How to Hack an Android Wi-Fi Password

This article will help you if you want to learn more and want to know how to hack the Wi-Fi password using an Android device. A lot of people want to know if and how they can hack Wi-Fi passwords with an Android phone. The simple answer is "yes," you can hack Android Wi-Fi passwords with the right tricks and tools (apps).

Before we get into our main topic, which is how to hack Wi-Fi passwords on Android phones, we'll talk about some basics of how Wi-Fi password security works.

What Kinds of Wi-Fi Passwords Are There?

There are mainly three kinds of Wi-Fi security passwords. Here are these Wi-Fi safety measures:

  1. Privacy Like Being Wired (WEP).
  2. Wi-Fi Protected Access (WPA) (WPA).
  3. Wi-Fi Secure Setup (WPS).
  4. Privacy Like Being Wired (WEP)
  5. Privacy Like Being Wired (WEP)

Wi-Fi security is one of the most popular and widely used security measures for Wi-Fi networks all over the world. But this security is very weak and not very safe at all. With Airman tools from Kali Linux and Aircrack, it's easy for someone to break into and hack such Wi-Fi security.

  • Wi-Fi Protected Access (WPA) 
  • Wi-Fi Protected Access (WPA) 

WEP Wi-Fi security system has been improved and updated to become Wi-Fi security. In 2003, this Wi-Fi security system was put on the market. But an American hacker found a major problem with the way WPA security keys work. Because of this, hacking this Wi-Fi security became easy. Any WPA-protected Wi-Fi password can be broken using an Android smartphone.

  • Wi-Fi Secure Setup (WPS)

Last but not least, the Wi-Fi Protected Setup (WPS) is the only Wi-Fi security system that is hard to hack. But it has been found that this Wi-Fi security can also be broken, but it takes a lot of skill to do so. If someone uses WPS security, it might be hard to get around it.

Method 1: Using WIFI WPS WPA TESTER to hack a Wi-Fi password on an Android device (Without Rooting)

Wi-Fi WPS WPA TESTER is a popular Android app that is often used to hack Wi-Fi passwords. The Wi-Fi WPS TESTER app can only hack routers that connect with WPS routers that have limited features. Using this app to hack Wi-Fi is easy and only requires a few steps. The best thing about this app is that you don't have to root your Android phone to use it. You can also use this app with some extra features on an Android phone that has been "rooted."

With this Android app, it's easy to check your router's wireless security and strength. If the router isn't secure, the WIFI WPS WPA TESTER app on your Android phone makes it easy to get around the Wi-Fi password. It connects the Android phone to the router without asking for a password after you skip the password screen.

 Hack an Android Wi-Fi Password

Both rooted and unrooted Android phones can use the Wi-Fi WPS WPA TESTER hacking apps. Here are the steps to hack a Wi-Fi password on an Android device without having to root it.

  • From Play Store, get the WIFI WPS WPA TESTER app and install it.
  • On your Android phone, turn on the Wi-Fi settings.
  • Start the app and look for nearby Wi-Fi networks.
  • Choose one of the networks from the list and start tapping to hack it.
  • You can type in its key by hand.

The app checks the security of the Wi-Fi network and tries different combinations of words and numbers to figure out the password. The app quickly finds the network code and automatically connects your phone.

Method 2: Hacking an Android Wi-Fi password with the AndroDumper App APK (Without Rooting)

AndroDumper is another well-known app used to hack Android phones' Wi-Fi passwords. This app can be used to hack Wi-Fi passwords on a device that hasn't been rooted. Follow the steps below to use this app to hack Wi-Fi passwords on Android.

  • You can get the AndroDumper app for your Android phone and install it.
  •  Hack an Android Wi-Fi Password
  • The Wi-Fi settings on your Android device need to be turned on.
  • Open the AndroDumper app and click the "Refresh" button at the top of the screen to search for and find Wi-Fi networks in the area.
  • Pick the network you want to hack, connect to it, and tap on it.
  • Now, the app will try to connect to the network you chose using every possible letter and number password combination. If the chosen Wi-Fi network has a weak password, this app could break into it.

Method 3: Hacking a WPA2 WPS router with an Android phone (Root device)

We'll use the Bcmon and Reaver Android apps to hack Wi-Fi passwords on Android in this way. First, you need an Android phone that has been rooted, if you haven't already. Make sure your rooted Android phone has the same Broadcom bcm4329 or bcm4330 chipsets as the Samsung Galaxy S1/S2, HTC Desire HD, Nexus 7, Nexus 1, etc.

 Hack an Android Wi-Fi Password

  1. You can get the APK file for the BCmon app and install it on your Android phone. This app lets you keep an eye on your Broadcom chipset and figure out your PIN.
  2. Now, get the Reaver app for Android and install it to figure out and break the WPS Wi-Fi network password.
  3. After installing the app, open the BCmon app and tap on "monitor mode."
  4. Again, open the Reaver app and make sure on the screen that you are not doing anything wrong by using it. Tap on the APN or access point whose password you want to break, and then tap "Continue." Sometimes, to keep going, you need to check your monitor mode, which you can do by opening the BCmon app again.
  5. Go to the app's settings and check the box next to "Automatic Advanced setting."
  6. Lastly, click "start attack" to start the Wi-Fi cracking process. In this last step, cracking the WPS Wi-Fi security could take anywhere from 2 to 10 hours.

Method 4: Using the Wi-Fi WPS Connect app on an Android device to hack a Wi-Fi password (Root device)

Using the Wi-Fi WPS Connect app, Android users can hack Wi-Fi passwords. The app works on phones with and without root access (Lollipop and later). But because of the database information, it is mostly used on devices that have been "rooted."

If you find a WPS-secured Wi-Fi network on your Android device, you can connect to it without having to enter a password. The WPS Connect app gets around the security of WPS Wi-Fi and connects to Wi-Fi without a password.

 Hack an Android Wi-Fi Password

Here are the steps to use this app to hack a Wi-Fi password and connect your Android phone:

  • Get the Wi-Fi WPS Connect app and put it on your Android phone.
  • On your phone, turn on the Wi-Fi settings.
  • Open the WPS Connect app and tap the scan button to find all Wi-Fi networks in the area.
  • It only takes a few clicks to show all the nearby Wi-Fi networks and their information (such as password security types, network types, signal strength, etc.).
  • Choose a Wi-Fi network you want to hack and tap on it. A screen pops up with a list of keys that have already been set (PIN).
  • Start hacking by tapping on the key.
  • The app tries to hack Wi-Fi several times using the default keys and the most common Wi-Fi keys.
  • If you wait a few minutes, the Wi-Fi password will be broken.

Method 5: Hacking an Android Wi-Fi password with the WPSAPP

WPSAPP is an all-in-one app that lets you use an 8-digit PIN to connect to nearby Wi-Fi networks. The WPSAPP app makes hacking Wi-Fi passwords easier and more convenient on both rooted and unrooted Android phones. Several algorithms are used to make random pins, and some pins are set as defaults. If you have this app, you can easily hack into any WEP Wi-Fi network.

When you look for networks, the red cross, question marks, and green tick marks show up next to them. The networks used by the Red Cross are safe, and no one knows what their password is. The networks with question marks have WPS protocol turned on, but their pins are unknown. The app lets you test them with a common pin to see if they work. Lastly, the networks with green ticks have the WPS protocol turned on and their passwords are known, so you can connect to them.

Here are the steps you need to take to use this app to hack Wi-Fi passwords on an Android phone.

  • You can get the WPSAPP app for your Android phone and install it.
  • Now, open the app and it will look for Wi-Fi networks in your area.
  • Click on the WEP network you want to connect to that is turned on.

When you click the "CONNECT WITH PIN" button, the app shows your network password after a few seconds.

How to Hack WiFi Password: A Guide to Cracking Wi-Fi Network

Wireless networks can be used by anyone within the range of the router. Because of this, they are easy to attack. You can find hotspots in public places like airports, restaurants, parks, and so on.

In this tutorial, we'll show you some common ways that security flaws in wireless networks are taken advantage of. We will also talk about some things you can do to protect yourself from these kinds of attacks.

This How to Hack WiFi Tutorial talks about the following:

  • How do wireless networks work?
  • How do you connect to a wireless network?
  • WEP and WPA Authentication of Wireless Networks
  • How to Break Wireless (WiFi) Networks
  • How to keep wireless networks safe.
  • How to break into a WiFi password
  • How do wireless networks work?

Radio waves are used to connect computers and other devices on a wireless network. Layer 1 (the physical layer) of the OSI model is where the implementation happens.

How do you connect to a wireless network?

You will need something that can connect to a wireless network, like a laptop, tablet, smartphone, etc. You will also need to be in the area where a wireless network access point sends signals. If the wireless network option is turned on, most devices will show you a list of networks that you can connect to. If the network doesn't need a password, all you have to do is click "Connect." If it has a password, you will need to know the password to get in.

Authentication of a Wireless Network

Most networks require a password because anyone with a device that can connect to a wireless network can easily use it. Let's look at some of the most common ways to make sure someone is who they say they are.

WEB

Wired Equivalent Privacy is what WEP stands for. It was made to meet IEEE 802.11 standards for WLAN. Its goal was to give users the same level of privacy as wired networks. WEP works by encrypting the information being sent over the network so that it can't be listened to.

Authentication with WEP

Open System Authentication (OSA): This method gives access to stations that request authentication based on the access policy that has been set up.

Shared Key Authentication (SKA): This method sends an encrypted challenge to the station asking for access. The station uses its key to encrypt the challenge and then gives its answer. If the value of the AP matches the value of the encrypted challenge, access is given.

Weakness of WEP

WEP was made with major flaws and security holes.

Cyclic Redundancy Check is used to make sure that the packets are still good (CRC32). At least two packets can be used to break the CRC32 integrity check. The attacker can change the bits in the encrypted stream and the checksum so that the authentication system will still accept the packet. This lets people get into the network without permission.

WEP makes stream ciphers with the RC4 encryption algorithm. The input to a stream cipher is made up of a secret key and an initial value (IV). The initial value (IV) is 24 bits long, while the length of the secret key can be either 40 bits or 104 bits. Both the initial value and the secret can be as long as 64 bits or 128 bits. Because the secret key can only have a low value, it is easy to figure out.
Combinations of weak initial values don't encrypt well enough. Because of this, they are easy to attack.
WEP is based on passwords, so it can be broken with a dictionary.
Management of keys is not done well. It is hard to change keys, especially on large networks. WEP does not have a central system for managing keys.
The first values can be used again.
WEP has been phased out in favor of WPA because of these security flaws.

WPA

Wi-Fi Protected Access is what WPA stands for. It is a security protocol that was made by the Wi-Fi Alliance to fix the problems with WEP. On 802.11 WLANs, it is used to encrypt data. It uses 48-bit Initial Values instead of WEP's 24-bit Initial Values. It encrypts packets with keys that change over time.

WPA Weaknesses

  • The code for avoiding collisions can be broken.
  • It can be hurt by attacks that stop it from working.
  • Passphrases are used with pre-shared keys. Dictionary attacks can get through weak passphrases.
  • How to Break Wireless (WiFi) Networks

WEP was broken.

Cracking is the process of taking advantage of security holes in wireless networks to get in without permission. WEP cracking is the term for attacks on networks that use WEP to protect themselves. There are two main kinds of cracks, which are;

Passive cracking: This kind of cracking doesn't affect network traffic until the WEP security has been broken. It is hard to find out.
Active cracking is a type of attack that makes the network traffic load up more. When compared to passive cracking, it is easy to spot. Passive cracking doesn't work as well as this method.

Tools for WiFi Password Hacking (WEP Cracking)

Aircrack is a WEP cracker and a network sniffer. This WiFi password hacker tool can be downloaded from http://www.aircrack-ng.org/WEPCrack. WEPCrack is an open-source Wi-Fi hacker program for breaking 802.11 WEP secret keys. The FMS attack is built into this WiFi hacker app for PC. Kismet (http://wepcrack.sourceforge.net/) is an online WiFi password hacker that can find both visible and hidden wireless networks, sniffer packets, and find intrusions. This WiFi password hacking tool, WebDecrypt (https://www.kismetwireless.net/), uses active dictionary attacks to break WEP keys. It can hack WiFi passwords because it has its key generator and packet filters. WPA Cracking can be found at http://wepdecrypt.sourceforge.net/

WPA authenticates users with a 256-bit pre-shared key or passphrase. Dictionary attacks and other attacks that can be used to crack passwords can be used to break short passphrases. WPA keys can be broken with the following online WiFi hacker tools.

CowPatty is a WiFi password cracker tool that uses a brute force attack to break pre-shared keys (PSK). 
Cain and Abel: This WiFi hacker for PC can be used to decode files that other sniffing programs like Wireshark have captured. The frames in the capture files may be encoded with WEP or WPA-PSK. https://www.softpedia.com/
Types of Attacks in General

Sniffing is the process of catching packets as they move across a network. Then, tools like Cain & Abel can be used to figure out what the data means.
The Man in the Middle (MITM) attack is when someone listens in on a network and steals private information.
The main goal of a Denial of Service Attack is to keep real users from using network resources. You can use FataJack to do this kind of attack. Find out more about this in the article Cracking WEP/WPA keys for wireless networks

The WEP/WPA keys used to get into a wireless network can be broken. To do this, you need software and hardware tools, as well as time. Hacking WiFi passwords can also work better or worse depending on how active or inactive the users of the target network are.

We will tell you some basic things that will help you get started. Backtrack is a secure operating system that is based on Linux. On top of Ubuntu, it is built. Backtrack has a lot of security tools built in. Backtrack can be used to do a lot of different things, like gather information, check for weaknesses, and do exploits.

Backtrack has several popular tools, such as;

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

To crack wireless network keys, you need to be patient and use the tools listed above. At the very least, you will need the following:

A wireless network adapter that can put packets into the network (Hardware)

Kali Operating System. You can get it at https://www.kali.org/get-kali/.

Be within the range of the target network. If the target network's users are actively using it and connecting to it, your chances of breaking into it will be much better.
You should know enough about Linux-based operating systems and how to use Aircrack and its different scripts.
Be patient, because getting the keys may take a while, depending on several things, some of which you may not be able to change. People using the target network while you sniff data packets is an example of something you can't control.
How to keep wireless networks safe.

A company can use the following policies to reduce the number of attacks on its wireless network:

Changing the passwords that come with the equipment by default
Turning on the authentication system
Only MAC addresses that have been registered can be given access to the network.
If you use strong WEP and WPA-PSK keys with a mix of symbols, numbers, and letters, it will be harder for dictionary and brute force attacks to break them.
Firewall software can also help stop people from getting in without permission.
