Aircrack, aireplay, airodump, Tutorial crack wep key. Warning, you are only aloud to test out a network with this method if your are the OWNER or if you have a permission of the owner. Hacking is considered breaking a federal law and this tutorial is not meant to help out these purposes, it is simply to sensibilise you to the weekness of your network. I remind to the people who still want to crack their neihboors: YOU NEED AN AUTHORIZATION to crack his network, otherwise, you could be charged or sent to jail.

Aircrack: To test the security of your network, we will need aircrack designed by Christophe Devine. This program works under windows and linux, but some of the functionality are not available under windows (packet injection for example) That is why we will use a linux bootable cd OS: Whax, this distribution is specialized in intrusion tests. Actually the troppix is (in cases little) more up to date talking about wifi drivers and there utilisation is exactly the same. Another list (fr)This tutorial was realized with a D- link DWL- G6. G6. 50 + !!!) , fortunately My neighbour had a livebox (french wifi modem) and autorized me to crack his WEP on his network.

He authorized it thinking I would not succeed. It turned out he was wrong, it took me approximately 2 hours to crack it.

For private property reasons, all the names of the networks (ESSID) were masked except the ones from where the WEP was cracked, that was only partially hidden. The BSSID addresses (mac addresses) also have been partially censured, I only shown the first part of the MACS which correspond to the builder of the card. I repeat if you try to invade a network, you need the authorization from the owner, or you need to be the owner. Whax : Now we are getting serious. So you can fully use your card we will use a live cd of linux (me too, I don’t know anything about the penguin)Get the WHAX distribution here: Download Whax: http: //files.

MAJ : there are new distributions of live cds specialized in monitoring wifi, like troppix and backtrack that are as good or even better. You can found all those distro on files. The functionality is basically identical.

Indeed they all include aircrack and airodump/aireplay. Burn the distrib on a nice cd and put it aside for 2 seconds. On the side I suggest creating a FAT3. The advantage of FAT3.

L0phtCrack attempts to crack Windows passwords from hashes which it can obtain (given proper access) from stand-alone Windows workstations, networked servers, primary.

That partition will be used to stock packets captured and the different files necessary to crack the key. That partition is not required, but it is recommended especially if you have low RAM capacity since the capture files would be stock in RAM (no partition). Also when you have a FAT3. WATCH OUT, YOUR PARTITION WILL NOT HAVE THE SAME NAME UNDER LINUX, SO PLACE A FILE THAT YOU WILL RECOGNIZED IN IT.

After booting on Whax you will end up on a login screen (for troppix you only need to chose video card + keyboard language + resolution)The login is Root and the password is toor, to start the graphical interface, type startx ( you need to type stqrtx since the keyboard will be English, HELL if your reading this ur English =/ so if your stuck with a French keyboard, GET A CLUE You will then end up on the Whax interface. Also, open a shell: The interface is KDE so it is easy to get used to. The monitor mode lets us capture packets transiting even the ones that aren’t directed to you.

For my part I type in « cd . The BSSID column corresponds to the Mac addresses of the access points (AP)The ESSID colujmn corresponds to the name of the network (My. Wifi. Networw, Wanadoo- xxxx..) The first part corresponds to the access points and the second part to the stations ( the computers that are logged in)The column that interests us is the one that has IVs, those are the files that will allow us to crack the WEP keys. Here the AP of my friend is the only one where the ESSID is not totally masked. For better performances in the capture of packets, we re lunch airodump chosing only the canal where the AP is (here is 1.

To stop the capture and enter commands do Ctrl + C. You are also obligated to stop the capture if you want to copy a mac address since the screen refreshes. To copy something simply select with the mouse and right click copy. Idem to paste or use Shift+insert. By experience the IVs capture is a lot faster, and also they need to be diversified since the crack will need less IVs’s. Pokemon Fire Red Download For Dsi Emulator.

For example here there is traffic, but unfortunately there wasn’t any after so I had to capt a lot of IVs before finding the key. Aireplay : In detail in the aireplay manual Just like airodump, aireplay is part of aircrack. Fake authentication. See the FAQ aireplay - 1.

To launch aireplay open another console in the same screen with the help of the little icon on top left. You can also rename it with a right click. We launch aireplay once without worrying about the bssid of the station : The parameters are: “ aireplay - 1 0 –e .

Here we can see that if we place a dummy mac address the AP refuses us, but if we put the BSSID that airodump gives us it works. Some of the AP don’t have any filtering of MAC addresses and you can put any MAC address. Once you have “ association successful “ it is a first victory, basically you are accepted by the access point wifi. It is possible that if you don’t capt the signal (if the power is low ) that the authentication is successful and the association is not immediate. Here the example is small but you can easily have 4. SHere is a small scheme that will show you the relations between the parameters of aireplay and the capture of airodump : The association is not really reliable and if it fails, you can still go through the next step. Packet Injection : In detail aireplay attack - 3 Once the association is good, we relaunch aireplay changing some of the parameters.

You need to change the first parameter by “- 3” that corresponds to an attack by packet injection. Then you need to add the parameter “- x” following a value that corresponds to the number of packets per seconds that aireplay will send. Here it is 6. 00, Depending on the AP signal strength modify the parameter. Also, following the capture file (airodump) add in the parameter –r. This parameter indicates in which file read to see if there are ARP’s inside. The ARPS are what will allow us to influence the traffic.

DON’T FORGET TO PLACE YOURSELF IN THE SAME DIRECTORY To avoid to type it all, since the syntax is basically the same then the parameter - 1 press the up arrow key to have what you have previously entered. Aireplay saves ARPS in a file that he makes every time it is launched. It is underlined in the picture.

That file finds itself in the folder where you lauched aireplay It is that file that you then put in the parameter –r if you got ARPS, the ARPS are obtained by reading the file indicated but also by listening the the network, like airodump does. Here, we can see that we have an arp. And normaly if everything is going well, the IVS grow. And it is the case, they are growing : D: At the sime time, the arps also go up: Au maximum aireplay garde 1. ARP. To give you an idea of the speed for capting IVs’s I did some print full screen, look at the clock.

At 1. 6h. 25 1. 90 0. IVs. At 1. 6h. 30 2. IVs. At 1. 6h. 43 6. IVs. 4: // Aircrack : In detail in the FAQKnow that you need approximately 3. IVs for a 6. 4 byte WEP key and about 1 mil for a 1. WEP key, it is pretty fast.

You should launch Aircrack once you have 3. For that in the parameters of aircrack, you only need to add –n 6.

WEP key as if it was a 6. WEP key, even if it is a 1. Personaly this tuto aimed a 1. I don’t send it with 6. But since I have approximately 7. I can start to launch aircrack while the capture of packets is still going on with airodump.

Open a new shell and launch aircrack. Don’t forget to place yourself in the folder containing the files of airodump, if you have created a FAT3.
