Aircrack- ng]. Version: 1. March 0. 7, 2. 01. By: dark. Audax. This tutorial walks you through cracking WPA/WPA2 networks which use pre- shared keys.
How To Crack WEP and WPA Wireless. WPA hashes the network key using the wireless access point. Others posting here are helping each other hack private.
I recommend you do some background reading to better understand what WPA/WPA2 is. The Wiki links page has a WPA/WPA2 section. The best document describing WPA is Wi- Fi Security - WEP, WPA and WPA2.
This is the link to download the PDF directly. The WPA Packet Capture Explained tutorial is a companion to this tutorial. WPA/WPA2 supports many types of authentication beyond pre- shared keys. ONLY crack pre- shared keys. So make sure airodump- ng shows the network as having the authentication type of PSK, otherwise, don't bother trying to crack it. There is another important difference between cracking WPA/WPA2 and WEP. This is the approach used to crack the WPA/WPA2 pre- shared key.
Unlike WEP, where statistical methods can be used to speed up the cracking process, only plain brute force techniques can be used against WPA/WPA2. That is, because the key is not static, so collecting IVs like when cracking WEP encryption, does not speed up the attack. The only thing that does give the information to start an attack is the handshake between client and AP. Handshaking is done when the client connects to the network. Although not absolutely true, for the purposes of this tutorial, consider it true. Since the pre- shared key can be from 8 to 6.
The only time you can crack the pre- shared key is if it is a dictionary word or relatively short in length. Conversely, if you want to have an unbreakable wireless network at home, use WPA/WPA2 and a 6. The impact of having to use a brute force approach is substantial. Because it is very compute intensive, a computer can only test 5.

CPU. It can take hours, if not days, to crunch through a large dictionary. If you are thinking about generating your own password list to cover all the permutations and combinations of characters and special symbols, check out this brute force time calculator first. You will be very surprised at how much time is required. IMPORTANT This means that the passphrase must be contained in the dictionary you are using to break WPA/WPA2. If it is not in the dictionary then aircrack- ng will be unable to determine the key. There is no difference between cracking WPA or WPA2 networks.
The authentication methodology is basically the same between them. So the techniques you use are identical. It is recommended that you experiment with your home wireless access point to get familiar with these ideas and techniques. If you do not own a particular access point, please remember to get permission from the owner prior to playing with it.
I would like to acknowledge and thank the Aircrack- ng team for producing such a great robust tool. Please send me any constructive feedback, positive or negative. Additional troubleshooting ideas and tips are especially welcome. First, this solution assumes. You are using drivers patched for injection.

Use the injection test to confirm your card can inject. You are physically close enough to send and receive access point and wireless client packets.
Remember that just because you can receive packets from them does not mean you may will be able to transmit packets to them. The wireless card strength is typically less then the AP strength.
So you have to be physically close enough for your transmitted packets to reach and be received by both the AP and the wireless client. You can confirm that you can communicate with the specific AP by following these instructions.
You are using v. 0. If you use a different version then some of the command options may have to be changed.
Ensure all of the above assumptions are true, otherwise the advice that follows will not work. In the examples below, you will need to change “ath. In this tutorial, here is what was used.
MAC address of PC running aircrack- ng suite: 0. F: B5: 8. 8: AC: 8. MAC address of the wireless client using WPA2: 0. F: B5: FD: FB: C2. BSSID (MAC address of access point): 0.
C: 7. E: 4. 0: 8. ESSID (Wireless network name): teddy. Access point channel: 9. Wireless interface: ath. You should gather the equivalent information for the network you will be working on. Then just change the values in the examples below to the specific network.
Solution. Solution Overview. The objective is to capture the WPA/WPA2 authentication handshake and then use aircrack- ng to crack the pre- shared key. This can be done either actively or passively. Actively” means you will accelerate the process by deauthenticating an existing wireless client. Passively” means you simply wait for a wireless client to authenticate to the WPA/WPA2 network. The advantage of passive is that you don't actually need injection capability and thus the Windows version of aircrack- ng can be used.
Here are the basic steps we will be going through. Start the wireless interface in monitor mode on the specific AP channel Start airodump- ng on AP channel with filter for bssid to collect authentication handshake Use aireplay- ng to deauthenticate the wireless client Run aircrack- ng to crack the pre- shared key using the authentication handshake. Step 1 - Start the wireless interface in monitor mode. The purpose of this step is to put your card into what is called monitor mode.
Monitor mode is the mode whereby your card can listen to every packet in the air. Normally your card will only “hear” packets addressed to you. By hearing every packet, we can later capture the WPA/WPA2 4- way handshake. As well, it will allow us to optionally deauthenticate a wireless client in a later step. The exact procedure for enabling monitor mode varies depending on the driver you are using.
To determine the driver (and the correct procedure to follow), run the following command. On a machine with a Ralink, an Atheros and a Broadcom wireless card installed, the system responds. Interface Chipset Driver. Ralink RT7. 3 rt. Broadcom b. 43 - [phy. Atheros madwifi- ng. Atheros madwifi- ng VAP (parent: wifi.
The presence of a [phy. Broadcom card is using a mac.
Note that mac. 80. Both entries of the Atheros card show “madwifi- ng” as the driver - follow the madwifi- ng- specific steps to set up the Atheros card. Finally, the Ralink shows neither of these indicators, so it is using an ieee. Step 1a - Setting up madwifi- ng. First stop ath. 0 by entering. The system responds.
Interface Chipset Driver. Atheros madwifi- ng.
Atheros madwifi- ng VAP (parent: wifi. VAP destroyed). Enter “iwconfig” to ensure there are no other ath. X interfaces. It should look similar to this. If there are any remaining ath.
X interfaces, then stop each one. When you are finished, run “iwconfig” to ensure there are none left. Now, enter the following command to start the wireless card on channel 9 in monitor mode. Note: In this command we use “wifi. This is because the madwifi- ng drivers are being used. The system will respond. Interface Chipset Driver.
Atheros madwifi- ng. Atheros madwifi- ng VAP (parent: wifi. You will notice that “ath. To confirm the interface is properly setup, enter “iwconfig”. The system will respond. IEEE 8. 02. 1. 1g ESSID: "" Nickname: "". Mode: Monitor Frequency: 2.
GHz Access Point: 0. F: B5: 8. 8: AC: 8. Bit Rate: 0 kb/s Tx- Power: 1.
Bm Sensitivity=0/3. Retry: off RTS thr: off Fragment thr: off.
Encryption key: off. Power Management: off. Link Quality=0/9.
Signal level=- 9. Bm Noise level=- 9. Bm. Rx invalid nwid: 0 Rx invalid crypt: 0 Rx invalid frag: 0. Tx excessive retries: 0 Invalid misc: 0 Missed beacon: 0. In the response above, you can see that ath. GHz frequency which is channel 9 and the Access Point shows the MAC address of your wireless card. Only the madwifi- ng drivers show the card MAC address in the AP field, other drivers do not.
So everything is good. It is important to confirm all this information prior to proceeding, otherwise the following steps will not work properly. To match the frequency to the channel, check out: http: //www.
US/docs/wireless/technology/channel/deployment/guide/Channel. This will give you the frequency for each channel. Step 1b - Setting up mac. Unlike madwifi- ng, you do not need to remove the wlan. Instead, use the following command to set up your card in monitor mode on channel 9. The system responds. Interface Chipset Driver.
Broadcom b. 43 - [phy. Notice that airmon- ng enabled monitor- mode on mon. So, the correct interface name to use in later parts of the tutorial is mon. Wlan. 0 is still in regular (managed) mode, and can be used as usual, provided that the AP that wlan. AP you are attacking, and you are not performing any channel- hopping.
To confirm successful setup, run “iwconfig”. The following output should appear. IEEE 8. 02. 1. 1bg ESSID: "". Mode: Managed Frequency: 2. GHz Access Point: Not- Associated.
Tx- Power=0 d. Bm. Retry min limit: 7 RTS thr: off Fragment thr=2.
B. Encryption key: off. Power Management: off. Link Quality: 0 Signal level: 0 Noise level: 0.
Rx invalid nwid: 0 Rx invalid crypt: 0 Rx invalid frag: 0. Tx excessive retries: 0 Invalid misc: 0 Missed beacon: 0.
IEEE 8. 02. 1. 1bg Mode: Monitor Frequency: 2. GHz Tx- Power=0 d. Bm. Retry min limit: 7 RTS thr: off Fragment thr=2. B. Encryption key: off.
Power Management: off. Link Quality: 0 Signal level: 0 Noise level: 0.
Rx invalid nwid: 0 Rx invalid crypt: 0 Rx invalid frag: 0. Tx excessive retries: 0 Invalid misc: 0 Missed beacon: 0. Here, mon. 0 is seen as being in monitor mode, on channel 9 (2.
GHz). Unlike madwifi- ng, the monitor interface has no Access Point field at all. Also notice that wlan.
Because both interfaces share a common radio, they must always be tuned to the same channel - changing the channel on one interface also changes channel on the other one. Step 1c - Setting up other drivers.
For other (ieee. 80. The system responds. Interface Chipset Driver. Ralink rt. 73 (monitor mode enabled). At this point, the interface should be ready to use. Step 2 - Start airodump- ng to collect authentication handshake.
