Program Rules

Testing Policy and Responsible Disclosure

Please adhere to the following rules while performing research on this program:

  • Denial of service (DoS) attacks on Okto applications, servers, networks or infrastructure are strictly forbidden.
  • Avoid tests that could cause degradation or interruption of our services.
  • Do not use automated scanners or tools that generate large amount of network traffic.
  • Do not leak, manipulate, or destroy any user data or files in any of our applications/servers.
  • Do not copy any files from our applications/servers and disclose them.
  • No vulnerability disclosure, full, partial or otherwise, is allowed.

Important precautions and limitations

As a complement to the Program’s rules and testing policy :

  • DO NOT alter compromised accounts by creating, deleting, removing or modifying any data
  • DO NOT use compromised accounts to search for post-auth vulnerabilities (they won’t be eligible anyway)
  • DO NOT include Personally Identifiable Information (PII) in your report and please REDACT/OBFUSCATE the PII that is part of your PoC (screenshot, server response, JSON file, etc.) as much as possible.
  • In case of exposed credentials or secrets, limit yourself to verifying the credentials validity
  • In case of sensitive information leak, DO NOT extract/copy every document or data that is exposed and limit yourself to describe and list what is exposed.

Reward Eligibility

We are happy to thank everyone who submits valid reports which help us improve the security of Okto, however only those that meet the following eligibility requirements may receive a monetary reward:

  • You must be the first reporter of a vulnerability.
  • The vulnerability must be a qualifying vulnerability (see below).
  • The report must contain the following elements:
    • Clear textual description of the vulnerability, how it can be exploited, the security impact it has on the application, its users and Okto, and remediation advice on fixing the vulnerability
    • Proof of exploitation: screenshots demonstrating the exploit was performed, and showing the final impact
    • Provide complete steps with the necessary information to reproduce the exploit, including (if necessary) code snippets, payloads, commands etc
  • You must not break any of the testing policy rules listed above
  • You must not be a former or current employee of Okto or one of its contractors.

Reward amounts are based on:

  • Reward grid of the report's scope
