Third-party tracking code, used across the internet to track user behaviors on websites, optimize ads, and other purposes, has been grabbing Facebook user information on websites that support logging in through the social media platform, Princeton researchers report.
When users log in to websites using Facebook’s Login feature, trackers can grab Facebook user IDs and in some cases other information such as email address or gender, potentially without the knowledge of the operators of the websites where the trackers are installed, according to the researchers.
“[W]hen a user grants a website access to their social media profile, they are not only trusting that website, but also third parties embedded on that site,” write Gunes Acar, Arvind Narayanan, and Steven Englehardt, a Mozilla privacy engineer who also researches privacy at Princeton.
The researchers identified seven websites that were accessing Facebook user data and found scripts to gather this user information on just 434 of the Alexa top million sites.
