Ledger faces $500M class action lawsuit over data breaches and customer crypto theft

Crypto wallet maker Ledger has been hit with a $500 million class action lawsuit alleging the company failed to prevent multiple data breaches and adequately protect customers. Plaintiff Douglas Kim claims he lost $1.9 million after attackers exploited compromised customer data from a December 2023 breach, with a former employee's lingering access enabling malicious code injection.
