How to Hack Your Own Network and Beef Up Its Security with Kali Linux. Kali Linux is a security focused operating system you can run off a CD or USB drive, anywhere. With its security toolkit you can crack Wi Fi passwords, create fake networks, and test other vulnerabilities. Heres how to use it to give your own a network a security checkup. This post is part of our Evil Week series at Lifehacker, where we look at the dark side of getting things done. Knowing evil means knowing how to beat it, so you can use your sinister powers for good. Want more Check out our evil week tag page. Its that time of year again With Halloween getting closer, were feeling the need toRead more Read. Kali Linux is packed with a ton of software for testing security holes in your network. There are far too many to list here, but were so enamored with it that we decided to pick a few of our favorite tools and show how they work Aircrack, Airbase, and ARPspoof. Well show you how to crack a Wi Fi password with brute force techniques, create a fake router to trick machines into logging into it, and perform a man in the middle attack to eavesdrop on network communications. Remember use these powers for good, not for evil. Knowing how to do these things can get you out of a jam or help you learn to secure your own network, but doing them to someone else is not something we recommend. Crack a WPA Wi Fi Password with Aircrack. Kali Linux comes with a whole suite of apps for cracking Wi Fi networks, including Aircrack and Reaverboth of which weve mentioned before for. WEP and WPA passwords, respectively. You already know that if you want to lock down your Wi Fi network, you should opt for WPARead more Read. However, WEP passwords arent that popular anymore because theyre so easy to crack, and Reaver only works if a network has WPS enabled. So today, were going take another look at Aircrack and use it to to brute force our way into a WPA network with the help of a password list. Step One Configure Your Wireless Card.

Then open up terminal. In order to use Aircrack, youll need a wireless card that supports injections. Type this into the Terminal to make sure your card supports it airmon ng. How to Hack a Computer. Hacking a computer is a useful and, at rare times, an important skill to pick up. Below are instructions for getting past a password if you. WiFi Password Hacker for PC, Hack Wifi Password, Download WiFi hacker for PC, WiFi password hacker software, WiFi Password Hacking, Wifi Hacker Online App. Home of Kali Linux, an Advanced Penetration Testing Linux distribution used for Penetration Testing, Ethical Hacking and network security assessments. This lists all the wireless cards that support this crack. If you card doesnt support injections, it wont show up here. Yours is likely listed under interface as wlan. Next, type in airmon ng start wlan. You should get a message back saying that monitor mode was enabled. Step Two Monitor Your Network. Next, youre going to get a list of all the networks in your area and monitor yours. Type in airodump ng mon. Youll see all the networks in your area. Locate your network from the list, and copy the BSSID, while making a note of the channel its on. Tap CtrlC to stop the process. Next, type this in, replacing the information in parentheses with the information you gathered above airodump ng c channel bssid bssid w rootDesktop monitor interface. It should read something like this airodump ng c 6 bssid 0. E 6. 4 9. 8 9. AB w rootDesktop mon. Now, youll be monitoring your network. You should see four files pop up on the desktop. Dont worry about those now youll need one of them later. The next step is a bit of a waiting game, as youll be sitting around waiting for a device to connect to a network. In this case, just open up a device you own and connect to your Wi Fi. You should see it pop up as a new station. Make a note of the station number, because youll need that in the next step. Step Three Capture a Handshake. Now, youre going to force a reconnect so you can capture the handshake between the computer and the router. Leave Airodump running and open up a new tab in Terminal. Then type in aireplay ng 0 2 a router bssid c client station number mon. It should look something like aireplay ng 0 2 a 0. E 6. 4 9. 8 9. AB c 5. E 8. EA mon. 0. Youll now see Aireplay send packets to your computer to force a reconnect. Hop back over to the Airodump tab and youll see a new number listed after WPA Handshake. If thats there, youve successfully grabbed the handshake and you can start cracking the password. Step Four Crack the Password. Vp Suite 5.2 Crack. You now have the routers password in encrypted form, but you still need to actually figure out what it is. To do this, youll use a password list to try and brute force your way into the network. You can find these lists online, but Kali Linux includes a few small lists to get you started in the usrsharewordlists directory, so well just use one of those. To start cracking the password type this in aircrack ng a. RootDesktop. cap. So, continuing with our above example and using one of the built in wordlists, it should read something like aircrack ng a. E 6. 4 9. 8 9. AB w usrsharewordlistsfern wificommon. RootDesktop cap. Now, Aircrack will try all of those passwords to see if one fits. If it does, youll get a message saying the key was found with the password. If not, give another one of the password lists a try until you find one that works. The bigger the password list, the longer this process will take, but the greater chance you have of succeeding. How to Use This Information to Stay Safe. So, you just brute forced your way into your own network. Depending on how good your password is, it either took you five minutes or five hours. If your password is something simple, like password. If it was more complicated, it probably took a long time or never surfaced the password at all if so good for you. The best protection here is a. The longer, weirder, and more complex it is, the better. Likewise, make sure youre using the WPA2 security protocol and you dont have WPS enabled. How do you balance the necessity of highly secure passwords with the utility of easily recallingRead more Read. Create a Fake Network with Airbase. Next up, lets take a look at how you can spoof a network address to trick people into signing into the wrong network so you can watch what theyre doing. Hackers might do this so you sign into the fake network thinking its your real one, then performing a man in the middle attack more on that in the next section to gather information about you from your traffic. This is amazingly easy to do with a tool in Kali Linux called Airbase. Essentially, youll turn your Wi Fi adapter on Kali Linux into an access point with the same name as another network. In order to do this, youll follow the same line of research as you did above, but the endings a bit different. Step One Configure Your Wireless Card. Just like last time, you need to set up your wireless card to monitor traffic. Open up Terminal and type airmon ng. This lists all the wireless cards that support this crack. Yours is likely listed under interface as wlan. Next, type in airmon ng start wlan. Now youre in monitor mode. Its time to find the network you want to spoof. Step Two Find a Wi Fi Network to Spoof. In order to spoof a router, youll need some information about it. So, type in airodump ng mon. Youll see all the networks in your area. Locate your network from the list and copy the BSSID, while making a note of its name and the channel its on. This is the router youre going to spoof. Tap CtrlC to stop the process. Step Three Create a Fake Network. Now, youre going to create the fake network with Airbase.
