Bootstrap

Bootstrap is a popular front-end CSS and JavaScript framework used to build responsive layouts quickly. It is identified from its characteristic class names, CSS and JS asset URLs, and bundled component markup.

Bootstrap is purely presentational and carries little direct security weight, but its ubiquity in website kits — including phishing templates — means its specific version and CDN source are still worth noting when fingerprinting a page.

How ScanMalware detects Bootstrap

Bootstrap 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 Bootstrap is present, but how it is being used.

Frequently asked questions about Bootstrap

Does using Bootstrap mean a website is unsafe?
No. Bootstrap is a stack component, not a verdict. ScanMalware scores the whole page — its scripts, redirects, certificates, threat-intelligence matches and behaviour — so a site using Bootstrap can be perfectly safe or actively malicious.
How many sites using Bootstrap has ScanMalware scanned?
Bootstrap has been detected in 21,769 public scans on ScanMalware.com. Each scan is a real headless-browser visit, and the figure updates as new URLs are submitted.
What technologies are commonly used with Bootstrap?
Across scanned sites, Bootstrap is most often seen alongside jQuery, JQuery and Open-Graph-Protocol. The full co-occurrence breakdown is listed on this page.
