XSStrike is a Cross Site Scripting detection suite equipped with four hand written parsers, an intelligent payload generator, a powerful fuzzing engine and an incredibly fast crawler.
Instead of injecting payloads and checking it works like all the other tools do, it analyses the response with multiple parsers and then crafts payloads that are guaranteed to work with context analysis integrated with a fuzzing engine. Here are some examples of the payloads generated by it:
}]};(confirm)()//\ <A%0aONMouseOvER%0d=%0d.find(confirm)>z </tiTlE/><a%0donpOintErentER%0d=%0d(prompt)``>z </SCRiPT/><DETAILs/+/onpoINTERenTEr%0a=%0aa=prompt,a()//
Apart from that, it has crawling, fuzzing, parameter discovery, WAF detection capabilities as well. It also scans for DOM XSS vulnerabilities.
