Bad month for security people in companies dealing with email marketing campaigns.

On Monday morning, Sept 17th, I have discovered a huge customer database containing 11 million records that included personal details, such as email, full name, gender, physical address (zip code, state, city of residence).

The data was available from an unprotected MongoDB instance set up on Grupo-SMS hosting infrastructure, and could be accessed by anyone from Sept 13th on (when Shodan last indexed it).

The 43.5GB large dataset contained 10.999.535 email addresses, all Yahoo-based. Apart from customer personal information, the database also included DNS details about the email status (sent successfully or not), that showed if the email went through, and server response.

All Yahoo based? Then Yahoo must be selling them.
