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.
