HTTPS is built on top of the TLS/SSL cryptographic protocols and is designed to prevent MITM (man-in-the-middle) attacks, before the HTTP request is sent to the server it is encrypted using TLS/SSL, this means that any malware intercepting socket functions would receive encrypted data it could not read.
