Mask Off: Analytic-based Malware Detection By Transfer Learning and Model Personalization
The vulnerability of smartphones to cyberattacks has been a severe concern to
users arising from the integrity of installed applications (\textit{apps}).
Although applications are to provide legitimate and diversified on-the-go
services, harmful and dangerous ones have also uncovered the feasible way to
penetrate smartphones for malicious behaviors. Thorough application analysis is
key to revealing malicious intent and providing more insights into the
application behavior for security risk assessments. Such in-depth analysis
motivates employing deep neural networks (DNNs) for a set of features and
patterns extracted from applications to facilitate detecting potentially
dangerous applications independently. This paper presents an Analytic-based
deep neural network, Android Malware detection (ADAM), that employs a
fine-grained set of features to train feature-specific DNNs to have consensus
on the application labels when their ground truth is unknown. In addition, ADAM
leverages the transfer learning technique to obtain its adjustability to new
applications across smartphones for recycling the pre-trained model(s) and
making them more adaptable by model personalization and federated learning
techniques. This adjustability is also assisted by federated learning guards,
which protect ADAM against poisoning attacks through model analysis. ADAM
relies on a diverse dataset containing more than 153000 applications with over
41000 extracted features for DNNs training. The ADAM's feature-specific DNNs,
on average, achieved more than 98% accuracy, resulting in an outstanding
performance against data manipulation attacks
