Trezor: 3 Safe 5 Devices Found with Hardware Implants

On November 12, a Trezor announcement revealed that the company found three Safe 5 hardware wallets purchased through distributor CryptoBilis contain implants. None of the three device owners suffered any financial loss. One unit has undergone laboratory examination, and the remaining two were identified based on photographs provided by users.

These three devices were purchased between August 20 and September 23, 2026. Trezor stated that no implants were detected in other distributor equipment that had been inspected or in other models. The company released firmware version 2.13.1 on November 11 to block the identified implants from capturing screen content, and announced that it has reduced its distributor network by approximately 80%.

Trezor advised CryptoBilis customers that they should still transfer their funds to wallets created with new mnemonics, as the firmware update cannot protect backups that were compromised beforehand.
