Top 5 Wirless Tools

  
   Kismet is an 802.11 layer2 wireless network detector, sniffer, and intrusion detection system. Kismet will work with any wireless card which supports raw monitoring (rfmon) mode, and (with appropriate hardware) can sniff 802.11b, 802.11a, 802.11g, and 802.11n traffic. Kismet also supports plugins which allow sniffing other media such as DECT. 

    Kismet identifies networks by passively collecting packets and detecting standard named networks, detecting (and given time, decloaking) hidden networks, and infering the presence of nonbeaconing networks via data traffic. 

It can automatically detect network IP blocks by sniffing TCP, UDP, ARP, and DHCP packets, log traffic in Wireshark/TCPDump compatible format, and even plot detected networks and estimated ranges on downloaded maps. As you might expect, this tool is commonly used for wardriving. Oh, and also warwalking, warflying, and warskating, ...Features-
802.11b, 802.11g, 802.11a, 802.11n sniffing
Standard PCAP file logging (Wireshark, Tcpdump, etc)
Client/Server modular architecture
Multi-card and channel hopping support
Runtime WEP decoding
Tun/Tap virtual network interface drivers for realtime export of packets
Hidden SSID decloaking
Distributed remote sniffing with Kismet drones
XML logging for integration with other tools
Linux, OSX, Windows, and BSD support (devices and drivers permitting)

It identifies networks by passively sniffing (as opposed to more active tools such as NetStumbler), and can even decloak hidden (non-beaconing) networks if they are in use.    download link

Network stumbler-

Free Windows 802.11 Sniffer

NetStumbler is a tool for Windows that allows you to detect Wireless Local Area Networks (WLANs) using 802.11b, 802.11a and 802.11g. It has many uses:

• Verify that your network is set up the way you intended.


• Find locations with poor coverage in your WLAN.


• Detect other networks that may be causing interference on your network.


• Detect unauthorized "rogue" access points in your workplace.


• Help aim directional antennas for long-haul WLAN links.


• Use it recreationally for WarDriving.

Netstumbler is the best known Windows tool for finding open wireless access points ("wardriving"). They also distribute a WinCE version for PDAs and such named Ministumbler. The tool is currently free but Windows-only and no source code is provided. It uses a more active approach to finding WAPs than passive sniffers such asKismet or KisMAC.

Requirements

General Requirements

The requirements for NetStumbler are somewhat complex and depend on hardware, firmware versions, driver versions and operating system. The best way to see if it works on your system is to try it.
Some configurations have been extensively tested and are known to work. These are detailed at http://www.stumbler.net/compat. If your configuration works but is not listed, or is listed but does not work, please follow the instructions on the web site.
The following are rules of thumb that you can follow in case you cannot reach the web site for some reason.

• This version of NetStumbler requires Windows 2000, Windows XP, or better.


• The Proxim models 8410-WD and 8420-WD are known to work. The 8410-WD has also been sold as the Dell TrueMobile 1150, Compaq WL110, Avaya Wireless 802.11b PC Card, and others.


• Most cards based on the Intersil Prism/Prism2 chip set also work.


• Most 802.11b, 802.11a and 802.11g wireless LAN adapters should work on Windows XP. Some may work on Windows 2000 too. Many of them report inaccurate Signal strength, and if using the "NDIS 5.1" card access method then Noise level will not be reported. This includes cards based on Atheros, Atmel, Broadcom, Cisco and Centrino chip sets.


• I cannot help you figure out what chip set is in any given card.

Firmware Requirements

If you have an old WaveLAN/IEEE card then please note that the WaveLAN firmware (version 4.X and below) does not work with NetStumbler. If your card has this version, you are advised to upgrade to the latest version available from Proxim's web site. This will also ensure compatibility with the 802.11b standard.

Aircrack-

The fastest available WEP/WPA cracking tool

Aircrack-ng is an 802.11 WEP and WPA-PSK keys cracking program that can recover keys once enough data packets have been captured. It implements the standard FMS attack along with some optimizations like KoreK attacks, as well as the all-new PTW attack, thus making the attack much faster compared to other WEP cracking tools.In fact, Aircrack-ng is a set of tools for auditing wireless networks.Aircrack is a suite of tools for 802.11a/b/g WEP and WPA cracking. It can recover a 40 through 512-bit WEP key once enough encrypted packets have been gathered. It can also attack WPA 1 or 2 networks using advanced cryptographic methods or by brute force. The suite includes airodump (an 802.11 packet capture program), aireplay (an 802.11 packet injection program), aircrack (static WEP and WPA-PSK cracking), and airdecap (decrypts WEP/WPA capture files) information & download link

Airsnort-
802.11 WEP Encryption Cracking Tool
AirSnort is a wireless LAN (WLAN) tool which recovers encryption keys. AirSnort operates by passively monitoring transmissions, computing the encryption key when enough packets have been gathered.802.11b, using the Wired Equivalent Protocol (WEP), is crippled with numerous security flaws. Most damning of these is the weakness described in " Weaknesses in the Key Scheduling Algorithm of RC4 " by Scott Fluhrer, Itsik Mantin and Adi Shamir. Adam Stubblefield was the first to implement this attack, but he has not made his software public. AirSnort, along with WEPCrack, which was released about the same time as AirSnort, are the first publicly available implementaions of this attack.
AirSnort requires approximately 5-10 million encrypted packets to be gathered. Once enough packets have been gathered, AirSnort can guess the encryption password in under a second.AirSnort is a wireless LAN (WLAN) tool that recovers encryption keys.  download link
KisMAC- A GUI passive wireless stumbler for Mac OS X
is an open-source and free WiFi stumbler/scanner application for Mac OS X. It has an advantage over MacStumbler/iStumbler/NetStumbler in that it uses monitor mode and passive scanning.
KisMAC supports several third party USB cards - USB Prism2, and USB Ralink support. All of the internal AirPort Extreme hardware is supported as well.This popular stumbler for Mac OS X offers many of the features of its namesake Kismet, though the codebase is entirely different. Unlike console-based Kismet, KisMAC offers a pretty GUI and was around before Kismet was ported to OS X. It also offers mapping, Pcap-format import and logging, and even some decryption and deauthentication attacks.
