Trezor warns CryptoBilis buyers to move funds over suspected implant
Summary
Trezor urged customers who bought wallets through former authorized reseller CryptoBilis since March to move their funds after an Indonesian customer reported a suspected circuit-board implant in a Safe 5 purchased in August. The implant may capture screen data, including recovery phrases, and send it over cellular networks. Trezor has not examined the device and has no reports of related losses, but says it is treating the warning as credible and reviewing its hardware protections. It has not determined where tampering occurred. The alert follows confirmed tampering in a Ledger device sold through CryptoBilis and earlier reports of modified Trezor wallets bought from unauthorized sellers. Trezor plans to reduce its reseller network.
