Feed-Forward Deep Neural Network (FFDNN)-Based Deep Features for Static Malware Detection
Autor: Priyanka Singh, Samir Kumar Borgohain, Achintya Kumar Sarkar, Jayendra Kumar, Lakhan Dev Sharma
Publikováno v: International Journal of Intelligent Systems.
The portable executable header (PEH) information is commonly used as a feature for malware detection systems to train and validate machine learning (ML) or deep learning (DL) classifiers. We propose to extract the deep features from the PEH informati
