Reverse engineering is the process of analysing a system or software to understand its components, functionality, and architecture. In the context of mobile apps, reverse engineering typically involves deconstructing an app’s compiled code to reveal its source code, data structures, and logic. The goal may be to identify vulnerabilities, extract sensitive data, or alter the app’s behaviour for malicious purposes.
Code tampering occurs when an attacker manipulates or alters the source code, binaries, or execution flow of a mobile application. This tampering can take various forms, including modifying the code to bypass security checks, reverse engineering to steal intellectual property, or injecting malicious code to steal sensitive data. Mobile apps, which often handle sensitive information like personal data, payment details, and corporate data, are prime targets for these attacks.
Improper platform usage refers to the failure to properly use security features provided by mobile platforms, such as Android and iOS. Both operating systems offer robust security mechanisms that, when properly utilised, help safeguard mobile apps from common attack vectors. However, improper configuration or ignoring these features can lead to critical vulnerabilities, which can be easily exploited by attackers.
When testing mobile apps, penetration testers must focus on how these platform-specific features are being leveraged. Whether it’s improper handling of APIs, weak authentication methods, or ineffective data storage solutions, improper platform usage can leave significant security gaps in an otherwise well-constructed app.
