Massachusetts Mutual Life Insurance Company (MassMutual) has disclosed a data breach that affects individuals in Indiana. The breach, which occurred on April 7, 2025, involved the exposure of sensitive personal data, leading to a report filed on February 13, 2026.
The compromised information includes individuals' Full Name, Social Security Number, Date of Birth, Financial Account Number, Routing Number, Policy Number, Credit Score Information, Transaction History, Mailing Address, and Beneficiary Information. This combination of data types carries significant risks, potentially exposing affected individuals to identity theft and various forms of financial fraud.
