Trezor Issues Safe 5 Warning as Hardware Implant Raises Security Concerns
Trezor warned customers who bought hardware wallets through reseller CryptoBilis from March 2026 onward to transfer their funds to a newly generated wallet. The warning followed a report that a Safe 5 device contained an alleged hidden circuit board with a cellular module that could capture recovery phrases displayed on the device. Trezor has not examined the reported wallet physically, but said the disclosure was credible enough to act on and is offering replacement devices. It has inspected four other returned CryptoBilis devices without finding tampering. No losses tied to the alleged Trezor incident have been reported. Trezor had previously removed CryptoBilis from its authorized network after reports of tampered Ledger devices; Ledger has confirmed tampering, while claims of more than $86 million in losses remain unconfirmed by the company.
