What is a wireless network?

A wireless network connects computers and other devices by means of radio waves. At Layer 1 (the physical layer) of the OSI model, implementation takes place.

How to access a wireless network?

You will need a wireless network enabled device such as a laptop, tablet, smartphones, etc. Youwill 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 NetworkAuthentication

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

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 itsafe from eavesdropping.

WEP Authentication

According to the established access policy, Open System Authentication (OSA) is a method that grants access to stations that request authentication.

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 Weakness

WEP has significantdesign 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 long.The lower possible value of the secret key makes it easy to crack it.
  • Weak Initial values combinations do not encrypt sufficiently. This makes themvulnerable 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

WPA is the acronym forWi-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.

WPA Weaknesses

  • The collision avoidance implementation can be broken
  • It is vulnerable to denial of service attacks
  • Pre-shares keys use passphrases. Weak passphrases arevulnerable to dictionary attacks.

How to Crack WiFI (Wireless) Networks

WEP cracking

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;

  • Passivecracking– 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.

WiFi Password Hacker (WEP Cracking) Tools

  • Aircrack– network sniffer and WEP cracker. This WiFipassword hacker tool can be downloaded from http://www.aircrack-ng.org/
  • 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.http://wepcrack.sourceforge.net/
  • Kismet– this WiFi password hacker online detects wireless networks both visible and hidden, sniffer packets and detect intrusions. https://www.kismetwireless.net/
  • WebDecrypt– this WiFi password hacktool uses active dictionary attacks to crack the WEP keys. It has its own key generator and implements packet filters for hacking WiFi password. http://wepdecrypt.sourceforge.net/

WPA Cracking

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. http://wirelessdefence.org/Contents/coWPAttyMain.htm
  • Cain & Abel– this WiFi hacker for PC tool can be used to decode capture files from othersniffing programs such as Wireshark. The capture files may contain WEP or WPA-PSK encoded frames. https://www.softpedia.com/get/Security/Decrypting-Decoding/Cain-and-Abel.shtml

General Attack types

  • Sniffing– this involves intercepting packets as they are transmitted over a network. The captured datacan 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 inarticle

Cracking Wireless network WEP/WPA keys

The WEP/WPA keys required to access a wireless network can be broken. To do so, you’ll need patience, as well as hardware and software resources. How active and inactive the users of the target network are can also affect the success of such WiFi password hacking attempts.

We’ll give you some fundamental knowledge to get you going. The security operating system Backtrack runs on Linux. It was built on top of Ubuntu. A variety of security tools are provided with Backtrack. Backtrack can be used for information gathering, vulnerability analysis, and exploit development among other things.

Some of the popular tools that backtrack has includes;

  • Metasploit
  • Wireshark
  • Aircrack-ng
  • NMap
  • Ophcrack

Cracking wireless network keys requires patience andresources 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 https://www.kali.org/downloads/
  • Be within the target network’s radius. If the users of thetarget 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 asyou sniff data packets.

How to Secure wireless networks

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 byallowing 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 WiFipassword. 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

Can I see Wi-Fi password on Android? : Open Settings and navigate to Network and internet to view a Wi-Fi password on Android 10 or later. Tap Wi-Fi on an Android 10 or 11. You must choose Internet on Android 12 in its place. Following that, the top of the list will display your current Wi-Fi network.
Read Detail Answer On Can I see Wi-Fi password on Android?

Maybe you’re connected to a network where the password has been forgotten, or you want to check the password for a friend’s network so you can connect another device to it.

No matter the reason, we’ll show you how to find saved Wi-Fi passwords on Android using a few different methods

These are limited to networks that you’ve previously connected to and only display passwords for those. You must ask a network administrator for the password if you want to use them to find the Wi-Fi password for a network you have never joined.

You shouldn’t share the password for a network someone else manages unless you have their permission.

How to See Wi-Fi Passwords on Android Without Root

Wi-Fi passwords for your saved networks can be viewed on Android 10 and later without a rooted device. The procedure may differ slightly depending on your phone and Android version, so let’s take a look at how to do it on a Pixel device running stock Android 12.

To view a Wi-Fi password on Android 10 or later, open Settings and head to Network & internet. On Android 10 or 11, tap Wi-Fi. On Android 12, you’ll need to select Internet instead.

You’ll then see your current Wi-Fi network at the top of the list. Select it to viewoptions for the network. If you’re not connected to the right network, select another one from the list; check the Saved networks entry at the bottom of the page to easily find past connections.

On the Wi-Fi network’s overview page, select the Share button. You’ll need to confirm your face/fingerprint, or enter your PIN code, to proceed. Once you do, you’ll see your network’s Wi-Fi password listed below a QR code.

You can now tell someone else your network’s Wi-Fi password or enter it on a different device because you are aware of it.

Since another device can connect to the network without having to manually enter the password, the QR code displayed on this page makes the process even more convenient. By hiding the actual password, this improves network security and eliminates the frustration of entering the password incorrectly.

If you’re sharing the password with an Android device, that other device can tap the QRCode icon next to Add network (below the list of Wi-Fi networks) to easily scan and join. If the other person has an iPhone, have them scan the code using the Camera app, then tap the prompt to join. See how to scan QR codes on Android and iPhone if you have trouble.

Starting with Android 12, you’ll also see a Nearby button that lets you share the password with otherAndroid devices around you. This uses the Nearby Share function, and saves the step of having to scan the QR code from your device’s screen.

For convenience, you may want to screenshot the QR code so you can send it to others without going through the above menus every time. Just remember that anyone with that code can join your Wi-FI network, so keep that picture safe.

How to See Wi-Fi Passwords on Android 9 and Older

You’ll need to use alternative methods if you’re using Android versions 9 or earlier or if the aforementioned option isn’t available on your phone for some other reason. A rooted Android device is necessary for all of these techniques, which is unfortunate.

This is so that your phone can store the file that contains the Wi-Fi login information for saved networks in a protected directory. Except for those who are rooted, you lack the rights to view the folder or the file inside.

If you have a rooted device and want to see your Wi-Fi password on Android, you can head to /data/misc/wifi using a file explorer app that supports root browsing. Open wpa_supplicant.conf and you should see your network name (ssid) and its password(psk).

Use an Android Wi-Fi password viewer app like WiFi Password Viewer if this doesn’t work or you want to try another approach. To view the password, you can pick one of your saved networks using these.

They require root, and have mixed reviews, so your mileage may vary. If your phone encrypts the file containing Wi-Fi passwords, there isn’tmuch apps like this can do.

View Wi-Fi Passwords on Another Device

These are the two primary ways to view Wi-Fi passwords that have been saved on Android. Your best option is to check the Wi-Fi password on a desktop computer if you’re not rooted and use Android 9 or earlier. These greatly simplify things; for assistance, see how to view Wi-Fi passwords on a Mac or how to find Wi-Fi passwords in Windows 10.

In the future, consider using a password manager so you have your own record of important Wi-Fi passwords and don’t need to use these workaround methods You should also make sure your own Wi-Fi network is protected against attack

How can I get my friends Wi-Fi password on my phone? : If your guest has an Android phone, head to Settings, Connections (or Network and Internet), then Wi-Fi on their phone Scroll down to find where it says Add Network; next to it, you’ll see a QR code icon Tap on it and they can now quickly scan the code Scanning the code should automatically connect the device
