Abstract: In the past few years, the prosperity of the smart device market has developed in a skyrocketing pace due to the rapid development of technology, productivity, as well as the fast expanding scale of IoT (Internet of things). IoT is not only an important part in cyberspace, but also a critical point to promote the development of intelligent technology .However, the security issue of IoT device cant be ignored. Recently, there have been several campaigns made by attackers who managed to use Botnet made by IoT devices, resulted from users ignorance of security and the potential security risks of the device itself. This article is based on the DDoS(distributed denial of service) attacks against East Coast of US DNS infrastructure, aiming at getting readers attention to IoT security. Many IoT devices have security risks which could be exploited by malicious code, therefore, how to use them properly with our privacy and security secure is one of our current priorities we should care about.
