MalRec: A Blockchain-based Malware Recovery Framework for Internet of Things

IoT devices have been considered an attractive target for malware (e.g., botnets) due to their low computational resources and lack of security measures. The literature focuses on detecting malware, but less attention is given to recovery solutions. In addition, with the development of data processing regulations in different countries, a need for transparent recovery systems that can help organizations present their due diligence arises. This work proposes a blockchain-based backup policy enforcement framework for IoT where an organization can formalize backup policies and enforce them. We have run our solution under extensive tests that show that it can be deployed in real-life IoT environments, despite the limited computational resources of IoT devices.
