hCaptcha
hCaptcha is a privacy-oriented CAPTCHA service used to block automated abuse on forms and logins. ScanMalware detects it from the hCaptcha widget script and challenge iframe.
Its presence indicates anti-automation protection. On credential-collecting pages a CAPTCHA can also be used by phishing kits to appear legitimate, so it should be read in context.

How ScanMalware detects hCaptcha
hCaptcha 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 hCaptcha is present, but how it is being used.
