According to a MediaMarktSaturn spokesperson, the retailer removed all Ledger products from its stores and online platforms on Tuesday following reports of hardware wallet tampering. An X user claimed Monday that two Ledger wallets purchased from separate MediaMarkt locations contained unauthorized cables and cellular modules.
Ledger is investigating reports that implants in some devices transmitted users' recovery phrases over cellular networks. Former Mt. Gox CEO Mark Karpelès also reported Tuesday that a Ledger Flex purchased at Singapore's airport contained a spy implant. Ledger has not confirmed tampered devices in Europe by publication time.
