Leaflet
Leaflet is a popular lightweight open-source JavaScript library for interactive maps. ScanMalware detects it from its CSS and JS asset URLs and map-container markup.
It is a self-contained mapping library with little direct security weight, but its version and hosting source are still part of a site’s third-party code inventory.

How ScanMalware detects Leaflet
Leaflet 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 Leaflet is present, but how it is being used. Open the full search interface for Leaflet →
