Abstract:
Smartphones become more and more popular. Android and iOS are two dominant mobile operating systems on the market. An interesting question is which one is more secure. We made a comparison by investigating applications that run on both Android and iOS and examining the difference in the usage of their security sensitive APIs (SS-APIs). We developed static analysis tools to perform massive static analysis for cross-platform applications on their SS-API usage. Our analysis showed that applications on iOS tend to use more SS-APIs compared to their counterparts on Android, and are more likely to access sensitive resources that may cause privacy breaches or security risks without being noticed.
We also proposed a generic attack vector that enables third-party applications to launch attacks on non-jailbroken iOS devices, and constructed multiple proof-of-concept attacks, such as cracking device PIN and taking snapshots without user's awareness. Our applications embedded with the attack codes passed Apple's vetting process and work as intended on non-jailbroken devices. Our proof-of-concept attacks have shown that Apple's vetting process and iOS sandbox have weaknesses which can be exploited by third-party applications. Our work helped Apple to fix the vulnerabilities in the latest release of iOS 7.
摘要:
智能手机越来越流行,几乎成为人们生活的必备设备,Android/iO是两种最主要的智能手机操作系统。一个有趣的问题是,哪一个更安全呢。我们通过观测Android/iOS应用程序及其使用安全API (SS-API)的差异来对比它们的安全性。我们开发了静态分析工具,通过它对SS-API跨平台应用程序进行了大规模的静态分析。分析结果表明,相对于Android,iOS应用程序更倾向于使用SS-API,并更有可能访问敏感资源,进而可能导致侵犯隐私或安全隐患而不被发现。
我们还提出了一个通用的攻击方法,通过它以第三方应用程序对非越狱的iOS设备进行登录攻击,并构建了多重概念验证攻击,如破解设PIN码、在用户未意识到的情况下进行拍摄快照。我们开发的嵌入攻击代码的应用程序通过了苹果的审核流程并可工作在非越狱的iOS设备上。多重概念验证攻击表明,苹果公司的审查程序和iOS沙盒测试存在弱点,并且可被第三方应用程序所利用。我们的工作将帮助苹果公司在最新版本iOS 7中修复此漏洞。
