"packet sniffer", software available on the Internet, along with other freeware or shareware hacking
utilities
available on the Internet, to acquire your WEP keys and other network information to defeat
security.
Jamming Attacks
Jamming Attacks, when a powerful signal is sent directly into your wireless network, can
effectively shut down
your wireless network. This type of attack is not always intentional and can often come about
simply due to the
technology. This is especially possible in the 2.4 GHz frequency, where phones, baby monitors,
and microwave
ovens can create a great deal of interference and jam transmissions on your wireless network.
One way to
resolve this is by moving your wireless devices into the 5 GHz frequency, which is dedicated solely
to information
transmissions.
Active Attacks
Hackers use Active Attacks for three purposes: 1) stealing data, 2) using your network, and 3)
modifying your
network so it's easier to hack in the next time.
In an Active Attack, the hacker has gained access to all of your network settings (SSID, WEP keys,
etc.) and is in
your network. Once in your wireless network, the hacker has access to all open resources and
transmitted data
on the network. In addition, if the wireless network's router is connected to a switch, the hacker will
also have
access to data in the wired network.
Further, spammers can use your Internet connection and your ISP's mail server to send tens of
thousands of
e-mails from your network without your knowledge.
Lastly, the hacker could make hacking into your network even easier by changing or removing
safeguards such
as MAC address filters and WEP encryption. He can even steal passwords and user names for the
next time he
wants to hack in.
Dictionary-Building or Table Attacks
Dictionary-building, or Table attacks, is a method of gaining network settings (SSID, WEP keys,
etc.) by analyzing
about a day's worth of network traffic, mostly in the case of business networks. Over time, the
hacker can build
up a table of network data and be able to decrypt all of your wireless transmissions. This type of
attack is more
effective with networks that transmit more data, such as businesses.
Man-in-the-Middle Attacks
A hacker doesn't need to log into your network as a user - he can appear as one of the network's
own routers,
setting himself up as the man-in-the-middle. To do this, the hacker simply needs to rig an router
with your
network's settings and send out a stronger signal that your router. In this way, some of your
network's PCs may
associate with this rogue router, not knowing the difference, and may begin sending data through
it and to this
hacker.
The trade-off for the convenience and flexibility wireless networking provides is the possibility of
