- Focus on high-impact bugs — Look for SQL injection, SSRF, and IDOR vulnerabilities first.
- Test authentication flows — Check for OAuth misconfigurations and CSRF in login/signup flows.
- Write clear reports — Include steps to reproduce, impact assessment, and suggested remediation. Use Burp Suite to capture evidence.
