Malicious Google Chrome extension is spreading nude celebrity sex tape PDFs on Facebook. If users click on the link, they are redirected to a fake YouTube page that leads up a pop-up window inviting victims to install a Chrome extension to view the videos. Once installed, the malware would force web browsers to display aggressive advertising web pages with nudity and fake lotteries. The extension has since been removed by Google’s security team, but users can’t access the Chrome Extensions settings page to disable the add-on.
