How to hack networks with Wi-Fi passwords

how-to-hack-wi-fi

You probably have a Wi-Fi network in your home or stay close to one (or more) that appear in a list every time you start your computer. The problem is that if there is a key next to the network name (SSID or service set identifier), it means that the security is turned on. Without the password or passphrase, you will not be able to access this network.

how-to-hack-wi-fi

You may have forgotten your network password or you do not have neighbors wishing to share their Wi-Fi. You could go to a cafe and use the "free" Wi-Fi there. Download an app for your phone like WiFi-Map (available for iOS and Android) and you'll have a list of over 2 million hotspots with free Wi-Fi (including some passwords for locked Wi-Fi if shared by any of the 7 million users of the app).

However, there are other ways to go back to the wireless internet. This trick tries to retrieve a Wi-Fi network password (also known as a network security key) only if you previously signed in to that Wi-Fi using the same passcode. In other words, it only works if you have forgotten a password that was previously used, as Windows 8 and 10 create a profile for each Wi-Fi network you connect to.

If you tell Windows to forget about the network, then it forgets the password, so this practice will not work. But most people will rarely go into this process.

Go to a Command Line Windows with administrator rights. To do this, use Cortana to search for "cmd" and the Command Prompt command will appear in the menu. right-click the entry and select "Run as administrator". This will open the black box filled with white text with the command inside - it is the line with> at the end, probably something like C: \ WINDOWS \ system32 \>. A blinking cursor will indicate which type you are typing. Start with this:

netsh wlan show profiles

The results will show a section called "User Profiles" - these are all Wi-Fi networks (also known as WLANs or wireless local area networks) that you accessed and saved. Choose the one you want to get your password and copy it. In the following message, type the following, but replace X with the network name you copied. You need quotes only if the network name has gaps in it.

netsh wlan show profile name = »XXXXXXXX» key = clear

In the new data that appears, see Security Settings for the "Basic Content" line. The word that appears is the missing Wi-Fi code / key. In the MacOS, open the Spotlight search (Cmd + Space) and type "terminal" to access the corresponding command line. Type the following by replacing X with the network name.

security find-generic-password-to XXXXX

Before making a full reset of the router simply to get into the wireless network, try first to connect to the router. From there, you can easily reset your Wi-Fi password / key if you have forgotten it. This is not possible if you do not know the password for the router. The reset of the router works only if you have access. This access could be via Wi-Fi or, of course, using an Ethernet cable.

Almost every router has a reset button. Push it with a pen or collapsible clip, hold it for about 10 seconds, and the router returns to the factory settings.
If you have a router from your ISP, check the stickers on the device before resetting - the ISP may have printed the Wi-Fi key directly on the hardware.

Once the router is reset, you need another password (plus a username) to access the router itself. Access is usually done with a web browser.
The URL you type is either 192.168.1.1 or 192.168.0.1 or a variant. To figure out what's right, open a command line and type 'ipconfig' without quotes. Look for an "IPv4 address", which starts with 192.168. The other two spaces, called octaves, will be different numbers between 0 and 255. Mark the third octet (possibly 1 or 0). The fourth is specific for the computer you use to connect to the router.

In the browser, type 192.168.x.1, replacing X with the number you found in ipconfig search. 1 in the last octet should "show" the router - it is the number one device on the network.

At this point, the router should ask for username and password. You can check your manual, but you've probably missed it or you've thrown it. So instead, go to RouterPasswords.com, and find the default username / password for each router ever created.

You'll need the router's model number, but that's pretty easy to find on the back or bottom. You will see a pattern between router manufacturers having the admin username and a password with a password. Since most people do not change the factory password, you could try these options before tapping the reset button. Once you have access to the router, go to Wi-Fi settings, turn on wireless networks, and create strong passwords.

By searching for the term "wi-fi hack password", or other variations, many links are given by software search engines to sites with adwares, bots and other scams. Download them at your own risk, especially for Windows computers. If you do not want to risk, try some of the known hacker tools. Aircrack, for example, counts many years of traffic and started its action when Wi-Fi security was still based on Wired Equivalent Privacy (WEP). WEP was weak from the outset and 2004 was replaced by WPA (Wi-Fi Protected Access).

Aircrack, which is referred to as the "Wireless Network Control Toolbox", undertakes to remove the WEP and WPA-PSK keys. It comes with a full guide but is not simple to use. To break a network, you need to have the right kind of Wi-Fi adapter on your computer that supports packet distribution. You have to know the command line well and have a lot of patience. Your Wi-Fi adapter and Aircrack need to gather lots of data to get close to the decryption of the network password you are targeting. Such actions can take a long time. You can use Aircrack installed on Kali Linux distribution. Another option on a computer that uses the command line is Airgeddon.

If you prefer a graphical user interface (GUI), there is KisMAC for macOS. It is known as "sniffer" for searching for Wi-Fi networks. Something we do not need a lot these days, as our phones and tablets do a great job of showing us every Wi-Fi signal around us. It may, however, break some keys with the correct adapter installed. Also for Mac there is Wi-Fi Crack. To use them, you need to install them with MacPorts, a tool for installing command line products on Mac.

The real thing is cracking the much stronger WPA / WPA2 passwords and passphrases.

Reaver-wps is the one tool that seems to respond to this test. You will again need good command line knowledge to try it out. After two to ten hours of brute force attacks, Reaver will be able to reveal a password but will only work if the router you want to access has a strong signal and WPS (Wi-Fi Protected Setup) is active. WPS is the feature that lets you press a button on the router and a corresponding one on a Wi-Fi device and connects to one another with a fully encrypted connection. It is also the "hole" through which Reaver detects.

Wi-Fi hacking via WPS is also possible with some Android tools, which only work if the Android device has become root. Check the Wifi WPS WPA Tester, Reaver for Android or Kali Linux Nethunter as your options.
