What is Stagefright?
- A vulnerability has been identified in some Android phones worldwide that can potentially allow access to multimedia files, or potentially for a phone to be taken over by receiving a malicious MMS message.
- The vulnerability may be contained in the “Stagefright” media playback engine.
- The user does not need to open an attachment or download a corrupt file. The malicious code would take over instantly, the moment a malicious text message is received
What Can I Do?
- You can disable the auto-playing feature for MMS messages on your device for your Text Messaging Apps (includes built in text messaging app that came with the device, Google Hangouts or any 3rd party messaging app that you may use to read your MMS messages). To do this:
- Go to App Settings
- Disable ‘Auto-retrieve’ for MMS messages in the Messaging app's settings.
