This tweet talks about a new method called #KNOXSS, developed by @BRuteLogic, which uses advanced HTML injection (HTMLi) vectors and JavaScript injection (JSi) payloads to evade security filters and Web Application Firewalls (WAFs). The technology aims to help bypass defenses that normally block Cross-Site Scripting (XSS) attacks by using clever payloads that avoid detection. The researchers claim this innovation raises the level of XSS exploitation by making it harder for WAFs to detect and block malicious scripts. They also share a link to try out this tool, suggesting it is publicly accessible for testing and use.
