Caterpie

Prerequisites & Requirements

• Basic knowledge of Python : Understanding of fundamental Python syntax, functions, and control structures
• Familiarity with random number generation : Knowledge of how pseudo-random number generators (PRNGs) work
• Understanding of seeding concepts : How seeds initialize PRNGs and produce deterministic sequences

What will you learn?

• Reversing random integer generation : Understanding how to predict or recover "random" values when the seed is known or can be determined
• Seed recovery techniques : Learning how to brute-force or reverse-engineer PRNG seeds from observable outputs
• Time-based seed exploitation : Recognizing vulnerabilities when timestamps are used as seeds
• Sequential PRNG behavior : Understanding that consecutive calls to a seeded PRNG produce a predictable sequence of values

Tools

• Python
