OpenSearch
This signal marks an OpenSearch description document, linked from a page to let browsers add the site as a search engine. ScanMalware detects it from the search-link reference in the page head.
It is a minor discovery feature with little security weight, recorded as part of a complete page fingerprint.

How ScanMalware detects OpenSearch
OpenSearch is detected by analysing the response headers, HTML markup, JavaScript runtime and asset URLs captured when ScanMalware loads the site in a real headless browser.
From any scan you can pivot into related signals — JARM TLS fingerprints, ASN ownership and BGP routing, certificate history, JavaScript analysis and the overall security verdict — to understand not just that OpenSearch is present, but how it is being used.

- OpenSearch has been detected in 5,863 public scans on ScanMalware.com. Each scan is a real headless-browser visit, and the figure updates as new URLs are submitted.
