This is his only actual skill. He can talk his way out of or into things. That's it. It's why his credits as an "ebin l33t haxor" are all social engineering-related if it's not something a teammate did instead. All of his discussed tactics specifically target behaviors (blocking autowalk paths that bots use, using banwaves instead of individual bans to avoid revealing what outed them, convincing employees to give away confidential info, following them to where they're having lunch, lying about being part of DEFCON so he could get unique information other participants got, etc).
Because he's not really a hacker, he's just a scam artist which is a skill easily misinterpreted as hacking to the point of association. It's like a porch pirate telling you they're great at bank robberies. Sure, you can get an equivalent end result - stolen goods - but the scale, method, and means are all completely different and ultimately incongruous. You think if he could actually do half the shit the people he associates with do he'd be anti-piracy, pro-"as a service," and sucking corporate cock for fucking free? Hell no!
He knows it too, that's why he markets to kids who don't know it and just see all of the flashy techbro cargo cult shit like a stenography password or how his Flipper Zero is a totally lethal weapon. because if he looks like an ebin l33t haxxor to them, then he'll be seen as one by the greater community. You won't see him flex like that around people who actually give enough of a shit to call him out. Bet you he was real fucking demure in any team discussions at DEFCON.
