The profile details of over 100 million Facebook users have been made available on an internet file-sharing site, tech new site Thinq has reported.
Security researcher for Skull Security Ron Bowles used a piece of code to scan and collect all user profiles data contained in the platform's open access directory. The directory is a list of all users who have not changed their privacy settings to make their profiles unavailable to search engines.
Bowles said that he had revealed the profiles to highlight the lack of security on the platform.
Facebook has said that the information leaked online is already available online via search engines like Bing, Google and Yahoo, and so is not a reflection of the site's security.
In a statement to the BBC, Facebook said: "People who use Facebook own their information and have the right to share only what they want, with whom they want, and when they want."
"In this case, information that people have agreed to make public was collected by a single researcher and already exists in Google, Bing, other search engines, as well as on Facebook. No private data is available or has been compromised."
The list has been downloaded by over 1000 users of the file sharing website The Pirate Bay since its release. Experts have predicted that thousands more will download the file in the next few days.
