使用CNN检测恶意PDF

Detecting malicious PDF using CNN

Tel Aviv University(特拉维夫大学)

Raphael Fettaya, Yishay Mansour

摘要:

恶意PDF文件是计算机安全的最大威胁之一。为了检测它们,已经使用手写签名或基于手动特征提取的机器学习进行了重要的研究。这些方法都很耗时,需要大量的先验知识,并且必须根据每个新发现的漏洞更新功能列表。在这项工作中,我们提出了一种新的算法,该算法使用卷积神经网络(CNN)的字节级的文件,没有任何手工制作的功能。我们表明,使用一个数据集的90000个文件在线下载,我们的方法保持了很高的检测率(94%)的PDF恶意软件,甚至检测到新的恶意文件,仍然未被大多数反病毒软件检测到。使用我们的CNN网络自动生成的特征,并应用聚类算法,我们还获得了反病毒标签和所得聚类之间的高度相似性。

英文摘要:

Malicious PDF files represent one of the biggest threats to computer security. To detect them, significant research has been done using handwritten signatures or machine learning based on manual feature extraction. Those approaches are both time-consuming, require significant prior knowledge and the list of features has to be updated with each newly discovered vulnerability. In this work, we propose a novel algorithm that uses an ensemble of Convolutional Neural Network (CNN) on the byte level of the file, without any handcrafted features. We show, using a data set of 90000 files downloadable online, that our approach maintains a high detection rate (94%) of PDF malware and even detects new malicious files, still undetected by most antiviruses. Using automatically generated features from our CNN network, and applying a clustering algorithm, we also obtain high similarity between the antiviruses' labels and the resulting clusters.
