Abstract

With advancements in connected technology, the number of ambitious applications involving Internet of Things (IoT) are drastically growing. This increases concerns related to security, scalability, and interoperability of IoT. As the network of connected devices grows, decentralized technologies become inevitable. Within this trend towards decentralization, distributed ledger technology (for instance IOTA) will be a significant driving force. IOTA is an innovative distributed ledger technology targeted towards low power devices, where energy efficiency is a high priority. Public research regarding security threats against IOTA especially denial-of-service (DoS) is essentially non-existent. In this paper we focus on exploring a DoS attack against IOTA. The proposed attack methodology takes advantage of the lack of fees along with the ability to transfer minuscule amounts. By sending many conflicting transactions as it results in a high number of re-attachments. The high number of re-attachments threatens IOTA's suitability for the IoT sphere. The implications of such attack, as well as the future of this issue in terms of the planned removal of the centralized coordinator are discussed.
