Researchers tested 50 user records, the records include any education histories and includes only multiple email addresses and multiple phone numbers.

The data found to be originated from two Data Enrichment companies People Data Labs and OxyData.

Analysis with the “Oxy” database revealed that the data sets contain almost complete scrape of LinkedIn data, including recruiter details. Researchers contacted OxyData, and they informed: “that the server did not belong to them.”

Researchers not able to attribute the database to any specific company, they believe the data belong to the customer of both the companies.
