Secure Programming and Code Hardening Techniques
a) Opaque Loops
Theoretical Explanation: Opaque loops are loops that, when viewed externally, have no clear purpose. These loops make code analysis more difficult. Attackers struggle to understand the function of the loop, making the code harder to reverse-engineer.
Example Applications:
- Adding loops created with random conditions to complicate code analysis.
- Introducing loops that do not affect program functionality but confuse the analysis.
- Using opaque loops to increase program runtime, misleading attackers.
