Researchers from the Swiss Federal Institute of Technology in Zurich and the French National Institute for Research in Computer Science and Control have developed a scheme for protecting implantable medical devices against wireless attacks. The approach relies on using using ultrasound waves to determine the exact distance between a medical device and the wireless reader attempting to communicate with it. The researchers say more than 100,000 Zyxel networking products could be vulnerable to a hardcoded credential vulnerability (CVE-2020-29583) potentially allowing cybercriminal device takeover.
