Wireless security tools – Kismet, KisMac, NetStumbler, Airsnort, Aircrack
This sniffer is a 802.11 based network security scanner, sniffer & intrusion detector. it is designed to work with any raw monitoring capable wireless card & can sniff the following traffic: 802.11b, 802.11a, 802.11g, & 802.11n. The Kismet scanner identifies networks passively collecting packets & detects standard named networks, also decloacks hidden networks. a quantity of the features the network scanner offers are:
- 802.11b, 802.11g, 802.11a, 802.11n sniffing
- modular architecture for Client/Server
- support for multi-card and channel hopping
- standard PCAP logging
- runtime WEP decoding
- hidden SSID unveiling
- XML logging to integrate with other tools
- support for Linux, OSX, BSD and Windows.

This popular stumbler for Mac OS X offers lots of of the features of its namesake Kismet, though the codebase is entirely different. Unlike console-based Kismet, KisMAC offers a GUI & was around before Kismet was ported to OS X. It also offers mapping, Pcap-format import & logging, & even some decryption & deauthentication assaults.
Netstumbler is the best known Windows instrument for locating open wireless access points (“wardriving”). they also distribute a WinCE version for PDAs & such named Ministumbler. The instrument is currently free but Windows-only & no source code is provided. It makes use of a more active approach to finding WAPs than passive sniffers such as Kismet or KisMAC.
AirSnort is a wireless LAN (WLAN) gizmo that recovers encryption keys. It was developed by the Shmoo Group and operates by passively monitoring transmissions, computing the encryption key when packets have been gathered. You may even have an interest in the similar Aircrack.
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 encrypted packets have been gathered. It can also assault 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).
