Your hardware wallet may have been pre-compromised

Hardware wallets bought from unofficial sources (Amazon third-party sellers, eBay, secondhand) may have been tampered with. Scammers buy devices, extract or pre-generate seed phrases, then resell them as "new."

Always buy hardware wallets directly from the manufacturer.

How this attack works

A genuine hardware wallet generates a brand-new seed phrase on first setup that only you ever see. Devices bought from Amazon third-party sellers, eBay, or other resellers can arrive pre-initialized with a phrase the seller already knows — sometimes shipped with a "use this PIN and recovery sheet" card.

Once you fund a wallet whose phrase someone else generated, they can drain it whenever they like. Tampered packaging and "replacement" devices sent after a fake security alert are variants of the same trick.

Warning signs

  • The device came with a pre-filled recovery sheet or a preset PIN.
  • You bought it second-hand or from a third-party marketplace seller.
  • Setup didn't have you generate and write down a fresh phrase yourself.

What to do right now

  • Only buy hardware wallets from official manufacturer websites
  • Never use a hardware wallet that came with a pre-filled seed phrase
  • When setting up, the device should generate a new seed phrase
  • Consider your current hardware wallet compromised
