Today we have decided to show How Hackers hack wifi Passwords in just Minutes
What is Wifi? and Why do people go nuts overs it?
WIFI is a technology that allows electronic devices to connect to a wireless LAN (WLAN).The Wi-Fi Alliance defines Wi-Fi as any “wireless local area network” (WLAN) product based on the Institute of Electrical and Electronics Engineers’ (IEEE) 802.11 standards. A WLAN is usually password protected, but may be open, which allows any device within its range to access the resources of the WLAN network.
How easy is to hack WIFI?
Wi-Fi is less secure than wired connections, such as Ethernet, precisely because an intruder does not need a physical connection. Web pages that use TLS are secure, but unencrypted Internet access can easily be detected by intruders. Because of this, Wi-Fi has adopted various encryption technologies.
Before that we need to know some basic Terminology
AccessPoint (AP): a wireless access point (WAP) is a networking hardware device that allows a Wi-Fi compliant device to connect to a wired network.
Network :a group or system of interconnected people or things
channels:Choosing the best Wi-Fi channel on your router helps to reduce interference and improve your WI-Fi signal
Packets:- A network packet is a formatted unit of data carried by a packet-switched network. Computer communications links that do not support packets, such as traditional point-to-point telecommunications links, simply transmit data as a bit stream
To Hack we will be using the Tool called Airmon-ng. Airmon-ng works best on linux computers. so i would be using Kali-linux in which Airmon-ng Tool is pre-installed.
- hit Ctrl+alt+t to open new terminal in your Linux Machine.
- The user you have logged in must be a Sudo user or you need to be an root. type the command su if you know the root password. or type sudo -i to become root as and sudo user.
- Type the Command “Ifconfig” and check your Network Adapters there might be 3 a.Your localhost lo b.Ethernet Adapter c.Wifi Adapter. If you don’t see your Wifi Adapter you need to Turn on your Wifi.The Name of the Adapter might be Different in depending on your Linux distro. In Kali linux the Wifi Adapter is named as wlan0. As you can see wifi is turned on but not connected Because we Don’t know the Password
- We need to Set the wifi Adapter in “Monitor Mode” monitor all traffic received from the wireless network. Unlike promiscuous mode, which is also used for packet sniffing, monitor mode allows packets to be captured without having to associate with an access point type the following command to set the Wifi Adapter to the Monitor Mode.
airmon-ng start wlan0
- We have successfully set our wifi Adapter in the Monitor Mode from now our Adapter name as been change to wlan0 to wlan0mon.
Now we will use Airodump-ng to capture all the Packets on rouge. Basically our Wifi Adapter does not filter Packets it captures all the Packets
- Wait for 5 Minutes untill you see your Victim’s AccessPoint that is wifi Netowrk. Here for the demonstration purpose we will hack our won wifi “JayRyan” run for 5 minutes and stop it by pressing ctrl+c
- we will now drop the rouge packets and only concentrate on the Victim AccessPoing Note Down the bssid and channel no of your Victim’s AP. For eg:- 6C:72:20:F8:0F:1E is the bssid and channel no is 10.
- Type the Following command to capture only from your Victim AP. “Airodump-ng wlan0mon –bssid 6C:72:20:F8:0F:1E -c 10 -w / “The location where you need to dump the Captures Packets”
- Instead of Capturing all the Packets on the Monitor Mode now we are only dumping the Victim Traffic to your desired location prefixed by -w. This folder contains .cap file which we are going to crack if we can capture the password. Here comes the tuff part we should either wait till we get a Handshake or Force deauth an user who is using wifi and capture handshake. Type the Following command to Deauth an user “Aireplay-ng -o o -a “your bssid” -c “station essid”
- To capture the Password of the wifi we will force an user to authenticate. by sending the deauth packets to the client device it might be a phone,laptop or pc. Modern laptops and computers needs more packet to authenicate. Keep sending the deauth packets to a weak device untill you get the Handshake.
- If you can’t make the device to Authenticate. or you don’t capture the handshake then send Deauth packets directly to the router. then expect any of those device to authenticate again.
- WPA Handshake can be found on top right. Congratulation now you go the Password on your cap file. All you have to do now is crack the password. If you don’t get the Handshake Bad luck..:( You should get the Handshake if your following the instruction.(Don’t cancel the capturing process of vitctim packets in the background) Find another way to Hack There are so many ways to Hack a wifi best one is caffe latte. 01.cap file contains the password captured ie handshake we can open it in wireshark to check our deauth packets.
- Final step we need to crack the Password type the following command to crack “aircrak-ng “location to your 01.cap file” -w “location to your wordlist file”
Yes, we found the password. Missed any steps finding difficulty on any steps feel free to comment we would help you learn something. 🙂
