The US Justice Department has initiated a formal investigation into the recent security breach at cryptocurrency exchange Coinbase Global, focusing on how cybercriminals successfully bribed overseas employees to compromise sensitive customer data.
According to Bloomberg's Monday report, the DOJ's criminal division in Washington is leading the probe into the incident, which involved social engineering tactics directed at the company's customer support infrastructure in India. The breach culminated in an extortion attempt when attackers demanded a $20 million ransom to prevent public release of the stolen information.
Bribed Support Agents Led to Data Theft and Potential $400M Loss
Coinbase disclosed the security incident last Thursday, revealing that the company received an anonymous email from hackers on May 11 containing the ransom demand. The breach occurred when cybercriminals successfully bribed a small number of overseas customer support representatives to extract sensitive data from internal Coinbase systems.
"We have notified and are working with the DOJ and other US and international law enforcement agencies and welcome law enforcement's pursuit of criminal charges against these bad actors," stated Paul Grewal, Coinbase's chief legal officer, in response to the incident.
The cryptocurrency exchange has terminated the employment of the individuals involved in the breach and estimates that the total cost of the incident could reach approximately $400 million. This figure likely accounts for breach notification expenses, customer protection services, regulatory penalties, and potential litigation costs.
Customer Information Compromised While Funds Remain Secure
Coinbase has confirmed that while certain personal information was compromised—including names, contact details, masked Social Security numbers, and bank account information—no customer funds were affected during the breach. The company emphasized that passwords, private keys, and access to digital wallets remained secure, with neither hot nor cold storage wallets being accessed by the attackers.
Coinbase Prime users were also not impacted by the security incident, according to the company's disclosure. In the months preceding the breach, Coinbase had detected suspicious activity involving customer support agents outside the United States collecting data from internal systems and had taken steps to address these instances.
Rather than meeting the ransom demand, Coinbase has focused its response on strengthening security protocols and notifying affected users, while cooperating fully with law enforcement investigations into what represents one of the most significant security incidents in the company's history.
