koray105 on 2026-06-23 10:22: Nice little crackme. The validation logic was compact but fun: once the statically linked glibc rand/srand path was identified, the rest came down to faithfully reproducing the 32-bit state transitions and searching for a candidate that lands inside the accepted final range. Cute challenge, good lesson in not trusting libc PRNGs for key checks. :3
