To check and adjust these devices, many doctors use wand-like wireless programmers that they wave a few inches above patients’ chests—a straightforward and seemingly safe procedure. But now, with a custom-built transmitter, Jack had discovered how to signal an I.C.D. from 30 feet away. It reacted as if the signal were in fact coming from the manufacturer’s official I.C.D. programmer. Instructed by the counterfeit signal, the I.C.D. suddenly spat out 830 volts—an instantly lethal zap. Had the device been connected to an actual human heart, the fatal episode would likely have been blamed on a malfunction.

This is a guy who had demonstrated the year before how he could wirelessly direct an implantable insulin pump to deliver a lethal dose. The year before that, he hacked an ATM to make it spray out bills like a slot machine. But trouble-making is what he’s paid to do at IOActive, and in that role he has developed a particular respect for the looming power of smartphones. Terrorists have already used cell phones to kill people in the crudest possible way: detonating explosives in Iraq and Afghanistan. But smartphones bring a new elegance to the endeavor and will bring new possibilities for mayhem into the most mundane areas of life.

A dozen ventures are developing smartphone apps for medical devices: pacemakers, defibrillators, cochlear implants, insulin pumps, cardiovascular monitors, artificial pancreases, and all the other electronic marvels doctors now are inserting into human bodies.

Smartphones can relay patients’ data to hospital computers in a continuous stream. Doctors can alter treatment regimens remotely, instead of making patients come in for a visit. If something goes wrong, medical professionals can be alerted immediately and the devices can be rapidly adjusted over the air.

The day is not far off, Jack says, when the manipulation of medical devices, for which he had needed to build special equipment, will be done routinely and remotely by punching keys on a smartphone. :shifty:

This is scary for someone who wears a medical device, for sure. You never know these days.

i'm not sure i'd rely on my smartphone for any kind of life saving treatment! but the hacking of the pacemaker or insulin pump with the custom built transmitter is pretty scary for those people with the devices implanted

I'm not surprised, most modern smartphones are as powerful or more-so than PC's were only a few years ago and they don't linger that far behind either, with that comes many more opportunities to manipulate the technology that is no longer extremely limited.

Am I the only one wondering why it's even possible to make an ICD deliver an 830v (lethal) discharge? Why does this device even have a power source capable of delivering such a charge? On top of that, are there no fail-safes or circuit-breakers? /boggle

This guy's hack does point of possible scary scenarios in the future, but I'm just left wondering why it's even remotely possible to begin with.
