On May 24, 2023, the encryption security company Unciphered announced that they had discovered a method to attack the Trezor Model T wallet, which exploited an unpatchable hardware vulnerability in the STM32 chip, allowing attackers to dump embedded flash memory and one-time programmable data. In addition, the Trezor Model T was also identified by Kraken Security Lab in 2020 as having the risk of being hacked or being able to use seed phrases to expose operations. Therefore, there are some security vulnerabilities in the Trezor Model T virtual currency wallet.

   Despite Trezor's official response stating that they are unable to provide a comprehensive response to the specific attack carried out without proper execution, and mentioning that it appears to be an RDP downgrade attack, a risk publicly flagged three years ago, the existence of these vulnerabilities still poses a threat to user security.

   The Trezor Model T is a highly secure digital wallet. It adopts hardware encryption technology to store users' private keys in offline devices, effectively preventing network attacks and hacker intrusions. Although the Trezor Model T is designed with high security, no device or system can be completely immune to all potential security threats. When using the Trezor Model T, users should ensure that they purchase it from official channels and follow best security practices, such as regularly updating software, using strong passwords, enabling two factor authentication, etc., to maximize the protection of their funds.
