The dangers of the digital age

Abstract

Every year, millions of CT and MRI scans are done all over the world. The scanners are generally managed on an internal network, with a central server receiving and storing the images in readiness for analysis by the radiology department. However, networks that are not connected to the internet are still vulnerable to attack. A new, non-peer-reviewed paper from Israel shows the ease with which an external attacker could obtain and tamper with patient scans and trick experts into concluding that cancer is present or absent, when in fact the reverse is true.
