Ledger finds security flaws in Trezor Safe 3 and Safe 5 models

Security Vulnerabilities in Trezor Wallets: Ledger's report reveals significant security flaws in Trezor's Safe 3 and Safe 5 hardware wallets, primarily due to vulnerabilities in their microcontrollers that could allow hackers to gain remote access to user funds despite the introduction of a Secure Element.

Bypassing Firmware Integrity Checks: The authentication system used by Trezor fails to verify the integrity of the microcontroller's firmware, allowing attackers to modify it undetected, which poses a serious risk as compromised devices can appear legitimate while stealing private keys or altering transactions.
