WEP cracking for dummies

For those who still don't think it's a major problem to run WEP encryption on a wireless LAN, this is your final warning.  Humphrey Cheung of Tomsnetworking has released a tutorial that can essentially be summed up as "WEP cracking for dummies".  Every time I've written articles on the vulnerability of WEP, I almost always get some wise guy telling me that I'm full of it and that I'm exaggerating the ease with which WEP can be cracked.  Now that WEP cracking is child's play, it's almost become a recreational sport for script kiddies and a primary tool of choice for hackers.  Now anyone can break in to your WEP based wireless LAN with relative ease.

As I've warned earlier, any WEP based wireless LAN can be cracked in a matter of minutes.  The current set of attacks are all implemented in a simple all-in-one CD that is available for free download over the web and it employs the latest packet injection techniques and advanced statistical analysis tools to rapidly recover WEP keys.  Even 802.1x based enterprise wireless LANs that have relied on per-user per-session rotating WEP keys to mitigate the security threat are no longer safe because they too can be cracked wide open with just a little more effort.  Corporations and homes must protect themselves with a minimum of WPA TKIP encryption but preferably use WPA2 AES encryption.
