Tips for Hacking DuckDuckGo

1. Read the policy — Understand what's in scope, out of scope, and any specific testing restrictions before you start.
2. Enumerate the attack surface — Use subdomain enumeration and directory bruteforcing to map all accessible endpoints.
3. Focus on high-impact bugs — Look for SQL injection, SSRF, and IDOR vulnerabilities first.
4. Test authentication flows — Check for OAuth misconfigurations and CSRF in login/signup flows.
5. Write clear reports — Include steps to reproduce, impact assessment, and suggested remediation. Use Burp Suite to capture evidence.
