He's a guy who has anomalous hacking abilities. That's pretty much exactly what I would have expected, without a single twist or anything that really caught my attention. There's nothing that's presented here that couldn't be done just as well with SCP documentation, which then begs the question "why bother with the UIU?" The idea of GoI formatting is to present some new perspective on something; if you gave some new information about Mr. Hax that only the FBI would process, "guy who hacks" might actually be a bit compelling. As it is, though, there's not much there there.
