The tweet expresses a common sentiment among security researchers and hackers about Web Application Firewalls (WAFs). The user @sudo_a7med humorously indicates that facing WAF protections frequently leads to challenges but also serves as a learning experience. The tweet underlines the continuous effort to understand and bypass WAFs. Since no specific payload or vendor is mentioned, we can only conclude that WAF bypassing is an ongoing learning process that requires practice and persistence. It highlights the cat-and-mouse game between attackers and WAF developers, where attackers keep trying new methods to bypass protections while WAFs improve their defenses.
