How to hack into any Wi-Fi network in front of you and know your password |
Wi-Fi is a wireless network that connects all the devices in which they are located, but one of the drawbacks of it is that it is more vulnerable to penetration than wired networks.
So we will try to provide you today hopefully, many ways used by hackers in order to penetrate this type of networkand the measures taken to repel these types of attacks.
Unencrypted Wi-Fi network hack:
This type of network is not protected by passwords and is available to everyone, the hacker can access it and spy on the computers in them and know a lot of sensitive information.
This process is carried out using an attack technology known as man in the middle attack and its shorthand MIM using one of the most famous programs in it, wireshark, which has been released in both Linux and Windows operating system.
In the unencrypted Wi-Fi network, traffic is not protected and the hacker can pick up and analyze all the packets of the HTTP protocol and then extract all the information in it, but it cannot do the same with https packets because they are highly protected.
Hack hidden Wi-Fi network:
The hacker can hack into your Wi-Fi network using some programs that help show hidden networks, including kismet in Kali Lennox and inSSIDer in Windows, which provides him with many information such as the name of the hidden network SSID and its type and the wireless channel used in the channel communication and signal power, hence it will create a fake Wi-Fi network that has the same properties as your hidden network in an attempt to drag your computer or smartphone to connect to it, that's because of the nature of the network Calculators automatically connect to this type of hidden network slot every time.
And with this fake network, he's going to hack the entire network and get everything he wants.
Hack wi-fi network by changing the Mac Address:
When the hacker uses some network analysis tools, he will also get the Mac address for all the devices in it, which will use one of them in an attempt to camouflage the router router and convince him that it is one of the devices that used to communicate with it.
This process is called Pal Mac spoofing which is a change of mac address in the attacker's device using the tool known in Cali Lennox which is macchanger and replace it with one of the devices belonging to the network and then wait to disconnect the network by the client or make itself an attack called deAuth Attack which forces the device to disconnect and then connect to the wi-fi network.
Hack wi-fi network by breaking encryption protection:
One of the most popular encryption systems used to protect passwords for Wi-Fi networks is WEP, WPA and WPA2, and in order for a hacker to hack into your wireless network, he must break password encryption using many tools.
Decryption of WEP is fairly easy, because this system is not very secure and can be skipped by the aircrack-ng tool located in Kali Lennox and can also be installed in Windows and the more packages obtained when analyzing the network the more easy the process of obtaining the password.
This is an illustration of the wi-fi network hack:
As for decrypting WPA and WPA2, it is rather difficult because it is a very powerful protection system and can only be broken by using the Brute-Force attack along with the Dictionary attack.
This process is done after the hacker monitors the handshake packets that are exchanged when the device connects to the access point, and these information can be obtained by deAuth Attack for a computer connected to the network and then the hacker uses the Brute-Force attack along with the dictionary attack to verify the password in a text file expressed by Wordlist, and if the handshake is successfully made, it means that the password has been found.
Hack wi-fi network via WPS loophole:
By exploiting the gaps in router settings, particularly the activation of WPS, the hacker can hack into your Wi-Fi network by using the Brute force to guess the eight numbers that are the password for WPS and are at the same time considered an alternative to the network password.
One of the tools used in this attack is the Reaver tool in Cali Lennox.
Note:
It is possible to obtain the encrypted password with WEP and WPA in a short period of time ranging from some hours to two days at the latest, but for WPA2 it cannot be identified and can last 🙂 years depending on the combination of characters, numbers and symbols in addition to the length and power of the computer processor or screen card processor.
Ways to protect the Wi-Fi network:
To protect your wireless network there are many measures that we recommend to take as follows:
Don't use a hidden Wi-Fi network.
Select Mac address devices that allow them to connect to your network.
Use WPA2 encryption and make sure you put a strong password made up of numbers, letters and symbols.
Do not do WPS on the router.
Make sure you change your password from time to time.
We hope that we have succeeded in raising this topic in most of its aspects, and we advise you if you are interested in the field of information security and penetration to use the tools in the operating system Calle Lennox, which are integrated and effective.
[Wi-Fi Information]
Comparison of Wi-Fi and Bluetooth:
Both are technical terms for forms of radio communication that rely on radio waves for transport.
Bluetooth technology falls within the IEEE802.15.1 protocol while wifi is within 802.11 this means that devices using wifi technology cannot necessarily use Bluetooth.
Wifi technology has great data transfer speeds making it a good alternative to ethernet networks, while Bluetooth technology needs less power, so it stands out more in small devices such as pda.
The difference between them in the covered area is much lower than Wi-Fi. The actual area covered by Bluetooth is between 7 meters and 10 meters while it is approximately 60 meters in Wi-Fi.
Wifi:
Wi-Fi networks were invented and developed to serve communications within the lan local worknetwork but without the use of wires.
At first, its aim was to serve laptops, but with the rapid development of this technology, it became a service for the surfers of the world, especially in cafes, restaurants, hotels, airports and banks.
It now plays an important role in VoIP technology, and is now performing a large service in sensitive locations such as hospitals and security sites so that the doctor or security man can access certain applications to serve patients or identify undesirable persons from entering sensitive places and others.
Wi-Fi networks have added a lot to mobile technology and universal Internet connectivity if you are within wi-fi. A modern and important use is to transfer images from digital cameras to computers.
How to use Wi-Fi networks:
First, the computer used must be equipped to connect to wi-fi "supports wifi", and it should be noted that most mobile devices now sold are equipped with Wi-Fi cards inside them and are also designed to be integrated with the hotspots that provide this service.
If it is not, the computer can also be configured using an adapter that is connected via a USB or PCI SLOT portal.
Connecting to the Internet via Wi-Fi:
Wi-Fi connectivity is very easy, as the software that comes with the wireless card automatically searches the area around it for a hotspot, if you find it can connect to the Internet with ease.
