(eng): One of the current challenges in network intrusion detection research is the malware communicating over HTTPS protocol. Usually the task is to detect infected end-nodes with this type of malware by monitoring network traffc. The challenge lies in a very limited number of weak features that can be extracted from the network traffc capture of encrypted HTTP communication. This paper suggests a novel fingerprinting method that addresses this\nproblem by building a higher-level end-node representation on top of the weak features. Conducted large-scale experiments on real network data show superior performance of the proposed method over the state-of-the-art solution in terms of both a lower number of produced false alarms (precision) and a higher number of detected infections (recall).
