Do you want to make sure your home network is secure? You can hack your network thanks to free tools created to test the security of its encryption. Using these tools to hack into networks not owned by you is illegal. Follow this guide to test the security level of your network.
Steps
Method 1 of 2: Method 1: Run WiFiSlax
Step 1. Get and burn WiFiSlax
WiFiSlax is an operating system that runs from CD. It contains all the tools needed to crack the WEP encryption of wireless networks. WiFiSlax only works with WEP encryption, not WPA / WPA2, and is available for free from the developer's website.
Burn the.iso file you downloaded to a blank CD. You can use any free burning tool to do this. Run the burning program and select Burn Image. Select the.iso file you downloaded
Step 2. Check your computer hardware
In order to run these tools you will need the IPW3945 chipset. To find out if your computer has this chipset, open the command prompt by clicking on Start and typing CMD in the search box. At this point type "ipconfig / all" in the command prompt. Look for "Intel PRO / Wireless 3945ABG Network Connection", a common chipset on many laptops.
In other operating systems, such as Linux-based ones, you can download programs such as hardinfo to get the complete list of computer hardware components.
Step 3. Configure CD booting
In order to use WiFiSlax you need to make sure your computer is booted from the CD. To configure this feature, restart your computer and enter the BIOS. You can enter the BIOS when the manufacturer logo appears. The key to press will be displayed on the screen, typically it is one of F2, F10, F12 or Del.
On the BIOS screen, select the Boot menu. Select the CD / DVD drive as the primary boot device (it may sometimes appear under the name "optical disc"). Configuring it as the primary device will cause the computer to boot from the CD before attempting to boot the operating system normally from the hard drive
Step 4. Run WiFiSlax
After changing the BIOS settings and restarting the computer, press a key when asked if you want to boot from the CD. In the first menu that will appear, select No PCMCIA and press Enter.
- Log in with your credentials:
- User: root
- Password: toor
- Type the "startx" command to run WiFiSlax with a graphical interface.
Method 2 of 2: Method 2: Crack the WEP
Step 1. Launch the scan process
Click on the Start menu and select WiFiSlax> Asistencia chipset> Asistencia Intel pro wireless> Cargar ipw3945 inyección - ipwray-ng to set the network card in wifi0 mode (monitoring mode).
Step 2. Enter the command "airodump-ng wifi0"
All data collected by your network card in monitoring mode will appear on the screen.
Note the BSSID with the most bars. The BSSID is the name of the network, while the number of bars represents the signal strength. The greater the number of bars, the easier it will be to crack the net. Also note the channel (CH) occupied by the network
Step 3. Run Airoway
Click on Start and select WiFiSlax> Herramientas Wireless> Airoway. Various command line windows will be displayed.
Step 4. Select the channel
In the Airoway Command window, select the BSSID channel you want to crack. Press Enter to begin the process. Select the access point you want to crack by pressing its number.
Once the access point is selected, a new menu will appear. Select option number 2 to associate a MAC address and then option number 3 to send ARP packets (speeding up the process)
Step 5. Wait for the packets to accumulate
Once the process has begun, you will have to wait a few moments for the program to collect the packets. The more packages you collect, the greater your chances of cracking WEP.
When the Data category in the Scan window has reached a number between 20,000 and 30,000, press 8 on the keyboard to crack the key
Step 6. Copy the key
If the attack was successful, the key will be displayed in the lower right window. It will appear next to KEY FOUND. Make sure the Decrypted Correctly value is 100%, otherwise the key may not work.
The key will be displayed in both hexadecimal and ASCII format. The latter is the one in which the key is usually inserted when connecting to the network
Advice
- It can be difficult or impossible to crack a network with a poor signal.
- When entering the key in Windows you should use the ASCII key (the second one). If you want to use the hex key (the first one) you have to remove the ":".
- WiFiSlax live CD sometimes crashes or does not recognize the injection interface. The solution is to restart the operating system.
- WiFiSlax may be incompatible with some computers or may need some work to be used with a graphical interface.
- Sometimes the amount of data (#Data) required to successfully crack a network exceeds 30,000 packets. In some cases, it may take 1,000,000 or more packets to find the key.
- Sometimes package collection may begin after an hour or more. You can try again later, restart your computer or move your computer to another location.
- Pay particular attention to the type of network encryption - it must be WEP, not WPA.
