  • A medical device hijack (also called medjack) is a type of cyber attack. The weakness they target are the medical devices of a hospital. This was covered extensively in the press in 2015 and in 2016. Medical device hijacking received additional attention in 2017. This was both a function of an increase in identified attacks globally and research released early in the year. These attacks endanger patients by allowing hackers to alter the functionality of critical devices such as implants, exposing a patient's medical history, and potentially granting access to the prescription infrastructure of many institutions for illicit activities. MEDJACK.3 seems to have additional sophistication and is designed to not reveal itself as it searches for older, more vulnerable operating systems only found embedded within medical devices. Further, it has the ability to hide from sandboxes and other defense tools until it is in a safe (non-VM) environment. There was considerable discussion and debate on this topic at the RSA 2017 event during a special session on MEDJACK.3. Debate ensued between various medical device suppliers, hospital executives in the audience and some of the vendors over ownership of the financial responsibility to remediate the massive installed base of vulnerable medical device equipment. Further, notwithstanding this discussion, FDA guidance, while well intended, may not go far enough to remediate the problem. Mandatory legislation as part of new national cyber security policy may be required to address the threat of medical device hijacking, other sophisticated attacker tools that are used in hospitals, and the new variants of ransomware which seem targeted to hospitals.
