From medical errors to superbugs, the risks during a spell in hospital can be daunting. The prospect of the medical device you are hooked being compromised by hackers is just another worry to add to the list. Unfortunately, this is a legitimate concern, say experts. In recent years, a wide range of vulnerabilities in connected medical devices have been uncovered. As more healthcare equipment — from cardiac monitors to glucometers — is equipped with wireless connectivity and sensors, potential exposure points increase, leaving doors open to cyber criminals.
