Wireless Network Security Tools

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.

ApSniff

ApSniff is a wireless (802.11) access point sniffer for Windows 2000. It enables you to list all access points broadcasting beacon signals at your location. Useful for helping you set new access points making sure you do not have interfering APs, and helping you set-up wireless clients by providing you with the client configuration information. Requires WLAN cards of Prism 2 chipset. It works with a DLINK DWL-650 and linksys WPC11.

PrismStumbler

Prismstumbler is a wireless LAN (WLAN) discovery tool which scans for beacon frames from access points. Prismstumbler operates by constantly switching channels and monitors any frames received on the currently selected channel.

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

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.

WifiScanner

WifiScanner is a tool that has been designed to discover wireless node ( i.e access point and wireless clients). It is distributed under the GPL License. It work with CISCOR card and prism card with hostap driver or wlan-ng driver. An IDS system is integrated to detect anomaly like MAC usurpation.

Wellenreiter

Wellenreiter is a GTK / Perl program that makes the discovery and auditing of 802.11b wireless networks much easier. All three major wireless cards (Prism2 , Lucent, and Cisco) are supported. It has an embedded statistics engine for the common parameters provided by wireless drivers. Its scanner window can be used to discover access-points, networks, and ad-hoc cards. It detects ssid broadcasting or non-broadcasting networks in every channel. Non-broadcasting networks could be uncovered automatically. The manufacturer and WEP is automatically detected.

WepLab

WepLab is a tool designed to teach how WEP works, what different vulnerabilities has, and how they can be used in practice to break a WEP protected wireless network. So far, WepLab more than a Wep Key Cracker, is a Wep Security Analyzer designed from an educational point of view.

BTScanner

BTscanner is a tool that extracts as much information as possible from a Bluetooth device without the requirement to pair. A detailed information screen extracts HCI and SDP information, and maintains an open connection to monitor the RSSI and link quality. BTScanner is based on the BlueZ Bluetooth stack, which is included with recent Linux kernels, and the BlueZ tSolset. Using the information gathered from these sources, it is possible to make educated guesses as to the host device type.

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 hidden networks, and inferring the presence of non beaconing networks via data traffic.

Mognet

Mognet is a free, open source wireless ethernet sniffer / analyzer written in Java. It is licensed under the GNU General Public License. It was designed with handheld devices like the iPaq in mind, but will run just as well on a desktop or laptop.
