We analyse how the app handles sensitive user data and workflow validation. This includes identifying where payment, approval or transaction steps can be bypassed, checking how client-side validation or insecure redirects can be manipulated and finding logic flaws that may lead to privilege escalation or unwanted data exposure. Our manual testing approach simulates real attacker behaviour to uncover vulnerabilities that automated tools often fail to detect.

We evaluate how the mobile app communicates with its backend. This includes checking for broken authentication, weak authorization, insecure data handling and issues like IDOR that could expose user information. We ensure data flow between the app and server is secure at every step.

Our review focuses on identifying weak coding practices, hardcoded secrets, insecure debug flags and configuration issues in CI/CD pipelines. We ensure the app follows secure development practices and that the build process does not introduce security risks.

We assess insecure storage, exported components, weak permissions, WebView risks and the ability to bypass root restrictions. This ensures the app is secure across different Android environments.

We analyse the strength of the app’s encryption, token handling and session management. This includes validating the cryptographic algorithms in use, checking the effectiveness of certificate pinning and other token protection mechanisms and testing for potential data leakage during both runtime and storage operations.

We simulate real-world tampering attempts to evaluate the app’s resilience against reverse engineering and runtime manipulation. This involves checking how the app responds to code injection and memory modification, assessing its binary integrity and evaluating its behaviour during dynamic testing to identify weaknesses that attackers could exploit.
