Trezor urged people who bought its wallets from CryptoBilis from March 2026 onward to move their funds to a new wallet with a new recovery phrase. The company said it had received a credible report of an implant in one Safe 5, but had not yet examined the device or verified the reported implant.

A customer in Indonesia reported an alleged implant in a Safe 5 bought from CryptoBilis through Tokopedia in August 2026. Trezor said it had not yet received the device for examination.
The report describes a circuit board with a cellular module and antenna that allegedly reads the device screen, including the wallet backup, and sends the information over a mobile network. Trezor said the report was unverified.
Trezor advised CryptoBilis customers who bought its wallets from March 2026 onward to create a new wallet and recovery phrase, transfer their funds, and not reuse the old phrase. It said no CryptoBilis buyer had reported a loss of funds to the company.
