DEF CON 33

Lockheed Martin CTF Challenge

Lockheed Martin's capture-the-flag challenge presented a pixel map of colored cubes. The solve: identify the correct reading order (left to right, top to bottom), map each cube to its hex color code, then decode the hex byte-by-byte as ASCII (each color is 3 bytes, each byte one character) to reveal the flag.
