. For instance, if a technically competent individual with wrong intentions remotely takes control of a patient’s insulin pump, there can be catastrophic consequences, such as wrong insulin dose delivery, stalling the insulin pump, creating hypoglycemic episodes or muting the safety beep features in the insulin pump. An attacker with such access can launch extortionist viruses in the hospital system or replace patient images," says. Pacemakers, in particular, can be controlled by devices that can increase or decrease heart rates to dangerous levels. Internet of Medical Things (IoMT) is designed to broaden the attack surface for healthcare organisations.Sophisticated and unsecureElaborating more on the topic, Dr Ravi Sankar Erukulapati, Senior Endocrinologist, Apollo, says, "There are many types of insulin pumps. "Recently, a medical company discovered vulnerabilities in common infusion pumps that are intended for the metered injection of drugs into a patient’s organisms. "Any unauthorised person with special technical skills and equipment can connect wirelessly to a nearby insulin pump to change settings and control delivery of the hormone," it said. While such functions improve patient comfort and usability of the device, they have their own downside. The basic ones are simple, but some sophisticated insulin pumps have higher functions such as the ability to control using a remote control.So also, it’s only natural that closer home, the Modi government recently issued an alert about insulin pumps and pacemakers being vulnerable to hackers who can connect to them and control delivery of the hormone into a patient’s body."Electronic devices can be programmed like the remote of a TV.

Homeland’s premise, however, was built around a real life story — of former US Vice President Dick Cheney, whose pacemaker’s wireless capabilities were disabled to thwart possible assassination attempts.In addition, last year, Abbott had recalled over five lakh pacemakers. It is expected that by 2020, almost 650 million IoMT devices will be used."In view of such risks, it is of paramount importance that insulin-pump manufacturers, or for that matter all medical device manufacturers, take all necessary precautions to avoid such misuse of the devices.Cyber nightmares closing inGiven the increasing number of healthcare equipment — from cardiac monitors to glucometers — being equipped with wireless connectivity and sensors, the number of potential exposure points only increase, giving way to black-hat hackers. And this, hackers can kill patients. Quite the hack, you’d say?‘Medjacking’, or medical device hijacking, is a real cyber security threat and to healthcare systems.These insulin pumps are designed to communicate using wireless radio frequency (RF) with other devices such as blood glucose meters, glucose sensor transmitters and certain CareLink USB devices. They take over the latter’s life by taking charge of the medical equipment they wear or use. So when an internet-connected device is implanted in body to help maintain heart rate or regulate the insulin in bloodstream, security lapses can literally be hazardous to your health.Virtual dangersFictional plots aside, can such horrifying scenarios really play out in real life too? Yes they can, say experts. Similarly, insulin pumps can be controlled and levels of insulin can be modified, which can lead to coma or death," affirms Dr Sunil Kapoor, senior Consultant Cardiologist, Apollo Hospitals.

The idea had originated in the popular TV show Homeland way back in 2012, where terrorists were provided a serial number to hack the pacemaker of Vice-President William Walden.Digital world has become a common place to read about the most secure sites and the most confidential data falling prey to hackers."Given the gravity of the situation, the Central Drug Standard Control Organisation’s (CDSCO) in Delhi had also sent out an alert sometime in May this year.A security flaw in a pacemaker by the US medical device-maker Medtronic makes it possible for hackers to take control of the device and deliver malware to the computers implanted in someone’s chest.Mukesh Choudhary, founder & CEO, CyberopsInfosec, also concurs that hackers can find vulnerabilities in almost any system 3/8" saw chain Suppliers and gain control over the device and its controls. After all, technology is a double-edged sword," adds Dr Ravi, as he signs off. About 465,000 pacemakers were recently implicated in a major hacking risk. But can hackers find their way into hacking medical instruments like pacemakers, insulin pumps and more ? We find outIt looks like a perfect movie script: Cyber criminals are assigned to assassinate high profile personalities using pacemakers. Additionally, in 2016, Johnson & Johnson (J&J) divulged to patients the security vulnerability in an insulin pump that could be exploited by hackers to overdose diabetic patients with insulin.
