Challenges

Description:

A CUDA path tracer that renders a scene from test.obj into render.ppm... except the author "accidentally shreddered all the pixels." Whoops. Guess you'll have to figure out.

Description:

Baby's first CUDA reversing. Reverse embryoturing to recover the flag

Once you have it, run /challenge/flagcheck with it to get your real, submittable flag:

./flagcheck 'ctf{...}'

Description:

Yet another min3craft challenge. The flag is hidden in a Minecraft world.

Download Le Epic Challenge.zip, drop it into your saves, load the datapack and play it, or just reverse the datapack functions offline.

Recover the flag from the world and run /challenge/flagcheck with it to get your real, submittable flag:

./flagcheck 'ctf{...}'

DECLASSIFICATION ARCHIVE // CASE FILE: ██████-███

WARNING: DATA SUBJECT TO THE STATE SECRETS ACT OF ████


DECLASSIFIED ASSET: PAWTOMATON

The document below was intercepted during a deep-sea data-cable tap on the ██████████ underwater processing array. This transcript details the automated logic engine powering their perimeter defense grid before the network was severed.


CLASSIFICATION: SECRET // NOFORN

DECLASSIFIED OPERATIONAL INTEL

We intercepted the core firmware binary for a standalone defense asset. The primary target is a ██████████ ████████ required to extract the ██████, remains locked down by an ██████████ ████████ ███████████████ ████.

To protect its state transitions from analysis, the architect built a completely unreadable control flow directly into the assembly. The program utilizes zero ███████████ ████████, executing entirely through a single data-transfer instruction matrix. ████████ ███████████ will simply hang.

Your primary objective is to parse this uniform instruction stream, unmask the hidden cellular automata state processing, and reverse-engineer the intensive █████████████ ███████████ designed to obscure the █████ validation. You must recover the correct ██████ ███ to satisfy the automaton matrix, which will force the binary to yield the ██████.
