Nostr and Bitcoin and hardware tinkerer. It’s all coming together eventually, somehow, soon!
#SovEng SEC-08
Reverse-engineering Ledger hardware implant. Using more old-school hardware pro methods, ie the playbook as of ~year or so back. Btw, this is 3 months old, so it’s not like the implants just arrived on the scene
You move air, you move dust. And you move a lot of air


Physically larger hardware wallets also means more room for implant circuitry and a larger antenna. In this particular case, the attackers also gained more internal volume to work with by replacing the original battery with a smaller one
That’s a lot of Ledgers getting cracked open right now, physically, by concerned owners. In retrospect, given the threat model, a clear or matte casing that makes visual inspection possible should be the norm / best practice
Missing @ODELL and @CITADEL DISPATCH. In the meantime, grateful for the deep back catalog of conversations with amazing builders
GM. Keep going

Much Nostr flex incoming - thanks to relays being the major pillar in the overall design 💪
