I watched part of it and most things might of learned from YouTube. Nothing very advanced in what he was showing. Most things get from Hak5, so we know he overpaid too.

It seems... But I also made search on his past, examined his 'Twitter & GitHub' account. And so far, I find that you can become better by doing a big job on yourself.
I just posted the interview made by ‘Shawn Ryan Show’, which was interesting as a ‘hacker’s menu’.. (customized Flipper-Zero, Chameleon Ultra Radio, etc..).
I won’t advocate an 'ex-drug addict', on the other hand I’ll go straight to his new life & his way of wanting to change the world.. Period! I don’t advertise on him!
