With the advances of recent years, knowing how to hack the key of a Wi-Fi network has become accessible to many people. The tools advance. Also, devices such as smartphones make it increasingly easy for us to decipher those keys that prevent access to any wireless network of the millions worldwide.
You want to learn how to do it, so here we leave you with a complete guide. We will explain when you can hack Wi-Fi passwords, how you can do it, and what tools, both on PC, Android, and iPhone. Everything you need to know, explained step by step and in great detail.
Why hack a Wi-Fi password
Although it may seem like not, there are many reasons why a person might want to hack into a Wi-Fi network. Although nowadays it is rare not to have an internet connection thanks to data rates, there may be cases where it is urgent to connect, and there is no way to do so.
Imagine, for example, and you have to make an urgent delivery of a job by e-mail and, suddenly, you find yourself in a place where you do not have a connection. Still, you come across many password-protected wireless networks.
It can also happen that you are in a place and have a long wait ahead of you. In that case, you may want to kill a little time by diving through the network of networks, consulting your profiles on social networks, or simply chatting. In that case, you may also find it helpful to know how to hack Wi-Fi networks to access those that are behind a wall shielded by a password.
One last reason, although it does not have to be the least important, is device updates. Some, the moment they detect a new version on the way for their software, they block and prevent any use. In these circumstances, having access to a wireless network to perform the relevant update is paramount.
It would also be interesting for you to know how to hack networks to access, download, and update your gadgets, not to give problems.
Can I hack any wireless network?
Although we have seen several scenarios in which there are plenty of reasons to hack WiFi networks, you should know that you cannot access all of them. The first and most important thing is that you need the consent of its owner to be able to do it since, otherwise, you can face a penalty that translates into an economic sanction or, as happens in some countries, even in jail.
The law is not very friendly to these acts of hacking without consent, so you must take it into account when entering any foreign WiFi network.
On the other hand, if you want to proceed with the hacking from both Android and iPhone mobile phones, as we will explain later, you must be very clear about one thing: its ability to decipher network passwords is minimal. The method that is generally followed for this purpose is brute force, with the device sending thousands of password proposals following certain patterns until it hits the key. That can translate into a good handful of hours of work.
Smartphones do not have enough power or capacity to deal with something like this, so their range of action is much more limited. Even so, you should know that some networks can be hacked, but they must meet quite specific requirements and, above all, not enjoy powerful protection. If so, you will need a laptop or desktop PC, advanced tools, and, above all, a lot of patience.
When can I not hack a network?
We have already advanced it previously, but we will remember it in order not to leave any hint of doubt. It would help if you did not hack wireless networks without the consent of their owner. You can, for example, hack yours if you have modified the password, have forgotten it, and cannot connect; you can, in fact, even hack the odd one to test its security measures and show if it is as safe as you think or not. You cannot take advantage of the hacking tools and knowledge to save you the payment of the internet connection, as long as it is without permission.
The law does not allow such uses and seriously persecutes those who carry them out. Be careful if you will experiment with hacking passwords for wireless networks; you must move with a lot of head and, above all, with permission.
How to Hack WiFi Password 2021? | Wifi Hack With Andriod Phone
Knowing all the critical pre-considerations, it is time to address the crux of the matter. You want to know how to hack WiFi password, and we are going to explain how you can do it both on PC, Android, and iPhone, although being very aware of the limitations of these last two options.
You should know that most of the tools to carry out this process are accessible. Therefore, you will not have to worry about paying anything. Also, if you can opt for the option of using a computer, do so, since it is the one that will give you the best results.
Decrypt WiFi keys on PC
Cracking WiFi passwords on a PC is currently the most successful method of obtaining keys. Before starting to explain the steps you have to follow, you should know something very important, and that is that you cannot use the Windows operating system if you want to hack networks.
You will have to use a particular Linux distribution, although you don’tdon’t even have to install it. You have to copy it to a USB memory and boot from it when you turn on the PC. The rest are a few more complex steps.
Here we are going to explain everything you have to do to decrypt WiFi passwords with your computer :
- Make sure you have a robust wireless card and download the Kali Linux distribution. When you have it, please insert it into a USB memory.
- Access the BIOS of your PC by pressing a specific key at power-up and change the boot so that it begins by reading the USB memory first. Reboot.
- With the memory inserted in the USB port, turn the PC back on and let it load the Linux operating system.
- Once inside, open a terminal and type the command “airmon-ng” to verify that your wireless card is compatible.
- After this, kill all unnecessary processes that might interfere by typing “airmong-ng check kill.”
- It is time to activate the monitor mode for your WiFi card. In the same command window, enter “airmon-ng start wlan0”, where the number of your primary adapter is zero.
- When activated, it’s time to start “listening” to the networks. Enter the command “airodump-ng wlan0mon”. If your card had the interface name “wlan1” or with another number, something that you can see in the “Interface” section that appears when performing step 6, replace it with the “wlan0” of the command that we just gave you. Give.
- Now you will see a large number of letters and numbers. You have to search for the network you want to hack, whose name will appear under the “ESSID” column. When you find her, write down her “BSSID” and her “CH.”
- When you have everything pointed, write the following command “airodump-ng – [CH] –bssid [BSSID] –write [File name] wlan0mon”. Remember that in the sites that we have marked as [CH] and [BSSID], the data indicated in the previous point must go. In [File name], you must write the name of the file where you want the transferred packages to be saved.
- While that window is working, open another terminal. We are going to disconnect the rest of the clients connected to the network. It can raise suspicions if it is being used, but necessary to speed up the process).
- In your new terminal window, enter the following command: “aireplay-ng -0 10 -a [BSSID] -e [ESSID] wlan0mon”. Remember that the annotated data must go in the fields between brackets and that wlan0mon depends on point 6.
- When this process is finished, and the “handshake” is achieved (the connection is established), it is time to find the key.
- Enter this command: “aircrack-ng [File name] -w [Dictionary]”. In [File name], you must write the full name of the file created in point 9, usually with the extension “.cap.” In [Dictionary] will go the name of the file with the Dictionary to decrypt. Search the tool data to find it, and it has the extension “.txt.”
- Now let it work. The process can take from a few minutes to a few hours, depending on the security index of the key.
- When finished, a message will appear with the text “KEY FOUND!” and, next to it, the password.
While using brute force and can take its time, this system is capable of cracking passwords ranging from old WEP to robust WPA2-AES. It is rare when it fails, although it may take more than a day in the most challenging circumstances.
Hack Wi-Fi passwords on Android
There are several important factors when it comes to Android Wi-Fi key hacking. The base of this operating system is Unix, the same as Linux, which gives it a plus when hacking passwords. To achieve a good result, the network has to respond to very specific characteristics, and so does your phone.
In this sense, the best tool is called Bcmon, although it requires that you have RootRoot installed on your terminal and that it has a Broadcom BCM4329 or 4330 chip. If not, you will have to resort to other, much less capable options.
If you meet the conditions, then we are going to give you the steps to follow to hack Wi-Fi networks on Android:
- Download and install the Bcmon app on your Android phone. Remember to give permissions to install applications of unknown origin to avoid problems.
- Also, download the Reaver application. It is essential to bypass the security system and obtain the password.
- When you have both, open Bcmon and activate monitor mode through the option that allows it.
- After activating and without closing the app, open Reaver, confirm that you will not use it for illegal purposes, and then tap on the name of the access point or Wi-Fi network you want to hack. After that, click “Continue” again to continue. If something goes wrong, take a look at Bcmon and check that you have enabled monitor mode fine.
- Back in Reaver, check the “Advanced Automatic Configuration” option to activate the appropriate parameters to decrypt the key automatically.
- After that, press the button to start the attack. Now, let your mobile start working.
- Hopefully, in less than 10 hours, you will have the password to access the network.
As we said before, particular conditions must be met for this method to work since mobile phones are not designed for this type of task. Although Android is something more possible thanks to its operating system, you have already seen the demands regarding the chip.
If you don’t meet that requirement, you have other tools available, but they usually only work for old networks with WEP keys or even those that have never been modified, thanks to dictionaries. In these cases, brute force is not used, so the success rate is much lower.
ANDRODUMPER APP, THE OTHER OPTION WITHOUT ROOT
In case you don’t want to “root” your Android mobile, the AndroDumper application is one of the best out there. Its handling is very simple since you only have to download it, install it in the terminal and press a couple of buttons to make it work (“Update” to see the networks, choose the one you want to hack and, finally, click on “Test connection”).
It does not always manage to crack passwords, but of all the options for users who do not have the specific chips or do not want RootRoot, it is the best currently available.
Hack Wi-Fi with iPhone
If you have a jailbroken iPhone, then you can have access to the most powerful app for hacking Wi-Fi networks, Wifi2Me. It is a free tool that allows you to crack the password of many of today’s wireless networks, although it may take time. It is used primarily to check the security of Wi-Fi and see if they are safe.
If you do not have Jailbreak, you will not be able to use it, and you will lose all its potential since the tools that will be available then are not even half as capable as this one.
Do you meet that condition? In that case, we are going to give you the steps to follow to hack a Wi-Fi network with iPhone :
- Download and install the Wifi2Me application for your iPhone phone (it also works on iPad).
- Open the app once it has been installed and, as soon as you start, you will run into several options.
- Start by choosing the “Networks” button to view nearby networks. Please select the one you want to hack, as long as it is listed as compatible.
- Now let it work. You will see a progress bar that shows the evolution of the process.
- When finished, the password will appear on the screen. Copy it.
- You can now use it to connect.
You must bear in mind that, although the process is very simple, not all networks or routers are compatible with this program. It is currently the most powerful for the iPhone, but it has many limitations that prevent it from approaching the performance and results of PC tools.
Can I hack a Wi-Fi network without a password?
Although it is not the most common, there are some pretty simple methods to hack Wi-Fi networks without a password since there are some powerful tools. It must also be said that it is not the most practical method, nor the one that yields the best results, but it can be done, even if it involves having direct contact with the router in question, to weaken its security even more.
If you can approach the router when hacking, you have to press the WPS button so that, taking advantage of that moment, any of your devices connect. Some apps take advantage of this weakness to access the moment or that even force the device to activate this option to open its doors.
Another option, much more manual and laborious, is to reset the router by inserting a thin element in the slot for it. By doing that, it resets its factory settings and changes your Wi-Fi passkey to a much simpler and more standard one. Sometimes it can be something as simple as “00000000” or a similar alphanumeric sequence. If you have free hacking apps, now you can take advantage of them.
In short, it is possible to hack a Wi-Fi without having to find out keys, but it is not the most comfortable way, nor the most practical, nor the most effective.
