It’s worthless to create a highly secure app if the servers that store and process customer data have security flaws; on the other hand, even if your servers are totally safe, an insecure app could allow consumer data to be retrieved or diverted to a remote attacker.
As a result, client-side operations in mobile application penetration testing include:
The installed app’s decompilation
Searching for sensitive data that has been hard-coded into the app
Verifying the security of credentials stored locally
Checking to see if SSL certificates and signatures are genuine
Detecting unsafe cryptographic usage for data transmission or local storage
Analyze the source code (if appropriate)
Ensure that automatic updates do not serve as a conduit for attackers to insert malicious code.
After deleting the programme, double-check that any sensitive data has been erased.
Searching for unintentional data transmissions, such as the user’s phonebook when it isn’t needed
The app security testing service also includes the testing of the app’s online services.
To make sure that the backend servers do not leak consumer data to third parties, the following areas are thoroughly examined:
- Errors with server configuration
- Server code or scripts with flaws
- Advice on data that may have been exposed as a result of previous failures
- Checking for known security flaws
- Advice on repairs and future security strategies to reduce the risk and inducement to attack
Typical flaws uncovered during a security audit of a mobile app
Man-in-the-middle (MITM) attack vulnerability
On mobile devices, important data is stored insecurely.
Cryptography is being used in an insecure manner.
Session management issues
Unauthorized access to the accounts of other users
Injection of SQL
Injection of commands
Vulnerabilities in well-known platforms
Back doors and debugging possibilities
Errors that cause sensitive data to leak
ACLs that aren’t working/passwords that aren’t strong
Best tools for Mobile App Penetration Testing
QARK is a word that comes to mind when (Quick Android Review Kit) QARK is one of the mobile app security testing tools meant to analyse source code and identify potential security flaws in Android apps. It is community-based, open to the public, and free to use. It also tries to give dynamically produced Android Debug Bridge (ADB) commands to help validate suspected vulnerabilities.
Drozer is an Android security and attack framework with a lot of features. Through Android’s Inter-Process Communication (IPC) protocol and the underlying operating system, mobile app penetration testing kit allows you to play perform the role of an Android app and interact with other apps. The fact that it is interactive distinguishes it from other automated scanners.
MobSF is an acronym that stands for “Mob (Mobile Security Framework) Mobile Security Framework is an Android and iOS app security testing tool that can perform static, dynamic, and web API testing. MobSF can be used to quickly assess the security of Android and iOS apps. Binaries (APK & IPA) as well as zipped source code are supported.
Top cyber security companies use custom script and custom tools apart from above mentioned tools to achieve the best results and identify security vulnerabilities in mobile apps.
