Crypto security firm Unciphered says it has found a way to hack Trezor Model T wallets

Encryption security firm Unciphered said it has found a way to attack Trezor Model T wallets, CoinDesk reported. Unciphered said it exploited an unpatchable hardware vulnerability in the STM32 chip that allowed attackers to dump embedded flash memory and one-time programmable data. Trezor responded that its team did not have enough detail about the specific attack performed by Unciphered to make a full response, but said it looked like an "RDP downgrade attack," a risk that was publicly flagged three years ago.
