Known Issues
2023: Secure element philosophy shift
Trezor's adoption of a certified secure element in the Safe line led to discussion among open-source advocates because older Trezor models intentionally avoided closed secure elements.
2020: Voltage fault injection extraction on older Trezor models
Researchers demonstrated physical extraction attacks against older Trezor devices without secure elements; Safe 3 adds a secure element to improve resistance against similar physical-access threats.
