About this tag
The GhostRedirector campaign, disclosed by ESET Research, has compromised at least 65 Windows IIS servers to create a hidden SEO fraud network. Attackers install a native backdoor and an in-process IIS module that selectively redirects search engine crawlers to third-party gambling sites, while normal visitors see legitimate content. This technique, known as doorway pages, is used to manipulate search rankings without alerting site owners or users. The campaign was active from December 2024 to April 2025, targeting internet-facing Windows servers across multiple regions and sectors. The backdoor provides persistent remote access, enabling long-term control and fraud operations.
