American moving rental company U-Haul has started informing 67,000 customers that their personal information was compromised in a data breach.
The incident, the company says, was identified in early December 2023 and involved unauthorized access to a system that allows U-Haul Dealers and Team Members to track reservations and view customer records.
According to the company, an unauthorized party used legitimate credentials to access the system. However, U-Haul has not said how the attackers came by the credentials.
“We initiated our response protocol and a cybersecurity firm was engaged to conduct an investigation. The investigation identified specific customer records that were accessed, including one of your records,” the company notes in the notification letter to the affected individuals, a copy of which was submitted to the Maine Attorney General’s Office.
Responding to a SecurityWeek inquiry, U-Haul confirmed that the incident affected approximately 67,000 customers in the US and Canada and that it is notifying them by mail.
According to U-Haul, the unauthorized party was able to view names, dates of birth, and driver’s license numbers, but did not access financial information.
“The system accessed by the unauthorized party was not part of our payment system. No payment card data was involved,” U-Haul said.
The notification letter sent to customers also reveals that U-Haul determined on December 6, 2023, that personal information was compromised in the attack, but does not explain why the company waited more than two months to inform them of the incident.
“We worked to analyze the customer records involved, and, on December 6, 2023, we determined that your name, date of birth and driver’s license number was accessed by the unauthorized person,” the letter reads.
U-Haul also notes that it has changed the passwords for the affected accounts and implemented additional security measures, and is offering free identity protection services to the affected individuals.
This is not the first time U-Haul customer data has been accessed by hackers leveraging compromised credentials.
