SMU researchers boost security of Google’s Android mobile systems


Singapore (Singapore). – “Ms Su Mon Kywe, a PhD candidate, and Associate Professor Li Yingjiu from SMU’s School of Information Systems have discovered several security weaknesses in Google’s Android 4.4 and Android 5.1 systems when performing vulnerability analysis on the Android framework as one of their security research projects with Huawei. The weaknesses were reported to Google which has subsequently fixed the vulnerabilities in the newer versions of their Android systems.
The SMU team’s purpose of conducting the vulnerability analysis was to discover security loopholes in the Android systems and report them in a timely manner, so that platform providers such as Google and Huawei can fix the vulnerabilities before they are exploited by real hackers.
The team’s research involved several static source-code analysis, such as building call-graphs and analysing data-flow, on Android Open Source Project (AOSP) published by Google. The source code of AOSP is also used by other platform vendors, such as Samsung and Huawei, with their own customisations. The result of SMU researchers’ analysis revealed that several types of attacks can be launched on mobile users using AOSP versions 4.4 and 5.1.”
