Trezor Warns of Suspected Hardware Implant in One of Its Wallets Sold by CryptoBilis

A customer reported finding a suspicious extra circuit board in a Trezor Safe 5 hardware wallet purchased from reseller CryptoBilis, which allegedly sends the recovery phrase over a mobile network. Trezor has not yet inspected the device to confirm the findings. In response, Trezor is advising all customers who bought a Trezor wallet from CryptoBilis since March 2026 to transfer their funds to a new wallet with a new recovery phrase. This warning was issued by Trezor in a blog post, although the company has not yet verified the issue firsthand. The affected wallet's discovery has prompted Trezor to take precautionary measures to protect its customers' assets.
