The challenge I am presenting to you was part of the CyberSci Regionals 2024 edition and was the first in the Reverse Engineering track. Being an avid reverse engineering enthusiast myself, I didn't even look at the other challenges and immediately started with the one called "Vector Veil", unaware that I was embarking on a journey that would take up all the time I had at the competition...

NorthSec is a significant cybersecurity event in Canada that occurs annually in Montreal. One of its highlights is an exceptional 48-hour CTF competition that captures the interest of many. This year, 30 students from PolyCyber's CTF Team had the opportunity to participate and learn new skills.
Two members of our CTF competition team wrote write-ups for tasks from the RITSEC CTF.
Our team, PolyCyber, is planning to host its own CTF competition a few months from now, so we were eager to see what other student clubs were doing across the country. Hence, we registered for MapleCTF, organized by The Maple Bacon CTF team of the University of British Columbia. This is what led us (Ch0ufleur and Erreur-404) to try and tackle Maplewave-0, a “reverse engineering” and “audio” tagged challenge made by xal#3845.
