In late July of 2015, a number of vulnerabilities were found on Android's libStageFright multimedia component. Called Stagefright, the vulnerability put millions of Android devices at risk, allowing remote code execution after receiving an MMS message, downloading a video file, or opening a page embedded with multimedia content. Trend Micro discovered one such vulnerability within the Stagefright library during that time that could virtually "kill" an Android device when exploited.
