  The challenge in question is just a jpg of the logo of ruxcon 2004. The password for the next level is presumably steganographically encoded in it. The challenge is much easier (and perhaps only possible) given the original image, but the logo is no longer on the internet. After scouring web archive and using all Google fu at my command I found some instances of the image but all in different sizes/dimensions. The name of the level is "the properties of a mirror" which hints that you need to find a mirror of the original site in order to solve the level, and I think that the mirrors are no longer online. Note for anyone unfamiliar that this level is not at all representative of vortex - all the other levels are all hard core exploit implementation and not stego challenges. In general I don't like stego because I feel that it is more of "try to guess what I'm thinking" than solving interesting challenges.

I would assume that if this were the case someone who has already completed that level could check if where they found it was still up? Perhaps this is not the interpretation of the level name that the writers had in mind?

      The challenges are years old and not actively maintained. Until this thread I haven't seen any people who passed level 12 or so
