Trezor Officially Warns That Safe 5 Devices from CryptoBilis May Have Had Chips Implanted; Owners Urged to Transfer Funds Immediately
The security perimeter of hardware wallets is expanding from software to physical chips.
According to Decrypt, hardware wallet manufacturer Trezor has formally responded for the first time to reports that hardware chips may have been implanted in products sold through a third-party reseller. Trezor advises users who purchased a Safe 5 through CryptoBilis since March to transfer the assets on their devices as soon as possible.
It is worth noting that Trezor says it has not yet physically inspected the devices in question and is treating the reports as credible leads. CryptoBilis is a third-party reseller, not an official sales channel, so the potential impact is relatively limited, primarily affecting products from specific batches sold through a particular channel.
This incident represents a new challenge to the physical security of hardware wallets. In the past, discussions of wallet security have focused mostly on software vulnerabilities, leaked recovery phrases, or user behavior. But if the alleged chip implant is confirmed, the attack would reach directly into the device’s hardware, meaning the final physical barrier protecting private keys could also be bypassed. Together with several recent exchange security incidents and controversies involving key vault products such as Keystone, this has sparked a broader discussion about the security of self-custody.
However, several key factors remain to be seen. First, Trezor has not physically inspected the devices and is currently treating the matter as a credible report; the final conclusion awaits official verification. Second, the reseller involved is a third party, and it is not yet clear whether products sold through official channels are affected. Third, the risk may be limited to specific batches rather than the entire product line.
For owners, the most practical step is to confirm where and when they purchased their device. If they bought a Safe 5 through CryptoBilis after March, they should transfer their assets promptly to reduce uncertainty. For the industry as a whole, how hardware wallets maintain physical security throughout production, shipping, and distribution may become an ongoing area of scrutiny.
Next, watch for whether Trezor publishes formal test results and an official statement, as well as how the reseller involved responds.
