How to Break WEP Encryption (with Pictures)1. Use Linux. Windows cannot sniff WEP packets, but you can use a bootable CD of Linux.
Backtrack is a commonly- used option. Download the iso image and burn it on a bootable CD/DVD. Use your bootable CD/DVDs. That means whenever you shutdown the Backtrack, all your data will be lost.
Select a start- up option. The following Backtrack screen will show after booting.
Change the option with the up and down arrow keys and select one. This tutorial will use the first option. In this option, Backtrack is started on command base. Type command: startx to continue. It'll be the fifth option.
Enter the following command: . You should see something like wlan. Interface. Enter the following command: . You should get three things. BSSIDChannel. ESSID (AP Name)Here's what the tutorial case turned up. BSSID 0. 0: 1. 7: 3.
F: 7. 6: 3. 6: 6. EChannel number 1. ESSID(AP Name)Suleman. Enter the following command. This one will use the example information above, but you should plug in your own.

Type the following command, substituting the values for your own BSSID, Channel and ESSID. Type the following command: . It will take 1. 5 to 6. Type the following command: . This will show the directories saved on it during decrypting. For the example, it would be the following: . The setup shown below will start.
After this setup completes, you'll be able to break the key. In this example, it was .
It works with any wireless network interface controller whose driver supports raw monitoring mode and can sniff 8. The program runs under Linux, Free. BSD, OS X, Open. BSD, and Windows; the Linux version is packaged for Open. Wrt and has also been ported to the Android, Zaurus PDA and Maemo platforms; and a proof of concept port has been made to the i.
Phone. In April 2. Darmstadt University of Technology in Germany developed a new attack method based on a paper released on the RC4 cipher by Adi Shamir. This new attack, named 'PTW', decreases the number of initialization vectors or IVs needed to decrypt a WEP key and has been included in the aircrack- ng suite since the 0. Aircrack- ng is a fork of the original Aircrack project.
Features. Aircrack- ng - Official Aircrack- ng blog (Blog).
There is a lot of luck involved and sometimes you may break the WEP encryption after gathering just 2. IVs, but most times it takes more than 1. A 1. 28 bit key can be broken with around 1. IVs. When we reconfigured our target AP with a 1.
WEP key with 2. 00,0. IVs, but it took the laptop we used more than an hour. Having more captured IV's would have sped up the process dramatically - .
Wireless Cracking Tools. Most serious hackers and network auditors use the open- source operating system Linux as the platform from which they launch attacks and perform analysis.
This section highlights some of the more popular tools, mostly Linux, that can be used to search out and hack wireless networks. Air. Snort. The home page for the free cracking application, Air. Snort, plainly states, . In even more simplistic terms, Air.
Snort is a program that listens to the wireless radio transmissions of a network and gathers them into a meaningful manner. After enough time has passed (sometimes in a matter of hours) and data are gathered, analytical tools process the data until the network security is broken. At that point everything that crosses the network can be read in plain text. The authors of this fully functional encryption- cracking tool have maintained from the first days of release it would expose the true threats of WEP encryption. Jeremy Bruestle, one of two lead programmers for the project, has truly recognized the inherent dangers of WEP. He states during an interview in 2. It is not obvious to the layman or the average administrator how vulnerable 8.
It's too easy to trust WEP.” Air. Snort is not the only open- source tool used for wireless cracking but the first publicly recognized freeware to put the power of an intellectually skilled- criminal into the hands of a neighbor, who just got the cheapest deal from the local ISP. WEPcrack. WEPcrack, simultaneously being developed along with Air.
Snort, is another wireless network cracking tool. It too exploits the vulnerabilities in the RC4 Algorithm, which comprise the WEP security parameters. While WEPcrack is a complete cracking tool, it is actually comprised of three different hacking applications all of which are based on the development language of PERL.
The first, Weak. IVGen, allows a user to emulate the encryption output of 8. Prism- get. IV is the second application that will analyze packets of information until ultimately matching patterns to the one known to decrypt the secret key. Thirdly the WEPcrack application pulls the two other beneficial data outputs together to decipher the network encryption. Kismet. Kismet is an extremely useful tool that supports more of an intrusion detection approach to the wireless security.
However, Kismet can be used to detect and analyze access points within range of the computer on which it is installed. Among many other things, the software will report the SSID of the access point, whether or not it is using WEP, which channels are being used, and the range of IP addresses employed.
Other useful features of Kismet include de- cloaking of hidden wireless networks, and graphical mapping of networks using GPS integration. Ethereal. Ethereal is a pre- production network capturing utility. Currently capable of identifying and analyzing 5. Ethereal can pose a substantial threat through the discovery and detection of any network communication. One of many network analyzers, this application arguably does the most comprehensive job of seeing and recognizing everything that goes by its sensor. Download Halo 2 Trial Version. Airjack. Known as a packet injection/reception tool, Airjack is an 8.
Prism network card (mainly Linux hardware). Other names include wlan- jack, essid- jack, monkey- jack, and kracker- jack.
This tool was originally used as a development tool for wireless applications and drivers to capture, inject, or receive packets as they are transmitted. It’s a fundamental tool used in Do. S attacks and Man- in- the- Middle attacks. Its capabilities include being able to inject data packets into a network to wreck havoc on the connections between wireless node and their current access point. A common hacking use for this tool is to kick everyone off of an access point immediately, and keep them logged off for as long as you like.
Without the Layer- 1, frame level authentication on all 8. Airjack would passively assume the identity of an access point and then once inside of the channel of communication between node and AP, Airjack would begin sending dissociate or deauthenticate frames sequentially at a high rate. The users’ networks network cards interpret this as their AP and they drop their connection. Host. APHost. AP is really nothing more than a firmware for Prism cards to act as an access point in any environment. With multiple scanning, broadcasting, and management options, Host. AP can lure disconnected clients into a connection with the Host.
