Trezor warns some of its wallets may hide a seed-stealing implant

Trezor warned that Safe 5 hardware wallets sold by reseller CryptoBilis may contain a hidden circuit board implant that reads the device display and transmits recovery phrases over a cellular network; buyers from March 2026 onward are advised to move funds and not to set up affected devices. The report cites a credible customer disclosure from Indonesia and references earlier, related Ledger device implants and drained wallets in Southeast Asia, prompting reseller removal and tighter security checks.
