    Researchers uncover 152 Chrome wallpaper extensions tied to adware and fake traffic

    Initial Disclosure

    Researchers uncovered 152 Google Chrome extensions posing as live-wallpaper new-tab add-ons and linked them to a financially motivated commercial adware and traffic-attribution-fraud affiliate operation. The cluster spans 38 Chrome Web Store publisher accounts and three brand backends, with 105,000 installs, and the listings' privacy policies admit logging IP addresses, ISP, click counts, and referrers while sharing that data with Google AdSense, DoubleClick, and third-party ad partners. Some extensions also use hard-coded install and uninstall URLs in js/bg.js to disguise self-opened tabs as organic Google traffic and to make uninstall activity look like genuine Google Search clicks.
