Introduction
Challenge: file-run-2
Category: Reverse Engineering
Description:
A program has been provided to you, what happens if you try to run it on the command line? Download the program here.
Solution
We have been provided with a file called run. If you try to run the file like this:
./run
It won't work as expected. You should first give yourself permission to execute this file.
chmod +x ./run
Now if you try to run this, it will ask you for an argument. So let's pass the given argument, "Hello!"
./run Hello!

Conclusion
This one is what I think is one of the easiest challenges after file-run-1 ever on the picoCTF 2022.
