How Can U Hack Someone’S Wifi
How to Hack Wi-Fi Passwords | PCMag
Chances are you have a Wi-Fi network at home, or live close to one (or more) that tantalizingly pops up in a list whenever you boot up your laptop or look at the problem is, if there’s a lock next to the network name (AKA the SSID, or service set identifier), that indicates security is activated. Without a password or passphrase, you’re not going to get access to that network, or the sweet, sweet internet that goes with rhaps you forgot the password on your own network, or don’t have neighbors willing to share the Wi-Fi goodness. Pre COVID-19, you could just go to a café, buy a latte, and use the “free” Wi-Fi there (vaccines willing, maybe you’ll do it again soon). Download an app for your phone like WiFi-Map (available for iOS and Android), and you’ll have a list of millions of hotspots with free Wi-Fi for the taking (including some passwords for locked Wi-Fi connections if they’re shared by any of the app’s users). However, there are other ways to get back on the wireless. Some require such extreme patience that the café idea, even in quarantine, is going to look pretty good. Read on if you can’t wait.
Windows Commands to Get the KeyThis trick works to recover a Wi-Fi network password (AKA network security key) only if you’ve previously attached to the Wi-Fi in question using that very password. In other words, it only works if you’ve forgotten a previously used works because Windows 8 and 10 create a profile of every Wi-Fi network to which you connect. If you tell Windows to forget the network, then it also forgets the password. In that case, this won’t work. But few people ever explicitly do requires that you go into a Windows Command Prompt with administrative privileges. Click the Star Menu, type “cmd” (no quotes), and the menu will show Command Prompt; right-click that entry and select Run as administrator. That’ll open the black box full of text with the prompt inside—it’s the line with a right-facing arrow at the end, probably something like C:\WINDOWS\system32\>. A blinking cursor will indicate where you type. Start with this:netsh wlan show profile
The results will bring up a section called User Profiles—those are all the Wi-Fi networks (aka WLANs, or wireless local area networks) you’ve accessed and saved. Pick the one you want to get the password for, highlight it, and copy it. At the prompt below, type the following, but replace the Xs with the network name you copied; you only need the quotation marks if the network name has spaces in it, like “Cup o Jo Cafe. “netsh wlan show profile name=”XXXXXXXX” key=clearIn the new data that comes up, look under Security Settings for the line Key Content. The word displayed is the Wi-Fi password/key you are macOS, open up the Spotlight search (Cmd+Space) and type terminal to get the Mac equivalent of a command prompt. Type the following, replacing the Xs with the network curity find-generic-password -wa XXXXXReset the RouterThis isn’t for getting on someone else’s Wi-Fi in the apartment next door. You need physical access to the router for this to work. But, before you do a full router reset simply to get on your own Wi-Fi, try to log into the router first. From there, you can easily reset your Wi-Fi password/key if you’ve forgotten ‘s not possible if you don’t know the password for the router. (The Wi-Fi password and router password are not the same—unless you went out of your way to assign the same password to both). Resetting the router only works if you have access via Wi-Fi (which we’ve just established you don’t have) or physically, utilizing an Ethernet you’ve got a router that came from your internet service provider (ISP), check the stickers on the unit before a reset—the ISP might have printed the SSID and network security key right on the use the nuclear option: Almost every router in existence has a recessed reset button. Push it with a pen or unfolded paperclip, hold it for about 10 seconds, and the router will reset to the factory settings.
Once a router is reset, you’ll need that other username/password combo to access the router itself. Again, do this via a PC attached to the router via Ethernet—resetting the router probably killed any potential Wi-Fi connection for the moment. The actual access is typically done with a web browser, though many routers and mesh systems now can be controlled via an routers may also have a sticker with that default Wi-Fi network name (SSID) and network security key (password) so you can indeed go back on the Wi-Fi after a URL to type into the browser to access a router’s settings is typically 192. 168. 1. 1 or 192. 0. 1, or some variation. Try them randomly; that generally works. To determine which one on a PC connected to the router via Ethernet, open a command prompt and type ipconfig. Look among the gobbledygook for an IPv4 Address, which will start with 192. The other two spaces, called octets, are going to be different numbers between 0 and 255. Note the third octet (probably a 1 or 0). The fourth is specific to the PC you’re using to log into the the browser, type 192. x. 1, replacing the X with the number you found in the ipconfig search. The 1 in the last octet should point at the router—it’s the number one device on the network. (For full details, read How to Access Your Wi-Fi Router’s Settings. )At this point, the router should then ask for that username and password (which, again, is probably not the same as the Wi-Fi SSID and network security key). Check your manual, assuming you didn’t throw it away, or go to, which exists for one reason: to tell people the default username/password on every router ever created. You’ll need the router’s model number in some cases, but not all.
You will quickly discern a pattern among router makers of utilizing the username of “admin” and a password of “password, ” so feel free to try those first. Since most people are lazy and don’t change an assigned password, you could try those options even before hitting the reset button. (But c’mon, you’re better than that. ) Once you’re in the Wi-Fi settings, turn on the wireless network(s) and assign strong-but-easy-to-recall passwords. After all, you don’t want to share with neighbors without your that Wi-Fi password easy to type on a mobile device, too. Nothing is more frustrating than trying to get a smartphone connected to Wi-Fi with some cryptic, impossible to key-in-via-thumbs nonsense, even if it is the most secure password you’ve ever the CodeYou didn’t come here because the headline said “reset the router, ” though. You want to know how to crack the password on a Wi-Fi arching on “wi-fi password hack, ” or other variations, nets you a lot of links—mostly for software on sites where the adware and bots and scams pour like snake oil. The same goes for the many, many YouTube videos promising you ways to crack a password by visiting a certain website on your phone. Download those programs or visit those sites at your own risk, knowing many are phishing scams at best. We recommend using a PC you can afford to mess up a bit if you go that route. When I tried it, multiple tools were thankfully outright deleted by my antivirus before I could even try to run the EXE installation file.

Kali LinuxYou could create a system just for this kind of thing, maybe dual-boot into a separate operating system that can do what’s called “penetration testing”—a form of offensive approach security, where you examine a network for any and all possible paths of a breach. Kali Linux is a Linux distribution built for just that purpose. You probably saw it used on Mr. Robot. Check out the video tutorial can run Kali Linux off a CD or USB key without even installing it to your PC’s hard drive. It’s free and comes with all the tools you’d need to crack a network. It even has an app for Windows 10 in the Windows App you don’t want to install a whole OS, then try the tried-and-true tools of Wi-Fi rcrackAircrack has been around for years, going back to when Wi-Fi security was only based on WEP (Wired Equivalent Privacy). WEP was weak even back in the day; it was supplanted in 2004 by WPA (Wi-Fi Protected Access). Aircrack-ng is labeled as a “suite of tools to assess Wi-Fi network security, ” so it should be part of any network admin’s toolkit. It will take on cracking WEP and WPA-PSK keys. It comes with full documentation and is free, but it’s not simple. To crack a network, you need to have the right kind of Wi-Fi adapter in your computer, one that supports packet injection. You need to be comfortable with the command line and have a lot of patience. Your Wi-Fi adapter and Aircrack have to gather a lot of data to get anywhere close to decrypting the passkey on the network you’re targeting. It could take a while. Here’s a how-to on doing it using Aircrack installed on Kali Linux and another on how to use Aircrack to secure your network. Another similar option on the PC using the command line is the much stronger WPA/WPA2 passwords and passphrases is the real trick. Reaver-wps is the one tool that appears to be up to the task. You’ll need that command-line comfort again to work with it. After two to 10 hours of brute-force attacks, Reaver should be able to reveal a password… but it’s only going to work if the router you’re going after has both a strong signal and WPS (Wi-Fi Protected Setup) turned on. WPS is the feature where you can push a button on the router and another button on a Wi-Fi device, and they find each other and link auto-magically, with a fully encrypted connection. It’s the “hole” through which Reaver if you turn off WPS, sometimes it’s not completely off, but turning it off is your only recourse if you’re worried about hacks on your own router via Reaver. Or, get a router that doesn’t support WPS. Hacking Wi-Fi over WPS is also possible with some tools on Android, which only work if the Android device has been rooted.

Tech Tips: WiFi can be used to hack your phone, here’s how to …
WiFi hacking is easier than hacking a device connected to that WiFi. There are many free tools that can hack the less secure WiFi router. HIGHLIGHTSRouters with WEP security are easy to hackThe most common mistake that many of us do is using the default WiFi password. Hacking is a whole new technology in itself. The techniques of hacking are rapidly growing in numbers with hackers everyday coming up with new ideas to steal our personal data. One such widely preferred ways of hacking is the WiFi hacking. It is mainly of two types- one in which the hacker intercepts your WiFi to connect her or her own device and second which is the more dangerous one in which hacker hacks your WiFi to reach to your connected device.
Hackers many a times leave the WiFi open to all to use it as a bait. When someone connects the device to this open WiFi, their device’s MAC address and IP address are registered in the router. Hacker first intercepts the traffic by using the sniffing tool. Data is transferred as packets. These packets are intercepted by the hackers to easily detect your browsing hacking is easier than hacking a device connected to that WiFi. Apart from this, there are also advanced tools that work on backtrack and can even hack WiFi router with high uters with WEP security are easy to hack. WEP is a type of encryption tool used to secure your wireless connection. However, routers these days are secured with WPA-PSK keys which are tough to hack but this doesn’t mean that these are most common mistake that many of us do is using the default WiFi password. Hackers can use the default password to not only hack your WiFi connection but also gain access to the connected are several ways to protect your WiFi and your device from malicious minds. For example- change your WiFi password frequently, don’t connect your phone or laptop to an unknown and open WiFi connection, and do not leave your WiFi open. Apart from these, you can also block other uses from accessing your WiFi router. This can be done using an app named Fing ‘s how to use the Fing app:– Download the Fing app from Play Store or App store. — Open the app once it is installed on your device and look for WiFi connectivity on the home screen. — You will find Refresh and Settings options inside WiFi connectivity. — Refresh will show you the list of devices that are connected to your router. It will even inform you if the connected device is a laptop or mobile. — You can also see the MAC address of the connected devices. Copy the device MAC address of the device that you want to block.

How to Hack WiFi Password: Guide to Crack Wireless Network
Wireless networks are accessible to anyone within the router’s transmission radius. This makes them vulnerable to attacks. Hotspots are available in public places such as airports, restaurants, parks, etc.
In this tutorial, we will introduce you to common techniques used to exploit weaknesses in wireless network security implementations. We will also look at some of the countermeasures you can put in place to protect against such attacks.

How to Hack WiFi Password
A wireless network is a network that uses radio waves to link computers and other devices together. The implementation is done at the Layer 1 (physical layer) of the OSI model.
You will need a wireless network enabled device such as a laptop, tablet, smartphones, etc. You will also need to be within the transmission radius of a wireless network access point. Most devices (if the wireless network option is turned on) will provide you with a list of available networks. If the network is not password protected, then you just have to click on connect. If it is password protected, then you will need the password to gain access.
Wireless Network Authentication
Since the network is easily accessible to everyone with a wireless network enabled device, most networks are password protected. Let’s look at some of the most commonly used authentication techniques.
WEP is the acronym for Wired Equivalent Privacy. It was developed for IEEE 802. 11 WLAN standards. Its goal was to provide the privacy equivalent to that provided by wired networks. WEP works by encrypting the data been transmitted over the network to keep it safe from eavesdropping.
Open System Authentication (OSA) – this methods grants access to station authentication requested based on the configured access policy.
Shared Key Authentication (SKA) – This method sends to an encrypted challenge to the station requesting access. The station encrypts the challenge with its key then responds. If the encrypted challenge matches the AP value, then access is granted.
WEP has significant design flaws and vulnerabilities.
The integrity of the packets is checked using Cyclic Redundancy Check (CRC32). CRC32 integrity check can be compromised by capturing at least two packets. The bits in the encrypted stream and the checksum can be modified by the attacker so that the packet is accepted by the authentication system. This leads to unauthorized access to the network.
WEP uses the RC4 encryption algorithm to create stream ciphers. The stream cipher input is made up of an initial value (IV) and a secret key. The length of the initial value (IV) is 24 bits long while the secret key can either be 40 bits or 104 bits long. The total length of both the initial value and secret can either be 64 bits or 128 bits lower possible value of the secret key makes it easy to crack it.
Weak Initial values combinations do not encrypt sufficiently. This makes them vulnerable to attacks.
WEP is based on passwords; this makes it vulnerable to dictionary attacks.
Keys management is poorly implemented. Changing keys especially on large networks is challenging. WEP does not provide a centralized key management system.
The Initial values can be reused
Because of these security flaws, WEP has been deprecated in favor of WPA
WPA is the acronym for Wi-Fi Protected Access. It is a security protocol developed by the Wi-Fi Alliance in response to the weaknesses found in WEP. It is used to encrypt data on 802. 11 WLANs. It uses higher Initial Values 48 bits instead of the 24 bits that WEP uses. It uses temporal keys to encrypt packets.
The collision avoidance implementation can be broken
It is vulnerable to denial of service attacks
Pre-shares keys use passphrases. Weak passphrases are vulnerable to dictionary attacks.
Cracking is the process of exploiting security weaknesses in wireless networks and gaining unauthorized access. WEP cracking refers to exploits on networks that use WEP to implement security controls. There are basically two types of cracks namely;
Passive cracking– this type of cracking has no effect on the network traffic until the WEP security has been cracked. It is difficult to detect.
Active cracking– this type of attack has an increased load effect on the network traffic. It is easy to detect compared to passive cracking. It is more effective compared to passive cracking.
WEP Cracking (Hacking) Tools
Aircrack– network sniffer and WEP cracker. This WiFi password hacker tool can be downloaded from WEPCrack– this is an open source Wi-Fi hacker program for breaking 802. 11 WEP secret keys. This WiFi hacker app for PC is an implementation of the FMS attack. Kismet– this WiFi password hacker online detects wireless networks both visible and hidden, sniffer packets and detect intrusions. WebDecrypt– this WiFi password hack tool uses active dictionary attacks to crack the WEP keys. It has its own key generator and implements packet filters for hacking WiFi password.
WPA uses a 256 pre-shared key or passphrase for authentications. Short passphrases are vulnerable to dictionary attacks and other attacks that can be used to crack passwords. The following WiFi hacker online tools can be used to crack WPA keys.
CowPatty– this WiFi password cracker tool is used to crack pre-shared keys (PSK) using brute force attack. Cain & Abel– this WiFi hacker for PC tool can be used to decode capture files from other sniffing programs such as Wireshark. The capture files may contain WEP or WPA-PSK encoded frames.
General Attack types
Sniffing– this involves intercepting packets as they are transmitted over a network. The captured data can then be decoded using tools such as Cain & Abel.
Man in the Middle (MITM) Attack– this involves eavesdropping on a network and capturing sensitive information.
Denial of Service Attack– the main intent of this attack is to deny legitimate users network resources. FataJack can be used to perform this type of attack. More on this in article
Cracking Wireless network WEP/WPA keys
It is possible to crack the WEP/WPA keys used to gain access to a wireless network. Doing so requires software and hardware resources, and patience. The success of such WiFi password hacking attacks can also depend on how active and inactive the users of the target network are.
We will provide you with basic information that can help you get started. Backtrack is a Linux-based security operating system. It is developed on top of Ubuntu. Backtrack comes with a number of security tools. Backtrack can be used to gather information, assess vulnerabilities and perform exploits among other things.
Some of the popular tools that backtrack has includes;
Cracking wireless network keys requires patience and resources mentioned above. At a minimum, you will need the following tools
A wireless network adapter with the capability to inject packets (Hardware)
Kali Operating System. You can download it from here Be within the target network’s radius. If the users of the target network are actively using and connecting to it, then your chances of cracking it will be significantly improved.
Sufficient knowledge of Linux based operating systems and working knowledge of Aircrack and its various scripts.
Patience, cracking the keys may take a bit of sometime depending on a number of factors some of which may be beyond your control. Factors beyond your control include users of the target network using it actively as you sniff data packets.
In minimizing wireless network attacks; an organization can adopt the following policies
Changing default passwords that come with the hardware
Enabling the authentication mechanism
Access to the network can be restricted by allowing only registered MAC addresses.
Use of strong WEP and WPA-PSK keys, a combination of symbols, number and characters reduce the chance of the keys been cracking using dictionary and brute force attacks.
Firewall Software can also help reduce unauthorized access.
In this practical scenario, we are going to learn how to crack WiFi password. We will use Cain and Abel to decode the stored wireless network passwords in Windows. We will also provide useful information that can be used to crack the WEP and WPA keys of wireless networks.
Decoding Wireless network passwords stored in Windows
Step 1) Download the Cain and Abel tool
Download Cain & Abel from the link provided above.
Open Cain and Abel
Step 2) Select the Decoders tab and choose Wireless passwords
Ensure that the Decoders tab is selected then click on Wireless Passwords from the navigation menu on the left-hand side
Click on the button with a plus sign
Step 3) The passwords will be shown
