Brand Impersonation Detection
The process of identifying web pages, emails, or domains that visually or structurally mimic legitimate brands to deceive users.
Overview
Brand impersonation is the core technique behind most phishing attacks. Attackers clone the visual identity of trusted brands - logos, color schemes, typography, layout, and login flows - to create convincing fake pages. Traditional detection relies on keyword matching or domain reputation, both of which miss sophisticated clones hosted on legitimate infrastructure. Modern brand impersonation detection uses computer vision to analyze the rendered page, comparing visual fingerprints against known brand assets. This approach catches impersonation even when the domain appears legitimate, the SSL certificate is valid, and the HTML is obfuscated. It is especially critical for detecting executive impersonation, SSO page cloning, and internal portal spoofing.
