This tweet discusses modern Web Application Firewalls (WAFs) and their effectiveness against attacks. It mentions a new e-book that deeply examines how WAFs work, the protection mechanisms they enable against attacks, and the bypass techniques used by attackers. The tweet does not provide specific payloads or vendor names, but highlights the importance of understanding WAF defenses and how attackers try to circumvent them. The e-book seems like a valuable resource for learning about WAF technology, including both defensive tactics and bypass methods. Given the general nature of the tweet, it applies broadly to modern WAF products rather than a specific vendor or vulnerability type.
