Massachusetts Mutual Life Insurance Data Breach Investigation

Turke & Strauss LLP, a leading data breach law firm, is investigating Massachusetts Mutual Life Insurance Company, which does business as MassMutual, regarding its recent data breach. The MassMutual data breach involved sensitive personal identifiable information belonging to an undetermined number of individuals.


MassMutual is an insurance company specializing in offering life insurance packages. Founded in 1851 by an insurance agent who had recently moved from Connecticut to Massachusetts, MassMutual began as a mutual company serving Massachusetts residents. Over time, MassMutual grew by offering high-premium insurance policies to pioneers and laborers going west, spurred on by the California Gold Rush. By the 1980s, MassMutual had decided to reorganize by introducing a new line of life insurance policies and retirement investment services. Today, MassMutual offers term and permanent life insurance products, disability insurance, long term care insurance, and retirement planning services. Headquartered in Springfield, Massachusetts, MassMutual manages over $312 billion in assets and employs more than 11,000 individuals.


Recently, MassMutual discovered that it had experienced a data breach in which the sensitive personal identifiable information in its systems may have been accessed. Through its investigation, MassMutual determined that an unauthorized actor may have accessed this sensitive information. On October 6, 2022, MassMutual began notifying individuals whose information may have been impacted. The type of information exposed includes:

  • Name
  • Social Security number
  • Driver’s license number
  • Passport number
  • Financial information (e.g., account number, credit or debit card number)
