A Dynamic Taint Forensic Analysis Tool For Android Apps, Zhen Xu Jan 2017

A Dynamic Taint Forensic Analysis Tool For Android Apps, Zhen Xu

Graduate Theses and Dissertations

Mobile digital forensic faces numerous problems including a huge amount of data, growing amount of applications and usage of encryption or obfuscation. As a result, data of interest is hard to locate. The traditional method uses predefined pattern searching algorithm. Such technique can dig out much information but cannot find information embedded with normal data such as a barcode in an image or encryption. This project intends to develop a tool which facilitates the investigation process by answering what information could exist in a certain file. With the assistance, the investigator can focus on the content of some interesting files ...


Man-Machine Partial Program Analysis For Malware Detection, Thomas Norman Deering Jan 2015

Man-Machine Partial Program Analysis For Malware Detection, Thomas Norman Deering

Graduate Theses and Dissertations

With the meteoric rise in popularity of the Android platform, there is an urgent need to combat the accompanying proliferation of malware. Existing work addresses the area of consumer malware detection, but cannot detect novel, sophisticated, domain-specific malware that is targeted specifically at one aspect of an organization (eg. ground operations of the US Military). Adversaries can exploit domain knowledge to camoflauge malice within the legitimate behaviors of an app and behind a domain-specific trigger, rendering traditional approaches such as signature-matching, machine learning, and dynamic monitoring ineffective. Manual code inspections are also inadequate, scaling poorly and introducing human error. Yet ...


Droidspotter: A Forensic Tool For Android Location Data Collection And Analysis, Jeffrey Alan Kramer Jan 2013

Droidspotter: A Forensic Tool For Android Location Data Collection And Analysis, Jeffrey Alan Kramer

Graduate Theses and Dissertations

Since the surge in popularity of Android smartphones, creating Android applications and using location data in these applications have soared. Due to how quickly Android applications are being created, it is difficult for companies who have created forensics tools to keep updating their programs in a timely manner for investigators to use. This has created a need for a forensics tool which allows forensic investigators to analyze a new Android application themselves since, in most cases, criminal investigations are a time sensitive matter. The purpose of this research is to introduce a prototype for a tool which would allow investigators ...


A Location-Aware Architecture Supporting Intelligent Real-Time Mobile Applications, Sean J. Barbeau Jan 2012

A Location-Aware Architecture Supporting Intelligent Real-Time Mobile Applications, Sean J. Barbeau

Graduate Theses and Dissertations

This dissertation presents LAISYC, a modular location-aware architecture for intelligent real-time mobile applications that is fully-implementable by third party mobile app developers and supports high-precision and high-accuracy positioning systems such as GPS. LAISYC significantly improves device battery life, provides location data authenticity, ensures security of location data, and significantly reduces the amount of data transferred between the phone and server. The design, implementation, and evaluation of LAISYC using real mobile phones include the following modules: the GPS Auto-Sleep module saves battery energy when using GPS, maintaining acceptable movement tracking (approximately 89% accuracy) with an approximate average doubling of battery life ...
