Through a comprehensive analysis of the attack way, composition structure, and attack code of malicious documents, we present a detecting method based on the mathematical statistics and vector computation, and make targeted improvements for a typical deformation means. We tested 119 documents using this algorithm, and the results show that, compared with conventional detection software, this algorithm detects a malicious document with low fail-to-report rate and low false alarm rate.
Key words： malicious file; mathematical statistics; vector space
