Ledger is facing a class action lawsuit over its 2023 data breach, with plaintiffs alleging the company downplayed the incident’s severity and failed to disclose it in a timely manner. The complaint says the December 2023 security incident exposed customer data including names, email addresses, and phone numbers. Plaintiffs allege hackers used the leaked information to impersonate Ledger and trick users into approving fraudulent transactions, with the data later circulating on darknet and black markets. The filing also points to Ledger’s 2020 leak affecting about 270,000 customers, arguing the latest incident reflects a pattern of negligent, reckless, and irresponsible security practices. Claims include alleged violations of New York State business law, negligence, and negligent misrepresentation.
