Coinbase Hit with Class-Action Lawsuit Over Data Breach and FCA Violation
Coinbase faces a new class-action lawsuit over a $20M data breach and undisclosed UK regulatory violations, causing stock volatility.
The lawsuit alleges Coinbase withheld key risk info, impacting investors who bought shares between April 2021 and May 2025.
Coinbase is under fresh legal fire, this time from investors. Shareholder Brady Nessler filed a proposed class-action lawsuit on May 22, claiming the crypto exchange’s recent data breach and a regulatory violation with the UK’s Financial Conduct Authority (FCA) triggered a sharp stock decline, causing financial harm to shareholders. Nessler asserts that Coinbase withheld vital information that would have impacted the company’s stock value.
Breach and Extortion Scandal
The data breach occurred months earlier, but was only revealed on May 15, 2025, after Coinbase was targeted by cybercriminals in a $20 million extortion attempt. The attackers bribed overseas customer service agents to gain access to internal systems and steal sensitive user data, including names, addresses, and IDs. Although the company claimed that less than 1% of its monthly active users were affected, the late disclosure led to a 7.2% drop in Coinbase (COIN) shares, closing at $244 on the same day. While the stock rebounded to $266 the next day, it later dipped again, closing at $263 on May 23. Despite these fluctuations, COIN remains up nearly 6% in 2025.
UK Regulator Violation Adds to Fallout
Moreover, the lawsuit also highlights a $4.5 million fine from the FCA in July 2024. The UK regulator found Coinbase had violated a 2020 agreement by onboarding over 13,000 high-risk users. Nessler claims Coinbase failed to disclose this violation when it went public in 2021, artificially inflating its share price.
Coinbase in Legal Scoops
The class-action suit seeks damages for anyone who bought Coinbase stock between April 14, 2021, and May 14, 2025. CEO Brian Armstrong and CFO Alesia Haas are also named as defendants. In addition, Coinbase faces at least six other lawsuits tied to the breach, including one filed in Illinois accusing the company of mishandling users’ biometric data without proper notification.
Coinbase has not responded publicly to the latest lawsuit.
