Trezor has issued a warning about a suspected hardware implant in one of its Safe 5 hardware wallets purchased from the reseller CryptoBilis. A customer in Indonesia reported an additional circuit board between the main board and screen, containing a cellular module and antenna, capable of reading the recovery phrase from the screen and transmitting it over mobile networks. Trezor considers the report credible enough to advise all CryptoBilis buyers since March 2026 to move funds to a new wallet with a new recovery phrase, as physical inspection is unreliable and tampered devices may already have exfiltrated sensitive data. This incident follows Ledger's similar findings involving CryptoBilis, and investigations are ongoing without attribution to a specific threat actor.
