Mixin Limited looks forward to working with the security community to find
security vulnerabilities in our core product - the Mixin Network mainnet code.
In order to empower the hacker community and facilitate testing, we have
created a public testnet for your use. The RPC nodes and claiming of test
token method are all detailed in the guide here:
Mixin Limited will make a best effort to meet the following response targets
for hackers participating in our program:
- Time to first response (from report submit) - 2 business days
- Time to triage (from report submit) - 2 business days
- Time to bounty (from triage) - 5 business days
We’ll try to keep you informed about our progress throughout the process.
- As this is a private program, please do not discuss this program or any vulnerabilities (even resolved ones) outside of the program without express consent from the organization.
- Follow HackerOne's disclosure guidelines __.
- Please provide detailed reports with reproducible steps. If the report is not detailed enough to reproduce the issue, the issue will not be eligible for a reward.
- Submit one vulnerability per-report, unless you need to chain vulnerabilities to provide impact.
- When duplicates occur, we only award the first report that was received (provided that it can be fully reproduced).
- Multiple vulnerabilities caused by one underlying issue will be awarded one bounty.
- Social engineering of Mixin Network Project staff or contractors (e.g. phishing, vishing, smishing) is prohibited.
- Any physical or electronic attempts against Mixin Network community property and/or data centers
- Make a good faith effort to avoid privacy violations, destruction of data, and interruption or degradation of our service. Only interact with accounts you own or with the explicit permission of the account holder.
Out of scope vulnerabilities
When reporting vulnerabilities, please consider (1) attack scenario /
exploitability, and (2) security impact of the bug. The following issues are
considered out of scope:
- Clickjacking on pages with no sensitive actions
- Cross-Site Request Forgery (CSRF) on unauthenticated forms or forms with no sensitive actions
- Attacks requiring MITM or physical access to a user's device.
- Previously known vulnerable libraries without a working Proof of Concept.
- Comma Separated Values (CSV) injection without demonstrating a vulnerability.
- Missing best practices in SSL/TLS configuration.
- Any activity that could lead to the disruption of our service (DoS).
- Content spoofing and text injection issues without showing an attack vector/without being able to modify HTML/CSS
- Rate limiting or bruteforce issues on non-authentication endpoints
- Missing best practices in Content Security Policy.
- Missing HttpOnly or Secure flags on cookies
- Missing email best practices (Invalid, incomplete or missing SPF/DKIM/DMARC records, etc.)
- Vulnerabilities only affecting users of outdated or unpatched browsers [Less than 2 stable versions behind the latest released stable version]
- Software version disclosure / Banner identification issues / Descriptive error messages or headers (e.g. stack traces, application or server errors).
- Public Zero-day vulnerabilities that have had an official patch for less than 1 month will be awarded on a case by case basis.
- Open redirect - unless an additional security impact can be demonstrated
- Issues that require unlikely user interaction
- Attacks which require more than f+1 nodes of the network to execute are out of policy scope. BFT __
