Challenge 1

This is the first of a series of reverse engineering challenges that I am going to craft for this blog. This one should be easy, with a little bit of patience I am pretty sure that you can get the flag stored inside the file.

If you decide to go and solve this challenge, please, tell me how you did it on an email (david@studiosi.es) and I will collect the solutions on a future post. Even better, do a write up, post it somewhere online and I will link to it here!
