This blog documents a large-scale parasite SEO (search engine poisoning) campaign identified across dozens of domains hosted on Cloudflare Pages.
The campaign relies on a reused malicious HTML template that impersonates Amazon style product pages, injects gambling related SEO spam, and abuses canonical, Open Graph, and structured data fields to hijack the reputation of unrelated legitimate websites.
Notably, the template also embeds a legitimate Amazon sign-in URL, further reinforcing the illusion of authenticity and increasing the phishing risk surface.
No direct credential harvesting or malware delivery was observed. Nevertheless, the activity is malicious by intent, designed to manipulate search rankings and mislead both users and search engines.
One critical finding in the analyzed html(landing page) template is the presence of a real Amazon sign-in URL:
Although the link itself points to a legitimate Amazon domain, its inclusion serves several malicious purposes:
Attackers increasingly favor this platform because it offers free and frictionless deployment, allowing malicious infrastructure to be spun up with minimal effort or cost. The ability to rapidly propagate and clone sites enables large-scale campaigns using identical templates across numerous URLs. Built-in HTTPS support lends a false sense of legitimacy to victims while reducing setup overhead for attackers. Finally, takedown at scale is challenging without direct provider intervention, making the infrastructure resilient and attractive for sustained phishing and social-engineering operations.
One of the most critical behaviors in this campaign is the deliberate misuse of trusted third-party websites via metadata fields:
In each deployment, these fields are set to different legitimate, unrelated websites, including:
Search engines treat canonical and structured data fields as strong trust signals. By embedding legitimate URLs, attackers attempt to:
This strongly confirms the presence of centralized template generation, with a single source producing identical page structures across multiple deployments. The consistent reuse further indicates automated deployment mechanisms, enabling rapid and large-scale rollout of these pages. Together, these patterns point to clear campaign level coordination, rather than isolated or opportunistic activity.
Hidden link farms are a strong indicator of malicious SEO activity, designed to manipulate backlink metrics without user visibility.

This campaign represents a coordinated parasite SEO operation that combines brand impersonation, reputation hijacking, and infrastructure abuse.
While no direct credential theft was observed, the inclusion of a legitimate Amazon sign-in link significantly increases the phishing risk potential, indicating a design that is deceptive by intent and easily extensible into active scams.
