Security is at the heart of mCaptcha. If you find any discrepancies in our software(see listing on our GitHub, services available at

Rules:

Before you start

  • Check the list of domains that are in scope for the Bug Bounty program and the list of targets for useful information for getting started.

  • Check the list of bugs that have been classified as ineligible.

  • Check our changelog(on our GitHub repositories) for recently launched features.

  • Never attempt non-technical attacks such as social engineering, phishing, or physical attacks against our employees, users, or infrastructure.

When in doubt, contact me(@realaravinth) at realaravinth@batense.net.

Performing your research

  • Do not impact other users with your testing, this includes testing vulnerabilities with CAPTCHA credentials and account credentials organizations you do not own. If you are attempting to find an authorization bypass, you must use accounts you own.

  • The following are never allowed for research. We may suspend your mCaptcha account for:

    • Performing distributed denial of service (DDoS) or other volumetric attacks. Sure, we are a DDos protection company, but with sufficient resources and motivation, it is possible to take us down. For this reason, we request you to not hammer us.

    • Spamming content Large-scale vulnerability scanners, scrapers, or automated tools which produce excessive amounts of traffic.

      Note: We do allow the use of automated tools so long as they do not produce excessive amounts of traffic. For example, running one nmap scan against one host is allowed, but sending 65,000 requests in two minutes using Burp Suite Intruder is excessive.

  • Researching denial-of-service attacks is allowed only if you follow these rules:

    • There are no limits for researching denial of service vulnerabilities against your own instance of mCaptcha server.

      We strongly recommend/prefer this method for researching denial of service issues.

    • If you choose to test on mCaptcha proper (i.e. https://mcaptcha.org or https://mcaptcha.io):

      • Research must be performed using credentials you own.
      • Stop immediately if you believe you have affected the availability of our services. Don’t worry about demonstrating the full impact of your vulnerability, our team will be able to determine the impact.

Handling personally identifiable information (PII)

  • Personally identifying information (PII) includes:

    • legal and/or full names
    • names or usernames combined with other identifiers like phone numbers or email addresses
    • health or financial information (including insurance information, social security numbers, etc.)
    • information about political or religious affiliations
    • information about race, ethnicity, sexual orientation, gender, or other identifying information that could be used for discriminatory purposes

  • Do not intentionally access others’ PII. If you suspect a service provides access to PII, limit queries to your own personal information.

  • Report the vulnerability immediately and do not attempt to access any other data. We will assess the scope and impact of the PII exposure.

  • Limit the amount of data returned from services. For SQL injection, for example, limit the number of rows returned

  • You must delete all your local, stored, or cached copies of data containing PII as soon as possible. We may ask you to sign a certificate of deletion and confidentiality agreement regarding the exact information you accessed. We may ask you for the usernames and IP addresses used during your testing to assess the impact of the vulnerability.

Reporting your vulnerability

  • Please include written instructions for reproducing the vulnerability.

  • When reporting vulnerabilities you must keep all information on in our email correspondence. Do not post information to video-sharing or pastebin sites.

  • For vulnerabilities involving personally identifiable information, please explain the kind of PII you believe is exposed and limit the amount of PII data included in your bug report. For textual information and screenshots, please only include redacted data in your bug report.

  • During the course of an investigation, it may take time to resolve the issue you have reported. We ask that you refrain from publicly disclosing details regarding an issue you’ve reported until the fix has been publicly made available.

Legal safe harbor:

We currently don't have any legal policies in place but you can rest assured that as long as your research adheres to the above rules, your security research and vulnerability disclosure activities are considered as "authorized".

A detailed policy based on this sentiment is in the works.

Scope:

mCaptcha runs a number of services. Only domains listed below are are eligible for security research. Any mCaptcha-owned domains not listed below are not in scope and are not covered by our legal safe harbor

mcaptcha.org

  • mcaptcha.org
  • demo.mcaptcha.org
  • demo2.mcaptcha.org
