Do you want to make sure that your network is safe from intruders? You can try hacking your own network with free programs to test the strength of the encryption. Note: It is illegal to use these programs to hack someone else's network. Follow the steps in this article to test the security of your network.

To step

Method 1 of 2: Start WiFiSlax

1. Download and burn WiFiSlax. WiFiSlax is an operating system that you load from a CD. It contains the tools necessary to crack WEP encryption on wireless networks. It only works with WEP encryption, not WPA / WPA2. You can download WiFiSlax for free from the developer's website here.
   • Burn the .iso file you downloaded to a blank CD. For this you can use free (freeware) software with which you can burn an "image", or an exact copy. Open the burning software and select "Burn Image". Select the .iso file you downloaded.
2. Check your computer's hardware. To run this crack you need the IPW3945 chipset. To find out if your computer has this chipset, open a command prompt window by clicking Start and then typing CMD in the search box or "Run". In the command prompt window, type "ipconfig / all". See if you see "Intel PRO / Wireless 3945ABG Network Connection". This is a very common chipset on laptops.
   • On computers with other operating systems such as Linux you can download a program such as hardinfo to obtain a complete list of your computer's hardware.
3. Make sure your computer boots from the CD. To use WiFiSlax, the computer must boot from the CD drive. You do this by restarting the computer and opening the BIOS menu. When the manufacturer's logo appears, you can see which key to press to access BIOS. Usually it is F2, F10, F12 or Del.
   • In the BIOS screen, navigate to the Boot menu. Set the CD drive as the boot disk. Sometimes the drive is listed as "optical drive". If you set the CD drive as the boot disk, the computer will always try to boot from a CD or DVD first.
4. Start WiFiSlax. If you have adjusted the BIOS settings and restarted your computer, press any key when prompted to boot from CD. In the menu that appears, select NO PCMCIA and press Enter.
   • Log in with the following information:
     
     • User: root
     • Password: tor
   • Enter the command "startx" to start WiFiSlax with a graphical interface.

Method 2 of 2: Crack WEP

1. Start the scanning process. Click on the start menu and go to WiFiSlax> Asistencia chipset> Asistencia Intel pro wireless> Cargar ipw3945 inyección - ipwray-ng. This puts the network card in "wifi0 mode", which is the mode in which the activities are mapped.
2. Type the command "airodump-ng wifi0". With this command you display all WiFi data that the card collects when it is in "wifi0 mode".
   • Now you have to see which BSSID has the most beacons. "BSSID" is the name of the network, the number of "beacons" indicates the signal strength. The more beacons there are, the easier it is to crack it. Note which channel (CH) the network uses.
3. Open Airoway. Click Start and go to WiFiSlax> Herramientas Wireless> Airoway. Now several command prompt windows will open.
4. Select the channel. In the "Airoway Command" window, select the channel of the network you are trying to crack. Press enter to begin. Select the "access point" you want to crack by clicking on the corresponding number.
   • If you have selected an access point, a new menu will open. Select option 2 (associate a MAC address) and then option 3 (replay live ARPs). The latter option will speed up the process.
5. Wait while packets are collected. The program will now collect packets. The more packets you have, the more likely you are to be able to crack the WEP.
   • If the category "Data" in the scan window shows between 20,000 and 30,000, you can press 8 on your keyboard to crack the key.
6. Copy the key. If the attack was successful, the key will be displayed in the bottom right window. Check that the value at "Decrypted Correctly" is 100%, otherwise the key will not work.
   • The key is displayed in both hexadecimal (HEX) format and ASCII format. The ASCII key is what you normally enter when you want to connect to a network.

Tips

• It could be that WiFiSlax is not working on your computer. Sometimes additional configuration is required to activate graphics mode.
• It is difficult or even impossible to crack a network with a weak signal.
• If you enter the cracked key, use the ASCII key (the second one). You can also use the HEX key (the first), but then leave out ":".
• Sometimes the CD will crash. Then restart the operating system.
• Sometimes it takes more than 30,000 packets to successfully crack the key, sometimes even a million or more.
• Sometimes it takes an hour or more to collect packets. Please try again later, restart the computer or change the location of your computer.
• Note: with WiFiSlax you can only crack WEP, not WPA.

Warnings

• Breaking into a network without permission is illegal. This article was written with the idea of ​​being able to test the security of your own WEP encryption.

Necessities

• A computer with the IPW3945 chipset
• WiFiSlax, burned to a CD
