Foundation Devices (makers of Passport) reported on Oct 25-26, 2026 that its website and email had been compromised and phishing emails were going out to customers and mailing-list subscribers. Some of those emails included the recipient's full name and postal address. This checklist applies to any hardware-wallet vendor incident.
The one rule#
No real vendor, support agent, "recovery tool" or "migration" ever needs your seed words. If anything asks you to type your 12/24 words into a website, an app on your computer, a form or a chat, that is the attack. The words go only into the signing device itself, and only when you are restoring.
Why this incident is nastier than usual#
- The sender can look perfectly legitimate. When the vendor's own mail system or website is compromised, phishing mail can pass SPF/DKIM and link to the real domain. "It came from their real address" proves nothing during an incident.
- The leaked data lasts for years. Name + email + postal address enables follow-up attacks by SMS, phone and paper mail. After Ledger's 2020 customer-data leak, victims got threatening emails and texts for years, and some received tampered "replacement" devices by post. Treat any unsolicited replacement device, "urgent firmware migration" or "account verification" as hostile.
Firmware#
- Update only through the path in the vendor's official documentation, and wait until the vendor confirms the incident is resolved.
- Good devices check the firmware signature themselves. Never install a firmware file from a link in an email.
What to do if you already interacted#
- Clicked but entered nothing: probably fine. Close the tab and clear site data. Watch for follow-up messages.
- Entered a PIN or password on a website: change it wherever you reused it.
- Entered seed words anywhere other than the device: assume the funds are gone unless you move them first. On a clean device, create a new seed (never re-use the exposed one) and sweep everything to it immediately. Attackers sweep in automated batches, so minutes matter.
Reduce future exposure#
- Buy with an email alias and, where you can, without linking your real address to the purchase.
- Add a BIP39 passphrase. A leaked seed alone is then not enough.
- Check haveibeenpwned for your email once a dump appears, so you know what the attackers have.
