Title: The Evolution of Android Packing and Unpacking Techniques
Abstract: Nowadays, the Android packing techniques have be widely applied to preventing Apps from being repackaged or reverse-engineered. Meanwhile, the prevalent usage of packing techniques also improve the difficulties of Android malware detection because the malicious authors are also exploiting them to protect the malicious Apps from analysis. Although various unpacking solutions have been proposed to assist in the analysis of packed Apps, the packing techniques are evolving frequently, which require new unpacking solutions. The speaker will introduce the evolution of the common Android packing techniques as well as their characteristics. Also, in this talk, the existing popular unpacking techniques and their evolution process will be introduced.

Title: Facilitating the Removal of Kernel Vulnerability with Crash Triage
Abstract: Nowadays, kernel fuzzing projects like Syzkaller and Syzbot, have significantly expedited the discovery of vulnerabilities in the Linux kernel, finding more kernel vulnerabilities than those found in the past 20 years. However, state-of-art fuzzing projects suffer from several drawbacks. First, it generates a sheer volume of crash reports, many of which are "duplicated" reports caused by the same bug. While Syzbot uses a simple heuristic to deduplicate crash reports, we find that it is often inaccurate and cannot group many duplicate reports. Second, not all bugs need immediate patching, it usually depends on the severity of kernel vulnerabilities. Security Analysts usually use the manifested error behaviors to infer the exploitability of a vulnerability and prioritize the patching of the corresponding kernel vulnerability. However, only with the error behaviors in the reports, security researchers might underestimate the severity of one vulnerability. In this talk, I will introduce my recent research works on kernel crash triage to facilitate the removal of kernel vulnerabilities. More specifically, I leveraged empirical study and directed fuzzing to develop systems that automatically triage crash reports generated by kernel fuzzers.

- Dongliang Mu, Huazhong University of Science and Technology, China

Dongliang Mu is currently an associate professor in the School of Cyber Science and Engineering at Huazhong University of Science and Technology (HUST). He earned his Ph.D. in Computer Science from Nanjing University and fortunately was supervised by Bing Mao. During his Ph.D. career, he acted as a research assistant of Professor Xinyu Xing at Pennsylvania State University. His research focuses on Software and System Security. More specifically, his research interests span the areas of Vulnerability Fuzzing, Vulnerability Analysis (including Crash Deduplication, Crash Diagnosis, Vulnerability Reproduction), and Vulnerability Assessment. His recent projects focus on Linux Kernel Security, including crash deduplication, severity assessment, and patch quality assurance. His research work is recognized for its highly practical impacts. His works have been published at top-tier conferences, including IEEE S&P, Usenix Security, CCS, NDSS, ASE, and TSE. In 2018, he is a recipient of ACM CCS Outstanding Paper Award (2018). His past research has been covered by many medium, such as ChinaDaily, Tencent, Sohu, and CSDN. He was also the organizer of NSA memory corruption forensics competition.
