WEP Hacking - The Next Generation
WEP is an encryption scheme, based on the RC-4
cipher, that is available on all 802.11a, b and g
wireless products. WEP uses a set of bits called a
key to scramble information in the data frames as
it leaves the access point or client adapter and
the scrambled message is then decrypted by the
receiver.
Both sides must have the same WEP key, which is
usually a total of 64 or 128 bits long. A
semi-random 24 bit number called an Initialization
Vector (IV), is part of the key, so a 64 bit WEP
key actually contains only 40 bits of
"strong" encryption while a 128 bit key
has 104. The IV is placed in encrypted frame's
header, and is transmitted in plain text.
Traditionally, crac*ing WEP keys has been a slow
and boring process. An attacker would have to
capture hundreds of thousands or millions of
packets?a process that could take hours or even
days, depending on the volume of traffic passing
over the wireless network. After enough packets
were captured, a WEP crac*ing program such as
Aircrac* would be used to find the WEP key.
Fast-forward to last summer, when the first of
the latest generation of WEP cracking tools
appeared. This current generation uses a
combination of statistical techniques focused on
unique IVs captured and brute-force dictionary
attacks to break 128 bit WEP keys in minutes
instead of hours. As Special Agent Bickers noted,
"It doesn't matter if you use 128 bit WEP
keys, you are vulnerable!"
Basic Directions:
1)Boot from cd
2)get the wep key
3)write it down
4)reboot into windows
5)connect using wep key.
