Massachusetts Legal and Financial Firms Report Data Breach

MJMS Family Office Services LLC and Madden, Jiganti, Moore & Sheridan LLP, two Massachusetts-based firms operating in boutique legal counsel and wealth management, recently reported a data security incident. On July 14, 2026, these organizations acknowledged that their network infrastructure had been compromised, potentially exposing the personal information they stored. This incident affects individuals whose data was entrusted to these specialized legal and financial practices.

Given the nature of their work with ultra-high-net-worth individuals and family offices, these firms centralize an extraordinary volume of sensitive personal and financial dossiers. When such an entity experiences a data breach, the information involved is often highly confidential and valuable to cybercriminals. The unauthorized access to this kind of data creates a particularly high risk for those affected.

The exposure of your personal information through this breach could lead to various forms of identity theft, financial fraud, or other malicious activities. Bad actors might attempt to misuse the compromised data for sophisticated schemes. Remaining vigilant about your accounts and personal records is crucial following such an event.
