In this microblog, we'll keep you updated on the latest changes/additions to our bug bounty progrram. For a detailed scope, please see the bottom of our policy page.
At Ninja Kiwi, we are excited to engage with the security community to help us keep our users safe and our services secure. Our infrastructure team will review all reports submitted to us and will act on each accordingly.
Before submitting an issue, please take some time to read over the policy rules below.
Ninja Kiwi will make a best effort to meet the following response targets for hackers participating in our program:
| Type of Response | SLA in business days |
| ------------- | ------------- |
| First Response | 2 days |
| Time to Triage | 2 days |
| Time to Bounty | 5 days |
| Time to Resolution | depends on severity and complexity |
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 (e.g. phishing, vishing, smishing) is prohibited.
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.
This program covers the Ninja Kiwi domains outlined in the “In Scope” section below.
Our game clients are not in-scope and issues related to our game clients will not be eligible for any rewards. While our mobile/desktop game clients are not part of the program scope, they are the primary user agents for our api.ninjakiwi.com domain, which is an in-scope asset.
==Please note that ninjakiwi.com is explicitly out-of-scope and should not be confused with ninja.kiwi, which is an in-scope asset.==
Our APIs at api.ninjakiwi.com and analytics.ninjakiwi.comcom are key targets for this program and will be eligible to receive up to the maximum amount of the Critical vulnerability bounty range. Critical vulnerabilities found in all other in-scope assets will be capped at the lower end of the bounty range.
We are also interested in the following issues for our multiplayer relay servers:
If one is able to create a request that leads to an RCE on the servers or be able to extract data from the servers.
If one is able to crash the server process without resorting to DOS or large traffic volumes.
For the domain api.ninjakiwi.com, you can sign up for a free account from inside any of our recent games. Most of these games are free to play and are available on mobile and PC.
Google Play - https://play.google.com/store/apps/dev?id=7266924558817293669
Apple iOS - https://apps.apple.com/us/developer/ninja-kiwi/id386241773
Steam - https://store.steampowered.com/developer/ninjakiwigames
We generally do not enable certificate pinning; this means real world usage for our APIs can be seen by intercepting traffic from our game clients.

Any activities conducted in a manner consistent with this policy will be considered authorized conduct and we will not initiate legal action against you. If legal action is initiated by a third party against you in connection with activities conducted under this policy, we will take steps to make it known that your actions were conducted in compliance with this policy.
