Sorry for the downtime, wasn’t planned. It was late last night when I set up the knock daemon, I somehow managed to accidently copy and past my terminal which resulted in about a quarter of my /etc/init.d/* scripts getting broken. Unfortunatly I didn’t notice it right away. I did notice it when I rebooted the server (kernel change) and lot’s of daemons didn’t come up (oh unimportant stuff like SSH 🙁 ) Well, that’s what backups are for.
Ok, the contest is ready. I’ll start off with the information everybody has been waiting for:
IP: 80.190.250.213
There is a webserver running with a brief description of the target and rules of the contest http://80.190.250.213/ The webserver is actually part of the contest since people are supposed to deface this page. To make it a bit more interresting, the ssh sessions are recorded with script and saved here for everyone to see (e.g. “less -r filename”).
Rules and Target of the contest:
As stated above, deface this page. To achieve this goal, everything is allowed. Do what you need/want to achieve the goal.
Unfortunatly we will still need a short list of actions that are not allowed:
A few details to the box and the system:
Have fun 😉
btw. I’m also posting this in the buha forums for anyone who prefers a German description.
I spent the last few days fine tuning the HackIt server I mentioned last week. After lots of thought on how I was going to punch holes into the security, I decided on a different approach. Since in the past contests I always found it fustrating to see people with high skills trying out stuff I would never have dreamed of, and in the end to get beaten by people who by sheer luck tried out the right thing at the right time … I decided to minimize the “luck” factor of the contest by not putting any holes in the server on purpose.
What I am going to do is not update any of the packages any more from now on. I’m doing an update right now as I post this, and from here on no more updates. There will also be no updates or changes to the RBAC system. The only changes I will be making to the box from now on, are if it breaks and needs to be fixed.
-> The box will be shamelessly neglected, waiting to be owned.
If nothing strange pops up tonight, I will be posting information about the contest tomorrow in the buha forum, here and a few other places …
The last HackIt I set up was a few years ago, so I decided to have a go at it again. As before it will be a Linux server. And I will also have some fun with grsecurity kernel patches (including the additional Role-Based Access Control system). So nothing new up to here. I’m also going to be using most of the features I used back then too (like “trusted path execution” and no outgoing/server sockets for users, …)
Last time it was separate hardware on my little DSL line (meaning back then all users had to share a 128kbit upstream). This time it will be a vmware box on a 100Mbit Internet connection and it’s own IP, so no more worry about laggy ssh sessions.
I’ll post more details as soon as this gets more “ready-for-release”. Right now I’m still hardening the box, I still haven’t decided on which holes I’m going to build into it to make it a “HackIt”.
