Adware & Monopolizing Software
Threat Landscape & Operational Overview
Adware encompasses software designed to forcefully display unwanted advertisements, inject commercial banners into web browsing sessions, redirect search queries to affiliate marketing hubs, and track user browsing habits without meaningful consent. Often bundled with freeware installers or delivered via shady software download portals, adware degrades system performance, compromises user privacy, and creates vulnerable attack surfaces that can be exploited by higher-severity malvertising and dropper campaigns.
