According to the research that I also posted, that image is simply the fake profile picture of the elite hacker. When he posted that, people used tineye.com to see if that profile picture existed anywhere else on the internet, it did not.

So what makes this so wow... is that Flynn, called out this guy, on an anonymous message board with his own avatar to tell him, "We know who you are".

My research was sent to him before it was released publicly, so before the target was alerted that we were on to him, Flynn and team were able to get to work.
