Challenge 2

On the second installment of this reverse engineering series I present you with a new challenge. This time you are a secret agent, and you are on a very important mission. Some documents are stored on a locked safe that you have to open. There are some weird symbols and some green bars that oscillate up and down. Your intuition tells you that the safe will open when the three bars are full!

Now you start to think… this is the way, but how I am gonna make it happen?

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!

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.
