Hardware wallet maker Trezor has confirmed that only three Trezor Safe 5 devices were tampered with in a hardware implant incident, all purchased through reseller CryptoBilis between August and September 2026. No user funds were lost, and no implants were found in devices from other resellers or other Trezor models. On November 11, Trezor released firmware version 2.13.1, which blocks the discovered implant from capturing screen content including seed phrases and private keys, rendering the current batch of implants ineffective. The company also cut approximately 80% of its reseller network and imposed stricter supply chain controls on remaining partners. Trezor advises all CryptoBilis buyers who purchased devices from March 2026 onward to migrate funds to a new wallet using a fresh seed phrase and contact support for a free device replacement. The investigation remains ongoing.
