This will open a dialog box that will allow you to filter the table by encryption type, signal strength, channel, etc.


How to launch different types of attacks on WEP, WPA, WPS, etc.




After you have scanned and identified the wireless networks and access points that you want to target, you can launch different types of attacks on them using Fern Wifi Cracker. These include:


  • WEP (Wired Equivalent Privacy) attack: This is an attack that can crack and recover WEP keys using various methods such as fragmentation, chop-chop, caffe-latte, hirte, arp request replay, etc. WEP is an outdated and insecure encryption standard that can be easily broken by modern tools and techniques.



  • WPA (Wi-Fi Protected Access) attack: This is an attack that can crack and recover WPA keys using a dictionary or wordlist file that contains possible passwords or phrases. WPA is a more secure encryption standard than WEP, but it can still be vulnerable if the key is weak or common.



  • WPS (Wi-Fi Protected Setup) attack: This is an attack that can crack and recover WPS pins using a brute force method that tries all possible combinations of digits. WPS is a feature that allows users to connect to a wireless network by pressing a button or entering a pin, but it can also be exploited by attackers if the pin is not randomized or disabled.



To launch different types of attacks on WEP, WPA, WPS, etc., you need to follow these steps:


  • Select the wireless network or access point that you want to attack from the table. You can do this by clicking on the row that corresponds to the network or access point. You should see a green check mark next to the selected row.



  • Click on the Attack button on the bottom left corner of the Fern Wifi Cracker window. This will open a dialog box that will show you the available attack options for the selected network or access point.

  • Click on OK to confirm your selection and start the attack. This will open a terminal window that will run some commands and tools to launch the attack using Aircrack-ng suite.



  • You should see some output and feedback on the terminal window, indicating that the attack is in progress. You should also see a progress bar on the bottom left corner of the Fern Wifi Cracker window, indicating that the attack is in progress.



  • Wait for the attack to complete or stop the attack by clicking on the Stop button on the bottom left corner of the Fern Wifi Cracker window.



  • Close the terminal window and return to the Fern Wifi Cracker window. You should see a message that shows the result of the attack, such as the cracked key or pin, or an error message if the attack failed.



How to capture and crack the keys and passwords




After you have launched an attack on a wireless network or access point, you may be able to capture and crack the keys and passwords that are used to secure the network or access point. These include:


  • WEP key: This is a hexadecimal string that is used to encrypt and decrypt the data packets that are transmitted or received by the wireless devices on a WEP network. A WEP key can be 64 bits (10 hex digits) or 128 bits (26 hex digits) long.



  • WPA key: This is a passphrase or a pre-shared key that is used to generate a pairwise master key (PMK) that is used to encrypt and decrypt the data packets that are transmitted or received by the wireless devices on a WPA network. A WPA key can be 8 to 63 characters long.



  • WPS pin: This is an 8-digit numerical code that is used to authenticate and connect a wireless device to a WPS-enabled access point. The first 4 digits are randomly generated, while the last 4 digits are derived from the first 4 digits using a checksum algorithm.



To capture and crack the keys and passwords, you need to follow these steps:
