Trezor Warns of Hidden Cellular Implant in Safe 5 Wallet

Trezor has warned users about a sophisticated hardware implant discovered in one of its Safe 5 cryptocurrency wallets. The affected device was purchased in August 2026 from CryptoBilis, a Southeast Asian reseller, through the e-commerce platform Tokopedia. According to the responsible disclosure report, the compromised wallet contains a hidden circuit board, an antenna, and a cellular communication module. The components are designed to capture recovery seed phrases directly from the device’s screen and send the information to attackers through mobile networks.
