UCSB CTF 2004

A team of hackers (known as "0ld Eur0pe"), mainly consisting of the Summerschool Aachen 2004, members of the Chaos Computer Club Cologne and some students of the RWTH[1], participated in the UCSB Capture The Flag 2004 game and were quite successful (see the scoreboard[2], second line).

This page serves as a whiteboard to document the setup we used this year and to collect ideas about what we can do better next time.

Setup

What To Do Better

General

• don't put such a strong focus on host and network security again, this game was about application security
• use some means of internal communication (wiki?)
• split teams into research/abuse instead of attack/defense (Research would read code, produce new exploit and fix bugs, Abuse would automate and use exploits) (?)
• start earlier
• get more hardware boxes which could be used for monitoring and firewalls

VMWare Game Image Security

Check for

• ssh pubkeys
• sshd configuration:
  • PubKeyAuthentication
  • PermitRootLogin
• nfs exports
• user passwords
• PHP Safe Mode?

Pics!

Where are the pictures people made during the event? Where can I download the video somebody created?
