Ledger Donjon Security Research Team Discloses that the TROPIC01 chip used in Trezor Safe 7 has a hardware vulnerability that can bypass the firmware verification system through precise laser attacks in a laboratory environment. Trezor states that user funds, wallet backups, and private keys are not stored on the chip, and user funds are unaffected. Tropic Square claims that all deployed production TROPIC01 chips are affected and has identified another potential attack vector that could impact the MAC-and-Destroy security mechanism; the hardened version of the chip is expected to be released by the end of 2026, with full technical details anticipated to be disclosed in spring 2027.
