改进的同形词攻击分类

Improving Homograph Attack Classification

Tran Phuong Thao

摘要:

视觉同形异义词攻击是一种攻击者通过利用与真实域名相似的伪造域名来欺骗Web用户访问的域名的方式。T. Thao等人(IFIP SEC'19)通过对从基于单个字符的结构相似性指数(SSIM)提取的特征应用常规监督学习算法提出了同形异义词分类。本文旨在提高分类精度相结合的SSIM特征与199个特征提取的N-gram模型和应用先进的集成学习算法。实验结果表明,我们提出的方法可以提高1.81%的准确率,降低2.15%的假阳性率。此外,现有的工作在一些特征上应用了机器学习,但无法解释为什么应用它可以提高准确性。尽管准确性可以提高,但了解地面实况也至关重要。因此,在本文中,我们进行了错误的实证分析,并可以得到我们提出的方法背后的几个发现。

英文摘要:

A visual homograph attack is a way that the attacker deceives the web users about which domain they are visiting by exploiting forged domains that look similar to the genuine domains. T. Thao et al. (IFIP SEC'19) proposed a homograph classification by applying conventional supervised learning algorithms on the features extracted from a single-character-based Structural Similarity Index (SSIM). This paper aims to improve the classification accuracy by combining their SSIM features with 199 features extracted from a N-gram model and applying advanced ensemble learning algorithms. The experimental result showed that our proposed method could enhance even 1.81% of accuracy and reduce 2.15% of false-positive rate. Furthermore, existing work applied machine learning on some features without being able to explain why applying it can improve the accuracy. Even though the accuracy could be improved, understanding the ground-truth is also crucial. Therefore, in this paper, we conducted an error empirical analysis and could obtain several findings behind our proposed approach.
