The files in this CTF may not execute in automated sandboxes and for most of them dynamic reversing might not work. For some samples though, changing the code and dynamically reversing it could speed up the capture process! The idea is to use your skills and reverse engineer in order to capture the flags. However, there are no limits — use your imagination, any hack that works is good!
