This bounty aims to encourage information sharing that could lead to arrests and the recovery of stolen data. Investigators are now working with international authorities to trace the cybercriminals’ activities.The exchange opened a new U.S.-based support hub to centralize and tighten customer service operations. The hub applies improved security protocols and limits access to sensitive user information. All customer support teams now operate under stricter monitoring to prevent further infiltration.Users affected by social engineering attacks linked to the breach can now file claims for reimbursement. Coinbase pledged to compensate customers who were deceived into sending funds under pretenses. The company continues to update users as its investigation progresses.Global Context and Ongoing Threats to Crypto SecurityThe exchange breach comes shortly after Telegram cracked down on the darknet marketplace Haowang Guarantee, highlighting a broader cybersecurity threat. As hacking techniques evolve, exchanges like Coinbase face increasing pressure to upgrade defenses and protect customer data. The crypto sector remains a key target for organized cybercrime.Coinbase emphasized that despite the breach, no user funds were stolen and no private account access was compromised. The company maintained full control over financial assets and prevented attackers from accessing wallets. All account activity logs are being reviewed for further anomalies.In 2024, WazirX, another major exchange, suffered a larger breach involving a $230 million theft, forcing operations to halt. That incident remains unresolved, drawing comparisons with the exchange breach. However, the exchange retained operational continuity and has committed to full transparency and customer protection.Also Read: Coinbase Makes History as First Crypto Company to Join S&P 500 The post Coinbase Hit by Insider Breach as Hackers Demand Ransom for Data appeared first on CoinCentral.
