Examining the Activities of Cloud-Based Cryptocurrency-Mining Groups
The allure of unauthorized cryptocurrency mining for malicious actors is easy to understand: For less effort than running a full-blown campaign, they can essentially “print money” by using their victims’ resources, at no cost to them other than the work they exert to compromise the systems. A recent trend among malicious actors engaged in cryptocurrency-mining activities has been to focus their efforts on the cloud. While GPU-based mining remains the preferred method for most legitimate cryptocurrency miners because of its higher profitability, the scalability of the cloud allows CPU-based mining to become profitable, especially when attackers manage to compromise a large number of cloud-connected machines. In our research paper “A Floating Battleground: Navigating the Landscape of Cloud-Based Cryptocurrency Mining,” we take a look at the landscape of cloud-based cryptocurrency-mining attacks, focusing on the most prominent groups in this space, their battle for cloud resources, and th...
