A new program to hack into wi-fi signals (wireless). How many of us has a notebook or desktop PC with wireless card and this captures several Wi-Fi signals, but want to connect to one, are protected by a password, this is the solution.

CommView for WiFi is a powerful wireless network monitor and analyzer for 802.11 a/b/g/n networks. Loaded with many user-friendly features, CommView for WiFi combines performance and flexibility with an ease of use unmatched in the industry. CommView for WiFi captures every packet on the air to display important information such as the list of access points and stations, per-node and per-channel statistics, signal strength, a list of packets and network connections, protocol distribution charts, etc. By providing this information, CommView for WiFi can help you view and examine packets, pinpoint network problems, perform site surveys, and troubleshoot software and hardware.

WEP is an encryption scheme, based on the RC4 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 semirandom 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 strongencryption while a 128 bit key has 104. The IV is placed in encrypted frames header, and is transmitted in plain text.

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!
