Talk Title: A Semantics-Centric Approach to Fight Android Malware
Series: CS Colloquium
Abstract: This lecture satisfies requirements for CSCI 591: Computer Science Research Colloquium
The number of new Android malware instances has grown exponentially in recent years. McAfee reports that 2.47 million new mobile malware samples were collected in 2013, which represents a 197% increase over 2012. Greater and greater amounts of manual effort are required to analyze the increasing number of new malware instances. This has led to a strong interest in developing methods to automate the malware analysis process. In this talk, I will present a series of semantics-centric techniques to fight Android malware. First of all, we need a powerful analysis framework to quickly understand the inner-working of a given malware sample. To this end, we developed a virtualization-based analysis framework called DroidScope, which can seamlessly reconstruct both OS and Java level semantic views to provide a holistic view of a malware attack. Moreover, we need to automatically classify malware samples by their functionalities and behaviors and discover zero-day malware. We proposed a new semantics-based technique for malware classification, by capturing the semantics-level behavior of an app in form of ``Weighted Contextual API Dependency Graphs". Then by computing the similarity between these graphs, we can accurately and reliably detect malware variants and zero-day malware. Furthermore, we believe that malware detection can be more effective by getting end users into the loop. In particular, we developed a new technique that can automatically generate human-readable descriptions of a given app, such that any unexpected descriptions will cause suspicions and flagged by end users. To encourage wide adoption and follow-up research, these research products are available in form of source code release and/or web services.
Biography: Heng Yin is an Associate Professor in the department of Electrical Engineering and Computer Science at Syracuse University. His research interests mainly lie in computer security. In particular, he is interested in applying program analysis techniques and virtualization techniques to improve software and system security and defeat malware attacks. He earned his PhD degree in Computer Science from the College of William and Mary in July 2009. He was a main contributor in BitBlaze team at UC Berkeley before joining Syracuse University. In 2011, he received NSF Career award.

Talk Title: Ultrafast and Nanoscale Interfacial Charge Transport and It's Interaction with Electomagnetic Waves
Abstract: Interfacial charge and energy transport is of fundamental importance to nanoscience and devices. It is critical to the development of quantum plasmonic junctions, ultrafast photoelectron sources, and compact electromagnetic radiation sources (millimeter wave to THz to x-ray), which have applications in imaging, communication, energy, and security. The rapid development in nanotechnology and ultrafast laser optics has opened up great opportunities to control interfacial transport at ultrashort spatiotemporal scales and offers unprecedented scientific advances. However, the understanding of the underlying physics is limited and scaling laws are largely unexplored.
In this talk, I will present recent advances on the modeling of electron transport at contact interfaces and ultrafast electron emission from metal surfaces. Scaling laws for electrical contact resistance between dissimilar materials are constructed for a large range of material properties and geometrical aspect ratios. Spreading resistance and current crowding effects are quantified from the exact solutions constructed. Validated against numerical codes, they are recently applied to electrically pumped nanolasers. A general theory is developed for the quantum tunneling current in a nanoscale metal-insulator-metal junction, covering the direct tunneling, field emission, and space-charge-limited regimes. I will also show our recent theory for laser-induced electron emission, by solving the time-dependent Schrödinger equation exactly, for arbitrary combination of dc bias and laser intensity. Other modeling efforts on geometric diodes, electromagnetic power absorption, and THz Smith-Purcell radiation will be highlighted. Future research prospects on these topics will be discussed.
Biography: Peng Zhang is an Assistant Research Scientist in the Department of Nuclear Engineering and Radiological Sciences at the University of Michigan (UM) at Ann Arbor, where he received his Ph.D. degree in 2012. He was a recipient of the UM Richard and Eleanor Towner Prize for Outstanding Ph.D. Research, the UM Rackham Presidential Fellowship Award, and the IEEE Nuclear and Plasma Sciences Graduate Scholarship Award. He has authored journal publications on electrical contacts, classical, ballistic, and quantum diodes, electron emission, electromagnetic heating phenomenology on rough surfaces, surface flashover and discharge, high power microwave sources, pulsed power systems, z-pinches, quantum electrodynamic laser-plasma interaction, and Smith-Purcell radiation. His current research interests mainly focus on theoretical and computational nanoscience and devices, including quantum plasmonic junctions, ultrafast photoemission, and novel compact electromagnetic radiation sources.
