U.S. rental company U-Haul was slapped with a class action lawsuit involving a data breach beginning in 2021. Morgan & Morgan, the country’s largest injury law firm, filed the complaint in the U.S. District Court for the District of Arizona last week.

The plaintiffs allege that the company practiced inadequate information security methods that resulted in customers’ personal identifying information being compromised. They also claim U-Haul failed to notify victims of the breach in a timely manner.
