My thinking is that it's for Hunt The Truth. The latest episode referenced someone going by the name of 'Pharaoh.' It is revealed this person is female. At the end of the episode, there's a weird noise, similar to morse code. Putting it through certain programs reveals the words stolengauntlet.com. This takes you to an altered Ford commercial for the ARG. But the interesting thing isn't the commercial, but the youtube channel connected to it. Shar Eldy. This is an anagram for Dr. Halsey. It may be that 'Pharaoh' is in fact Dr. Halsey. If this is the case, then Ben's whole investigation is about to be blown right open. Halsey knows everything there is to know about the Spartan-II Program. With her out of UNSC custody, she can do some major damage with that knowledge. I've only now realized why Palmer is so obsessed with eliminating Halsey. While Palmer likely doesn't know the full story, she probably knows enough to understand just how big of a threat Halsey is.
