Coinbase Says Customer Funds Are Safe After a Vendor Incident Exposed Some Contact Data

By Kevin · 2026-10-28 · News

Oct. 28 (CandyPulse) — If you use Coinbase, your crypto is safe, but your inbox may need extra attention. Coinbase says a security incident at Amplitude, a third-party analytics provider, exposed contact details for some customers. The exchange insists its own systems were not breached and customer funds remain safe.

Key takeaways

The incident began at Amplitude, a vendor, not inside Coinbase's systems, the exchange says
Exposed data: email addresses and phone numbers for a "small subset" of customers
Passwords and transaction histories were not compromised, Coinbase says
Coinbase hasn't said how many users were affected; security firm SlowMist reported 70,000+ may be involved
The real risk is phishing: scammers may use the leaked contact details to pose as Coinbase

What was and wasn't exposed

Data	Status (per Coinbase)
Email addresses	Exposed for some customers
Phone numbers	Exposed for some customers
Passwords	Not compromised
Transaction history	Not compromised
Customer funds	Safe
Coinbase's own systems	No unauthorized access

Coinbase is notifying affected customers by email and has reported the incident to regulators. There's no confirmed link between this incident and any unauthorized withdrawals or account takeovers.

How to protect yourself

Coinbase will never call you asking you to move funds or share codes
Never share your password, 2FA codes or recovery phrase with anyone
Don't click links in unexpected emails or texts; open the app directly instead
Turn on a hardware security key or an authenticator app if you haven't already
