Download the sample and open it in a Hex Editor, there you can see the Topaz or Mobi at the top right. You can also look at the file, size. If the sample has several 100 kb then it is most likely Topaz, Mobi files are much smaller. I don't think Topaz will be broken, because none of our favorite hackers seems to be interested in doing it.
