Microsoft ASP.NET
ASP.NET is Microsoft’s server-side web-application framework, common across enterprise and government sites. ScanMalware detects it from X-AspNet-Version and X-Powered-By headers, ASP.NET_SessionId cookies and .aspx URLs.
Exposed framework version headers and legacy ASP.NET features (such as ViewState handling) have a history of security issues, so the disclosed details are worth checking when assessing a site.

How ScanMalware detects Microsoft ASP.NET
Microsoft ASP.NET 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 Microsoft ASP.NET is present, but how it is being used.
