Trezor Warns CryptoBilis Customers of Potential Hardware Fraud

Digital wallet manufacturer Trezor has advised customers of the retailer CryptoBilis to move their assets immediately. The warning follows a report of a Safe 5 device containing a suspicious electronic circuit installed internally.

The case was reported by a user in Indonesia who purchased the device in August through an e-commerce platform. The unauthorized component could potentially capture information displayed on the device screen. Vulnerable data includes wallet recovery phrases, which could be transmitted via cellular networks.

The company has not yet performed a physical forensic analysis on the hardware in question. Nevertheless, the firm is treating the report as credible to prevent user losses while it investigates the origin of the tampering. There have been no reports of fund losses so far.

This incident follows similar reports involving Ledger wallets sold by the same retailer. Trezor admitted that current security seals and packaging do not guarantee full protection against this type of physical modification. The company now plans to reduce its network of authorized resellers to mitigate future risks.

Security flaws in self-custody devices increase the perception of operational risk in the crypto ecosystem. This scenario may boost demand for more transparent storage methods or solutions that do not rely on intermediaries in the supply chain.
