LINUX DISTRIBUTIONS

The most known is backtrack versions(3 and 4) i will use backtrack4 another distributions wifiaway,wifislax.,everyone of them its specialase in auditoria of wireless network with a lot of programas like: airodump-wireles network scanner aircrack-its use to crack wep pass wireshark-internet traffic escanner It is a simple 3 examples of 3 programs from linux distributions you ask me how did this work how a hacker can use this to penetrate my wireless network: first one we need to download backtrack4http://www.backtrack-linux.org/ this is the link were you can download any backtrack you wish,try with live cd you can install backtrack into your sistem using a virual machine like VMWARE http://www.vmware.com/ this is the oficial site of vmware you need to download wmware workstation 7 you can use 30 days this program afree if you will subscrib (its free)i will put a video on youtube about how to run backtrack4 in vmware its very simple to do this. The youtube movie its show you how can a hacker crack a wireless network(wep key). The second video its about how can you run backtrack4 in vmware its very simple

SNIFFING PROGRAMS

Once penetrade the network the hacker can use snnifing programs such as cain&abel, wireshark,to see the internet trafic into the network with the final goal to steal your passwords. For now i will present only this two programs: cain&abel-its a complex program how has a sniffing tool and a crack tool. The basic idea in the traffic interceptation is that the attacker is interposed between the router and pc atacked so that traffic passes to the attacker pc first and then go to the router,this is the basic idea.i will put an video on this program,one more thing-i use this program under windows. wireshark-its almoust the same tipe that the first one but in this you will need to process a huge cantitate of data.This one its cames with backtrack4 but also can you use under windows.

WHAT CAN WE DO?

As you can see the tools hackers are diverse and complex as I illustrated above and is only a small part of the multitude of ways that we can be attacked, I think we should show more interest in everything around us and especially to new Wireless technology is the future because I believe that the transmission and receipt of data. How can we defend against these attacks, I have some advice: -If you have a wireless router and its has an wep key to have acces change it into an wpa key(choose a key that is not into the dictionary -phone number f.g) -check if at yor network are conected other pc that you know it If you connect through a public Internet network try to keep on mind that someone can spy on you and he can see what password that you type so dont type important psswords(such paypal pass)

compatible wireless cards - audit and monitoring network

There are two manufacturers involved with wireless cards. The first is the brand of the card itself. Examples of card manufacturers are Netgear, Ubiquiti , Linksys and D-Link. There are many, many manufacturers beyond the examples give here.

The second manufacturer is who makes the wireless chipset within the card. This is the most important company to know. Unfortunately, it is sometimes the hardest to determine. This is because card manufacturers generally don't want to reveal what they use inside their card. However, for our purposes, it is critical to know the wireless chipset manufacturer. Knowing the wireless chipset manufacturer allows you to determine which operating systems are supported, software drivers you need and what limitations are associated with them. The compability section describes the operating systems supported and limitations by chipset.

You first need to determine what wireless chipset your card uses. This can be done by one or more of these techniques:

*
Search the internet for ” chipset” or ” linux”. Quite often you can find references to what chipset your card uses and/or other people's experiences.
*
Search the Forum
*
You may also have a look at windows driver file names, it's often the name of the chipset or the driver to use.
*
Check later in this page for cards known to work with aircrack-ng
*
Check the card manufacturers page. Sometimes they say what chipset they use.
*
Have a look at lspci -vv output for descriptions, PCI id and kernel modules used.
*
Locate the FCC ID of your device. Enter the information into FCC Website and then browse the internal photos of the device.
