A Monte Carlo method for the spread of mobile malware
A new model for the spread of mobile malware based on proximity (i.e.
Bluetooth, ad-hoc WiFi or NFC) is introduced. The spread of malware is analyzed
using a Monte Carlo method and the results of the simulation are compared with
those from mean field theory.Comment: 11 pages, 2 figure

Modelling the Spread of Botnet Malware in IoT-Based Wireless Sensor Networks
The propagation approach of a botnet largely dictates its formation, establishing a foundation of bots for future exploitation. The chosen propagation method determines the attack surface, and consequently, the degree of network penetration, as well as the overall size and the eventual attack potency. It is therefore essential to understand propagation behaviours and influential factors in order to better secure vulnerable systems. Whilst botnet propagation is generally well-studied, newer technologies like IoT have unique characteristics which are yet to be thoroughly explored. In this paper, we apply the principles of epidemic modelling to IoT networks consisting of wireless sensor nodes. We build IoT-SIS, a novel propagation model which considers the impact of IoT-specific characteristics like limited processing power, energy restrictions, and node density on the formation of a botnet. Focusing on worm-based propagation, this model is used to explore the dynamics of spread using numerical simulations and the Monte Carlo method, and to discuss the real-life implications of our findings
Malware "Ecology" Viewed as Ecological Succession: Historical Trends and Future Prospects
The development and evolution of malware including computer viruses, worms,
and trojan horses, is shown to be closely analogous to the process of community
succession long recognized in ecology. In particular, both changes in the
overall environment by external disturbances, as well as, feedback effects from
malware competition and antivirus coevolution have driven community succession
and the development of different types of malware with varying modes of
transmission and adaptability.Comment: 13 pages, 3 figure
Android Applications Security
The use of smartphones worldwide is growing very fast and also the malicious attacks have increased. The mobile security applications development keeps the pace with this trend. The paper presents the vulnerabilities of mobile applications. The Android applications and devices are analyzed through the security perspective. The usage of restricted API is also presented. The paper also focuses on how users can prevent these malicious attacks and propose some prevention measures, including the architecture of a mobile security system for Android devices.Mobile Application, Security, Malware, Android, Permissions
A Novel Approach to Trojan Horse Detection in Mobile Phones Messaging and Bluetooth Services
A method to detect Trojan horses in messaging and Bluetooth in mobile phones by means of monitoring the events produced by the infections is presented in this paper. The structure of the detection approach is split into two modules: the first is the Monitoring module which controls connection requests and sent/received files, and the second is the Graphical User module which shows messages and, under suspicious situations, reports the user about a possible malware. Prototypes have been implemented on different mobile operating systems to test its feasibility on real cellphone malware. Experimental results are shown to be promising since this approach effectively detects various known malwareMinisterio de Ciencia e Innovación TIN2009-14378-C02-0
The Paradox of Choice: Investigating Selection Strategies for Android Malware Datasets Using a Machine-learning Approach
The increase in the number of mobile devices that use the Android operating system has attracted the attention of cybercriminals who want to disrupt or gain unauthorized access to them through malware infections. To prevent such malware, cybersecurity experts and researchers require datasets of malware samples that most available antivirus software programs cannot detect. However, researchers have infrequently discussed how to identify evolving Android malware characteristics from different sources. In this paper, we analyze a wide variety of Android malware datasets to determine more discriminative features such as permissions and intents. We then apply machine-learning techniques on collected samples of different datasets based on the acquired features’ similarity. We perform random sampling on each cluster of collected datasets to check the antivirus software’s capability to detect the sample. We also discuss some common pitfalls in selecting datasets. Our findings benefit firms by acting as an exhaustive source of information about leading Android malware datasets
