Hi rwthCTF Teams,
 
−
 
−
with this message, the first ever rwthCTF is officially in the "team-preparation" phase. Attached to this mail you can find the first instructional README.txt file, a rough diagram of our network setup and a second document (codewars.txt) that serves as a small appetizer for the upcoming challenges in the CTF. The appetizer (codewars documentation) only describes a small part of the CTF event - we will have lots of programming languages and skill areas covered. Also the scripts mentioned in the document will only be made available when the competition starts.
 
−
 
−
Additionally we prepared a "test-vulnbox" that can be downloaded from the link below. This is _NOT_ the final vulnbox image. Please refer to the README for further pointers. You will need this once VPN credentials are released - probably on next Monday (again see README).
 
−
 
−
This E-Mail is signed with a PGP key and sent in PGP/MIME. Please download the corresponding public key from http://ctf.itsec.rwth-aachen.de/ and verify the signature. All further mail communication from rwthCTF organizers will be signed with this key as well.

Cheers,

Hi rwthCTF Teams,
 
−
 
−
with this mail you get your VPN credentials. This includes the openvpn config
 
−
file (client.conf), your team certificate (teamX.cert) and your private key
 
−
(teamX.key). Also needed by OpenVPN and attached to this mail are the CA
 
−
certificate "rwthctfca.pem" and a TLS shared key "ta.key". These credentials can
 
−
only be used from _ONE_ machine at a time.
 
−
 
−
The X in the files you receive is your team ID. This also specifies your IP
 
−
subnet 10.11.X.0/24! Please refer to the earlier README.txt for further details.
 
−
 
−
Please connect to the VPN, set your IP addresses and bring up your routing. Also
 
−
start the Test Vulnbox and set it to 10.11.X.2.
 
−
 
−
You can view a preliminary scoreboard at http://10.11.0.1/ During the CTF we
 
−
allow flag submission at 10.11.0.1 port 1/tcp. This should already be online for
 
−
testing purposes, but you can not score any points before the CTF starts on
 
−
September 30th. The rest of the network is pretty locked down at the moment -
 
−
you may ICMP, though.
 
−
 
−
Any further questions should be asked via E-Mail or the #rwthctf IRC channel on
 
−
freenode.
 
−
 
−
One last thing: each team was assigned a unique secret passphrase (secret.txt)
 
−
that is needed for certain critical actions during the competition. Keep it
 
−
safe!
 
−
 
−
Cheers,
 
−
-rwthCTF Orga
