Internet of Things offers many exciting new applications ranging from security & surveillance, smart agriculture, smart construction, rescue during natural disasters. However, IoT nodes and gateways are often unsecured and do not have adequate compute power to employ sophisticated security mechanisms. These nodes become attractive targets for malicious bot writers to exploit. Botnets are being employed for attacks like distributed denial of service, information theft, spam, data espionage, and phishing. The devastating impact caused by botnet based attacks necessitates the study of defending Internet of Things against botnets. Our work seeks to detect IoT nodes being infected with botnets.
