Good challenge. For beginners: Whenever you are given executable, you must take a close look at it with proper tools...

There is another tool mentioned below, also you should definitely have IDA in your toolkit.

Would be very interesting to look for this in real apps in the future.

Try to find vulnerability in that app

Oh boy, I solved the challenge now. I saw the vulnerability from the start, but didn't know that syntax existed. Honestly, ChatGPT helped a lot. It gave an example of the attack, and that's exactly it.

Use a decompiler like Ghidra to just see the source code.
