WEP cracks resemble WPA cracks in a lot of ways. To be true, breaching these wireless networks basically involve the same command-line tools, networking terminologies, and hacking principles. The fact that Linux systems are basically alike (if not altogether clones of each other) is also helpful when it comes to cracking WEP. After the command line programs are deployed, the WEP and WPA encryption process can commence via the steps described below:
Configure the wireless network card
To "monitor" mode first in order to obtain the network traffic you need without linking it to any specific access points. This will allow the system to secure the packets while detaching itself from any network. The NIC driver is compatible to a few network cards too.
After connecting the network card, double-check it with the airmon-ng script (a special code that can setup the card to monitor mode as well). Choose the networks available and pick the one you want to target. The airodump-ng tool is usually utilized for packet capture and channel monitoring, so it should also be quite useful for searching through available networks.
Select the networks that attract larger traffic and associated clients as well as emit strong signals (e.g., PWR columns). List the channel of your target, the BSSID address (otherwise known as the MAC address), and any stations linked with the BSSID address.
To catch the data into a file, use the aforementioned airodump-ng tool. Insert several switches so that you can target a specific channel and AP. To speed up the data capturing process and prevent the wireless card from changing channels, you must curb monitoring into a solitary channel.
An active and speedy network is the easiest type of system to penetrate. In turn, slow and congested networks can take hours, even whole days, to breach. Ergo, you must take advantage of the aireplay-ng command alongside the airodump-ng one in separate windows to streamline the entire process. Moreover, cracking is most effective only where the driver enables injection mode.
WEP cracking requires a smooth connection to a network, the extraction of the key, and the collection of adequate data. Even while the data is just being captured, you can still do the cracking process; just make use of the aircrack-ng data*.cap found within the terminal window where the data is being seized.
