Modern Business Solutions, a data storage and database hosting firm operating on behalf of marketing clients, suffered a large-scale data exposure when a MongoDB database containing roughly 58 million consumer records was shared publicly on social media. The database appeared to have been left accessible without authentication, pointing to a misconfiguration rather than an external intrusion. The company has never publicly acknowledged the incident or explained how it came to hold the data. The exposed records included names, email addresses, dates of birth, genders, home addresses, phone numbers, job titles, and IP addresses. The combination of dates of birth and physical addresses alongside contact details creates serious profiling risk. It provides enough information to support targeted phishing, identity fraud, and social engineering attacks against the people whose data appeared in the database. Modern Business Solutions issued no breach notification and took no publicly documented corrective action. Because the company operated as a backend data host rather than a consumer-facing business, the roughly 58 million individuals in the database had no direct relationship with the firm and would have had no reason to know their data was held there. That lack of visibility makes it harder for affected people to assess their exposure or take protective steps.

Data-hosting and marketing-database firms collect and store consumer, business, client, and campaign-linked records across hosting, storage, and database-management workflows.

Modern Business Solutions has maintained no significant public presence following the 2016 incident. The company has not publicly acknowledged the breach or explained the circumstances of the exposure.
