Facebook filed a lawsuit today in Portugal against two Portuguese nationals for developing browser extensions that scraped user data from Facebook sites.
“When people installed these extensions on their browsers, they were installing concealed code designed to scrape their information from the Facebook website, but also information from the users’ browsers unrelated to Facebook — all without their knowledge,” Jessica Romero, Facebook’s Director of Platform Enforcement and Litigation, said today.
“If the user visited the Facebook website, the browser extensions were programmed to scrape their name, user ID, gender, relationship status, age group and other information related to their account,” Romero said.
All extensions were developed by a software company named “Oink and Stuff,” specialized in creating Android apps and browser extensions for Chrome, Firefox, Opera, and Microsoft Edge.
While the company develops a wide array of browser extension, Facebook said it found data collection-related malicious behavior inside four extensions named Web for Instagram plus DM, Blue Messenger, Emoji keyboard, and Green Messenger, which Facebook said “functioned like spyware.”
All four extensions are still available on the official Chrome Web Store at the time of writing, and have more than 54,000 installs, combined.
Facebook is now asking a Portuguese judge to issue a permanent injunction against the Oink and Stuff team and force the company to delete all the Facebook user data they acquired through the four extensions.
A request for comment has been sent to Oink and Stuff but the company has not replied before this article’s publication due to timezone differences.
Today’s lawsuit marks Facebook’s latest lawsuit against rogue app and extension developers. Since early 2019, Facebook’s legal department has been filing lawsuits against several third-parties that have been abusing its platform, such as:
