This means that even if you haven’t opened the multimedia message, the exploit can still infect your device. Once the exploit is successful, the attacker can gain complete control over your device, stealing sensitive information or even turning on your microphone and camera without your knowledge.

The Impact:

The StageFright exploit affects devices running Android versions 2.2 to 5.1.1, which accounts for a significant portion of the Android user base. The exploit’s impact was widespread, as it allowed attackers to target millions of Android devices with a single malicious MMS.

Protecting Yourself:

To protect yourself from StageFright exploits, it is crucial to keep your Android device updated with the latest security patches and software updates. Google has released security patches to address this vulnerability, and device manufacturers have also provided updates to fix the issue.
