MML Investors Services Data Breach Class Action Investigation

At Console & Associates, our data breach lawyers are closely examining the recent MML Investors Services LLC, a subsidiary of MassMutual data breach. This data breach was disclosed following a cyber security incident at National Financial Services LLC (NFS), which handles clearing and execution services for MML Investors Services' brokerage accounts. While the exact number of affected individuals has not been publicly disclosed, the breach potentially exposed sensitive personal identifiable information of MML Investors Services clients.

What Happened?

A recent report from the Massachusetts Attorney General's office reveals that unauthorized access to NFS's computer network occurred between August 17 and August 19, 2024. The data breach seems to have been facilitated through two recently opened Fidelity brokerage accounts, suggesting a sophisticated approach to gaining access to sensitive client information. The compromised information varies by individual, with specific details being provided in personalized notification letters to affected clients. While the exact nature of the exposed data has not been publicly disclosed, financial account information typically includes:

• Personal identification details
• Account numbers and financial data

Data breach letters were sent out by National Financial Services to inform affected individuals about the nature of the incident and specific data compromised in their case.
