The Synacktiv summer challenge is back!
Edit: we had an issue with the binary prior to 2019-06-19 09:15, please download it again.
Dana has just finished a nice brain teaser for his friend Alonzo.
It is a Linux executable that accepts a single argument, and displays a string.
Can you craft an input that makes the program print
Once you have found a valid input, validate the challenge by sending your solution to firstname.lastname@example.org.

P.S.: Of course, it might be possible to exploit a bug in the validation logic and take a shortcut here. Even though they will not qualify for a prize, do not hesitate sending us these solutions!
