Stagefright is believed to be the worst Android vulnerability yet discovered. All devices running Android versions Froyo 2.2 to Lollipop 5.1.1 are affected, which are used by approximately 95% of all Android devices, by nearly 1 billion people. Hackers only need to know your phone number to infect your device.
The malware is delivered via a multimedia message (MMS) sent to any messenger app that can process a specific video format - like an Android device’s native messaging app, Google Hangouts and WhatsApp.

The most common Android messaging apps load videos automatically. You can protect yourself by disabling the Auto retrieve feature in your default messaging app, so that videos cannot be loaded in the background and infect your device.
