On July 13, MassMutual inadvertently sent a report via secure email that included client information to an incorrect retirement Plan Sponsor.  Client names, Social Security numbers, and 401(k) balance information were exposed.  The individual who received the plan information informed MassMutual of the error immediately and claimed to have deleted the information without storing or printing it.
