The internet, one of man’s greatest discoveries, is now literally at our fingertips. Though it is highly developed and talks of a progressive society, there are some downsides too: cyber-crimes that affect the lives of many. It has recently come to light that such issues can also extend into areas of medicine.

Pacemakers, designed and incorporated into the body to assist individuals with weak hearts or irregular heartbeats, could possibly be a target of online attacks due the ease with which they can be meddled with, their high maintenance and government regulations. Of course, this is bad news for fans of the tech-savvy cyberspace.



Why Are Pacemakers Susceptible

Blame it on the prototype! Modern day pacemakers consist of microprocessors, which are the main components performing functions such as taking calculations from the heart, including heartbeat rates, for use by doctors. This data is then stored in a database in a device and can be controlled remotely, in short, a “backdoor” to the computer. It is understood that this product can be tampered and the entryway can be broken into due to its negligible encryption. The answer to why it’s not being updated is as yet unknown.

How Can It Can Be Counteracted

Security measures to improve the construction of pacemakers including, as researchers have suggested, installing jammers, building a stronger firewall, and password protecting the medical device, need to be taken swiftly in order to combat this challenge. Approaching it from a broader angle, experts are beginning to insist on stricter laws and legislation with respect to cybersecurity. Hospitals have been left out of the equation as they are required to comply with the FDA and cannot update any software or malware protection independently.

Director at Center for Cyber and Information Security (CCIS), Sofie Nystrom called this an era of “cyber warfare” and “cyber criminality.” In order to combat this, she is determined to find a solution. Several specialists are in the process of brainstorming ideas and conducting research studies. In the past, Nystrom has been quoted saying, “It’s a situation we don't quite know how to handle.”

Real-life Scenarios

Recently, this year, SINTEF researcher, Marie Moe, addressed a conference in Norway ‘Digital Force for Change’ where the challenges of cybersecurity were brought up. At this time, she shared a personal experience in which she noticed that her pacemaker (which was fitted into her heart after an accident) could potentially be tabbed and the details compromised. “I was shocked to discover that my pacemaker could be connected to the internet. It was then I realized that it’s possible for some computer nerd to hack the system and effectively control my heart. It was a very unpleasant experience.”

Although a relatively newer menace in the world of health, these kind of incidents are not uncommon. For example, in 2014, company Statoil endured a threat when a technician got past the firewall by simply pushing a button that completely stopped production. Hackers can endanger systems and gain a massive amount of private or financial information, making it a foreboding proposition in our near future. Not to forget, any error on their part could be deemed costly, or even fatal.

On a larger scale, what results from a cyberattack on the vulnerable pacemakers is the breach and manipulation of data which can lead to a range of consequences from blackmail to even cardiac arrests in patients.

This reality-check is begging action, and hopefully, on a national and international level, measures will be taken and responsibility endowed in solving what could become a huge peril to the health and existence of mankind.
