arachni 0.3

Arachni is a feature-full, modular, high-performance Ruby framework aimed towards helping penetration testers and administrators evaluate the security of web applications. Arachni is smart, it trains itself by learning from the HTTP responses it receives during the audit process. Unlike other scanners, Arachni takes into account the dynamic nature of web applications and can detect changes caused while travelling through the paths of a web application's cyclomatic complexity. This way attack/input vectors that would otherwise be undetectable by non-humans are seamlessly handled by Arachni. Finally, Arachni yields great performance due to its asynchronous HTTP model (courtesy of Typhoeus). Thus, you'll only be limited by the responsiveness of the server under audit and your available bandwidth. Note: Despite the fact that Arachni is mostly targeted towards web application security, it can easily be used for general purpose scraping, data-mining, etc with the addition of custom modules.
