Connection will be made using a secret 64-bit WEP key known to both devices.

In fact, it's almost faster to do this than it is to enter the WEP key for a network that you know.

A 128-bit WEP key is usually entered as a string of 26 hexadecimal characters.

With the new attack it is possible to recover a 104-bit WEP key with probability 50% using only 40,000 captured packets.

Using this method allows for the WEP key to be retrieved in less than a minute.

Weplab is designed not only to crack WEP keys but to analyze the wireless security of a network from an educational point of view.

Weplab tries to break the WEP key using several known attacks:

An attacker therefore can assume that all the keys used to encrypt packets share a single WEP key.

Initially wireless networks were secured by WEP keys.

By using a process that targets the Windows wireless stack, it is possible to obtain the WEP key from a remote client.
