About the tool:

• This tool serves as a little utility which allows a bug bounty hunter to discover who gave him a duplicate on his HackerOne report.
• As a result he may get in contact with the hunter or eventually hire a hitman on him! (for legal reasons this is a joke)

Note: For this tool to work the report you got a duplicate on has to be in resolved state.

How to get the needed parameters:

• --program_name - You can get this simply by looking at the URL of the targeted BBP:

• --h1_session - The purpose of this one is for private programs, which is a bit annoying sadly, but you can follow these steps to get it:

1. Open https://hackerone.com while logged-in.
2. Open Chrome DevTools -> Application
3. Inside the Cookies section find the __Host-session cookie and copy it:

• --report-id - This is just the report you got duped to, which is the reason why you're looking at this tool in the first place. Anyways you can find it in your report like this:

Special Thanks:

• Dexter0us for letting me know about this trick in the HackerOne GraphQL API.

TODO:

• Add concurrency for more speed.
• Add the possibility to automatically get all duplicated report IDs for a program and dump info for all.
• Add a debug -v mode
