Problem-Solving Workflow

1. Start with strings extraction - many easy challenges have plaintext flags
2. Try ltrace/strace - dynamic analysis often reveals flags without reversing
3. Map control flow before modifying execution
4. Automate manual processes via scripting (r2pipe, Python)
5. Validate assumptions by comparing decompiler outputs
