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

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
