Who Is Planting Backdoors in Ledger Crypto Wallets?
Hardware implants in Ledger wallets sold by authorized resellers enabled theft of about $102 million.
Ledger said hardware implants in wallets sold by Malaysian reseller CryptoBilis enabled theft of cryptocurrency now valued at about $102 million from roughly 315 accounts, according to Bitquery. Stolen assets included Bitcoin, Ethereum, and Tron. Users and researchers have also reported implants in Ledger Nano X, Flex, and Stax devices, including two Nano X units purchased in person at MediaMarkt stores in Germany. Joe Grand had notified Ledger of similar Nano X implants in March. Ledger said there is no indication its own infrastructure was compromised and told resellers not to restock returned devices.
