Hackthebox invite challenge


Checked the source code nothing

Check the requests nothing like a parameter there

So one js caught my attention

Use a js beautifier and saw a json response which says sent a post request to api/invite/how/to/generate

Then I got a ROT13 encoded text.. decode it with

Echo “rot13 text” | tr '[A-Za-z]' '[N-ZA-Mn-za-m]'

Got an output saying send a POST request to /api/invite/generate and yeah I got another json parameter in the request response, this time around it was a base64 encoded text. But if you not sure which hash the code you get is, use “" to get the hash that your code is, now that I know the hash is a base64 encoded hash. I decoded it using echo “base64 text” | base64 —decode

And here I got my invite code.
