For example, Airgeddon requires Aircrack-ng to run. By configuring and executing these scripts for the user, Airgeddon can make Wi-Fi cracking easier to perform. Many Wi-Fi networks use secure encryption protocols, making them more difficult to attack.
Tools like Wifiphisher attempt to steal user credentials via phishing attacks. After gaining access to a wireless network, a penetration tester needs to perform network sniffing and traffic analysis to take advantage of that visibility. A couple of different options exist for monitoring and dissecting the traffic flowing over wireless networks. Wireshark is the most popular network traffic analysis tool in existence.
Its wide array of built-in protocol decoders make it easy to dissect and examine packets from all types of network traffic. Wireshark can be run on packet capture files or perform live traffic capture, including wireless traffic.
Wireshark is designed to be an intuitive and easy-to-use tool, but it is designed for network traffic analysis. This means that, while the tool may be easy to use and invaluable for wireless hacking, an understanding of network fundamentals is necessary to use it effectively.
OmniPeek is a commercial network packet analyzer designed for the Windows platform. It offers a variety of visualizations and graphs to help in understanding the traffic present on the network. While it still requires an understanding of network protocols to use effectively, it provides an alternative to Wireshark for network analysis. Packet injection enables a penetration tester to inject data into an established network connection. This helps perfrom denial of service DoS and man-in-the-middle MitM attacks against wireless network users.
Airjack is a packet injection tool for Wi-Fi In some scenarios, performing wireless network hacking on a laptop would be conspicuous, while a mobile device would be essentially invisible.
A few different platforms exist for performing penetration testing against wireless networks from a mobile device. It provides several different tools for Wi-Fi hacking and mobile penetration testing, including Wireless Among its many features are Wi-Fi hacking scripts designed to perform MitM and other automated attacks against the network.
Wireless network hacking is an essential skill set for the modern penetration tester. While the tools described in this post are organized into categories, many have functionality that spans multiple different areas.
Gaining familiarity with a few different wireless hacking tools can be a valuable investment in an ethical hacking career. A new tab for your requested boot camp pricing will open in 5 seconds.

The print screen below shows you what you want to see in your iwconfig screen. Use the injection test to confirm your card can inject prior to proceeding.
Try executing the following two commands in your terminal window:. They both should result in the " Injection is working! Ok, we have all the hardware and software ready, now it is time to explain how WEP cracking works. If you want to listen to network traffic and to capture network traffic, your network adapter needs to be in Monitor mode. If you want to crack WEP, you need to know a little more than just the network name. You also need to know the MAC address of the wireless access point or wireless router which you can find by executing the following command:.
You can see names of available wireless networks in the most right column and MAC addresses of access points in the most left column. You can also find out on which channel each access point operates. In order to take advantage of the packet injection technique, you need to be associated with the target wireless access point. If that is the case with your target network, you need to first discover a MAC address of an already associated user and then use that MAC address for your own authentication and association.
Read the following two pages:. Note, you will need to disable your network adapter before changing your MAC address and then enable it again, so it is an exercise that goes through the two pages referenced above as well as through point 1 and 2 again.
Remember, you need to find a client on the network that is already associated with your target access point. You can do so by executing the following command in your Ubuntu terminal window:. By now, you should have all the needed information about your target access point name, MAC, channel, etc. Now you want to start capturing all the new unique so-called Initialization Vectors IVs included in packets that go out of your access point.
Open new terminal window and do:. This is the same command as in step 3. We used it in step 3 to find someone that is already using your wireless access point; now we use it to capture initialization vectors. The option -w wepdump is the name of file where you want to save your initialization vectors.
Option -i means that you want to save initialization vectors only and discard all other data. Now it is time to sort of "login" into your wireless network. In order for an access point to accept a packet, the source MAC address must already be associated. If the source MAC address you are injecting later is not associated with the access point then the access point ignores the packet and sends out a " DeAuthentication " packet in cleartext. In this state, no new initialization vectors are created because the access point is ignoring all the injected packets.
The lack of association with the access point is the single biggest reason why packet injection fails. At this point you are just connecting to the access point and telling it you are here and want to talk to it. This does not give you any ability to transfer data. Open another terminal window and do:.
Remember, the MAC address you target for injection must be associated with the access point by either using fake authentication or using a MAC address from an already-associated client step 3 , or both at best.
Possible problem: If you get " Got a deauthentication packet " and then continuous retries, then you are probably dealing with MAC filtering that is some access points are configured to only allow selected MAC addresses to associate and connect.
Go back to step 3. If this is the case, you will not be able to successfully do fake authentication unless you know one of the MAC addresses on the allowed list. Get closer to the access point. Sending Authentication Request [ACK] that just keeps repeating on the aireplay-ng screen is another common problem. If you keep getting " Sending Authentication Request " or " Sending Association Request " that keep coming back, then you are too far away from the access point or are dealing with weak signal.
Remember, the fact that you can capture packets from the access point does not mean that the access point can also capture packets from your computer.
