Trustmark Mutual Holding Company

Trustmark Insurance Company contacted customers regarding a data breach. The company discovered that "our automated billing e-mail system generated and sent encrypted e-mails to certain insurance carrier clients.  While each encrypted email should have contained a single file with information related to each carrier's insureds, on May 14, 2015, we discovered that a software error resulted in each carrier receiving file attachments for all of the carriers instead of just the one file related to their own insureds."More Information: http://oag.ca.gov/ecrime/databreach/reports/sb24-56493
