Classification for DGA-Based Malicious Domain Names with Deep Learning Architectures

The preemptive defenses against various malware created by domain generation algorithms (DGAs) have traditionally been solved using manually-crafted domain features obtained by heuristic process. However, it is difficult to achieve real-world deployment with most research on detecting DGA-based malicious domain names due to poor performance and time consuming. Based on the recent overwhelming success of deep learning networks in a broad range of applications, this article transfers five advanced learned ImageNet models from Alex Net, VGG, Squeeze Net, Inception, Res Net to classify DGA domains and non-DGA domains, which: (i) is suited to automate feature extraction from raw inputs; (ii) has fast inference speed and good accuracy performance; and (iii) is capable of handling large-scale data. The results show that the proposed approach is effective and efficient.
