Hacking Android

By: Srinivasa Rao Kotipalli

Overview of this book

With the mass explosion of Android mobile phones in the world, mobile devices have become an integral part of our everyday lives. Security of Android devices is a broad subject that should be part of our everyday lives to defend against ever-growing smartphone attacks. Everyone, starting with end users all the way up to developers and security professionals should care about android security. Hacking Android is a step-by-step guide that will get you started with Android security. You’ll begin your journey at the absolute basics, and then will slowly gear up to the concepts of Android rooting, application security assessments, malware, infecting APK files, and fuzzing. On this journey you’ll get to grips with various tools and techniques that can be used in your everyday pentests.

External storage

Another important storage mechanism in android is SDCARD or external storage where apps can store data. Some of the well-known applications store their data in the external storage. Care should be taken while storing data on SDCARD as it's world writable and readable or better yet simply remove the SDCARD from the device. We can then mount it to another device, for us to access and read the data.

Let's use the earlier example and instead of storing it in the internal storage, the application now stores it on the external storage, that is, the SDCARD:

            String publicKeyFilename = public.key;
            String privateKeyFilename = private.key;

            GenerateRSAKeys generateRSAKeys = new GenerateRSAKeys();
            Security.addProvider(new org.bouncycastle.jce.provider.BouncyCastleProvider());

            // Generate public & private keys
            KeyPairGenerator generator = KeyPairGenerator.getInstance("RSA", "BC");
