Hey you,
Do you want to dive into the world of forensics? Easy-hide challenge from Unbreakable 2024 is a good way to start. ๐ซถ
The contest is over at this moment and the flag cannot be submitted. However, learning does not depend on the flag submission.๐
Given that the task is telling us that there is something hidden inside, my first thought was to ease my research using Aperi'solve.
I downloaded the file and uploaded in the mentioned resource.
I downloaded the files and discovered a new image. Do you think that the flag is visible? Well, not yet. The image is broken. I edited the signature using HexEdit. It was easy to find the magic bytes, since the extension (.jpg) is a great tip. ๐ค A list of file signatures can be found here.
After the edit, I saved the file and What a beautiful day, indeed!๐น
