Code of Ethics for Security Professionals
  • Act with honesty, integrity and professionalism
    at all times.
  • Personal curiosity is not an excuse to break the
    law.
  • Respect the power of information and be willing
    to share your knowledge for the advancement of
    the security field and the protection of society.
  • Honor and maintain the confidentiality of all
    client information that may be discovered during
    the course of an engagement.
  • Remember that even the smallest appearance of
    impropriety may result in damage to your
    reputation and the credibility of our profession.
  • If a little voice in your head tells you that you
    might not be doing the right thinglisten to that
    voice.

Why Do People War Drive?
Good guys and not so good guys
  • Because its fun
  • To learn about wireless technology
  • Looking for a place to check e-mail
  • Defending our network/Look for rogue APs
  • To gain unauthorized access / launch attacks /
    other criminal activity

Antenna Basics
Antennas do not amplify the signal they merely
focus the energy in a particular direction.

Antenna Basics
Antennas - Isotropic
Isotropic antenna A hypothetical antenna that
radiates or receives equally in all directions.
Note Isotropic antennas do not exist physically
but represent convenient reference antennas for
expressing directional properties of physical
antennas.

Whats the problem with RF?
  • Wireless signals dont STOP at your walls.
  • Wi-Fi is like putting an Ethernet jack in your

Wardriving Built-In to XP?
Source http//www.infoworld.com/articles/op/xml/0
2/07/22/020722opcurve.xml Snippet For all his
success at bringing Microsoft's warring
constituencies together, there are still things
beyond Bill and Steve's control. "I was in a
hotel in Sun Valley last week that was not
wired," Ballmer recalls. "So I turned on my PC,
and XP tells me there is a wireless network
available. So I connect to something called
Mountaineer. "Well, I don't know what that is.
But I VPN into Microsoft. It worked! I don't know
whose broadband I used," he chuckles. "I didn't
see it in Bill's room. I called him up and said,
'Hey, come over to my room.' So soon everyone is
there and connecting to the Internet through my
room."

Stumbler Code of Ethics v0.1
http//www.renderlab.net/projects/wardrive/ethics
.html By Renderman,
Render_at_Renderlab.net
These are by no means rules that must be
followed, but they are a collection of
suggestions for safe, ethical, and legal
stumbling. I encourage you to follow them.
1. Obey traffic laws. It's your community too,
the traffic laws are there for everyone's safety,
besides, doing doughnuts at 3am gets unwanted
attention from the authorities. 2. Obey private
property and no-trespassing signs. Don't trespass
in order to scan an area. That's what the
directional antenna is for ) You wouldn't want
people trespassing on your property would you? 3.
Don't connect. The vast majority of AP's out
there were not intended by their owners to be
accessed by you, even if they configured it so
you could access it if you wanted to. There is
much legal question as to the trouble you can get
into for accessing a network through a
misconfigured AP. Also it's a matter of respect,
you wouldn't want people rooting through your
computers just because you happened to make a
mistake, so don't do it to them. 4. Don't use
your data for personal gain. Share the data with
like-minded people, show it to people who can
change things for the better, but don't try and
make any money or status off your data. It's just
wrong to expect these people to reward you for
pointing out their own stupidity. 5. Don't
warchalk Other peoples networks. Only chalk your
own if you want to indicate your willingness to
share access. If you chalk some strangers
network, it dilutes the use of the symbols to
indicate free access. If youre a business and
you have a public AP and a non-public one,
indicate with the open one, but also indicate the
closed one with the closed symbol,
differentiating them so people know the
difference. 6. Be like that hiker motto 'Take
only pictures, leave only footprints'. Stumblers
should 'Take only SSID's, leave only tire marks'.
Leaving tire marks by not loitering and moving
on is better than leaving a log entry by doing
something stupid.

Summary
  • Wireless signals dont stop at your walls
  • Use an omni antenna
  • When choosing a WLAN card
  • What chipset does it use?
  • Is there an external antenna connector?
  • Use Netstumbler/Kismet/dStumbler
  • Or, a protocol analyzer
  • Dont forget to unbind your TCP/IP stack!!!
