Security of user data and communication is of utmost importance to In pursuit of the best possible security for our service, we welcome responsible disclosure of any vulnerability you find in Principles of responsible disclosure include, but are not limited to:

  • Accessing or exposing only customer data that is your own.
  • Avoiding scanning techniques that are likely to cause degradation of service to other customers (e.g. by overloading the site).
  • Keeping within the guidelines of our Terms of Service.
  • Keeping details of vulnerabilities secret until Fraudnet has been notified and had a reasonable amount of time to fix the vulnerability.
  • In order to be eligible for a bounty, your submission must be accepted as valid by Fraudnet. We use the following guidelines to determine the validity of requests and the reward compensation offered.

Our engineers must be able to reproduce the security flaw from your report. Reports that are too vague or unclear are not eligible for a reward. Reports that include clearly written explanations and working code are more likely to garner rewards.

More severe bugs will be met with greater rewards. We are most interested in vulnerabilities with and Other subdomains of Fraudnet are generally not eligible for rewards unless the reported vulnerability somehow affects or Fraudnet customer data.
