READ MORE Researchers did say that though that Socialarks database did include information that wasn't publicly available on user accounts. They said: "Socialarks’ database contained scraped data including personal information, albeit user data was partially completed. "However, according to our findings, Socialarks’ database stored personal data for Instagram and LinkedIn users such as private phone numbers and email addresses for users that did not divulge such information publicly on their accounts. How Socialarks could possibly have access to such data in the first place remains unknown." Safety Detectives said they discovered the database vulnerability last month, and contacted Socialarks as soon as they confirmed the Hong-Kong based firm were the server owners. The server was secured on the same day.
