    • Nitro Security Vulnerability & Bug Bounty Policy

      Policy

      Nitro is proud to have required few historical Product Updates for security vulnerabilities. Keeping user information safe and secure is a top priority and a core company value for us at Nitro. We welcome the contribution of external security researchers and look forward to awarding them for their invaluable contribution to the security of all Nitro users.

      Rewards

      Nitro provides rewards for accepted vulnerability reports at its discretion. Our minimum reward is a $25 USD Amazon gift card. Reward amounts may vary depending upon the severity of the vulnerability reported and quality of the report. Keep in mind that this is not a contest or competition. We reserve the right to determine amount or even whether a reward should be granted.

      Applications in Scope

      Nitro Pro, Nitro Sign and Nitro Admin applications are eligible for the bounty program. In addition, any cloud-based partner platform applications are also eligible (eg Nitro File Actions). We may still reward anything with significant impact across our entire security posture, so we encourage you to report such vulnerabilities via this program.

      Security Vulnerability Reporting & Eligibility

      All Nitro security vulnerabilities should be reported via email to the Nitro Security Team at . To promote the discovery and reporting of vulnerabilities and increase user safety, we ask that you:

      • Share the security issue with us in detail, including the application name, version/build affected, concise steps to reproduce the vulnerability that are easily understood, information on the actual and potential impact of the vulnerability, and details of how it could be exploited;
      • Include a proof-of-concept file;
      • Please be respectful of our existing applications. Spamming forms through automated vulnerability scanners will not result in any bounty reward since those are explicitly out of scope;
      • Give us a reasonable time to respond to the issue before making any information about it public;
      • Do not access or modify our data or our users’ data, without explicit permission of the owner. Only interact with your own accounts or test accounts for security research purposes;
      • Contact us immediately if you do inadvertently encounter user data. Do not view, alter, save, store, transfer, or otherwise access the data, and immediately purge any local information upon reporting the vulnerability to Nitro;
      • Act in good faith to avoid privacy violations, destruction of data, and interruption or degradation of our services (including denial of service); and
      • Otherwise comply with all applicable laws.

      We only reward the first reporter of a vulnerability. Public disclosure of the vulnerability prior to resolution may cancel a pending reward. We reserve the right to disqualify individuals from the program for disrespectful or disruptive behavior.

      We will not negotiate in response to duress or threats (e.g., we will not negotiate the payout amount under threat of withholding the vulnerability or threat of releasing the vulnerability or any exposed data to the public).

      Security Vulnerability Process:

      (1) Nitro will acknowledge and assess any vulnerability reported according to the instructions above, typically within 7 days.

      (2) When a vulnerability is confirmed, Nitro will conduct risk analysis using the Common Vulnerability Scoring System (CVSS v3) and determine the most appropriate response for Nitro customers.

      • Critical Security Vulnerabilities: Issues within the software that, if not addressed, pose a high risk and probability of unauthorized access, alteration or destruction of information on a user's computer or connected computers. Nitro will resolve critical security vulnerabilities with a Product Update to the Current and Previous Release of Nitro Pro, and all cloud services, according to the .
      • Non-Critical Security Vulnerabilities: Issues within the software that, if not addressed, pose a low to moderate risk and probability of unauthorized access, alteration or destruction of information on a user's computer or connected computers. Nitro at its discretion, will resolve Non-Critical Security Vulnerabilities with a Product Update to the Current Release of Nitro Pro only, and all cloud services according to the .

      (3) Nitro will design, implement & test a fix for all Critical Security Vulnerabilities, and provide a Product Update to customers, typically within 90 days.

      (4) Nitro will publicly disclose all Critical Security Vulnerabilities, affected versions, and relevant details of Product Updates that address the issues, on this Nitro Security Updates page. Nitro does not publicly acknowledge individual security researchers for their submissions.

      Out-of-Scope Security Vulnerabilities

      The following issues are outside the scope of this policy & rewards program:

      • Attacks requiring physical access to a user's device.
      • Missing security headers which do not lead directly to a vulnerability.
      • Missing best practices (we require evidence of a security vulnerability).
      • Use of a known-vulnerable library (without evidence of exploitability).
      • Social engineering of Nitro employees or contractors.
      • Reports of insecure SSL/TLS ciphers (unless you have a working proof of concept, and not just a report from a scanner).
      • Content spoofing and pure text injection vulnerabilities (where you can only inject text or an image into a page). We will accept and resolve a spoofing vulnerability where attacker can inject image or rich text (HTML), but it is not eligible for a bounty.
      • Nitro services unless you are able to hit private IPs or Nitro servers.

      Consequences of Complying with This Policy

      We will not pursue civil action or initiate a complaint to law enforcement for accidental, good faith violations of this policy. We consider activities conducted consistent with this policy to constitute “authorized” conduct under the Computer Fraud and Abuse Act. To the extent your activities are inconsistent with certain restrictions in our Acceptable Use Policy, we waive those restrictions for the limited purpose of permitting security research under this policy. We will not bring a DMCA claim against you for circumventing the technological measures we have used to protect the applications in scope.

      If legal action is initiated by a third party against you and you have complied with Nitro’s Security Vulnerability & Bug Bounty Policy, Nitro will take steps to make it known that your actions were conducted in compliance with this policy.

      Please submit a report to us before engaging in conduct that may be inconsistent with or unaddressed by this policy.

      The Fine Print

      You are responsible for paying any taxes associated with rewards. We may modify the terms of this program or terminate this program at any time. We won’t apply any changes we make to these program terms retroactively. Reports from individuals who we are prohibited by law from paying are Ineligible for rewards. Nitro employees and their family members are not eligible for any rewards.

      In order to encourage the adoption of bug bounty programs and promote uniform security best practices across the industry, Nitro reserves no rights in this bug bounty policy and so you are free to copy and modify it for your own purposes.

    • Security Incident Update

      On September 30, 2020, Nitro became aware of an isolated security incident involving limited access to Nitro databases by an unauthorized third party.

      Upon learning about this incident, Nitro took immediate action to ensure the Nitro environment was secure and commenced an investigation with the support of leading cybersecurity and forensic experts. The investigation is now complete, and Nitro can provide further details:

      • The incident involved access to specific Nitro databases, which support certain online services and have been used primarily for the storage of information connected with Nitro’s free online products.
      • Nitro’s free online conversion service does not require users to create a Nitro account or to become a Nitro customer. Users are simply required to provide an email address to which converted files are delivered.
      • There was no impact to Nitro Pro or Nitro Analytics.
      • Exposed user data included user email addresses, full names, highly secure hashed and salted passwords, as well as document metadata in relation to the Nitro online services. A very small portion of the information included company names, titles, and IP addresses.
      • Passwords were not impacted for users who access our cloud services via Single Sign-On (SSO).
      • The investigation further identified limited activity by the unauthorized third party in a legacy cloud services location, impacting less than 0.0073% of stored data in this location. The activity suggests the unauthorized third party was specifically focused on obtaining data related to cryptocurrency.

      Upon learning of this incident, Nitro conducted a forced password reset for all users to further secure customer accounts. In addition to this, general guidance to maintain good cyber hygiene includes:

      • Changing online account passwords regularly, using a separate password for online banking, and using a password manager for remembering multiple passwords.
      • Never emailing passwords for online accounts and confirming if online accounts are secure by visiting .
      • Enabling multi-factor authentication for online accounts where possible and ensuring up-to-date anti-virus software is installed on any device used to access online accounts.

      Since the incident, the Nitro IT Security Team has been working closely with external cybersecurity experts to bolster the security of all systems, including enhanced logging, detection and alerting services in all regions, as well as increased data monitoring and re-evaluation of all protocols. The IT environment remains secure and Nitro has not seen any malicious activity since the incident.

      Nitro takes the safety and security of our customers’ data seriously, and we are here to support our customers in any way that may be helpful. We encourage anyone with questions to contact .
