Reverse engineering is the process of analyzing compiled software to reconstruct its source code or understand its structure and functionality. In the context of mobile applications:

It involves decompiling the APK (for Android) or IPA (for iOS) files.

Analysts can inspect the disassembled or decompiled code.

The goal is to uncover logic flaws, identify hardcoded secrets, debug issues, or assess security weaknesses.

According to CEH v13:

Reverse engineering is a common security assessment method to validate code quality and investigate vulnerabilities in mobile and binary applications.

Tools like JADX, Apktool, Hopper, and Ghidra are often used.

Incorrect Options:

B. App sandboxing restricts app access to system resources; it's a protection mechanism, not an analysis method.

C. Jailbreaking is the process of removing OS restrictions, not source code analysis.

D. Social engineering manipulates human behavior, unrelated to code or binary analysis.
