Many Chrome and Edge browser extensions are infected with malware and affecting users around the world.
According to the Avast threat researcher, many third-party browser extensions for services like Facebook, Instagram, and Vimeo are infected with several types of malware. They found the above malware in 28+ extensions for Google Chrome and Microsoft Edge.
Since these are quite popular extensions associated with major platforms like Facebook and Instagram, Avast announces that no less than 3 million users have installed them on their browsers. Most of these add-ons are designed to help users download videos from popular websites like Facebook and Video, which is a fairly essential need of social media users, so exploiting attacks also becomes easier.
Avast believes attackers are being paid per user they redirect to a malicious website. The company also publishes a list of malicious extensions that you should uninstall immediately, which can be found at https://press.avast.com/third-party-browser- extensions-from-instagram-facebook-vimeo-and-others-infected-with-malware.
