Security and Privacy Analyses of Internet of Things Children's Toys

This paper investigates the security and privacy of Internet-connected children's smart toys through case studies of three commercially available products. We conduct network and application vulnerability analyses of each toy using static and dynamic analysis techniques, including application binary decompilation and network monitoring. We discover several publicly undisclosed vulnerabilities that violate the Children's Online Privacy Protection Rule as well as the toys' individual privacy policies. These vulnerabilities, especially security flaws in network communications with first-party servers, are indicative of a disconnect between many Internet of Things toy developers and security and privacy best practices despite increased attention to Internet-connected toy hacking risks.
