Provide Detailed Reports

When reporting a vulnerability, commit to providing clear and comprehensive details to help the organization reproduce and validate your findings. Include step-by-step instructions, proof-of-concept code if applicable, and any other relevant information that can assist the organization's security team in understanding and verifying the issue.

Be responsive to any requests for clarification, additional information, or coordination during the vulnerability verification process. Maintain open and respectful communication throughout the entire process, understanding that both parties are working together to improve security.

Always adhere to responsible disclosure practices. When you discover a vulnerability, avoid exploiting it for malicious purposes or sharing it with unauthorized parties. Instead, immediately report the vulnerability to the program organizers following the reporting process outlined in the program guidelines. This allows the organization to address the issue before potential harm can occur.


Safe Harbor

They are assured Legal Protection; by complying with all program terms, they're granted a legal safe harbor, ensuring they won't face lawsuits or legal actions for their reported findings. Participants also commit to Responsible Disclosure, providing ample time to address and rectify vulnerabilities and doesn't disclose any findings publically what so ever. Testing should be confined only to systems they have explicit authorization to assess. Furthermore, during the assessment, data access should be minimized, focusing only on what's necessary to validate a vulnerability, and retaining no user data beyond what is absolutely required.
