Ad Fraud

Malvertising — Definition & Explanation

Malicious advertising — ads containing harmful code that can redirect users to dangerous sites, install malware, mine cryptocurrency, or steal personal data. Malvertising is one of the most serious ad quality threats publishers face.

How Malvertising Works

Malicious actors purchase display advertising and inject malicious JavaScript into ad creatives. When the ad renders, the code executes in the user's browser, potentially redirecting them or installing malware without user interaction.

Why Malvertising Matters for Publishers

A single malvertising incident can destroy publisher trust and result in blacklisting by premium demand partners. Stellor Media implements creative scanning and monitoring to protect publisher partner sites.
