Ledger Hardware Wallet Security Crisis: Implants Found, Resellers Cut Ties

What we know

An account on X warned users to move crypto off Ledger devices, citing another account on X's breaking report that MediaMarkt — Europe's largest electronics retailer — stopped all Ledger hardware wallet sales following a tamper implant found in one German customer's device, with possibly 11 countries affected. Meanwhile, @TheBlockCo reported that OneKey has cut ties with reseller CryptoBilis, frozen new reseller approvals, and is offering free replacements to eligible buyers; OneKey says it has received no reports of losses from its own customers. This coincides with discussion of a UK-based crypto holder being robbed at knifepoint for $800k, cited by multiple accounts as a reminder of the physical security risks of public crypto holdings. Alistair Milne also highlighted France's new mandatory declaration policy for €100k+ self-custody BTC holders as creating similar physical security risks.
