Hi All,
We can suppose that we should get into interaction with mentioned site: https://beep-boop.ctf.ritsec.club/
After quick manual checking, you will get to know that there is not interesting item — the Flag (from CTF task point of view).
For example ‘About us’ gives “https://geometrydash.io/about-us” which is external page (versus “https://beep-boop.ctf.ritsec.club”).
Let’s make little bit larger our manual recon here — check [/robots.txt](https://en.wikipedia.org/wiki/Robots.txt)
So, take a look at https://beep-boop.ctf.ritsec.club/robots.txt
Good idea! Exists. We can see there:
```
“User-agent: *
Disallow: / # Disallow all robots from indexing any content
UlN7ZzMwbTJ0eV9kQHNoXyFzX2whZjN9"
```
Now, you can use [CyberChef](https://gchq.github.io/CyberChef/) tool for instance:
Source: CyberChef
You can see that [Base64](https://en.wikipedia.org/wiki/Base64) was used there.
In the same while, you can get a Flag!
Flag: **RS{g30m2ty_d@sh_!s_l!f3}**
I hope you enjoy!
