So you just need to be patient to capture as much IVs as you can, as much data packets as you can, because hacking can actually get very hectic when you have to be very patient and you need to wait for things to happen. So sometimes it will happen for you in 10, IVs or 10, data packets and sometimes it can take about two lakh or three lakh IVs too.
So for me it happened in almost one lakh and 80, IVs and now what I am going to do is I am going to turn off my monitor mode so I can check if I can connect with this network or not. So you can see that we got connected to the test network with this key we found with aircrack-ng which is testpassword1.
And another thing. We only managed to do it just because we had two devices connected to the network and there was a lot of data packets, and we got to capture a lot of data packets. And then we found the IV and then aircrack did its thing.

Skip to content Now that we know that in order to crack a WEP key we need to actually sniff as many packets as we can, we need to capture a lot of packets so we can get two packets with the same IVs or same random number on them.
Okay, so one thing we need to be clear about is if we are in monitor mode or not. So I am not in monitor mode. So I am going to turn my monitor mode on. So we have monitor mode active in wlan0mon. This is the Wi-Fi we were trying to hack. So now I am going to start capturing the packets from this test network.
So we write airodump-ng, we write — bssid and I am going to copy it from here. So now what we are going to do is we are going to run aircrack-ng along with it. So let me actually show you. As I previously stated, WEP is extremely simple to crack. Just because it's easy doesn't mean it's legal, so make sure that you have permission to do this to any network you're practicing on before launching this kind of attack.
While it's very likely the attack will succeed, and it's good to know this skill, the risk that the network you are attacking is a honeypot is much higher than the average encrypted network.
WEP is fundamentally broken, so very few people will choose to use it. Another thing you should consider is that you will very likely not be the first person to crack that WEP network. Depending on the intentions of the person who got there first, the network could be doing anything from stealing credentials to providing a VPN endpoint for very bad stuff.
Because you don't know what could be going on, be very cautious about connecting to networks that could be used for nefarious purposes. If WEP is implemented in a business, cracking WEP is often the first line of attack for a pentester to quickly embarrass their client. To crack a WEP network, you'll need to be able to stimulate enough network traffic to cryptographically attack the key.
The best way to do this is to use a wireless network adapter that's capable of packet injection. This means our adapter will be able to send forged packets to our target network, allowing us to replay anything that would cause the router to provide the amount of traffic we need.
We have a list of the best compatible network adapters available for Kali in the article linked below if you need some help selecting one.
You'll also need a fully updated version of Kali Linux, which you can run as a virtual machine or directly on something like a Raspberry Pi.
To start attacking a WEP network, you'll need to find one first. To do so, you'll run a series of filters with Airodump-ng to help you locate only vulnerable networks nearby. Airodump-ng is included in the Aircrack-ng package, so be sure to install it with apt-get install aircrack-ng if you don't already.
To get started, type ifconfig to find the name of your wireless network adapter, which you should have plugged in already. In Kali Linux, it should be something like wlan0. Next, you'll need to put your attack card into monitor mode.
In a terminal window, type sudo airmon-ng start wlan0. This will put your card into monitor mode, likely changing the name of the card as well. Take note of this new name by running ifconfig or ip a again, as you'll need it for the next step. The complete command can be seen below. This will scan the area for any packets using WEP encryption, returning the name and information of the network if one exists. Once you have the information, you'll need to use it as a filter to tailor your attack in the next step.
Once you have the information you need for targeting the WEP network from Airodump-ng, there are a few variables you'll need to remember. The next tool you're going to use is a little aggressive, to say the least. A wireless network is a network that uses radio waves to link computers and other devices together. The implementation is done at the Layer 1 physical layer of the OSI model.
You will need a wireless network enabled device such as a laptop, tablet, smartphones, etc. You will also need to be within the transmission radius of a wireless network access point. Most devices if the wireless network option is turned on will provide you with a list of available networks. If the network is not password protected, then you just have to click on connect. If it is password protected, then you will need the password to gain access.
Since the network is easily accessible to everyone with a wireless network enabled device, most networks are password protected.
It was developed for IEEE Its goal was to provide the privacy equivalent to that provided by wired networks. WEP works by encrypting the data been transmitted over the network to keep it safe from eavesdropping. Open System Authentication OSA — this methods grants access to station authentication requested based on the configured access policy.
The station encrypts the challenge with its key then responds. If the encrypted challenge matches the AP value, then access is granted. It is used to encrypt data on It uses temporal keys to encrypt packets. Cracking is the process of exploiting security weaknesses in wireless networks and gaining unauthorized access.
