reCAPTCHA
Google reCAPTCHA is the most widely deployed CAPTCHA service, used to block automated abuse on forms, logins and signups. ScanMalware detects it from the reCAPTCHA API script and challenge iframe.
Its presence indicates anti-automation protection. Phishing kits also embed reCAPTCHA to look legitimate and to slow down automated analysis, so it should always be read alongside the full scan.

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