“Coinbase leaked data from 70,000 users”? The company has just come out and refuted part of the claim.

This story has been all over CT this morning. It first appeared in a post by X user @DelCrxpto, who said it was confirmed that Coinbase had been hacked and the contact details of 70,000+ users had been leaked. The Chinese-speaking community soon started sharing it too.

A few minutes ago, the official Coinbase Support account responded. The key points were:
1️⃣ Coinbase has not had a data breach; its own systems were not compromised.
2️⃣ The incident involved third-party data analytics provider Amplitude. Its security incident affected the contact information of “a small subset” of Coinbase users, as well as customers of Amplitude.
3️⃣ Coinbase found no unauthorized access to its systems, and user funds were not affected.
4️⃣ It is notifying affected users and regulators as required by law.

Note: The company has not given a specific number. The figure of 70,000 currently comes only from the original poster, so don’t treat it as confirmed.

My take: “It wasn’t me who got hacked; it was my vendor” doesn’t make much difference to users. It’s still your email address and phone number that were exposed. The real risk is the phishing that may follow—expect more calls, texts, and emails impersonating customer support.

Three ways to protect yourself:
- Hang up on anyone claiming to be support who asks you to transfer crypto, share a verification code, or install software.
- Don’t click links in texts or emails. Open the official website or app yourself.
- Use an authenticator app or hardware security key for 2FA; don’t rely on SMS alone.
