Ledger Reveals How Hidden Chips Stole Wallet Recovery Keys
Ledger said the implant uses a separate microcontroller and LTE connection, and Bitquery estimated about $102 million in suspected thefts across 324 wallets.
- On Tuesday, Ledger confirmed that an unauthorized hardware implant in devices sold by Southeast Asian reseller CryptoBilis captures users' 24-word recovery phrases and transmits them over LTE networks using an embedded SIM.
- The incident surfaced Friday after cryptocurrency losses were reported involving Ledger devices purchased through CryptoBilis, which operated as an authorized reseller in Indonesia, Malaysia, and the Philippines.
- Inside the device casing, the implant monitors information displayed on the screen during setup, though Ledger stated it does not modify the Secure Element, the chip responsible for protecting private keys.
- CryptoBilis suspended all sales following the findings, while OneKey and Trezor terminated their reseller authorization agreements; blockchain analytics firms estimate potential cryptocurrency thefts range from $86 million to $103 million.
- Customers who purchased signers through CryptoBilis were advised to contact Ledger Support and avoid initializing devices, as the company continues examining hardware and has not verified reports of tampered devices from other channels.
