The tweet suggests a manual bypass of a web application firewall (WAF) by using XOR techniques to evade detection. The bypass involves changing the sleep function to benchmark to avoid WAF blocking. The tweet hints at using manual techniques, tamper methods, and other tricks to successfully bypass the WAF. It highlights the ongoing challenge of finding vulnerabilities in WAFs and the creative methods used to bypass them. It would be beneficial to further investigate the specific techniques used and provide a detailed analysis in a blog post.
