Trezor Urges Safe 5 Buyers to Move Funds After Report of Unauthorized Implant

Trezor has warned customers who purchased its Safe 5 hardware wallets from the former authorized reseller CryptoBilis since March to transfer their funds. The warning follows a report from an Indonesian customer who found an unauthorized circuit board inside a Safe 5 bought on Tokopedia in August. The suspected implant could capture screen‑displayed data, including wallet recovery phrases, and transmit it via a cellular network. Trezor’s chief commercial officer, Danny Sanders, said the company had not yet examined the device but treated the report as credible and preferred to warn users pre‑emptively. While Trezor has not confirmed where the tampering occurred, it acknowledged that its existing safeguards—such as seals and packaging—are not sufficient alone. The alert comes after similar incidents involving Ledger wallets sold through CryptoBilis, where an unauthorized implant was confirmed. Trezor has been reviewing its hardware protections and plans to reduce its reseller network.
