Hightower Advisors Faces Class Action Over Alleged Data Breach

From the desk of Jim Eccleston at Eccleston Law

Hightower Holding LLC is facing a class action lawsuit alleging that the firm failed to protect sensitive personal information following a data breach affecting thousands of individuals, according to reporting by Financial Advisor News.

The lawsuit, filed in federal court in Illinois by a former employee, claims that Hightower did not implement or maintain adequate cybersecurity safeguards despite collecting and benefiting from individuals' private data. The complaint alleges that this failure resulted in unauthorized access to the firm's systems and exposure of personally identifiable information.

According to Financial Advisor News, the firm identified a compromised account on January 9, 2026, which allowed unauthorized access to its network. An internal investigation determined that between January 8 and January 9, files containing names, Social Security numbers, and driver's license information were downloaded without authorization.

The complaint further alleges that Hightower disclosed the breach more than three months after discovering the incident. A separate filing with the Maine Attorney General indicates that the breach affected approximately 131,483 individuals.

Hightower later identified a second security incident. As reported by Financial Advisor News, the firm discovered another compromised user account on January 19, which also resulted in unauthorized access. Investigators determined that additional files were downloaded between January 19 and January 20.

The firm engaged third-party cybersecurity and forensic specialists to investigate both incidents and to review affected data. Hightower notified impacted individuals after completing that review and offered 12 months of credit monitoring and fraud assistance services.

The lawsuit alleges that the breach exposed affected individuals to ongoing risks, including identity theft and financial harm. The plaintiff claims that he and other class members have suffered damages related to the misuse of their personal information, as well as time spent monitoring accounts and addressing potential fraud. The complaint also cites emotional distress, including anxiety and stress associated with the exposure of sensitive data.

Financial Advisor News reports that this lawsuit follows a separate class action filed earlier in the month against another advisory firm over similar allegations involving data security failures.
