Abstract：
Hundreds of millions of smartphone users are doing multitasking; however, the security implication of Android multitasking remains under-investigated. We find that Android multitasking is plagued by a serious security risk ?task hijacking. In this task, we answer 4 questions: Q1: How many types of task hijacking? Q2: How to craft the individual attacks? Q3: How to assess the vulnerability? Q4: How to defend task hijacking?During the evaluation, we analyzed 6.8 million apps from Google Play and other 12 popular third-party app markets.
