Deadly Virus: What happens when a hacker takes over the pacemaker?

A security researcher was able to take control of pacemakers with wireless connection and re-programmed so that they can kill the patient
Wireless interface enables control the device
Are computer viruses can damage pacemakers and resuscitation devices? Apparently so, if you believe the security researcher published today (Thursday) at the Melbourne hackers. Researcher, Barnaby Jack, warns that the most obvious scenario of infecting virus pacemaker is vulnerable person.
Researcher demonstrated during the conference how he takes over the automatic implanted defibrillator - a device implanted in patients with a risk of sudden death from cardiac arrest or arrhythmias. Then, he sent a current of 830 volts through the device. This can even take control of these devices is wireless interface installed new ones, designed to allow the operation without the need to remove them, and call them data without direct access.
According to Jack, the break was very easy, because the devices not secure, beyond the need to put a serial number and product number. And these, he says, very easy to find, as then you can program the device again. At the same time, Jack did not clarify which models it, and says he hopes to work with the manufacturers whose products managed to break to prevent people from doing this in the future.
Just a year ago, Barnaby Jack demonstrated how he takes over the wireless insulin pump Medtronic, and able to provide the patient a fatal overdose of insulin. Whereas two years ago, took the researcher on two ATMs and making them "green" their the bills.
