Trezor confirms cellular implants in three Safe 5 wallets sold by CryptoBilis, ships firmware that blinds them, and cuts 80% of its resellers
- CryptoBilis buyers (since March 2026): still move funds to a new wallet with a new seed; the firmware can't protect a backup captured before the update. Trezor offers a free replacement.
- Everyone: buy hardware wallets direct from the vendor; beware scammers posing as Trezor offering replacements or refunds.
- Trezor says the implant works the same way as those found in Ledger devices from the same reseller, adapted to the Safe 5 display.
