Mitigating the Risks: Best Practices for Firmware Updates

The biggest potential risk to using a hardware wallet is a supply chain attack. These attacks are possible even before the device reaches you. This is why it’s so important to buy wallets directly from known, reputable manufacturers and avoid untrusted third parties.

  1. Research the Manufacturer: Before purchasing a hardware wallet, thoroughly research the manufacturer's security reputation and track record. Look for companies with a strong commitment to security and transparency.
  2. Verify Updates: Always verify the authenticity of firmware updates before installing them. Check the manufacturer's website or official communication channels for information about the update and its purpose.
  3. Use Official Channels: Only download firmware updates from the manufacturer's official website or through the hardware wallet's official software. Avoid downloading updates from third-party sources, as they may be malicious.
  4. Checksums and Signatures: Verify the checksum or digital signature of the firmware update to ensure that it has not been tampered with. The manufacturer should provide this information on their website.
  5. Read Release Notes: Carefully read the release notes for each firmware update to understand the changes it includes and any potential risks.
  6. Backup Your Seed Phrase: Before updating your firmware, always back up your seed phrase. This will allow you to recover your funds if something goes wrong during the update process.
  7. Test with Small Amounts: After updating your firmware, test the wallet with a small amount of cryptocurrency to ensure that it is working correctly.
  8. Stay Informed: Stay informed about security vulnerabilities and best practices by following reputable security blogs, forums, and social media channels.

Avoid purchasing used or third-party wallets, as these devices may have been compromised or preloaded with malicious software. An attacker would just have to intercept a wallet during shipping, install modified firmware, and then sell the wallet on to an unsuspecting user. At that moment, the user loads their cryptocurrency onto the wallet, at which point the attacker can transfer their funds as well.

The Importance of Secure Supply Chains

To lower this risk, purchase hardware wallets directly from the manufacturer. To avoid fraud altogether, you can pick authorized retailers with strong customer satisfaction history like []. Don’t purchase from online marketplaces or unverified third-party sellers.

Transparency and regular, independent security audits are key for building trust in hardware wallet firmware. One-time audit by independent experts can review and certify the firmware before the device is released, ensuring users' confidence in its reliability.
