On October 13, Cointelegraph reported that MediaMarktSaturn, the parent company of European electronics retailer MediaMarkt, has removed all Ledger products from its stores and online platforms, stating that it is in contact with the manufacturer and takes the matter very seriously. X user Johannes claimed that two Ledger wallets purchased from different MediaMarkt stores contained unauthorized cables and cellular modules. Ledger stated that the related implants could transmit user recovery phrases via cellular networks and is investigating reports beyond CryptoBilis. Former Mt. Gox CEO Mark Karpelès claimed that a Ledger Flex he purchased at Singapore airport contained a spy implant; Ledger responded that users should refer to the latest CryptoBilis investigation updates but did not directly address the Singapore case or confirm the existence of tampered devices in Europe.
