Das Premium-CTF mit Fahren an der Freude!
Difficulty estimate: - hard
Points: round(1000 · min(1, 10 / (9 + [3 solves]))) = 833 points
I’ve been waiting anxiously for a package… Do you know what I bought?
Note: If the binary segfaults, try using a newer kernel (we verified that it works on Linux 5.0 and later). Sorry about that!
Note 2: Please download the challenge again (or change the byte at file offset
0x0f), we fixed an alignment issue on some versions of Ubuntu (thank you to Redford for reporting that one)!
