This tweet talks about a new type of WAF (Web Application Firewall) bypass technique that uses machine learning, specifically reinforcement learning, to morph or transform payloads into forms that evade detection by firewalls. It describes the process as creating 'firewall ghosts,' meaning these payloads are like ghosts that pass through the firewall undetected. The approach uses a clean architecture designed for efficiency and effectiveness, showing 'no mercy' in bypassing WAF protections. The tweet is somewhat poetic and vague but highlights an advanced AI-driven method for penetrating web defenses, potentially affecting many types of vulnerabilities since it focuses on evasion technology rather than a specific attack vector.
