With the rapid increase in the number of ransomwares recently, the development of real-time strategies for ransomware defense is imperative. To overcome the limitations of traditional ransomware defense techniques, a storage-level data recovery technique was suggested. However, as the technique inefficiently selects data to conserve, it has a negative impact on the lifetime and performance of storage. In this paper, we propose a CNN-based encrypted data detection technique to enhance the accuracy of selecting data to conserve while ensuring complete data recovery. Our experiments show that the proposed technique achieved 93.90% detection accuracy at the storage-level without any high-level information. Furthermore, by changing the loss function and controlling a detection threshold, we attained a false negative rate of nearly 0.
