    Airsnort on windows is limited. You need a card that can be put into monitor
    mode under windows to capture the WEP packets. Linux drivers make this much
    easier.

    As for other tools, the package wep-tools contains a utility for brute
    forcing ASCII based WEP keys.

    These keys are generated using a simple algorithm that is unfortunately
    flawed. It essentially reduces the keylength of WEP from 64/128 down to
    around 21 bits in length. Given just a couple of encrypted data packets, an
    offline exhaustive brute-force attack can be done in about 10-15 seconds on
    such keys.

    Well, there is a possibility to do airsnort on windows. But i would
    like to use a cd distro for that, but centrino wlan is not well
    supported. Anyway, i just posted a minute ago about my own new life
    distro focused on pentesting and wireless. Difference between
    knoppix-std and mine is usability card autodetection by kismet etc etc.
    Most known attack methods etc. i just copy my other post quickly below.

    Auditor security collection released

    Just like to inform, that i have released my penetration test distro
    right now on my companys website under the gpl. The main difference
    between phlack, fire and knoppix-std is, that it is focused on
    usability. As you know remote-exploit.org was focused in the past on
    wireless stuff, so you can bet that all the wireless stuff is included.
    No hassle to configure kismet etc, just plug in the card, start the
    scanner and go. But don't missunderstand, it is not focused on
    wireless, check the short description below or go to my companys
    website to see details and download links.

    Short description:

    The Swiss Army Knife for security assessments. A Linux-based, unified
    platform focused on penetration tests. The robust power of Open-Source
    tools without the hassles of configuring hardware or installing any
    additional software. This powerful toolset is started directly from the
    CD-ROM without any local installation. Independent of system hardware,
    Auditor security collection provides the user with over 300 powerful
    analysis tools for troubleshooting and securing networks and systems.
    Delivering powerful, functional tools in a user-friendly environment
    while eliminating complex configuration was our goal when enhancing
    knoppix and designing Auditor security collection.

    No other commercial or freely available analysis platform offers an
    equivalent level of usability with automatic configuration and focus on
    penetration testing.
