Ledger's Donjon security research team has identified a hardware vulnerability in the TROPIC01 chip used in Trezor's Safe 7 hardware wallet. The flaw allows attackers with physical access to bypass firmware verification and install unauthorized firmware using laser fault injection in a controlled lab setting. Despite the discovery, Trezor assures users that their funds remain secure, emphasizing that the attack requires specific conditions unlikely to be encountered in real-world scenarios.
