RED micro-site now out!

Need confirmation.

Is it enough if I just tell you that they're not the ones from the CS cubes?

If not, there's this from my thread:

큐브의 파편 (Cube Fragment) (75%) x1 or 큐브의 파편 (Cube Fragment) (25%) x5 (No Recipe Needed)
Req. Profession Level: 11 | Fatigue Cost: 0
Ingredients:
- Occult Cube x-1
- Occult Cube x-1
- 수상한 큐브 (Occult Cube) x-1

It's the "recipe" for extracting Occult Cubes as an alchemist, and presumably the cube extractor would work the same way.
