What Happened?
In January 2025, a breach involving Coinbase’s customer support operations was detected. An employee at TaskUs, a U.S.-based outsourcing firm in India, was found photographing sensitive Coinbase customer data on her work computer. This act was part of a larger scheme where cybercriminals bribed support agents to access and leak personal information, including names, addresses, phone numbers, partial Social Security numbers, and government-issued ID images. Importantly, login credentials, private keys, and access to funds were not compromised.
Upon discovery, TaskUs terminated the involved employees and reported the incident to Coinbase. However, the breach was not publicly disclosed until May 2025, after the attackers demanded a $20 million ransom to prevent the release of the stolen data.
The breach affected approximately 69,000 Coinbase customers, less than 1% of the platform’s user base. Coinbase has since implemented stricter security protocols, including enhanced monitoring of customer support operations and additional safeguards for affected accounts. The company is cooperating with law enforcement to investigate the incident and has offered a $20 million reward for information leading to the arrest and conviction of the perpetrators.
This incident underscores the vulnerabilities associated with outsourcing customer support functions and the importance of robust security measures to protect sensitive user data.
