Trezor alerts users to potential vulnerability in older Safe 3 wallets.
Trezor has disclosed a possible security issue in Safe 3 wallets after Ledger identified a supply chain attack using voltage glitching.
🔹 The attack requires physical access and advanced skills, making widespread exploitation unlikely.
🔹 Newer models, including Safe 5, are NOT affected.
🔹 Users should buy only from official sources, use strong PINs, enable passphrases, and keep firmware updated.

Trezor has acknowledged a potential supply-chain security weakness in older Safe 3 hardware wallets after research from Ledger’s Donjon team showed that a physical attack using voltage glitching could bypass one of the device’s defenses. Trezor says the issue is not a remote hack, requires physical possession of the wallet, and advanced laboratory skills, which makes large-scale exploitation unlikely. The disclosure matters because hardware wallets are meant to protect private keys even if a device is stolen or tampered with, so any demonstrated bypass of a security layer can affect user trust and purchasing decisions. Trezor says newer hardware, including the Safe 5, is not affected, and it continues to recommend buying only from official sources, using a strong PIN, enabling a passphrase, and keeping firmware updated as part of its broader defense model against physical and supply-chain attacks.
