Reporting Security Issues
If you come across any issues or vulnerabilities in our systems, we would greatly appreciate your sharing this information with us as soon as possible. Major security flaws will be rewarded with a sum of bitcoins (bug bounty) or an honorable mention on our “wall of fame”. The reward amount will depend on the impact of the error, up to a maximum of 2 BTC. Rewards will only be given if you are the first to notify us of a security issue and if it results in a change in the code or configuration. It is imperative that vulnerabilities are not disclosed publicly or shared with third parties until adequate time has been given to resolve the issue. Below are some examples of security errors.

Some security errors are not eligible for a reward as they have a low impact on security. Examples of such security errors are listed below. Please do not report these flaws unless a combination of errors results in a security issue with a greater impact.

HTTP 404 and other non-HTTP 200 error codes Accessibility of public files and folders (like robots.txt) CSRF-issues on parts of the site accessible to anonymous visitors CSRF-issues without (critical) consequences for users Trace HTTP functions that may be active SSL attacks like BEAST, BREACH, Renegotiation Unused SSL Forward secrecy Anti-MIME-Sniffing header X-Content-Type-functions Missing HTTP security headers Presence of HTTPS Mixed Content Scripts / errors SPF Record settings Rules
