Trezor Reveals Potential Vulnerability in Older Safe 3 Crypto Wallets ! Trezor disclosed a potential vulnerability in its Safe 3 wallet after Ledger identified a supply chain attack using voltage glitching. The attack requires physical access and advanced skills, making it unlikely for widespread exploitation. Newer Trezor models, including Safe 5, are unaffected. Users are advised to buy from official sources, use strong PINs, enable passphrases, and keep firmware updated.
