The tweet is asking about strategies to bypass a Web Application Firewall (WAF) when generic payloads are blocked, and how to create new payloads. It does not include a specific payload or vendor. In simple terms, when a usual attack payload is blocked by a WAF, the attacker tries to create new variations of the payload that can evade detection. This involves understanding how the WAF filters traffic, crafting payloads that are syntactically different but behave similarly, and testing them to see if they bypass the WAF. Techniques may include encoding, case manipulation, adding benign characters, or using alternative syntax. It's a trial-and-error process that requires knowledge of the WAF's rules and the vulnerability being targeted. This tweet highlights the challenge of bypassing WAFs and the need for creativity in payload crafting.
