Remember, this is a warning, no one has been caught doing this yet. Wireless devices are making the world much more connected, and at times I believe safer. If your heart is bad, and this device can help you survive and get word to rescuers that you are in trouble, being hacked in the risk I will take. The key is to recognize the risks, and be aware of them. The makers also have to understand the risks, if they do not have the ability to secure the devices.
