Trezor ships firmware update to block tampered Safe 5 wallets
The hardware wallet maker says it found three modified devices and cut its retail network by 80% to close logistics gaps.
Key takeaways
- Trezor said it discovered three Safe 5 hardware wallets that had been physically modified.
- The company released a firmware update intended to neutralise altered devices.
- Trezor reduced its commercial network by 80% to address logistics vulnerabilities.
- The company did not say where the modified devices were found or who altered them.
What Trezor announced
Trezor has released a firmware update for its hardware wallets that the company says neutralises devices altered after leaving its control. According to CriptoNoticias, the maker of the Safe 5 wallet took the step after discovering three units that had been physically modified.
A hardware wallet is a device that stores the private keys controlling crypto assets offline. A device modified before it reaches a buyer can be made to expose those keys, which is why makers treat the physical supply chain as part of their security model.
Retail network cut by 80%
Alongside the update, Trezor reduced its commercial network by 80%, according to CriptoNoticias. The report links the reduction to vulnerabilities in logistics, the path a device takes from production to the customer.
The report does not say which resellers or regions were affected, how many points of sale remain, or when the reduction takes effect.
What is still unclear
CriptoNoticias does not report where the three modified Safe 5 units were found, who altered them, or whether any user lost funds. Trezor has not said publicly, in the material available, whether the firmware update protects only newly purchased devices or also units already in customers' hands.
The report also does not describe how the modification was detected or what the altered devices did differently from factory units.
Updated 13 November 2026
Trezor will remove 80% of its distributors starting January 2027, according to CriptoNoticias.
