Key takeaways
- 1Trezor cut its reseller network by about 80 % after the implant report
- 2The Nov 11 firmware update claims to neutralise the Safe 5 implants and no funds have been reported lost
Trezor released a firmware update on Nov 11 that it says neutralises the hardware implants discovered in Safe 5 wallets sold by reseller Cryptobilis. The update is available for all current Trezor models and also disables the compromised communication module.
The company also announced it has cut its reseller network by roughly 80 percent after the implant issue. It reported that no customer has lost funds and that the implants could read recovery seeds and transmit them via a cellular network, a capability Trezor says is now blocked.
Trezor, a Czech‑based maker of cryptocurrency hardware wallets, is one of the longest‑standing providers of offline key storage. In late October it warned users who bought Safe 5 devices from Cryptobilis to move assets after an Indonesian buyer found an unauthorised circuit board inside a device. Hardware wallets like Trezor are widely used by retail and institutional investors to keep private keys offline, making any breach a serious security concern.
The patch aims to restore confidence in the Safe 5 line and signals that the firm is actively addressing supply‑chain risks. Traders and custodians will watch for user feedback on the update and for any further advisories from Trezor or regulators. Observers will also monitor whether other resellers adopt similar security sweeps and whether the incident prompts broader industry checks on component sourcing.
