The tweet promotes the eWPTX certification which is a fully hands-on training program for web application security. It emphasizes practical skills rather than just theory. The program includes 45 hands-on labs, over 76 hours of content, and an 18-hour practical exam. The topics covered in the training include APIs, advanced injection techniques, authentication attacks, and WAF (Web Application Firewall) bypass. Successfully passing the exam signifies that a candidate can handle real-world web application attacks. However, the tweet does not provide a specific WAF bypass payload or mention a particular vendor, so no technical details about a specific bypass can be analyzed or explained.
