Coinbase Denies Platform Intrusion as Vendor Data Leak Emerges

Coinbase is facing fresh security questions after a breach at analytics provider Amplitude exposed customer contact information, while unverified claims put the number of affected users above 70,000. The exchange insists its own systems and customer funds remain untouched.
