A MongoDB database was exposed online that contained health care information for 2 million patients in Mexico. This data included information such as the person’s full name, gender, date of birth, insurance information, disability status, and home address.
The database was discovered by security researcher Bob Diachenko via Shodan, which is a search engine for all Internet connected devices and not just web servers. When discovered, this database was fully exposed to the Internet and could be accessed and edited by anyone without a password.
