How I hacked a hardware crypto wallet and recovered $2 million

I was contacted to hack a Trezor One hardware wallet and recover $2 million worth of cryptocurrency (in the form of THETA). Knowing that existing research was already out there for this device, it seemed like it would be a slam dunk. Little did I realize the project would turn into a roller coaster ride with over three months of experimentation, failures, successes, and heart-stopping moments. It reminded me that hacking is always unpredictable, exciting, and educational, no matter how long you've been doing it. In this case, the stakes were higher than normal: I only had one chance to get it right.
