You can check the wireless devices available: Once you've got your WEP wireless network, open up your Kali computer. The first step is to change your router's settings so that it uses the WEP security protocol. This attack will utilize Aircrack, which comes with Kali Linux (it's one of the top 10 Kali programs!). Based on my many Kali adventures in wireless USB dongle land, I recommend Panda brand wireless USB adapters, and using the wicd network manager (do not use the built-in Gnome Network Manager!). You'll also need a working wireless network device. The steps for putting your wireless card in monitoring mode are slightly different between Kali 1 and Kali 2. You'll need three components for this attack: a target router running WEP encryption, a laptop running the attack on Kali, and a third party sheep (client) that will connect to the WEP network and make this attack possible.Īs mentioned above, for this attack you'll need a device running Kali Linux.

Since all of these packets are all encrypted, you've just tricked the router into giving you a much faster source of encrypted packets with which to crack the WEP passphrase. The router will then respond to that flood of packets with a flood of its own response packets.

By spoofing the MAC address of a device that's already connected to the network, you can confuse the router by grabbing a packet, duplicating it, and sending a flood of these duplicate packets 'from' a device on the target computer (actually sent from your computer). While the WEP encryption protocol is pretty easy to crack, it requires a lot of packets - a LOT of packets - so by itself, the first weakness isn't very useful, since it might still take days just to gather enough information to crack the passphrase.Įnter weakness number two: even if you're not on a network, you can still send packets to the router. The simplicity of the WEP security protocol is the first weakness that this attack takes advantage of. This means an attacker can listen to traffic on the network, and even though it's encrypted, still use it to determine the passphrase by brute force. With WEP 64 bit, the passphrase is a five-character key - pretty easy to crack. The less sophisticated that encryption, the less information the attacker needs. But as with any cryptosystem, the more information (wireless packets) an attacker has, the better able they are to attack the encryption. Some of these link into business systems, some are for home routers, and a few are marked as 'less secure.' (This tutorial will show you precisely why!) Each of these different security protocols is simply a way for the traffic that's being sent between the router and your computer to be encrypted, so that no one else can read it. When you configure your home router, you've got a myriad of different options for your router security protocol. 4.6.3 Window 3: Crack the WEP Passphrase.4.6.2 Window 2: Increase Network Traffic with Spoofed Packets.4.6.1 Window 1: Monitor Traffic on Network.
