基于机器学习恶意软件检测器的标签翻转中毒攻击分析

Analysis of Label-Flip Poisoning Attack on Machine Learning Based Malware Detector

Kshitiz Aryal, Maanak Gupta, Mahmoud Abdelsalam

摘要:

随着机器学习(ML)在不同领域应用的增加,欺骗这些模型的动机比以往任何时候都要多。由于数据是ML算法的核心支柱,攻击者将他们的兴趣转向污染训练数据。随着开放设计原则、联邦学习和众包等最新研究主题的兴起,数据可信度面临更高的风险。由于机器学习模型依赖于不同的利益相关者来获取数据,因此没有可靠的自动化机制来验证来自每个来源的数据的准确性。恶意软件检测是艰巨的,由于其恶意的性质,加上变形和多态性的能力,在不断发展的样本。ML已被证明可以解决零日恶意软件检测问题,这是传统的基于签名的方法无法解决的问题。恶意软件训练数据的中毒可以允许恶意软件文件不被基于ML的恶意软件检测器检测到,从而帮助攻击者实现其恶意目标。恶意软件检测领域中的数据投毒威胁的可行性分析仍然缺乏。我们的工作将集中在两个主要部分:训练基于ML的恶意软件检测器和中毒的训练数据使用标签中毒的方法。我们将分析不同机器学习模型对不同中毒数据量的数据投毒的鲁棒性。

英文摘要:

With the increase in machine learning (ML) applications in different domains, incentives for deceiving these models have reached more than ever. As data is the core backbone of ML algorithms, attackers shifted their interest toward polluting the training data. Data credibility is at even higher risk with the rise of state-of-art research topics like open design principles, federated learning, and crowd-sourcing. Since the machine learning model depends on different stakeholders for obtaining data, there are no reliable automated mechanisms to verify the veracity of data from each source. Malware detection is arduous due to its malicious nature with the addition of metamorphic and polymorphic ability in the evolving samples. ML has proven to solve the zero-day malware detection problem, which is unresolved by traditional signature-based approaches. The poisoning of malware training data can allow the malware files to go undetected by the ML-based malware detectors, helping the attackers to fulfill their malicious goals. A feasibility analysis of the data poisoning threat in the malware detection domain is still lacking. Our work will focus on two major sections: training ML-based malware detectors and poisoning the training data using the label-poisoning approach. We will analyze the robustness of different machine learning models against data poisoning with varying volumes of poisoning data.
