DefCon Survival Guide

Rules to Live By

1. Do not use the ATM's at or in the close vicinity of the Riveria

2. Secure cellphones as best as possible

a. Do not connect it the wireless network

b. Bluetooth and other non-essential communications mechanisms should be off

c. Not physically visible during the conference

d. Store phones in a secure location where it will not fall out and possibly fall into the possession of someone else. In fact do this for any personal item of value.

3. Do not use any credentials on websites without encryption throughout the entire conference (see sidejacking)

a. Dynamic port forward all your traffic through a properly configured SSH tunnel

b. Use a VPN tunnel for all traffic

4. Do not take unauthorized DefCon pictures in the contest area or in the CTF area

5. Do not give away valuable information (utilize constant vigilance)

6. Do not attach a work machine or a machine with valuable information to the DefCon network

7. Do not accept “Free” devices to attach to a machine (e.g. a free USB key from another attendee)

8. Do not antagonize anyone with a “Goon” or higher-level attendee badge

9. Shower. Seriously, please shower. I've said it once, I'll say it again, poor hygene does not make anyone a better hacker.

10 In fact please read and adhere to the do's and don'ts of personal presentation at conferences written by Shyama Rose, who is a well-known, knowledgeable, intelligent security professional who also happens to be quite good looking e.g. the dream girl of many of the non-showering types.


Navigating the Wall-of-Sheep

The Wall-of-Sheep is a team at DefCon who is authorized to connect to the DefCon network core router spanning port. This means that the Wall-of-Sheep is able to view all of the DefCon network traffic. Typically this team leverages a Sourcefire IDS as well as various utilities to monitor the DefCon network and publicly display the usernames and portions of passwords of anyone silly enough not encrypt their traffic. Put sim ply, it sucks to be put on Wall-of-Sheep, it's really embarrassing, you don't want to be a sheep.

That said the Wall-of-Sheep can be a great learning opportunity as well. The Wall-of-Sheep team allows attendees to plug into the spanning port and monitor as well. In order to participate in the Wall-of-Sheep simply sit down at a Wall-of-Sheep table and ask for a connection. Be sure to sit on the outside of of the circle of tables as the Wall-of-Sheep team wishes to maintain a barrier between unknown attendees and their equipment.

Once attached to the DefCon network spanning port, begin sniffing traffic for usernames and passwords. If you find a username/password, write it down on a piece of paper and deliver it to the person who is manually entering them into the displayed Wall-of-Sheep scrolling site.


 

Useful Utilities for the Wall-of-Sheep

Wireshark – Wireshark can be a useful too for sniffing packets on the Wall-of-Sheep, however, be warned the DefCon network will most likely overwhelm your machine.

Dsniff – Dsniff is an excellent tool for capturing usernames and passwords. Simply run Dsniff by typing “dsniff.” It should take it from there.

Tcpdump – Tcpdump is a great tool for capturing traffic that most are familiar with. However, because of the large volume of DefCon traffic be sure to leverage tcpdump switches to reduce the notice.

Ettercap –  Ettercap is another great tool for sniffing traffic (and poisoning switches). Simply run Ettercap with the proper switches and it will begin listing usernames/passwords as they cross the wire

NetWitness Investigator – Awesome full-packet capture utility that will sort captured traffic. Unfortunately the free version will only process 1 GB of data at a time. This means that a user has roughly one minute of traffic on the DefCon network.

Snort – Easy full-packet capture and useful IDS rules to run it by

Etherape – Graphical representation of traffic, won't tell you much but it will show you how much traffic is passing

CAIN (Note some Web Content Filters block oxid.it as a malware site)– If you feel so inclined to use windows, CAIN is a pretty good sniffing tool


 

Know the Groups

303 Group – Hackers from Denver, Colorado. There are usually a lot of these guys.

Pauldotcom – Group of security podcasters from PaulDotCom.com good group, great podcast.

Shmoo Group – Awesome group, used to put out a lot of useful utilities, today they are less active outside of ShmooCon, which is awesome.

Hackers For Charity – Johnny Long's not-for-profit charity group. These guys will be everywhere, some of them will be identifiable by shirts that say, “I hack charities.” (hackersforcharity.org)

IRC People – These people are usually identifiable by the fact that still introduce themselves with a handle

Church of the Wifi – A bunch of Wifi hackers

Hacker Pimps -  A hacker and research group. Also coordinate DC905 and Jacksonville 2600

Wall-of-Sheep – People sniffing packets and stealing passwords to display to the rest of DefCon

EFF – Lawyers who often times take up hacker type cases

OWASP/OWASC – Open Web Application Security Project/Open Web Application Security Consortium folks. These folks from (OWASP.org and OWASC.org respectively) are knowledge leaders in web application security. These guys tend to be bigger at BlackHat but a lot of them will still be around at DefCon.


 

Navigating the Conference Venue

Notice on the map that the halls are small. These halls, with 10,000 people in them get frustrating with how cluttered they get. Keep in mind that there are doors you can get into and out of by walking outside at the foyer and directly in front of speaker track rooms 1-4 (Royale Pavilion). Thus, if you should find yourself in the Grande Ballroom area and needing to get to Royale Pavilion during so-called rush hour (time in between tracks), go outdoors, it's so much faster!
