The moral of the story with WEP is simply that it should never be used when stronger authentication and encryption mechanisms are available.Ĭracking WPA/WPA2-Personal (which uses a passphrase) is a much more difficult task than cracking WEP, but it still isn't an overwhelming task. With users being added to the WLAN every day in most enterprises and the amount of data going over the WLAN growing exponentially, capturing enough data to crack WEP is often simple. The length of the WEP key, 40- or 104-bit, is practically irrelevant, and with the software tools currently available, any novice can crack WEP in minutes given enough captured data. See how its done and see how to secure against it.Ĭracking WEP is fast and easy with commonly available Windows- or Linux-based tools. Ĭracking WEP is old-hat, but the newer WPA/WPA2-Personal can be cracked too. Videos are available by registering here.
