Responsible Disclosure Program

VNG is devoted to preserving the security of its clients by preventing unauthorized disclosure of personal information. This policy provides security researchers with clear parameters for performing vulnerability discovery operations and communicates our preferences in submitting found vulnerabilities.

This policy explains which systems and types of research are covered, how to send us vulnerability reports, and how long security researchers must wait before revealing vulnerabilities publicly.

As outlined in this policy, we want security researchers to feel comfortable reporting vulnerabilities they have uncovered so that we can address them and keep our users safe. This policy reflects our beliefs and demonstrates our feeling of duty toward security researchers who share their knowledge with us in good faith.


If you make a good faith effort to comply with this policy throughout your security research, we will consider it is authorized and VNG will not pursue legal action with your research.

Systems in Scope

This policy applies to any digital assets owned, operated, or maintained by VNG.

Out of Scope

Assets or other equipment not owned by parties participating in this policy.

Vulnerabilities discovered or suspected in out-of-scope systems should be reported to the appropriate vendor or applicable authority.

Our Commitments

When working with us, according to this policy, you can expect us to:

  • Respond to your report promptly, and work with you to understand and validate your report;

  • Strive to keep you informed about the progress of a vulnerability as it is processed;

  • Work to remediate discovered vulnerabilities in a timely manner, within our operational constraints; and

  • Extend Safe Harbor for your vulnerability research that is related to this policy.

Coordinated Disclosure

In participating in our vulnerability disclosure program in good faith, we ask that you:

  • Report any vulnerability you have discovered promptly;

  • Avoid violating the privacy of others, disrupting our systems, destroying data, and/or harming user experience;

  • Use only the Official Channels to discuss vulnerability information with us;

  • Provide us a reasonable amount of time (at least 90 days from the initial report) to resolve the issue before you disclose it publicly;

  • Perform testing only on in-scope systems, and respect systems and activities which are out-of-scope;

  • If a vulnerability provides unintended access to data: Limit the amount of data you access to the minimum required for effectively demonstrating a Proof of Concept; and cease testing and submit a report immediately if you encounter any user data during testing, such as Personally Identifiable Information (PII), Personal Healthcare Information (PHI), credit card data, or proprietary information;

  • You should only interact with test accounts you own or with explicit permission from the account holder; and

  • Do not engage in extortion.

Official Channel

Please report security issues via, providing all relevant information. The more details you provide, the easier it will be for us to triage and fix the issue.

Safe Harbor

When conducting vulnerability research, according to this policy, we consider this research conducted under this policy to be:

  • Authorized concerning under Vietnam Cybersecurity Law, and we will not initiate or support legal action against you for accidental, good-faith violations of this policy

  • Authorized concerning any relevant anti-circumvention laws, and we will not bring a claim against you for circumvention of technology controls;

  • Exempt from restrictions in our Terms of Service (TOS) and/or Acceptable Usage Policy (AUP) that would interfere with conducting security research, and we waive those restrictions on a limited basis; and

  • Lawful, helpful to the overall security of the Internet, and conducted in good faith.

You are expected, as always, to comply with all applicable laws. If legal action is initiated by a third party against you and you have complied with this policy, we will take steps to make it known that your actions were conducted in compliance with this policy.

If at any time you have concerns or are uncertain whether your security research is consistent with this policy, please submit a report through one of our Official Channels before going any further.

Note that the Safe Harbor applies only to legal claims under the control of the organization participating in this policy, and that the policy does not bind independent third parties.


Read our policy carefully before submitting a report.

Only VSRC should receive the report.
