In-browser cryptojacking malware has gained significant popularity with easy-to-use scripts distributed by the service providers. Coinhive was a pioneer service provider, but it discontinued its service in March 2019. However, cryptojacking malware did not stop, rather it evolved. One of the new victim platforms for cryptojacking malware attacks is IoT devices due to their weak security measures. Although IoT devices are resource-constrained and not profitable individually for attackers, the attackers utilize techniques like botnets to take control of the IoT devices at scale and equip them to perform cryptocurrency mining on behalf of the attacker. For example, a Mirai-inspired LIQUOR IoT botnet started to mine Monero on its victims’ devices as a side profit. In this study, we first design a cryptojacking detection system based on IoT network traffic features. The network traffic data have the advantage of not requiring to program or modify the devices to collect. We experimentally adjusted the best parameters to obtain the optimum detection system. Then, we designed 12 novel experiment scenarios to evaluate various attacker behaviors and compromised network settings. For these experiments, we set up a safe environment to collect malicious and benign datasets. To the best of our knowledge, no prior work investigated the impact of cryptojacking malware on IoT devices and compromised smart home networks, which is heterogeneous in its nature. In this talk, you will find the details of 1) setup environment, 2) malicious data collection, 3) benign data collection, 4) initial data analysis, and 5) final analysis of the results as well as the challenges we encountered during all these experiments.
