How i can protect my android from Master Key Vulneralability?

Question

When i install apps ,that i take from my friends , it seems quite fishy , so how to check that the apps are trusted or not.

Answer 1

You can check whether your device is affected using e.g. Bluebox Security Scanner.

To close the vulnerability, your device needs root access. If that pre-condition is given, there are different fixes available, e.g.

• Master Key dual fix (a module for the xposed-framework)
• Master-Key Security Patch (again a module for Xposed)
• ReKey (a stand-alone app)
