Rules of engagement
Our promise to you
- We are happy to respond to any questions, please use the button in the right top corner to contact us
- We respect the safe harbour clause that you can find below
Your promise to us
- Provide detailed but to-the point reproduction steps
- Include a clear attack scenario. How will this affect us exactly?
- Remember: quality over quantity!
- Please do not discuss or post vulnerabilities without our consent (including PoC's on YouTube and Vimeo or any other service)
- Please do not use automatic scanners -be creative and do it yourself! We cannot accept any submissions found by using automatic scanners. Scanners also won't improve your skills, and can cause a high server load (we'd like to spend our time in thanking researchers rather than blocking their IP's 😉)
In scope
Sqills is pleased to announce our public bug bounty program! We've done our best to resolve most of our known issues and now would like to request your help to find the ones we may have missed! We are specifically looking for:
- vulnerabilties that lead to modification of content on the corporate website
- vulnerabilities that provide access to the management system or server that hosts the corporate website
- vulnerabilities found on management systems that are hosted on *.sqills.com. These systems (e.g. Jenkins, Nexus) should not be publicly available.
- applications hosted on *.cloud.sqills.com that are part of another (invite-only) program that has bounties enabled. A finding on this domain may be reported through this program as well. When a report meets the requirements, we will invite you to the bounty program and a bounty will be awarded.
We plan to review our scope each month so make sure to visit regularly or subscribe to our program to receive updates when we make them!
Feedback Would you like to help us improve our program or have some feedback to share, please send your anonymous feedback here: Program Feedback Link Please note this form will be checked periodically and should not be used for submission or support queries.
