Trezor confirms malicious hardware implants in Safe 5 wallets sold by CryptoBilis, issues firmware fix
Trezor has confirmed that three Safe 5 cryptocurrency hardware wallets sold by Southeast Asian reseller CryptoBilis contained malicious hardware implants designed to steal wallet recovery phrases and transmit them to attackers over cellular networks. The implants are additional circuit boards installed between the main board and display, capturing sensitive information without altering the device’s legitimate firmware or Secure Element. Although no funds have been reported stolen, Trezor released firmware version 2.13.1 with protections that prevent the implants from capturing data on updated devices. Customers who purchased devices from CryptoBilis since March 2026 are advised to transfer their cryptocurrency to new wallets as a precaution. Following these supply-chain attacks, Trezor has reduced its global reseller network by about 80%, imposing stricter sourcing and storage controls.
