Trezor

Hardware wallet products such as Trezor and the early Ledger Nano are based on trimmed systems like RTOS, so they have a small attack surface, low power consumption and fast startup, but weak interaction capabilities, usually able to complete all operations only with two or three physical buttons and a small monochrome screen.

Combining hardware wallets from different manufacturers (for example, Ledger + Trezor + Coldcard) to build a multisig strategy can mitigate the trust risk associated with a single vendor.

Attackers obtained user contact information through the email service provider and subsequently launched targeted scam activities against Trezor wallet users.

Trezor confirmed that a data breach occurred at its dependent email service provider, exposing the information of hundreds of thousands of cryptocurrency holders.

The mnemonic phrase for a Trezor device should only be generated and used locally on the device and should never be entered into any website or email form.

Trezor is a hardware cryptocurrency wallet manufacturer whose core security design includes offline private key storage and physical transaction confirmation.

The source of this data breach was Trezor's partner email service provider, not Trezor's own systems.
