🔐 Even a hardware crypto wallet can turn out to be a spying device.
Trezor reported discovering a suspicious implant in a Trezor Safe 5 hardware wallet purchased from the CryptoBilis reseller in August 2026.
According to the device description, it contained an additional board with a cellular module and antenna. It could read information from the screen, including the seed phrase, and transmit it over a mobile network.
⚠️ Important caveat: Trezor has not yet received the device itself for laboratory testing, but considers the report serious enough to warn customers.
The company recommends that anyone who purchased devices from CryptoBilis since March 2026 transfer their funds to a new wallet with a completely new seed phrase. Customers are also being offered a replacement device or a compensation voucher.
A hardware wallet alone does not guarantee security. The weak link may be not the software, but the supply chain and the seller.
It seems the crypto industry will need to rethink how devices are vetted before they reach customers.
In the meantime, keeping your funds safe remains the responsibility of the owner.
