WTF. That's pretty low, hacking someone's defibrillator.
There has never been a documented malicious attack on someone's implantable cardiac defibrillator. A spokesperson from Medtronic said that the devices, which had carried such telemetry for 30 years, have never experienced any reported hacking problems.
So, kind of makes you wonder just how bored these researchers were.
Researcher 1: "Dude... let's see if we can hack a debrillator!"
Other researchers give Researcher 1 very, very odd looks.
Researcher 1: "... It could happen. Does anyone else have any better ideas, or for that matter, any ideas at all?"
Other researchers, in fact, do not.
