Confirmed #2118458: Intentional redirect from www.hackerone.com to domain which is up for sale

P.S.: Actually I submitted this issue back in August 2023 (#2118458), but the domain was just displaying an error. So, I contacted the domain owner for the deal to sell the domain to me and showed you the screenshot of our conversation, but it wasn't considered a valid bug (Even I realized later that it was not a valid proof 😀). **Summary:** There is this endpoint- https://www.hackerone.com/node/9386 which automatically redirects to https://www.iotna.com/. But the domain- **iotna.com** is on sale. ### Steps To Reproduce 1. Open any browser. 2. Visit [this](https://www.hackerone.com/node/9386) link. 3. You will be automatically redirected to https://www.iotna.com/. 4. Observe that the domain is up for sale. {F3218688} {F3218689} ## Impact 1. If anybody obtains the domain, it may use Hackerone as a starting point of the attack and trick users to perform unintended actions, make them download malwares, compromise their systems, etc. 1. Also, it may use this to bypass **External link warning** on hackerone.com submission form ([demo](https://www.hackerone.com/node/9386)) as there is no external warning for https://www.hackerone.com. This is the reason I have set the **Scope** in CVSS to **Changed**. (The domain price is very high, which is why I couldn't provide you with working POC 😃)
