Trezor is telling customers who bought its hardware wallets from CryptoBilis since March 2026 to transfer their funds to a freshly created wallet with a new seed after a buyer reported finding an implant inside a Trezor Safe 5 purchased from the former Southeast Asian reseller, which also sold Ledger devices that were found to have been tampered with. The report says an added circuit board fitted with a cellular module and antenna captures the recovery phrase displayed on screen and transmits it over a mobile network whenever the device is connected. Trezor has not yet verified the claim and no stolen funds have been reported. 1
