Explore the security vulnerabilities of popular children's smartwatches in this conference talk that demonstrates how manufacturers' promises of safety and privacy fall short of reality. Follow along as security researcher Nils Rollshausen takes you through the complete hacking process of one of the most popular children's watches on the market, from gaining initial access to running custom code on the device. Discover critical security flaws that allow attackers to read and write messages, virtually abduct children, and take control of any watch in the system. Learn about the mainstream adoption of these devices, which are now advertised on public transport and sold by major cell providers at premium prices comparable to entry-level Apple watches, while parents are promised peace of mind through safe technology introduction and the ability to call, text, and locate their children. Examine how vendor claims about GDPR compliance, European-made apps, and German cloud servers hold up under scrutiny. Understand the disclosure process, witness questionable security fixes implemented by manufacturers, and explore how the discovered vulnerabilities can be leveraged to build better, more secure solutions for children's wearable technology.
