Vulnerability Disclosure Policy

Ultrareach Internet Corp. is committed to maintaining the security of our systems and protecting sensitive information from unauthorized disclosure.

This policy describes what systems and types of security research are covered under this policy, how to send us vulnerability reports, and how long we ask security researchers to wait before publicly disclosing vulnerabilities.

We encourage security researchers to contact us to report potential vulnerabilities identified in Ultrasurf systems. For reports submitted in compliance with this policy, Ultrareach will acknowledge receipt within three business days, endeavor to timely validate submissions, implement corrective actions if appropriate, and inform researchers of the disposition of reported vulnerabilities.

If you make a good faith effort to comply with this policy during your security research, we will consider your research to be authorized, we will work with you to understand and resolve the issue quickly, and we will not recommend or pursue legal action related to your research.

Test Methods

Security researchers must not:

  • Test any system other than the systems set forth in the “Scope” section below,
  • disclose vulnerability information except as set forth in the “Reporting a Vulnerability” and “Disclosure” sections below,
  • engage in physical testing of facilities or resources, engage in social engineering,
  • send unsolicited electronic mail to Ultrasurf users, including “phishing” messages,
  • execute or attempt to execute “Denial of Service” or “Resource Exhaustion” attacks,
  • introduce malicious software,
  • test in a manner which could degrade the operation of Ultrasurf systems; or intentionally impair, disrupt, or disable Ultrasurf systems,
  • test third-party applications, websites, or services that integrate with or link to or from Ultrasurf systems,
  • delete, alter, share, retain, or destroy Ultrasurf data, or render Ultrasurf data inaccessible, or,
  • use an exploit to exfiltrate data, establish command line access, establish a persistent presence on Ultrasurf systems, or “pivot” to other Ultrasurf systems.

Security researchers may:

  • View or store Ultrasurf nonpublic data only to the extent necessary to document the presence of a potential vulnerability. Security researchers must:
  • cease testing and notify us immediately upon discovery of a vulnerability,
  • cease testing and notify us immediately upon discovery of an exposure of nonpublic data, and,
  • purge any stored Ultrasurf nonpublic data upon reporting a vulnerability.


The following systems / services are in scope:

  • Ultrasurf windows client
  • Ultrasurf Android VPN client
  • Ultrasurf servers and networks

Any services not explicitly listed above are excluded from scope.

Reporting a Vulnerability

Reports are accepted via electronic mail at info9 @ Acceptable message formats are plain text, rich text, and HTML.

Reports should provide a detailed technical description of the steps required to reproduce the vulnerability, including a description of any tools needed to identify or exploit the vulnerability. Images, e.g., screen captures, and other documents may be attached to reports. It is helpful to give attachments illustrative names. Reports may include proof-of-concept code that demonstrates exploitation of the vulnerability. We request that any scripts or exploit code be embedded into non-executable file types. We can process all common file types, and also file archives including zip, 7zip, and gzip.

Researchers may submit reports anonymously. Or, researchers may provide contact information, and any preferred methods or times of day to communicate, as they see fit. We may contact researchers to clarify reported vulnerability information or other technical interchange.

Ultrareach prefers that vulnerability report messages be encrypted. We utilize opportunistic Transport Layer Security (TLS) for both incoming and outgoing electronic mail. Reporters may opt to use OpenPGP standard cryptography for message encryption. The Ultrareach PGP public key may be downloaded in ASCII Armor Format at 0xBF3FEFD90C5BC427.asc. PGP Key Properties are as follows:

Key ID: 0xBF3FEFD90C5BC427
Key Fingerprint: 018A E8C8 CBDB B9D7 2EF7 E822 8AE0 D0A6 BDC8 29CF

By submitting a report to the Ultrasurf, researchers warrant that the report and any attachments do not violate the intellectual property rights of any third party and the submitter grants the Ultrasurf a non-exclusive, royalty-free, world-wide, perpetual license to use, reproduce, create derivative works, and publish the report and any attachments.


The Ultrasurf is committed to timely correction of vulnerabilities. However, we recognize that public disclosure of a vulnerability in absence of a readily-available corrective action likely increases versus decreases risk. Accordingly, we require that you refrain from sharing information about discovered vulnerabilities for 90 calendar days after you have received our acknowledgement of receipt of your report. If you believe others should be informed of the vulnerability prior to our implementation of corrective actions, we require that you coordinate in advance with us.


Questions regarding this policy may be sent to info9 @ The Ultrasurf encourages security researchers to contact us for clarification on any element of this policy. Please contact us prior to conducting research if you are unsure if a specific test method is inconsistent with or unaddressed by this policy. We also invite security researchers to contact us with suggestions for improving this policy.
