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
Command & Control: Understanding, Denying and Detecting - A review of malware C2 techniques, detection and defences
In this survey, we first briefly review the current state of cyber attacks,
highlighting significant recent changes in how and why such attacks are
performed. We then investigate the mechanics of malware command and control
(C2) establishment: we provide a comprehensive review of the techniques used by
attackers to set up such a channel and to hide its presence from the attacked
parties and the security tools they use. We then switch to the defensive side
of the problem, and review approaches that have been proposed for the detection
and disruption of C2 channels. We also map such techniques to widely-adopted
security controls, emphasizing gaps or limitations (and success stories) in
current best practices.Comment: Work commissioned by CPNI, available at c2report.org. 38 pages.

A Survey of Techniques for Improving Security of GPUs
Graphics processing unit (GPU), although a powerful performance-booster, also
has many security vulnerabilities. Due to these, the GPU can act as a
safe-haven for stealthy malware and the weakest `link' in the security `chain'.
In this paper, we present a survey of techniques for analyzing and improving
GPU security. We classify the works on key attributes to highlight their
similarities and differences. More than informing users and researchers about
GPU security techniques, this survey aims to increase their awareness about GPU
security vulnerabilities and potential countermeasures
