The U.S. Department of Justice (DOJ) has reportedly launched an investigation into Coinbase Global’s contracted customer service representatives in India, following allegations that some agents accepted bribes to grant criminals unauthorized access to user data, leading to multiple social engineering attacks.
Key Points
- The contractors involved have since been terminated
- The breach triggered a wave of social engineering scams aimed at users, causing estimated losses of up to $400 million
- In addition, the perpetrators sought to extort $20 million from the exchange to keep the incident confidential, an offer that Coinbase declined
According to a report by Bloomberg, DOJ investigators are probing a data breach involving customer support contractors who misused their system access to steal account information from a limited number of customers. The contractors involved have since been terminated.
“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,” Paul Grewal, Coinbase’s Chief Legal Officer, stated, according to Bloomberg.
The breach triggered a wave of social engineering scams aimed at users, causing estimated losses of up to $400 million. In addition, the perpetrators sought to extort $20 million from the exchange to keep the incident confidential, an offer that Coinbase declined.
On May 15, Coinbase revealed that the data breach exposed sensitive customer information, including names, addresses, phone numbers, email addresses, masked Social Security numbers (last four digits), masked bank account details, and government-issued ID images like driver’s licenses and passports.

While this breach compromised personal data, investigators confirmed that critical security elements—such as login credentials, two-factor authentication codes, private keys, and access to Coinbase Prime or wallet accounts—remained secure, preventing any unauthorized movement of customer funds.

This incident emphasizes a key tension within the crypto industry’s regulatory environment. Coinbase’s stringent Know Your Customer (KYC) requirements mean users must submit government-issued IDs and detailed personal information, enabling greater transparency and regulatory compliance.
However, when such sensitive data is compromised, it presents heightened risks of identity exposure. Still, the public and immutable nature of blockchain technology offers a powerful counterbalance—since all transactions are recorded on a transparent ledger, suspicious activity linked to stolen data can be tracked and potentially traced back, helping to mitigate some risks associated with data breaches.
