"IoT device vulnerabilities are especially dangerous as they can facilitate sensitive data breaches and lead to physical danger, such as industrial equipment malfunction, medical device defects, or a home security system breach," wrote Merritt Maxim, vice president, research director, and Elsa Pikulik, researcher, Forrester, in the State of IoT Security Report 2021. [1] " In 2020, IoT devices were the second most common vector for an external breach and technology leaders rank security issues as a top concern plaguing or hindering IoT deployments." IoT Security Vulnerabilities – BrakTooth Discovery Recently, researchers at Singapore University of Technology and Design (SUTD) discovered a group of vulnerabilities, they named BrakTooth, in commercial Bluetooth chipsets that impact billions of end-user devices. The SUTD research was funded with a grant from Keysight.
