The bigger guy of the two (the one doing all of the talking) looked like he could hardly contain himself. At times it looked almost as if he was smiling, as if he was thinking "I cannot believe we are getting away with this, we are going to be so f**king rich".
The smaller dude looked just as guilty, they probably think they are being clever with all these updates and videos to throw everyone off. If they did get in touch with law enforcement the first ones they should be looking into is those two clowns.
The "smaller dude" as you put it, has already served time for hacking/malware. I have no judgement whether he was a part of this or not, although I would assume he is a decent coder ( hey, at least his father hires good developers!). I know if I were to try and use someones login credentials to pull this off, I would have certainly tried for his, at the very least for the comedy factor.
