Challenge removed


I just solved the rainning blood stego challenge, but when tried to submit the flag I got the message that it is the wrong flag. I find it funny as the flag I found where in the correct format “HTB{flag}”.

So I logged off and logged in again. And the challenge rainning blood is not there anymore.

It is common to have challenges removed? This challenge still available to someone?

Best Regards.

Check the changelog:

As the number of submissions for new challenges continued to increase, and the number of available challenges started to become unmanageable, we made the decision to implement firstly an automated challenge release system, and to implement retirement of old challenges.

Thats explain it. Thanks!

Are writeups for the challenges available (as are machine writeups available for VIPs)?
