Identifying IoT Devices with SMTP

In this paper, a novel method is proposed from the perspective of spam to detect whether a sender of the mail is an IoT device. How to prevent cyber-attacks has always been an important research topic in this field. Malicious attackers will hide their identifications when they launch attacks so that defenders cannot catch them. Thus from our method, using this information effectively in security research field is useful for preventing malicious behaviors in the future. The security problems of the increment of the Internet of Things (IoT) will come to the forefront. We utilize this method to identify IoT devices effectively.
