Abstract
Systems and computer program products implement methods for detecting a man-in-the-middle (MITM) during HTTPS communications. The methods include establishing a TCP connection for the retrieval of a web page from a domain name using an alternate IP address that is different from the IP address of the target domain where receipt of the target web page in response to a HTTP GET message indicates that a MITM is present, using a domain name as the SNI in a TLS connection and an alternate domain name in a HTTP GET message where receipt of a target web page of the alternate domain name indicates that a MITM is present, and generating an alternate domain name using a domain generation algorithm and using the generated alternate domain name as the SNI in the TLS message where receipt of a certificate for the generated alternate domain name indicates that a MITM is present.
