Coinbase Transparency Under Fire After Delayed Breach Disclosure

Coinbase has faced criticism for its delayed disclosure regarding a customer data breach that took place earlier in the year. While the exchange initially revealed the incident on May 15, 2025, new information suggests the severity and timeline of the breach were known much earlier – potentially even as far back as January. Reuters reports that Coinbase only became fully aware of the extent of the cybersecurity threat after receiving an extortion demand from attackers in late April. This revelation has raised concerns about transparency and timeliness, particularly considering the potential financial and reputational consequences for the exchange.
