Abstract
Malicious PDF files recently considered one of the most dangerous threats to the system security. The flexible code-bearing vector of the PDF format enables to attacker to carry out malicious code on the computer system for user exploitation. Many solutions have been developed by security agents for the safety of user’s system, but still inadequate. In this paper, we propose a method for malicious PDF file detection via machine learning approach. The proposed method extract features from PDF file structure and embedded JavaScript code that leverage on advanced parsing mechanism. Instead of looking for the specific attack inside the content of PDF i.e. quite complex procedure, we extract features that are often used for attacks. Moreover, we present the experimental evidence for the choice of learning algorithm to provide the remarkably high accuracy as compared to other existing methods.
