Malware detection techniques for mobile devices
Mobile devices have become very popular nowadays, due to its portability and
high performance, a mobile device became a must device for persons using
information and communication technologies. In addition to hardware rapid
evolution, mobile applications are also increasing in their complexity and
performance to cover most needs of their users. Both software and hardware
design focused on increasing performance and the working hours of a mobile
device. Different mobile operating systems are being used today with different
platforms and different market shares. Like all information systems, mobile
systems are prone to malware attacks. Due to the personality feature of mobile
devices, malware detection is very important and is a must tool in each device
to protect private data and mitigate attacks. In this paper, analysis of
different malware detection techniques used for mobile operating systems is
provides. The focus of the analysis will be on the to two competing mobile
operating systems - Android and iOS. Finally, an assessment of each technique
and a summary of its advantages and disadvantages is provided. The aim of the
work is to establish a basis for developing a mobile malware detection tool
based on user profiling.Comment: 11 pages, 6 figure
Android Malware Family Classification Based on Resource Consumption over Time
The vast majority of today's mobile malware targets Android devices. This has
pushed the research effort in Android malware analysis in the last years. An
important task of malware analysis is the classification of malware samples
into known families. Static malware analysis is known to fall short against
techniques that change static characteristics of the malware (e.g. code
obfuscation), while dynamic analysis has proven effective against such
techniques. To the best of our knowledge, the most notable work on Android
malware family classification purely based on dynamic analysis is DroidScribe.
With respect to DroidScribe, our approach is easier to reproduce. Our
methodology only employs publicly available tools, does not require any
modification to the emulated environment or Android OS, and can collect data
from physical devices. The latter is a key factor, since modern mobile malware
can detect the emulated environment and hide their malicious behavior. Our
approach relies on resource consumption metrics available from the proc file
system. Features are extracted through detrended fluctuation analysis and
correlation. Finally, a SVM is employed to classify malware into families. We
provide an experimental evaluation on malware samples from the Drebin dataset,
where we obtain a classification accuracy of 82%, proving that our methodology
achieves an accuracy comparable to that of DroidScribe. Furthermore, we make
the software we developed publicly available, to ease the reproducibility of
our results.Comment: Extended Versio
