Tools and utilities to help you test, monitor and protect your wireless network

NetStumbler
NetStumbler displays wireless access points, SSIDs, channels, whether WEP encryption is enabled and signal strength. NetStumbler can connect with GPS technology to accurately log the precise location of access points.

MiniStumbler
A smaller version of NetStumbler designed to work on PocketPC 3.0 and PocketPC 2002 platforms. It provides support for ARM, MIPS and SH3 CPU types.

WEPCrack
WEPCrack was the first of the WEP encryption cracking utilities. WEPCrack is an open-source tool used to break 802.11 WEP keys. You can also download WEPCrack for Linux.

Airsnort
Airsnort is a wireless LAN (WLAN) tool which cracks WEP encryption keys. AirSnort passively monitors wireless transmissions and automatically computes the encryption key when enough packets have been gathered.

BTScanner
Btscanner allows you to extract as much information as possible from a Bluetooth device without the requirement to pair. It extracts HCI and SDP information, and maintains an open connection to monitor the RSSI and link quality.

FakeAP
The polar opposite of hiding your network by disabling SSID broadcasts- Black Alchemy's Fake AP generates thousands of counterfeit 802.11b access points. As part of a honeypot or as an instrument of your site security plan, Fake AP confuses Wardrivers, NetStumblers, Script Kiddies, and other scanners.

Kismet
Kismet is an 802.11 wireless network detector, sniffer, and intrusion detection system. Kismet identifies networks by passively collecting packets and detecting standard named networks, detecting (and given time, decloaking) hidden networks, and inferring the presence of nonbeaconing networks via data traffic.

Redfang
Redfang v2.5 is an enhanced version from @Stake of the original Redfang application that finds non-discoverable Bluetooth devices by brute-forcing the last six bytes of the device's Bluetooth address and doing a read_remote_name().

SSID Sniff
A tool to use when looking to discover access points and save captured traffic. Comes with a configured script and supports Cisco Aironet and random prism2 based cards.

WiFi Scanner
WifiScanner analyzes traffic and detects 802.11b stations and access points. It can listen alternatively on all 14 channels, write packet information in real time, search access points and associated client stations. All network traffic may be saved in the libpcap format for post analysis.

wIDS
wIDS is a wireless IDS. It detects the jamming of management frames and could be used as a wireless honeypot. Data frames can also be decrypted on the fly and re-injected onto another device.

WIDZ
WIDZ is a proof of concept IDS system for 802.11 wireless networks. It guards access points (AP's) and monitors local frequencies for malicious activity. It detects scans, association floods, and bogus/Rogue AP's. It can also be integrated with SNORT or RealSecure.
