Search Engine Phishing
Phishing
Search engine phishing, also known as SEO poisoning, involves manipulating search engine results to place malicious websites in prominent positions for targeted search queries. Attackers use black-hat SEO techniques, paid search advertisements, and compromised high-authority websites to ensure that their phishing pages appear above or alongside legitimate results when users search for specific brands, services, or products.
This attack vector is particularly dangerous because users inherently trust search engine results, assuming that top-ranked pages have been vetted for legitimacy. Attackers target commercial intent keywords such as brand names followed by "login," "support," "download," or "customer service," catching users at the exact moment they are looking to interact with the impersonated brand. Paid search ads are especially effective because they appear above organic results and carry an implicit endorsement from the search engine.
The sophistication of search engine phishing has grown to include cloaking techniques where the malicious page presents different content to search engine crawlers than to human visitors. This allows phishing pages to pass automated content reviews while serving malicious content to actual users. Some campaigns use chains of redirects through legitimate domains to obscure the final destination and evade URL-based detection.

Key Statistics
