It is reported recently that legitimate libraries are repackaged for propagating malware. An in-depth analysis of such potentially-harmful libraries (PhaLibs), however, has never been done before, due to the challenges in identifying those libraries whose code can be unavailable online (e.g., removed from the public repositories, spreading underground, etc.). Particularly, for an iOS app, the library...
In this paper, small data transmission at the detached machine-type-communication (MTC) device in 3GPP LTE environment is investigated. A cell-based dynamic preamble grouping mechanism is proposed to suppress the collision probability in the random access process for small data transmission based on the realistic distribution of MTC devices in each LTE cell. The related signaling messages are discussed...
Mobile malware is rapidly developing, but current anti-virus products in mobile devices still use the signature-based solutions, which usually need a large database and cannot detect malware variants. In this paper, we proposed a behavior-based malware detection system for Windows Mobile platform called WMMD (Windows Mobile Malware Detection system). WMMD uses API interception techniques to dynamic...
