192: Button Connected To Nothing
Terry Dunlap, founder and CEO of Tactical Network Solutions, discusses the critical lack of security in Internet of Things (IoT) devices, citing the Mirai botnet, the TrendNet FTC lawsuit, and the St. Jude Medical defibrillator alert as key examples of failure. He explains that common vulnerabilities stem from insecure coding practices, such as buffer overflows and hardcoded keys, often exacerbated by outsourcing firmware development without source code visibility. Dunlap highlights the emergence of standards like UL 2900 and the work of organizations like CableLabs to enforce firmware evaluation, while noting that consumers often remain vulnerable due to poor router configurations and a lack of firmware update support. He advises manufacturers to implement secure coding practices, use source code auditing tools, and encrypt firmware images to reduce the attack surface before devices reach the field.
