MedicareSupplement.com, an insurance marketing website that assists users in finding supplemental medical insurance, has experienced a breach of approximately five million records. The unsecured MongoDB database is linked to the company’s marketing leads and was quickly secured upon notification. Compromised information includes full names, postal and email addresses, dates of birth, gender, phone numbers, and IP addresses. Nearly 239,000 of these exposed records included areas of interest, such as cancer insurance. Users affected by this breach could potentially become targets of social engineering schemes in the future.
