Android mobile devices are a prime target for a huge
number of cyber-criminals as they aim to create malware for
disrupting and damaging the servers, clients, or networks.
Android malware are in the form of malicious apps, that get
downloaded on mobile devices via the Play Store or third-party
app markets. Such malicious apps pose serious threats like system
damage, information leakage, financial loss to user, etc. Thus,
predicting which apps contain malicious behavior will help in
preventing malware attacks on mobile devices. Identifying
Android malware has become a major challenge because of the
ever-increasing number of permissions that applications ask for,
to enhance the experience of the users. And most of the times,
permissions and other features defined in normal and malicious
apps are generally the same. In this paper, we aim to detect
Android malware using machine learning, deep learning, and
natural language processing techniques. To delve into the
problem, we use the Android manifest files which provide us with
features like permissions which become the basis for detecting
Android malware. We have used the concept of information value
for ranking permissions. Further, we have proposed a
consensus-based blockchain framework for making more
concrete predictions as blockchain have high reliability and low
cost. The experimental results demonstrate that the proposed
model gives the detection accuracy of 95.44% with the Random
Forest classifier. This accuracy is achieved with top 45
permissions ranked according to Information Value.
