Wpa hacking

Create a network interface which runs in monitor mode. To do this enter command airmon-ng start wlan0. Make sure to replace wlan0 in command with the interface name that your card have. Here, mon0 has been created. Now, you might or might not get the warning appearing in the below screenshot which tells other processes using the network which can create the problem.

So, you can kill them using the syntax: kill PID if you know those processes are not important for you at the moment. It can take time to all the available WiFi networks in range. First enter the command airplay-ng -1 0 -a FB:A9:B1 mon0 to perform fake authentication -1 in command to the network. Hit enter and the command will start doing attack to WEP WiFi Access point and you can see the Data value increasing at enormously fast rate.

In below screenshot the bell Once you have enough data in the file bell It will test all the data values available in key file and automatically show you the key it found by testing data in file. It will be in hex format but work just fine.

Now, to use this key, firstly start the processes you have killed in Step 1 above using the command I have used below. Finally enter the cracked key without colon as the password of targeted WEP WiFi Network and it will be connected.

Plug your Wi-Fi card if needed. In most cases, simply attaching the card to your computer will be enough to set it up.

Check the instructions for your Wi-Fi card to be sure. If you're not sure if your Wi-Fi card supports monitoring, it doesn't hurt to try these next few steps. Disconnect from Wi-Fi. To successfully test a network, you'll want to make sure your computer is not actively connected to Wi-Fi—not even to the network you're testing. In a terminal window, run the airmon-ng command. This tool come with Kali Linux as a part of the aircrack-ng package, and will show you the names of the connected Wi-Fi interface s.

You'll want to take note of what you see under the "Interface" header for your card. If you don't see an interface name, your Wi-Fi card doesn't support monitoring. Run airmon-ng start wlan0 to start monitoring the network.

If the name of your Wi-Fi interface isn't wlan0 , replace that part of the command with the correct name. This gives you a new virtual interface name, which will usually be something like mon0 , which you'll see next to " monitor mode enabled.

Run airodump-ng mon0 to view the results. Replace mon0 with the correct virtual interface name if that's not what you saw earlier. This displays a data table for all Wi-Fi routers in range. Find the router you want to hack. At the end of each string of text, you'll see a router name. These pieces of information are to the left of the network's name. Monitor the network for a handshake. A "handshake" occurs when an item connects to a network e.

You need to wait until a handshake occurs so you capture the data necessary to crack the password. As long as this command stays running, you'll be monitoring for all connections and new handshakes. Part 2. Understand what a deauth attack does. A deauth attack sends deauthentication packets to the router you're trying to break into, causing uses to disconnect and requiring them to log back in.

When a user logs back in, you will be provided with a handshake. If you don't do a deauth attack, you might have to wait around for a long time for a handshake to complete—you'll need that handshake to crack the password. If you already see a line with the tag "WPA handshake:" followed by a MAC address in the output of the airodump-ng command, skip to Step 5—you have what you need to crack the password and don't need to send deauth packets.

Remember—use these tools for ethical purposes only. Wait for something to connect to the network. To force them into a handshake, you'll now send them deauth packets that kill their connection. Open a new terminal. Make sure airodump-ng is still running in original terminal window, and drag it to another place on your desktop so both terminals are visible. Send the deauth packets.

This command will send 2 deauth packets to disconnect the client from the network. As long as you're close enough to the target client, they'll be disconnected from the router and forced to reconnect with a handshake. If this doesn't work, move closer to the client. As soon as the client reconnects, all of the information you'll need to crack the password will be available.

User Tools Log In. Site Tools Search. Step 1 - Start the wireless interface in monitor mode. Step 2 - Start airodump-ng to collect authentication handshake. Step 3 - Use aireplay-ng to deauthenticate the wireless client.

Step 4 - Run aircrack-ng to crack the pre-shared key. I Cannot Capture the Four-way Handshake! 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 v0. If you use a different version then some of the command options may have to be changed. 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.

To determine the driver and the correct procedure to follow , run the following command: airmon-ng On a machine with a Ralink, an Atheros and a Broadcom wireless card installed, the system responds: Interface Chipset Driver rausb0 Ralink RT73 rt73 wlan0 Broadcom b43 - [phy0] wifi0 Atheros madwifi-ng ath0 Atheros madwifi-ng VAP parent: wifi0 The presence of a [phy0] tag at the end of the driver name is an indicator for mac, so the Broadcom card is using a mac driver.

It should look similar to this: lo no wireless extensions. The system will respond: lo no wireless extensions. Instead, use the following command to set up your card in monitor mode on channel 9: airmon-ng start wlan0 9 The system responds: Interface Chipset Driver wlan0 Broadcom b43 - [phy0] monitor mode enabled on mon0 Notice that airmon-ng enabled monitor-mode on mon0.

The following output should appear: lo no wireless extensions. For other ieeebased drivers, simply run the following command to enable monitor mode replace rausb0 with your interface name : airmon-ng start rausb0 9 The system responds: Interface Chipset Driver rausb0 Ralink rt73 monitor mode enabled At this point, the interface should be ready to use.

Enter: airodump-ng -c 9 --bssid C:7E -w psk ath0 Where: -c 9 is the channel for the wireless network. This eliminates extraneous traffic. The deauthentication packets are sent directly from your PC to the clients. So you must be physically close enough to the clients for your wireless card transmissions to reach them.

To confirm the client received the deauthentication packets, use tcpdump or similar to look for ACK packets back from the client. Open another console session and enter: aircrack-ng -w password. Remember to specify the full path if the file is not located in the same directory. Here are some troubleshooting tips to address this: Your monitor card must be in the same mode as the both the client and Access Point.

Some drivers allow you to specify the mode. For information, 1, 2, 5. Sometimes you also need to set the monitor-mode card to the same speed. Be sure that your capture card is locked to the same channel as the AP. Be sure there are no connection managers running on your system. You are physically close enough to receive both access point and wireless client packets. Conversely, if you are too close then the received packets can be corrupted and discarded. So you cannot be too close.

Make sure to use the drivers specified on the wiki. Depending on the driver, some old versions do not capture all packets. Ideally, connect and disconnect a wireless client normally to generate the handshake.

If you use the deauth technique, send the absolute minimum of packets to cause the client to reauthenticate. Normally this is a single deauth packet. Sending an excessive number of deauth packets may cause the client to fail to reconnect and thus it will not generate the four-way handshake.

As well, use directed deauths, not broadcast. Such as missing AP packets, missing client packets, etc. Except where otherwise noted, content on this wiki is licensed under the following license: CC Attribution-Noncommercial-Share Alike 4.
