We have prepared a very warm welcome for you!
File: warmwelcome
Solution
Challenge file is a binary, which executed is presenting some ascii art fireworks.
I had to use Ghidra
to realize, that I need to hit q
(line 57) to end the fireworks and start the challenge.
./warmwelcome
Hope you enjoy the firework we prepared for you! Now give me a flag :))
