As digital asset security risks continue to evolve, attackers are no longer targeting only trading platforms and user accounts. Hardware wallets can also become an entry point for attacks during procurement, shipping, and delivery.
If a device is intercepted, swapped, or maliciously modified during distribution, it may pose a risk to users’ asset security even if it appears indistinguishable from a legitimate product.
Gate reminds all users that when purchasing and using a hardware wallet, they should look beyond the brand and price. It is equally important to verify the device’s source, delivery channel, and subsequent security checks.
I. What Is Hardware Supply Chain Poisoning?
Hardware supply chain poisoning refers to attackers exploiting vulnerabilities in stages such as device manufacturing, warehousing, transportation, distribution, or delivery to swap, tamper with, or implant malicious components in devices.
For example, a user may purchase a hardware wallet through a legitimate channel, but the device could be intercepted by a third party during shipping or resale. Attackers may modify internal components, tamper with the firmware, or forge packaging and official documentation before delivering the device to the user.
Some attacks may also involve phishing techniques. Attackers may send so-called security notices asking users to install specified software, scan a QR code, or re-import their wallet. Once users enter their seed phrase or private key as instructed, their assets may be at risk of theft.
Kraken Security Labs has publicly disclosed research on supply chain attacks targeting Ledger Nano X hardware wallets, noting that devices may be tampered with before users receive them—for example, by being intercepted during shipping or reaching users through malicious resale channels. As of the article’s update date, public information shows that the Ledger Connect Kit frontend dependency package was subject to a supply chain attack. The confirmed affected versions of ledgerhq/connect-kit are: 1.1.5, 1.1.6, and 1.1.7. These versions contained malicious code designed to induce or replace transactions when users connected their wallets or interacted with DApps, thereby stealing assets.

It is important to note that intact packaging and a device that powers on normally do not necessarily mean the device is safe. Some malicious modifications can be difficult to identify through visual inspection.
II. What Are the Risks of Hardware Supply Chain Attacks?
The core function of a hardware wallet is to help users securely store private keys and sign transactions. If the device itself is tampered with, its original security protections may be compromised.
Malicious components implanted in the device: Malicious components or tampered firmware may interfere with the device’s normal operation, increasing the risks of information leaks and transaction security issues.
Impersonation software that induces actions: Attackers may use fake wallet management software, fraudulent upgrade notifications, or fake customer support guidance to trick users into voluntarily disclosing their seed phrases and private keys.
Loss of control over assets: Once attackers obtain a valid seed phrase or private key, they may restore the wallet on another device and transfer the assets.
Even if users have enabled two-factor authentication for their trading platform accounts, it cannot fully prevent risks caused by tampered hardware devices or leaked wallet credentials. Account security, device security, and private key management must each be properly maintained; they cannot replace one another!
III. How Can You Reduce the Risks?
Purchase devices through trusted channels
When purchasing a hardware wallet, choose the brand’s official website or verified authorized channels whenever possible. Remain cautious of devices with unknown sources, clearly abnormal prices, or unverifiable seller qualifications.
Inspect the device before using it
Check whether the packaging, seals, serial number, and device appearance show any signs of irregularities, and verify the device information through the manufacturer’s official channels. When using the device for the first time, follow the official instructions to complete initialization and firmware verification. If the device has already been initialized, verification fails, or the process appears abnormal, do not rush to import assets.
Protect your seed phrase and private key
Your seed phrase and private key are critical information for controlling the assets in your wallet. No one should ask you to provide this information through chat, email, webpages, or remote assistance.
Whether the other party claims to be Gate customer support, a hardware manufacturer, or security personnel, do not trust requests for your seed phrase or private key. You should also never enter your seed phrase on websites or in software from unknown sources.
Do not install software or update firmware casually
For device connections, software installations, and firmware upgrades, rely on information provided through the manufacturer’s official channels. For unfamiliar links, QR codes, unofficial upgrade packages, or notifications requiring urgent asset migration, verify their authenticity first. Do not act hastily simply because someone claims your account is at risk.
If you detect anything unusual, stop using the device immediately
If the device shows signs of disassembly or modification, firmware verification fails, or initialization is abnormal, stop using it and contact the manufacturer’s official support channels to verify the situation.
If you suspect that your seed phrase or private key has been compromised, use a trusted, unaffected device to create a new wallet in a secure environment, and transfer your assets to a secure address as soon as possible. Do not continue using a device that may have been tampered with to manage assets, and do not enter new wallet credentials on a device suspected of being compromised.
IV. Gate Security Reminder
Hardware supply chain attacks are highly covert, and risks may arise before you even receive the device. Therefore, you should not assume that a device is completely safe based solely on its brand label, intact packaging, or ability to power on normally.
Gate reminds users to carefully verify the source of a device when purchasing and using a hardware wallet, handle unfamiliar notifications with caution, and properly safeguard seed phrases and private keys. When you cannot verify the authenticity of a device, software application, or operational guidance, verify it first before taking action.
Please remember: Use reliable device sources, verify software updates, and never disclose your seed phrase or private key.
By following these basic security measures, you can better reduce the asset risks associated with hardware supply chain attacks.
