What happened
Coinbase has said a security incident at Amplitude, a third-party vendor, affected some customer contact data. Coinbase says its own systems were not compromised, and reports say it told customers their funds are safe. The sources we have do not say exactly what data fields were exposed or how many people were affected.
Who is affected
Some Coinbase customers whose contact data was held by Amplitude. The sources do not say how many people are affected or how to tell if you are one of them, so assume you could be a target for scam messages.
What to do now
- Treat any unexpected message claiming to be from Coinbase as suspect, whether it is an email, text or phone.
- Do not click links or call numbers in messages. Open the official Coinbase app yourself or use your own saved bookmark.
- Remember that Coinbase will never ask you to move funds to a 'safe' wallet or share your recovery phrase or 2FA codes.
- Review your Coinbase account activity and security settings for anything you do not recognize.
- Turn on passkeys or an authenticator app instead of SMS for two-factor authentication.
- Change your Coinbase password if you reuse it anywhere else.
Our alerts never ask you to click a link, log in, "verify" a wallet or move funds. Expect scammers to copy this news: if a message about it asks for any of that, it's a scam.
