The ELZA is a scripting language aimed at automating requests on web pages. Scripts written in ELZA are capable of mimicking browser behavior almost perfectly, making it extremely difficult for remote servers to distinguish their activity from the activity generated by ordinary users and browsers. This gives those scripts the opportunity to act upon servers that will not respond to requests generated using netcat, rebol, telnet or similar tool. As a result, one can hijack heavily protected HTML forms, perform dictionary attacks on login forms, and do sophisticated CGI scanning.
