html-injection-testing

This document is an actionable offensive playbook for HTML injection, phishing overlays, credential exfiltration, and defacement. It contains precise payloads, automated testing scripts, and bypass techniques that materially lower the effort required to exploit vulnerable targets. While remediation guidance is present and accurate, the overall content poses a significant abuse risk if used outside authorized security testing. Mitigation: restrict distribution, require documented authorization for use, and ensure such content is stored/used only in approved security-testing contexts.
