Ömer Göktaş, one of the top cybersecurity experts in the BugBounter Community shares a bug bounty tip you can all benefit from while testing mobile apps.

When conducting mobile app testing, after completing the final testing phase, it’s crucial to shift focus to scrutinizing the app’s native files for potential vulnerabilities. Begin by thoroughly analyzing all files, paying special attention to those related to user sessions.

For enhanced testing, consider utilizing the following steps:

Step 1: File Examination

Use a disassembler tool like apktool to dissect the APK file. Look for any sensitive information or configuration files.

Step 2: Email Manipulation

Within session-related files, identify email addresses and modify them. For instance, using Python:

Step 3: ADB Replacement

Before launching the app, overwrite the existing files with modified ones using ADB commands.

Step 4: User Impersonation

With luck, the app might load with a different user’s session, exposing potential authorization issues.
