Brochacho left behind a single image before disappearing after finals.
According to his friends, he spent the last few days insisting that "everything was in the image" before refusing to elaborate further.
Naturally, nobody took him seriously.
The only artifact recovered from his machine is attached below. Whether it contains anything useful, a cry for help, or the consequences of severe sleep deprivation remains unknown.
Your task is simple:
Find the flag.
#Notes
Note
- Everything you need is already here.
- Sometimes files tell different stories depending on how you choose to read them.
- The difference between what is shown and what is stored can be surprisingly important.
- Brochacho was known for making things unnecessarily complicated.

The challenge page is not the artifact. Brochacho had a habit of leaving important files in places that matched the week he was working on. Start by exploring the week itself/
Hint 2view
You found the key. The next question is whether you've found something that needs one.
Hint 3view
The image has already rewarded you once for looking a little deeper. It may be worth asking whether you've finished exploring it.
The key is useful. The question is: useful for what?
A very simple bitwise operation stands between you and the flag.
