Unless his attitude and stance changes, there’s not a single red team that I could see taking him. You can’t just throw someone who wants to be a criminal into pentesting and think it’ll go well
He’s talented, but the problem is jobs like pen testing require a LOT of trust to work in. So far this guy has said and shown that he intents on staying in cybercrime rather than doing legitimate work.
As it stands, given how he’s acted, I can’t see a single company that would let him pen test their systems or a red team that would take that risk to their reputation.
