🧱 WAF Bypass Lab
A WAF (Web Application Firewall) blocks "obvious" payloads, but a blocklist filter can almost always be evaded. Each level gives you the WAF rules and a goal: write a payload that passes the filter and achieves the attack. It is a simulator, everything runs in your browser.
🏁 All 4 levels cleared!
