13 outlets told this the same way.
Amplitude Vendor Incident
Coinbase said a security incident at outside analytics provider Amplitude affected contact information for some customers, while Coinbase said it found no evidence of unauthorized access to its own systems. Coinbase also said no customer assets were harmed and stressed that the incident does not constitute a data breach of its own systems.
Coinbase said it is notifying affected customers and reporting the incident to regulators in line with legal requirements, while it did not disclose how many customers were affected or the specific scope of the information exposed. Coinbase clarified that the incident originated at Amplitude, an external analytics provider, and not within the exchange itself, while Coinbase said its systems have not detected any unauthorized access.
What Data Was Exposed
Coinbase support on X said the incident impacted a “small subset” of Coinbase customers, along with other Amplitude clients, and Coinbase said it is informing affected customers by email as required by law. Coinbase said the exposed data includes only a small subset of contact information, and Cointelegraph reported that Coinbase denied its own systems had been breached while saying customer funds were not affected.
Coinbase did not specify how many customers were affected or exactly which contact data fields were involved, leaving key details unresolved. Around 70,000 Coinbase users may have had their contact details exposed, while Coinbase did not confirm that figure and Bithumb was still checking if customer data was leaked.
Broader Crypto Cyber Risk
CoinDesk connected the disclosure to supply chain risk, saying customers may face security risks through third parties even when a company’s core infrastructure remains secure. Cointelegraph said the disclosure adds to Wednesday’s reports of cyberattacks affecting both crypto exchanges and traditional financial firms, including Daishin Securities reporting a leak of personal and credit information belonging to 38,490 customers.
Daishin Securities reported a data breach affecting 38,490 customers, while Mirae Asset Global Investments detected unauthorized access to some of its web systems and said the incident exposed only internal business data. Bithumb was investigating whether a breach of its internal work platform exposed customer information, while Coinbase said customer funds were safe after the Amplitude incident.
