This is a Phishing tool. Phishing is a type of hacking also called credential harvesting. It creates fake websites for victims to login which saves their login info which includes IP, User-Agent, Username and Password to a file in the computer running Blackeye. This tool has been there for Linux and even Android via Termux. I converted it to Windows.
Uhm....I downloaded the file but I can't open it as it's recognized as a virus by my pc.
