Yesterday, California Attorney General Xavier Becerra announced a $17.5 million multi-state settlement with The Home Depot, Inc. regarding a data breach affecting point-of-sale systems at the retailer’s facilities. The breach affected the payment card information of approximately 40 million consumers and 53 million email addresses. The settlement includes both monetary and injunctive relief, pursuant to

The California Consumer Privacy Act (CCPA) went into effect three months ago, on January 1, 2020. Although enforcement by the California attorney general cannot begin until July 1, private plaintiffs have been able to bring claims under the law’s limited private right of action since the beginning of the year.
