Lonely Island was one of the tasks on FAUST CTF 2021.
This task was a multiplayer FPS game based on Godot engine. This is something you don’t see on CTFs often, let alone on attack-defense ones. One notable example I can think of is Pwn Adventure on Ghost in the Shellcode CTF many years ago. Although Pwn Adventure was considerably more complex, it was a jeopardy competition, and yet Lonely Island appeared on an attack-defense CTF.
Caidanti was a reverse/pwn task with two flags.
The task had two binaries -
caidanti-storage-service, running on Google’s Fuchsia operating system, which is currently under active development.
printf was a pretty typical pwn task: you get binary, libc, network address, and you have to gain an RCE. The vulnerability is an unsafe
allocawhich allows one to cross the gap between stack and libraries.
Unknocking was a networking task on CyBRICS CTF 2019 quals.
DevMaster 8000 and DevMaster 8001 were sandbox challenges on Google CTF 2019 quals.
“If on a winters night a traveler” was a pwn task on 0CTF/TCTF Quals 2019. You have to pwn a custom buggy encryption algorithm for Vim.
refrain was a misc task at 0CTF/TCTF Quals 2019 where you had to reconstruct input data from a program trace.
Elastic cloud compute (memory) corruption (or EC3 for short) was a binary pwn task on recent DEF CON CTF 2018 Quals.
“slot machine” was a hardware task in the reverse-engineering category on Google CTF Finals 2017, which took place in Zurich back in October 2017.
