| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | IoT devices such as routers and webcams have dynamic DNS (DDNS) functions as one of the methods to remotely manage devices. While DDNS enhances the convenience of remote management, it also poses risks of making it easier for attackers to access to the IoT devices. Therefore, it is necessary to be careful about the secure implementation and use of DDNS functions. However, to our knowledge, there has been to no research on the use of DDNS functions in IoT devices. In this study, we conducted a survey of DDNS functions in IoT devices sold in Japan in order to clarify the usage status and risks of DDNS functions in IoT devices. As a result, we found a vulnerability in the implementation of the DDNS function in a specific vendor's router, which is used in more than one million units worldwide, and an attack method that allows a malicious third party to steal the router's authentication information. In this paper, in addition to the results of these investigations, we discuss the actual situation of vulnerability exploitation based on long-term tracking of DDNS domains, and present a policy for the secure implementation and use of DDNS functions in IoT devices. | |
