摘要: 机器学习已经广泛应用于恶意代码检测中，并在恶意代码检测产品中发挥重要作用。构建针对恶意代码检测机器学习模型的对抗样本，是发掘恶意代码检测模型缺陷，评估和完善恶意代码检测系统的关键。该文提出一种基于遗传算法的恶意代码对抗样本生成方法，生成的样本在有效对抗基于机器学习的恶意代码检测模型的同时，确保了恶意代码样本的可执行和恶意行为的一致性，有效提升了生成对抗样本的真实性和模型对抗评估的准确性。实验表明，该文提出的对抗样本生成方法使MalConv恶意代码检测模型的检测准确率下降了14.65%；并可直接对VirusTotal中4款基于机器学习的恶意代码检测商用引擎形成有效的干扰，其中，Cylance的检测准确率只有53.55%。Abstract: Machine learning is widely used in malicious code detection and plays an important role in malicious code detection products. Constructing adversarial samples for malicious code detection machine learning models is the key to discovering defects in malicious code detection models, evaluating and improving malicious code detection systems. This paper proposes a method for generating malicious code adversarial samples based on genetic algorithms. The generated samples combat effectively the malicious code detection model based on machine learning, while ensuring the consistency of the executable and malicious behavior of malicious code samples, and improving effectively the authenticity of the generated adversarial samples and the accuracy of the model adversarial evaluation are presented. The experiments show that the proposed method of generating adversarial samples reduces the detection accuracy of the MalConv malicious code detection model by 14.65%, and can directly interfere with four commercial machine-based malicious code detection engines in VirusTotal. Among them, the accuracy rate of Cylance detection is only 53.55%.
