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. Aircrack Check Your Essid DefinitionThe WiFi Protected Setup protocol is vulnerable to a brute force attack that allows an attacker to recover an access points WPS pin, and subsequently the WPAWPA2. Aprenda como descobrir senha WiFi WPA, hackear rede wireless. Baixar programa hacker para hackear internet wifi, tutorial como descobrir senha Wifi WPA. WEP hacking is a joke. WPA is a nightmare. But with WPS enabled, any network can be hacked in nearly 3 hours using Reaver on Kali Linux. This tutorial shows how. You are using drivers patched for injection. Use the injection test to confirm your card can inject. Using Fluxion tool to hack a WPA2 network without using dictionarybruteforce. This method does not require WPS enabled either, and instead uses Evil Twin Man in. WiFi interview questions What is Piggybacking in context to WiFi, What are the recommended channels if you are setting up three WLANs and want minimum. 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. First things first disconnect from all wireless networks. Then open up terminal. In order to use Aircrack, youll need a wireless card that supports injections. Aircrack Check Your Essid VoyageType this into the Terminal to make sure your card supports it airmon ng. 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. Aircrack Check Your Essidant' title='Aircrack Check Your Essidant' />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. 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. Here is a list of security tools that have been collected from the internet. These tools are specifically aimed toward security professionals and enthusiasts. 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. Kali Linux Wi. Fi Hack Evil Twin Attack 2. UPDATEA Fake Wi. Fi access point is a wireless access point that has been installed on a secure network without explicit authorization from a local network administrator, whether added by a well meaning employee or by a malicious attacker. Fake Wi. Fi access point is often called as In previous chapters of this series, we have now learned to. But all of those methods were either too slow or too much resource consuming. Wouldnt it be better if we can harvest the Wi. Fi password in plain text to save our time, effort, energy and resources required for cracking the WPA2 hash Good news This is possible using the Fake Wi. Fi access point or the infamous Evil Twin attack method. This article is an excerpt from my Wi. Fi Penetration testing and. Security e. Book for aspiring Wi. Fi hackers and Wireless security enthusiasts. Click here to learn more. Using this method it is possible to retrieve the WPA2 passphrase in clear text within minutes, no need of cracking or any extra hardware other than a Wireless adapter. In some cases you dont even need an adapter, when Keep readingAs per decided road map of chapter 7 there are some changes that had to be made due to the release of Kali Linux 2. Previously until Kali Linux 1. Evil Twin access point and bridge the interface with the virtual machines default interface using brctl utility, but since Kali Linux 2. There were some conflicts between aircrack ng suite and network manager, So supposedly I have to make changes in the chapter to keep it up to date. We will not be using any automated script as thought earlier, but we will understand the concept and perform it manually so that you can make your own script to automate the task and make it simple and fast to use. Lets begin now Evil Twin Attack Methodology. Step 1 We will first scan the air for a target access point. Then create an access point using airbase ng with the same name and channel of the target access point, hence Evil TWIN attack. Step 2 The client is now disconnected repeatedly from the  original access point and as most modern systems setting says Connect back to same ESSID AP name if disconnects. This also happens because when the client disconnects from any access point it starts sending probe requests in the air with the name of the access point it connected to earlier. Hence BSSID isnt a barrier, you just need ESSID to spoof the APStep 3 Clients is now connected to the Evil Twin access point and now client may start browsing Internet. Nds Usa Roms English on this page. Step 4 Client will see a web administrator warning saying Enter WPA password to download and upgrade the router firmwareStep 5 The moment client enters the password, she will be redirected to a loading page and the password will be stored in the My. SQL database of the attacker machine. Scanning the air for client probe requests can lead you to crack WPA2 PSK passphrase without any existing Access point or sometimes without any handshake. Hardware used Software Used Installing required tools. So far we have aircrack ng suite of tools, apache, mysql, iptables pre installed in our Kali Linux virtual machine. We just need to install isc dhcp server for IP address allocation to the client. Install isc dhcp server in Kali Linux. Type in terminal apt getupdateapt getinstall isc dhcp server y. This will update the cache and install latest version of dhcp server in your Kali Linux box. Now all the required tools are installed. We need to configure apache and the dhcp server so that the access point will allocate IP address to the clientvictim and client would be able to access our webpage remotely. Enable publichtml remote access in apache. By default apache doesnt allow public access to remote connections. So we need to do some more work. In Ubuntu and other debian based distros, apaches default web directory is varwwwpublichtml. In case there is no such directory,  create one. Open terminal and type 1mkdirvarwwwpublichtml. Remember, In Kali Linux default apache web directory is varwwwhtml. So put all the rogueAP. Now youll need to enable remote access to the publichtml directory. Type in terminal 1geditetcapache. Enable the new userdir configuration file. Now we will define the IP range and the subnet mask for the dhcp server. Configure isc dhcp server. Type in terminal 1geditetcdhcpdhcpd. Your dhcpd. conf file will look like thisOptionalResolve airmon ng and Network Manager Conflict. Before enabling monitor mode on the wireless card lets fix the airmon ng and network manager conflict forever. So that we dont need to kill the network manager or disconnect tany network connection before putting wireless adapter into monitor mode as we used to run airmon ng check kill every time we need to start wifi pentest. Open terminal and type 1geditetcNetwork. ManagerNetwork. Manager. Now add the following at the end of the filekeyfileunmanaged devicesinterface name wlan. Output should look like this. Now that you have edited the Network. Manager. conf file you should have no conflicts with airmon ng in Kali Linux 2. We are ready to begin now. Bring up the wireless interface. Your could be wlan. Put wireless adapter into monitor mode. Putting the card in monitor mode will show a similar output. Now our card is in monitor mode without any issues with network manager. You can simply start monitoring the air with command. As soon your target AP appears in the airodump ng output window press CTRL C and note these three things in a text editorGedit, in caseSet tx power of alfa card to max 1. Wtx power stands for transmission power. By default it is set to 2. BmDecibel metre or 1. W. tx power in m. W increases 1. 0 times with every 1. Bm. See the d. Bm to m. W table. If your country is set to US while installation. Bm1. 00. 0 m. WIn Kali Linux 2. Codename Sana You might face issue while powering up your card. As in earlier versions if you set countryregion to Bolivia, you are able to operate card at 3. Bm. But in Kali Sana is not working. So well be using US as our region. Renaming Multiple Rar Files here. Here is howifconfig wlan. Bring down the interfaceiw reg set US    Set region to be USifconfig wlan. Bring the interface upiwconfig wlan. Check tx power, should be 3. Bm. If you are thinking why we need to change region to operate our card at 1. W. Here is whybecause different countries have different legal allowance of Wireless devices at certain power and frequency. That is why Linux distribution have this information built in and you need to change your region to allow yourself to operate at that frequency and power. Motive of powering up the card is that when creating the hotspot you do not have any need to be near to the victim. Start Evil Twin Attack. Begin the Evil Twin attack using airbase ng 1airbase ng   erootsh. For the at. 0 to allocate IP address we need to assign an IP range to itself first. Allocate IP and Subnet Mask. Here we have allocated Class C IP address to the at. Subnet Mask and 1. IPDo not confuse between Network address and default gateway. Network address is also called the network node. Nodes are the reserved IP address of any specific range. Android Russian Keyboard. X. X. X. 0 and X. X. X. 2. 55 are always reserved that is why IP range always varies from X. X. X. 1 2. 54.
