The Coinbase Offers $20M Bounty to track down perpetrators behind a data breach orchestrated by rogue customer service employees. Revealed on May 15, 2025, the incident involved insiders leaking sensitive user information, prompting a swift response from the leading crypto exchange. This article explores the breach details, Coinbase’s countermeasures, and its impact on the blockchain industry.
A Breach Fueled by Insider Betrayal
Coinbase Offers $20M Bounty following a security lapse where overseas customer service staff were bribed to steal user data. The breach, first flagged by on-chain investigator ZachXBT in March 2025, exposed vulnerabilities that may have led to $300 million in user losses over three months. Initially silent, Coinbase confirmed the incident, noting that less than 1% of its monthly active users were affected.
The stolen data included names, addresses, emails, phone numbers, partial Social Security numbers, obscured bank account details, identity documents, account balances, transaction histories, and internal documents. Crucially, no passwords, 2FA codes, private keys, or funds were compromised, and Coinbase Prime accounts and hot/cold wallets remained secure. The breach underscores the growing threat of insider attacks in the crypto exchange sector.
Rejecting Extortion and Fighting Back
Coinbase Offers $20M Bounty after refusing a $20 million Bitcoin ransom demanded by the attackers, who threatened to leak sensitive user data. Instead of complying, Coinbase launched a bold counteroffensive, offering the same amount to anyone providing information leading to the arrest and conviction of those responsible. The company fired the implicated employees and is collaborating with U.S. and international law enforcement to pursue criminal charges.
This decisive stance reflects Coinbase’s commitment to user trust and security, setting a precedent for how crypto exchanges handle extortion attempts. Online discussions praise Coinbase’s transparency. However, some users raise concerns about the scale of potential losses. According to an SEC filing, remediation and compensation may cost between $180 million and $400 million.

Coinbase’s Robust Response Plan
Coinbase Offers $20M Bounty alongside a comprehensive action plan to mitigate the breach’s impact:
- Compensation: Coinbase will reimburse users for verified financial losses, with assessments ongoing.
- Enhanced Security: Affected accounts now require additional verification for large withdrawals and display anti-phishing alerts.
- Internal Safeguards: New U.S.-based support centers, advanced monitoring, attack simulations, and anti-insider threat tools are being deployed.
- On-Chain Tracing: Collaboration with blockchain analytics firms to flag suspect wallet addresses and recover assets.
- Transparency: Notifications sent to impacted users, with ongoing updates promised.
Coinbase urges vigilance against impersonation scams, emphasizing that it never requests passwords, 2FA codes, seed phrases, or fund transfers to new addresses. Recommended security steps include enabling withdrawal allowlisting and using hardware security keys for 2FA. Users should also lock their accounts if they detect suspicious activity. Additionally, they should report any issues to Coinbase’s security email.
Lessons from Past Breaches

Coinbase Offers $20M Bounty in a move reminiscent of a 2021 incident, where hackers stole user data and demanded $450,000. That event also led to a bounty program, highlighting Coinbase’s proactive approach to cybercrime. The latest breach reinforces the need for robust insider attack defenses across the blockchain industry, especially as scams proliferate.
The incident could spur stricter regulations and greater scrutiny of crypto exchanges. While Coinbase’s swift response mitigates immediate fallout, the $180–$400 million cost estimate underscores the financial stakes. Community sentiment, as seen online, balances appreciation for Coinbase’s actions with calls for stronger preventive measures.
Conclusion
Coinbase Offers $20M Bounty to combat a data breach caused by insider attacks, rejecting a $20 million ransom and prioritizing user protection. With a $180–$400 million remediation plan, enhanced 2FA security, and partnerships to trace culprits, Coinbase reinforces its leadership in the crypto exchange space. This incident highlights the evolving challenges in the blockchain industry, urging platforms to fortify defenses and maintain user trust.
