EC-Council Certified Ethical Hacker (CEH) v12Mobile Platform, IoT, and OT HackingEasy
A mobile application developer is concerned about the security of their Android application. They want to prevent attackers from analyzing the application's source code, debugging it, or modifying its behavior at runtime. Which technique is primarily used to obscure the logic and make reverse engineering more difficult for Android applications?
- ACode Signing
- BObfuscation
- CData Encryption
- DNetwork Segmentation
Show answer & explanationAnswer & explanation
Correct answer: B. Obfuscation
Obfuscation transforms code to make it difficult to understand and reverse engineer without altering its functionality. This technique is commonly used in mobile application development to protect intellectual property and prevent tampering.
Why the other options are wrong
- A. Code Signing verifies the integrity and origin of an application but does not prevent reverse engineering.
- C. Data Encryption protects data at rest or in transit but does not obscure the application's executable code.
- D. Network Segmentation isolates network segments and is irrelevant to protecting an application's source code from reverse engineering.
Mobile App Code Obfuscation
The process of intentionally creating code that is difficult for humans to understand and reverse engineer, while still maintaining its original functionality.
- Protects intellectual property from competitors.
- Makes it harder for attackers to find vulnerabilities.
- Commonly involves renaming variables, classes, and methods, and adding junk code.
Memory trick: To hide mobile app secrets, obfuscation makes the code a puzzle.
