Android Application Security
This is a write-up of Android Application Security resources and tools which helps in Android Application pentesting and security research. This write up is a step to provide good quality content on different topics in Android Application Security. Content will be updated from time to time to make sure the quality of resources and latest updates related to Android Application Security.
Note : This is a compiled write up of Android Application Security resources. We are not promoting these resources in anyway and it is also possible that there would be many more great resources on Android Application Security which we might miss to add to this write up. If you know any good resources let us know by commenting below and we will add it to the write up/List.
Pentesting Environment
Host device
A Windows/Linux/Mac OS device will work absolutely fine to do all the task for Android Pentesting.
Basics setup must Include :
- Any one (Windows/Linux/Mac) OS machine.
- Wifi-Network
- One rooted device or any Android Emulator (like Genymotion and similar )
- One Interception Proxy traffic (Like Burp Suite /ZAP etc )
Test Device
If you are testing on a real android physical device. It should be root to have the root privilege to access all the system files and also to install all the required tool on the device for security testing.
If you don’t have an Android rooted phone, you can use Android emulator/virtual device for testing.
Root Access :
For easier pentesting of Android application, having a root privilege on device/emulator is recommended and allows to perform many tasks. The Benefits of rooting your device for pentesting are:
- Root access to file system
- Allow to install all the security tools
- Debugging and analysis capabilities
- Access to application runtime
Below mentioned resources can be used to get a full rooted Android device.
Rooting android devices :
Android is built on linux kernel and super user in linux is known as root. Root user can perform any operation on android device and the process of getting super user is called rooting. Rooting an Android device requires
- Unlocking the boot loader
- Install recovery tool like TWRP and similar tool
Note : Depending on your device configurations you can select the tool with appropriate version.
