Implanted chips in Ledger hardware wallets

On 15 October Ledger confirmed that a criminal group had fitted genuine hardware wallets with parts that capture the recovery phrase during setup, then put them on the market through resellers in Southeast Asia. As of 13 October, the thefts Ledger had confirmed were all tied to devices sold by authorised reseller CryptoBilis, and reports of implants from other channels were unconfirmed. Ledger's Genuine Check cannot detect these implants, and Ledger advises anyone who bought and set up a device from CryptoBilis to move their assets to a new device and a new recovery phrase.

The passkey attestation debate

On 10 October a commentary argued against using passkeys because sites can use attestation to restrict which devices and software people may use, and on 14 October an author published a response. Both agree that passkeys are, in most cases, bound to a domain and resist phishing; they disagree on whether attestation will become a restriction, and on whether to keep using passkeys or switch to something else.

Firefox 157 for desktop, released on 29 September, shows a warning when the computer is set up to record encryption keys. Mozilla's support page says antivirus or security software is the most likely cause and the warning does not mean the computer is infected. If sites fail to load, check that software's HTTPS scanning first.
