What is this?
XSStrike is a Cross Site Scripting (XSS) detection suite built around four hand-written parsers, an intelligent payload generator, a fuzzing engine, and a fast crawler. Instead of just firing generic payloads like most scanners, it analyzes the live response and crafts payloads guaranteed to work through context analysis.

Penetration testers and security researchers who need to actively probe web apps for reflected and DOM-based XSS, including bruteforcing payloads and discovering hidden parameters.What are Photon, Zetanize and Arjun used for?They are companion projects by the same author that power XSStrike's crawling (Photon), payload generation (Zetanize), and hidden parameter discovery (Arjun) features.
They are companion projects by the same author that power XSStrike's crawling (Photon), payload generation (Zetanize), and hidden parameter discovery (Arjun) features.What does WAF detection and evasion mean here?XSStrike fingerprints the target's web application firewall using signatures adapted from sqlmap, then tailors its payloads to try to slip past that specific WAF.
XSStrike fingerprints the target's web application firewall using signatures adapted from sqlmap, then tailors its payloads to try to slip past that specific WAF.How does Blind XSS support work?It lets you inject payloads that only execute later in an admin panel or log viewer, so you need an external callback collector set up to catch the results when they fire.
