摘要:

检测感染恶意软件的计算机和基于加密HTTPS流量检测恶意Web域是一个具有挑战性的问题,因为只有地址、时间戳和数据量是可观察的。检测问题是耦合的,因为受感染的客户端往往与恶意域交互。可以大规模收集流量数据,并且可以使用防病毒工具来识别受感染的客户端。相比之下,域必须在取证分析后单独标记。我们探索基于水闸网络的迁移学习;这允许检测模型相互引导。在一个大规模的实验研究中,我们发现,该模型优于已知的参考模型,并检测以前未知的恶意软件,以前未知的恶意软件家族,以前未知的恶意域。

英文摘要:

Detection of malware-infected computers and detection of malicious web domains based on their encrypted HTTPS traffic are challenging problems, because only addresses, timestamps, and data volumes are observable. The detection problems are coupled, because infected clients tend to interact with malicious domains. Traffic data can be collected at a large scale, and antivirus tools can be used to identify infected clients in retrospect. Domains, by contrast, have to be labeled individually after forensic analysis. We explore transfer learning based on sluice networks; this allows the detection models to bootstrap each other. In a large-scale experimental study, we find that the model outperforms known reference models and detects previously unknown malware, previously unknown malware families, and previously unknown malicious domains.
