Statistical Study of Imported APIs by PE Type Malware
Mohamed Belaoued, Smaine Mazouzi · 2014
In this paper we introduce a statistical study which enable us to know which are Windows APIs that are most imported by malware codes. To do that, we have used a given number of infected Portable Executable (PE) files and another number of none infected ones. We used statistical Khi2test to set if an API is likely used by malware or not. We guess that a given work is necessary and important for behavior-based malware detection, especially which use API importations to analyze PE codes. For experimentation purpose, we have used a large set of PE files extracted from known databases to perform our analysis and establish our conclusions.
