Chicago-based Hightower Holding LLC confirmed a significant data breach exposing 131,483 Americans to potential identity fraud.
Unauthorized access via compromised credentials occurred in early January 2026. Hackers downloaded sensitive files containing Social Security numbers and driver’s license details from the corporate network. The investigation revealed the intrusion began around January 9.
The firm notified the Maine Attorney General upon discovery on March 12. Direct notifications reached affected victims by March 23. Regulators are now monitoring the situation for further fallout.
