Hardware Wallet
A physical device for securely storing cryptocurrency private keys. It uses a dedicated secure chip to isolate private keys, ensuring that keys are generated and signatures are produced in an offline environment. Even if the connected host machine is compromised, the private key is not exposed.
Timeline (last 90 days)
If the firmware is tampered with, an attacker can replace the recipient address or amount before signing, and the secure element will still sign the wrong data.
The spy chip can intercept communication data between the hardware wallet and the computer, or transmit sensitive information outward.
Users need to be wary of devices purchased through unofficial channels and should consider checking device firmware integrity through official verification tools.
Users who have discovered abnormal transactions should transfer their remaining assets to a new wallet as soon as possible.
The core security assumption of a hardware wallet is that the private key never leaves the device.
Hardware wallets remain a safer choice than hot wallets, but safer does not mean absolutely safe.
Security is not only a matter of cryptographic algorithms and chip design, but also a full-chain proposition spanning manufacturing, distribution, and transportation.
Under normal procedures, the mnemonic phrase should be generated by the user during the device's first initialization; if the device comes with a preset mnemonic phrase, that is an explicit danger signal.
Cryptographic hardware wallets should be purchased from official channels or strictly certified authorized distributors in order to avoid supply chain tampering risks.
Supply chain attacks targeting hardware wallets are generally divided into two categories: physical-layer tampering and firmware-layer tampering.
