5 - TUX-BOMB!
Yeah! We control a zombie server which is connected to a TUX-Bomb. These
servers are located in the head of the organization. This bomb can destroy a
lot of their servers and employees. But we have no access since we are not in
possession of a valid user name and activation key. So here's your job: Find a
way to detonate the TUX-BOMB!

Hint: There is a small

typo on your way to the flag - don't get confused about it. Just use your
intuition and everything should work fine!
