Leading cryptocurrency exchange Coinbase is grappling with the aftermath of a serious cybersecurity breach that could cost the firm up to $400 million, according to a recent corporate filing.
The breach, disclosed just days before the company is set to be added to the S&P 500 index, involved a calculated social engineering attack. Cybercriminals reportedly tricked Coinbase employees and contractors into giving up sensitive customer information by offering bribes. Armed with this data, the attackers then impersonated the company and deceived customers into transferring their digital assets.
Though only a fraction—less than 1%—of the platform’s customer base was affected, the financial and reputational damage is expected to be significant. The company has vowed to fully reimburse victims and announced it is working with law enforcement agencies to bring the perpetrators to justice.
Instead of complying with the attackers' $20 million extortion demand, Coinbase is offering a reward of the same amount to anyone who provides information that leads to the arrest and conviction of those responsible.
The company estimates the financial fallout will range between $180 million and $400 million, primarily due to customer reimbursements and recovery efforts. However, the total impact remains uncertain as investigations and potential legal claims continue.
The breach has also had an immediate financial impact on the company’s stock, which fell by over 4% following the announcement.
Nick Jones, founder of crypto firm Zumo, commented on the situation, saying, “The maturing crypto space is becoming increasingly attractive to sophisticated cybercriminals. Security must evolve with the threat.”
Coinbase confirmed that employees who were found to have disclosed customer information have been dismissed. The company also issued a renewed warning to its users, emphasizing that it never asks for sensitive data like passwords or wallet credentials and encouraging anyone with concerns to lock their accounts immediately.
