According to PANews, hardware wallet manufacturer Ledger has identified a microcontroller vulnerability in Trezor's Safe 3 and Safe 5 wallets. Trezor quickly addressed the issue, although Ledger's Donjon team noted that potential firmware bypass problems remain despite improved security measures.
In response, Trezor stated on the X platform that their customers' funds remain secure and no action is required. They also clarified that the Trezor Safe 5 is unaffected due to its use of a newer microcontroller, which offers stronger resistance to similar attacks.
