A.
The initialization vector of WEP uses a crack-able RC4 encryption algorithm. Once enough
packets are captured an XOR operation can be performed and the asymmetric keys can be
derived.

B.
The WEP key is stored in plain text and split in portions across 224 packets of random data.
Once enough packets are sniffed the IV portion of the packets can be removed leaving the plain
text key.

C.
The WEP key has a weak MD4 hashing algorithm used. A simple rainbow table can be used to
generate key possibilities due to MD4 collisions.

D.
The WEP key is stored with a very small pool of random numbers to make the cipher text. As
the random numbers are often reused it becomes easy to derive the remaining WEP key.
