About this tag
The seothreat tag on WindowsForum.com covers a specific type of cyberattack where threat actors compromise Windows servers to manipulate search engine rankings. The primary example is the GhostRedirector campaign, uncovered by ESET Research in June 2025, which infected at least 65 Windows servers across multiple countries. Attackers deployed a C++ backdoor called Rungan and a native IIS module named Gamshen to perform SEO fraud, serving altered content exclusively to search engine crawlers while showing normal content to human visitors. This technique, known as cloaking, is used to boost fraudulent websites in search results. Discussions under this tag focus on the technical details of such attacks, including server compromise methods, IIS module deployment, and detection strategies for enterprise IT security teams.
