WAF Bypass Techniques + Tools
Here are some powerful tools and methods to help you bypass Web Application Firewalls during bug hunting:
🔥 Tools:
- wafw00f — WAF fingerprinting tool
→ https://github.com/EnableSecurity/wafw00f
- bypass-firewalls-by-DNS-history — Discover origin IPs via old DNS records
→ https://github.com/vincentcox/bypass-firewalls-by-DNS-history
- CloudFail — Excellent for bypassing Cloudflare
→ https://github.com/m0rtem/CloudFail
🔥 Effective Bypass Techniques:
1. Origin IP Discovery — Use historical DNS records (Censys, etc.) to find the real server IP and connect directly.
2. Dev/Staging Subdomains — These often don’t have WAF protection.
3. Case Variations — Try
4. Comment Injection —
5. Multiple Encodings — URL → Double URL → Unicode, etc.
6. Parameter Pollution —
7. HTTP Method Swap — Change from GET → POST → PUT
8. Content-Type Swap — Switch between form-data, JSON, XML
9. HTTP/2 Cleartext — Some WAFs only inspect HTTP/1.1
Quick WAF Detection Command:
Save this for your next bug bounty hunt! 🔥

url/?f=etc/passwd ==> 403
encode etc/passwd as base64
url/?f=L2V0Yy9wYXNzd2Q= ==> 200
you can use this trick in SQL , SSTI , XSS , LFI , Etc...

🛡️ Bug Bounty Tip: Test IDOR + Web Cache Deception Together
When hunting IDORs, always check for web cache deception on the same endpoints:
1. As User A, access a sensitive resource like /api/invoices/123 (also try appending .css or
2. As User B, repeat the exact same URL with identical headers.
3. Only change the Cookie/Auth token.
If User B receives User A's 200 OK response from cache → you've likely found a critical vulnerability!
This combo can lead to account takeover-level impacts.

We’re building a serious international Red Teaming education initiative, and we’re looking for experienced Red Teamers to join the team.
The goal is not to create another course platform. We want to build practical, high-quality training based on real-world attack methodologies, adversary tradecraft, hands-on scenarios, and the mindset required to operate as a Red Teamer.
Our training will be developed and published in English for a global audience.
If you’re an experienced Red Teamer, penetration tester, or security practitioner and you’re interested in contributing your expertise and helping build something from the ground up, I’d be glad to connect and discuss the project.
If this sounds interesting, send me a message :
