Coinbase Data Breach: Delayed Disclosure Sparks Concerns

Coinbase Data Breach: A Timeline of Delayed Disclosure

A Reuters report reveals that cryptocurrency exchange Coinbase was aware of a significant data breach involving its outsourcing partner, TaskUs, as early as January 2025. However, the public disclosure of this breach wasn't made until May 2025, raising serious concerns about transparency and data security practices.

Key Findings

• Delayed Disclosure: Coinbase delayed informing the public about the data breach for several months.
• Bribery and Data Theft: The breach stemmed from a TaskUs employee in India who allegedly leaked customer data in exchange for bribes.
• Impact: The breach affected over 69,000 users, according to a recent Coinbase filing.
• Financial Implications: Coinbase projected potential costs of up to $400 million related to the breach.

The TaskUs employee, along with a suspected accomplice, allegedly shared Coinbase customer data with cybercriminals. This action followed the termination of over 300 TaskUs employees in Indore, India, earlier in the year due to project closure and allegations of fraud. While TaskUs confirmed the termination of two employees involved in illegally accessing client information, it was later confirmed that this referred to the Coinbase data breach.

Coinbase's own $20 million reward program to identify and prosecute those responsible for the breach brought the incident to light. While the company claims that passwords, private keys, and customer funds were not compromised, the significant delay in disclosure and the scale of the breach underscore the severity of the incident.

The SEC disclosure in May highlighted that Coinbase had identified instances of contractors accessing employee data without a business need in previous months but only recognized these events as a broader extortion campaign after receiving an extortion demand on May 11.

Coinbase has stated that it has since severed ties with the implicated TaskUs personnel and other overseas agents, and has tightened security controls. The company is fully cooperating with the US Department of Justice and other law enforcement agencies in their ongoing investigation.
