Recently, various devices, such as automobiles, and medical and industrial systems, have been connected to the Internet, and this network is referred to as the Internet of Things (IoT). IoT devices that do not have an authentication function risk unauthorized access. In addition, there is a high possibility that the IoTs may be used as a springboard for Distributed Denial of Service (DDoS) attacks. Moreover, once the installed equipment is no longer used, it is difficult to notice attacks, such as illegal operation by a malicious user, so that the risk increases further. These unmanaged devices are referred to as stray IoT devices. In this paper, we describe the status of stray IoT devices in Japan and report that we investigated the relationship of regional characteristics between the number of stray IoT devices by prefecture and other data by prefecture by conducting a correlation analysis. As a result, a significant correlation between the phishing damage rate and the number of stray IoT devices was found to exist. These results are thought to be useful for planning countermeasures against stray IoT devices.
