Welcome to the 2nd Panda Challenge. As promised, this will be harder. In the previous one we had more than 1 thousand downloads and just 44 right answers, let's see how this goes. Joxean has been the creator of this challenge. This are the "instructions" that Joxean wants you to know before starting:

"To create a program which automatically solves the problem posed by the program by communicating with it using the protocol this program understands."

The file can be downloaded here. Enjoy yourselves and don’t forget to send the challenge solution (the created program) to pandachallenge at pandasecurity dot com

I will be publishing updates on Twitter, and next Monday I'll let you know the final results.

The terms and conditions of the competition can be downloaded from here.
