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

By [email protected] (The Hacker News)

AI Summary

A Trezor Safe 5 hardware wallet purchased from reseller CryptoBilis was found to contain an extra circuit board designed to exfiltrate the wallet's recovery phrase over a mobile network, constituting a hardware supply-chain implant. Trezor is advising all customers who purchased from CryptoBilis since March 2026 to immediately transfer funds and generate a new recovery phrase. This represents a rare confirmed hardware-level supply-chain attack against cryptocurrency custody devices, with direct and severe financial risk to affected users.
