Evilginx2 is a man-in-the-middle attack framework used to phishing login credentials along with collecting cookies login, which in turn allows 2FA protection to be bypassed.
That particular tool is the successor to Evilginx, released in 2017, which used a custom version of the nginx HTTP server to provide man-in-the-middle functionality and to act as a proxy between aletterbrowsing and a phished website.
This version is completely written in GO as a standalone application, which has its own HTTP and DNS server, making it extremely easy to set up and use.
You will find information about the installation and the use of the program here.
