Coinify responsible disclosure policy

  • Updated

At Coinify, we consider the security of our systems a top priority. But no matter how much effort we put into system security, there can still be vulnerabilities present.

If you discover a vulnerability, we would like to know about it so we can take steps to address it as quickly as possible. We would like to ask you to help us better protect our clients and our systems.

It will be at Coinify’s discretion whether we deem the vulnerability to be of importance. We are aware of some vulnerabilities that we consider to be of lesser importance and have, thus, chosen not to correct them.

Please do the following:

  • E-mail your findings to security@coinify.com. If your findings contain sensitive information, encrypt your findings using our PGP key to prevent this critical information from falling into the wrong hands.
  • Do not take advantage of the vulnerability or problem you have discovered, for example, by downloading more data than necessary to demonstrate the vulnerability or deleting or modifying other people’s data.
  • Do not reveal the problem to others until it has been resolved.
  • Do not use attacks on physical security, social engineering, distributed denial of service, spam or applications of third parties.
  • Do provide sufficient information to reproduce the problem, so we will be able to resolve it as quickly as possible. Usually, the IP address or the URL of the affected system and a description of the vulnerability will be sufficient, but complex vulnerabilities may require further explanation.

What we promise:

  • We will respond to your report within 10 business days with our evaluation of the report and an expected resolution date.
  • If you have followed the instructions above, we will not take any legal action against you in regard to the report.
  • We will handle your report with strict confidentiality and not pass on your personal details to third parties without your permission.
  • We will keep you informed of the progress towards resolving the problem.
  • In the public information concerning the problem reported, we will give your name as the discoverer of the problem (unless you desire otherwise), and
  • As a token of our gratitude for your assistance, we offer a reward for every report of a security problem that is not yet known to us.
  • The amount of the reward will be determined based on the severity of the leak and the quality of the report. The minimum reward will be a €50 gift certificate.

In Scope

The program scope covers all software vulnerabilities in services provided by Coinify. Any design or implementation issue that is reproducible and substantially affects the security of Coinify users is likely to be in scope for the program. Common examples include:

  • Injections
  • Cross-Site Scripting (XSS)
  • Cross-Site Request Forgery (CSRF)
  • Remote Code Execution (RCE)
  • Shell Upload vulnerabilities (only upload basic backend script that just prints some string; preferably try printing the hostname of the server and stop there!)
  • Authentication/Authorization flaws
  • Domain take-over vulnerabilities
  • You are able to take-over other Coinify user accounts (while testing; use your own test account to validate)
  • Any vulnerability that can affect the Coinify brand, user data and financial transactions

When in doubt, consider what an attack scenario would look like. How would the attacker benefit? What would be the consequence to the victim?

Specific domains hosting Coinify services are provided below:

  • *.coinify.com (All assets on coinify.com and subdomains, excepting services provided by third parties, see below.)
  • mycoinify.com

If you feel that a particular asset or activity not mentioned here should be covered by this scope, please submit a report along with a brief description of why you believe that the asset should be covered by this scope.
