Code Obfuscation and Reverse Engineering Questions

Techniques, trade offs, and platform specific practices for protecting mobile application logic and binaries from reverse engineering and tampering. Candidates should understand code obfuscation approaches such as symbol stripping, control flow obfuscation, string and resource encryption, native library protection and binary packing, as well as runtime anti tampering and anti debugging measures. Coverage includes platform release practices such as Android release tooling and application signing, ProGuard and R8 style shrinkers, iOS code signing and hardened runtime configuration, secure key handling for client secrets, and approaches for protecting embedded native code. Evaluate how protections affect crash reporting and diagnostics, testing strategies to validate protections, and the balance between protection, performance overhead, maintainability, and recoverability during incidents.
