In a significant security incident, Coinbase—a leading cryptocurrency trading platform—recently disclosed a data breach affecting nearly 70,000 users. This breach, attributed to "insider wrongdoing," exposed sensitive personal information. Below, we break down how the breach occurred, what data was compromised, and—most critically—the actionable steps you can take to protect yourself from follow-on attacks and identity theft.
Key Takeaways
- The Coinbase breach exposed personal identifiers, financial data, and identity documents.
- Attackers did not gain access to login credentials, private keys, or customer funds.
- Enhanced security measures include withdrawal allowlisting and hardware-based 2FA.
- Proactive identity theft protection (e.g., dark web monitoring, credit freezes) is essential.
What Happened in the Coinbase Breach?
The breach impacted 69,461 users and occurred on December 26, 2024, though detection lagged until May 11, 2025. According to Coinbase’s official statement:
"Criminals targeted overseas customer support agents, offering cash bribes to insiders who copied data for less than 1% of transacting users. Their goal: impersonate Coinbase to trick victims into surrendering crypto. They later attempted a $20M extortion."
Coinbase refused the ransom and established a $20M reward fund for information leading to the attackers’ arrest.
Compromised Data
✅ Exposed:
- Names, addresses, phone numbers, email addresses.
- Masked SSNs (last 4 digits) and bank account details.

Coinbase’s Response

The company is cooperating with law enforcement and pursuing charges against terminated insiders.
