Trezor has issued a warning indicating that a potential hardware implant within a Trezor Safe 5 could steal recovery phrases and transmit them via a mobile network This article explores devices october trezor. . The alert applies to all models purchased by CryptoBilis since March 2026, although only one device has been reported.
The March cutoff is a precautionary measure for customer action, not proof that every device sold since then was altered.
[trezor] The added hardware allegedly reads information displayed on the screen, including wallet backups, and transmits it over a mobile network while the device is connected. This makes the screen connection a potential theft risk. Instead of needing to bypass the wallet’s core security, an attacker can capture the recovery phrases when they appear during setup.
Following a separate investigation involving Ledger wallets from CryptoBilis, the warning comes after Ledger discovered unauthorized hardware implants in some of its customers' devices on October 9. Trezor also credited SEAL 911, the Security Alliance’s emergency response service, for helping with the report and customer support planning. Affected Trezor owners should move their existing wallet backup to a new device, obtain a fresh wallet with a new seed, and transfer their funds to it.
Eligible CryptoBilis buyers can reach out to official Trezor Support for a replacement wallet shipped directly or a voucher for a new device.
