The Final Nail in WEP's Coffin
The 802.11 encryption standard Wired Equivalent Privacy (WEP) is still widely used today despite the numerous discussions on its insecurity. In this paper, we present a novel vulnerability which allows an attacker to send arbitrary data on a WEP network after having eavesdropped a single data packet. Furthermore, we present techniques for real-time decryption of data packets, which may be used under common circumstances.

WEP Cloaking for Legacy Encryption Protection
Wired Equivalent Privacy also known as WEP is the encryption protocol defined in the original IEEE 802.11 standard for Wireless Local Area Networks. Several known vulnerabilities and attack tools have compromised WEP, making it unsuitable for secure WLAN implementations without additional layers of security. Motorola’s WEP Cloaking solution is designed to make WEP virtually invulnerable to known attacks and tools, making existing WEP deployments much stronger than they otherwise would be.

Crack WEP for Beginners Setting Up The Drivers3 min. 50 sec.
A video showing people how to crack a WEP network using PTW attack. This is a step by step tutorial for beginners. It uses aircrack-ng rather than commview for wifi which is more designed for WEP cracking (still need commview for wifi drivers though)

Breaking 104 bit WEP in less than 60 seconds
Wired Equivalent Privacy (WEP) is a protocol for encrypting wirelessly transmitted packets on IEEE 802.11 networks. In a WEP protected network, all packets are encrypted using the stream cipher RC4 under a common key, the root key1 Rk. The root key is shared by all radio stations. A successful recovery of this key gives an attacker full access to the network. Although known to be insecure and superseded by Wi-Fi Protected Access (WPA), this protocol is still is in widespread use almost 6 years after practical key recovery attacks were found against it. In this paper we present a new key-recovery attack against WEP that outperforms previous methods by at least an order of magnitude.

Cracking WEP Using Backtrack: A Beginners Guide
This tutorial is intended for user's with little or no experience with linux or wifi. The folks over at remote-exploit have released "Backtrack" a tool which makes it ridiculously easy to access any network secured by WEP encryption. This tutorial aims to guide you through the process of using it effectively.

Cracking WEP with Ubuntu
This post should enable anyone to get Linux up and running and crack a WEP key. It took me about 2 days and myriad tutorials to finally get this to work, and now that I have I feel that I should share it with everyone. I am by no means a Linux expert, but this works regardless. All you need is a old laptop with a wireless card and a copy of Ubuntu Linux, currently one of the most popular and easily installed distributions of linux.

How Secure is WEP, Anyway?
My intent here is to summarize what's going on that affects WLAN security. I completely agree with the devil's advocate side to this: let's see just how easy or hard it is to crack, and see what we see even if we do crack the WEP key and decode packets. Some of the tools are slow and primitive. So there may be theoretical exposure, but perhaps it is too time-consuming or knowledge-intense for someone to actually want to use the tools.

Practical Exploitation of RC4 Weaknesses in WEP Environments
This document is provided as a conceptual supplement to dweputils, a wep auditing toolset, which is part of the bsd-airtools package provided by Dachb0den Labs. The basic goal of the article is to provide technical details on how to effectively implement the FMS attack so that it works efficiently with both a small amount of iv collection time as well as cracking and processing time and to provide details on how other pseudo random generation algorithm (prga) output bytes reveal key information.

Cracking WEP
This article deals with this issue, and explains just what cracking WEP means. I will show you just how hackers will attack you and take advantage of this weakness to capture your secret key right out of the air, which they can then use to connect to your secure wireless network.
