Internet of Vulnerable Things (IoVT): Detecting Vulnerable SOHO Routers

There has been a rampant surge in compromise of consumer grade small scale routers in the last couple of years. Attackers are able to manipulate the Domain Name Space (DNS) settings of these devices hence making them capable of initiating different man-in-the-middle attacks. By this study we aim to explore and comprehend the current state of these attacks. Focusing on the Indian Autonomous System Number (ASN) space, we performed scans over 3 months to successfully find vulnerable routers and extracted the DNS information from these vulnerable routers. In this paper we present the methodology followed for scanning, a detailed analysis report of the information we were able to collect and an insight into the current trends in the attack patterns. We conclude by proposing recommendations for mitigating these attacks.
