Trezor investigates reported hardware implant in device sold by former reseller
Trezor said it received a credible disclosure describing an extra circuit board inside a Safe 5 bought from former reseller CryptoBilis.
Trezor disclosed a report of a possible hardware implant in a Safe 5 purchased from former reseller CryptoBilis in Southeast Asia. The company said it had not yet received the device for laboratory confirmation when it published the notice, but considered the report credible enough to warn customers. The described implant allegedly used an additional circuit board and communications hardware. Trezor said no customer losses had been reported in connection with the disclosed device. The case follows broader concern about physical tampering in hardware-wallet distribution channels and underlines why device provenance and reseller controls matter alongside firmware security. Avenor News is reporting the disclosure as a security incident and not as a recommendation for or against any wallet product.
