About this app

Stagefright Detector App for Android Devices

Zimperium zLabs expert and VP of Platform Research and Exploitation, Joshua Drake (@jduck) discovered multiple critical vulnerabilities in Stagefright library and provided patches to Google to secure Android. We provided these patches to carriers and vendors through Zimperium Handset Alliance (ZHA). While the patches have been applied, it may be years until they reach all devices.

Zimperium zLabs created a Detector app to validate that you are running a version that is not vulnerable to the discovered Stagefright vulnerabilities. Some phone vendors have released partial patches to the vulnerabilities disclosed and this app can help you to understand if your device is vulnerable or not.

Stagefright is a critical Android vulnerability. It allows hackers to get 'media' or 'system' privileges on your device after processing an incoming MMS message, by surfing the web any one of the 11 potential attack vectors. In many cases, the attack do not require any end-user action. To make matters worse, the attacker can delete the MMS before you open it.

In order to test if your device is vulnerable, we built the ‘Stagefright Detector’ app.

This app will tell you three major things:
- whether your device is vulnerable
- which CVEs your device is vulnerable to
- whether you need to update your mobile operating system

Stay protected: ZIMPERIUM Mobile Threat Protection enterprise customers, vendors and carriers are protected from the Stagefright vulnerability without requiring any special update.

This application anonymously collect the results of the test and shares it with device vendors and carriers through ZHA. We do not collect any personal information.

useless. I can see the libstagefrights and they ain't the patch it's how my pos husband got into my cellphones all these years. I liberally had it fall to his autoscripts and get tagged by the errorprone [ OSS ] he installed. doesn't scan for real now only 1 sec. and then it claims I'm safe when I'm looking at the stagefright Infection myself.

Not vulnerable. I was Paranoid. I deleted them and wanted to make sure I was good to go and I am. If If not... you have to do is a factory reset. it's a pain but it would have to be done if I was vulnerable. Plain & simple.
