With the popularity of wireless networks and mobile computing, an overall understanding of common security issues has become not only relevant, but very necessary for both home/SOHO users and IT professionals alike. This article is aimed at illustrating current security flaws in WEP/WPA/WPA2. Successfully cracking a wireless network assumes some basic familiarity with networking principles and terminology, as well as working with command- line tools. A basic familiarity with Linux can be helpful as well. Disclaimer: Attempting to access a network other than your own, or one you have permission to use is illegal insome U. S. jurisdictions. Speed Guide, Inc. To successfully crack WEP/WPA, you first need to be able to set your wireless network card in "monitor" mode to passively capture packets without being associated with a network. This NIC mode is driver- dependent, and only a relatively small number of network cards support this mode under Windows. One of the best free utilities for monitoring wireless traffic and cracking WEP/WPA- PSK keys is the aircrack- ng suite, which we will use throughout this article. It has both Linux and Windows versions (provided your network card is supported under Windows). The aircrack- ng site has a comprehensive list of supported network cards available here: NIC chipset compatability list. If your network card is not supported under Windows, one can use a free Linux Live CD to boot the system. Back. Track is probably the most commonly used distribution, since it runs from a Live CD, and has aircrack- ng and a number of related security auduting tools already installed. For this article, I am using aircrack- ng on another Linux distro (Fedora Core) on a Sony Vaio SZ- 6. Intel 4. 96. 5agn network card. If you're using the Back. Track CD aircrack- ng is already installed, with my version of linux it was as simple as finding it with: yum search aircrack- ngyum install aircrack- ng. The aircrack- ng suite is a collection of command- line programs aimed at WEP and WPA- PSK key cracking. The ones we will be using are: airmon- ng - script used for switching the wireless network card to monitor modeairodump- ng - for WLAN monitoring and capturing network packetsaireplay- ng - used to generate additional traffic on the wireless networkaircrack- ng - used to recover the WEP key, or launch a dictionary attack on WPA- PSK using the captured data. Setup (airmon- ng)As mentioned above, to capture network traffic wihtout being associated with an access point, we need to set the wireless network card in monitor mode. To do that under linux, in a terminal window (logged in as root), type: iwconfig (to find all wireless network interfaces and their status)airmon- ng start wlan. Note: You can use the su command to switch to a root account. Other related Linux commands: ifconfig (to list available network interfaces, my network card is listed as wlan. MAC address of a NIC - can even simulate the MAC of an associated client. NIC should be stopped before chaning MAC address)iwconfig wlan. Recon Stage (airodump- ng)This step assumes you've already set your wireless network interface in monitor mode. It can be checked by executing the iwconfig command. Next step is finding available wireless networks, and choosing your target: airodump- ng mon. It is best to select a target network with strong signal (PWR column), more traffic (Beacons/Data columns) and associated clients (listed below all access points). Once you've selected a target, note its Channel and BSSID (MAC address). Also note any STATION associated with the same BSSID (client MAC addresses). WEP is much easier to crack than WPA- PSK, as it only requires data capturing (between 2. WPA- PSK needs a dictionary attack on a captured handshake between the access point and an associated client which may or may not work. Capture Data (airodump- ng)To capture data into a file, we use the airodump- ng tool again, with some additional switches to target a specific AP and channel. Most importantly, you should restrict monitoring to a single channel to speed up data collection, otherwise the wireless card has to alternate between all channels. Assuming our wireless card is mon. F: CC: 7. D: 5. A: 7. F: CC: 7. D: 5. A: 7. MAC address of our target access point, - w data specifies that we want to save captured packets into a file called "data" in the current directory, mon. Notes: You typically need between 2. WEP key. One can also use the "- -ivs" switch with the airodump- ng command to capture only IVs, instead of whole packets, reducing the required disk space. However, this switch can only be used if targeting a WEP network, and renders some types of attacks useless. Increase Traffic (aireplay- ng) - optional step for WEP cracking. An active network can usually be penetrated within a few minutes. However, slow networks can take hours, even days to collect enough data for recovering the WEP key. This optional step allows a compatible network interface to inject/generate packets to increase traffic on the wireless network, therefore greatly reducing the time required for capturing data. The aireplay- ng command should be executed in a separate terminal window, concurrent to airodump- ng. It requires a compatible network card and driver that allows for injection mode. Assuming your network card is capable of injecting packets, in a separate terminal window try: aireplay- ng - 3 - b 0. F: CC: 7. D: 5. A: 7. A5: 2. F: A7: DE - x 5. ARP- request replay- b ... MAC address of access point- h ... MAC address of associated client from airodump- x 5. Notes: To test whether your nic is able to inject packets, you may want to try: aireplay- ng - 9 wlan. You may also want to read the information available - here- . To see all available replay attacks, type just: aireplay- ng. Crack WEP (aircrack- ng)WEP cracking is a simple process, only requiring collection of enough data to then extract the key and connect to the network. You can crack the WEP key while capturing data. In fact, aircrack- ng will re- attempt cracking the key after every 5. To attempt recovering the WEP key, in a new terminal window, type: aircrack- ng data*. Notes: If your data file contains ivs/packets from different access points, you may be presented with a list to choose which one to recover. Usually, between 2. WEP key. It may sometimes work with as few as 1. Crack WPA or WPA2 PSK (aircrack- ng)WPA, unlike WEP rotates the network key on a per- packet basis, rendering the WEP method of penetration useless. Cracking a WPA- PSK/WPA2- PSK key requires a dictionary attack on a handshake between an access point and a client. What this means is, you need to wait until a wireless client associates with the network (or deassociate an already connected client so they automatically reconnect). All that needs to be captured is the initial "four- way- handshake" association between the access point and a client. Essentially, the weakness of WPA- PSK comes down to the passphrase. A short/weak passphrase makes it vulnerable to dictionary attacks. To successfully crack a WPA- PSK network, you first need a capture file containing handshake data. This can be obtained using the same technique as with WEP in step 3 above, using airodump- ng. You may also try to deauthenticate an associated client to speed up this process of capturing a handshake, using: aireplay- ng - -deauth 3 - a MAC_AP - c MAC_Client mon. MAC_IP is the MAC address of the access point, MAC_Client is the MAC address of an associated client, mon. NIC). The command output looks something like: 1. Waiting for beakon frame (BSSID: 0. Sending 6. 4 directed De. Auth. STMAC: [0. 0: 1. ACKs]Note the last two numbers in brackets [ 5: 6. ACKs] show the number of acknowledgements received from the client NIC (first number) and the AP (second number). It is important to have some number greater than zero in both. If the first number is zero, that indicates that you're too far from the associated client to be able to send deauth packets to it, you may want to try adding a reflector to your antenna (even a simple manilla folder with aluminum foil stapled to it works as a reflector to increase range and concentrate the signal significantly), or use a larger antenna. Once you have captured a four- way handshake, you also need a large/relevant dictinary file (commonly known as wordlists) with common passphrases. See related links below for some wordlist links. You can, then execute the following command in a linux terminal window (assuming both the dictionary file and captured data file are in the same directory): aircrack- ng - w wordlist capture_file (where wordlist is your dictionary file, and capture_file is a . WPA handshake)Additional Notes: Cracking WPA- PSK and WPA2- PSK only needs 4 packets of data from the network (a handshake). After that, an offline dictionary attack on that handshake takes much longer, and will only succeed with weak passphrases and good dictionary files. A good size wordlist should be 2. Megabytes in size, cracking a strong passphrase will take hours and is CPU intensive. Cracking WPA/WPA2 usually takes many hours, testing tens of millions of possible keys for the chance to stumble on a combination of common numerals or dictionary words. Still, a weak/short/common/human- readable passphrase can be broken within a few minutes using an offline dictionary attack. My record time was less than a minute on an all- caps 1. A modern laptop can process over 1. Million possible keys in less than 3 hours. WPA hashes the network key using the wireless access point's SSID as salt. This prevents the statistical key- grabbing techniques that broke WEP, and makes hash precomputation more dificult because the specific SSID needs to be added as salt for the hash.
