This tweet talks about #KNOXSS, which is a tool that provides several cross-site scripting (XSS) bypass techniques specifically designed for various major Web Application Firewall (WAF) vendors. The tweet encourages security professionals and enthusiasts to try out these bypass methods. KNOXSS is built for professionals who need advanced bypasses for testing the effectiveness of WAFs against XSS attacks. It likely contains detailed payloads and techniques tailored to evade detection and blocking by popular WAFs, helping security testers identify vulnerabilities that these defenses might miss. Unfortunately, the tweet itself does not provide specific payloads or detailed technical information but highlights KNOXSS as a valuable resource for bypassing WAFs in the context of XSS vulnerabilities.
