Hightower Holding Data Breach Impacts 130,000

Hightower Holding, the parent company of financial management services provider Hightower Advisors, is notifying over 130,000 individuals of a data breach, with 131,483 affected according to the Maine Attorney General’s Office. The company said hackers exfiltrated certain files from its environment between 8 January and 9 January 2026, and that the stolen data included names, Social Security numbers, and driver’s licence numbers.

Hightower states the breach resulted from compromised user credentials rather than a deficiency in its environment, and according to the company there is no indication that information has been used to commit identity theft or fraud. SecurityWeek has not seen any extortion groups claiming responsibility for the incident. The firm is offering 12 months of free identity theft and credit monitoring services to the impacted individuals. Written by Ionut Arghire for SecurityWeek.
