Malvertising

WHAT IS MALVERTISING?

Unlike ad fraud, which compromises the quality of web traffic through fake users and bots, malvertising compromises the safety and quality of digital ads—using them to spread malware or phishing campaigns. While ad fraud mainly affects advertisers, malvertising targets publishers and users with tactics like forced redirects that trick users into installing malware onto their computers. That’s not only bad for a user’s experience—it’s bad for business, too.
