I’m new here, and so far really enjoying it (just got my first root flag, on the Bastion machine) but I’m struggling to find a place for something I’d like to submit for others to try and hack.
I’ve created a Windows VM that has various exploitable aspects along with some flags to capture, but the problem is for some of the priv escalations the files on the machine would have to be modified… so this wouldn’t work if multiple people are trying to hack it at once (which I believe is how all of the VMs listed in the Machines section work, but correct me if I’m wrong and there’s some way for people to all get their own instance).
I looked at the Challenges section and whilst there are some downloadable ones, they all seem to be small files rather than VMs.
So is there anywhere on this site I can submit such a VM for others to try hack, or is that just not an option here? If not, is it possible to upload the VM elsewhere and at least start a thread here for people to discuss how they’re getting on with it or is that not allowed?
