In areas such as airports, restaurants, etc hotspots are available. Here we will tell you about the common techniques that can be used to exploit weaknesses in the security implementations of WiFi networks. Also, we will talk about some measures to counter these breaches of WiFi access and protect your network from attacks.
To access a wireless network, you will need a wireless network-enabled device like a laptop, tablet, smartphone, etc. Also, you need to stay within the radius of transmission or range of the wireless network access point. If the WiFi option is turned on, most devices will give you the list of the available networks. The networks which are not protected by a password can be accessed just by clicking. If the network has a password, then you have to find the password to access it.
You can exploit the weaknesses in wireless networks and gain unallowed access to the network. This is called cracking. Cracking wireless networks can be done, majorly, in two ways:. Passive cracking— This is quite difficult to detect. It has no effect on the traffic of the network til the WEP security has been cracked. Active cracking— This increases the load on the traffic. Compared to passive cracking, this can be easily detected. It is also more effective than passive cracking.
Aircrack — This is a network sniffer and a WEP cracker. FMS attack is implemented through this. Kismet - It detects the wireless networks which are visible as well as the hidden, sniffer packets and also detects intrusions.
It has key generators of its own and it implements packet filters for hacking WiFi passwords. For authentications, WPA uses a pre-shared key or passphrase. Mostly, if short passphrases are used, they become vulnerable to dictionary attacks. The mentioned Wifi hacker tools can be used to crack the WPA keys. Sniffing — Sniffing involves the intercepting of packets as they are transmitted over a network. Then the captured data is decoded using tools such as Cain and Abel. Denial of Service Attack — This attack is mainly to deny the legitimate users, network resources.
This type of attack can be performed using FataJack. All you need are the hardware and software resources and some patience. These attacks also depend on the activity of the users of the network to be cracked.
Backtrack is an operating system that is Linux-based and developed on top of Ubuntu. It comes with a number of security tools and can be used to gather information, trace the vulnerabilities and then exploit the network. If the users of the target network are very frequent and active on their network, then you will have considerably more chances to crack it. You have to have a basic knowledge of Linux-based operating systems and also a little bit of knowledge about Airrack and its different scripts.
You can restrict access to the network by allowing only the registered MAC addresses. You can head straight to the official YouTube channel to find full-fledged video series on using the tool on different platforms. Coming to the features, you can deep inspect hundreds of different network protocols.
We also get live capture along with offline analysis in various formats such as tcdump, Catapult DCT, and Pcap NG, amongst dozens of others. It is a Linux-only network tool, available for several distros, designed explicitly for Kali Linux and ParrotSec. There is no graphical user interface on this network hacking tool. You get a command-line interface and a list of commands to use. If it is not available, you can go with after-market wireless cards through USB.
You will need Aircrack-ng suite, ifconfig, and iwconfig for Wifite to work. There are several optional tools such as shark, reaver, amongst others, to augment the chances.
All the cracked passwords and handshakes are in the current directory. Next up, we have a man-in-the-middle attack on a WIFI network. Wifiphiser is a rogue access point network framework that can conduct red team engagements and WIFI penetration testing. Similar to Wifite, this program is also available exclusively for Linux. You will need a working wireless adaptor with Monitor and AP mode.
A plethora of community-driven phishing templates is available with the tool for deployment in different scenarios. Users can also write complicated Python driven scripts to create new phishing scenario templates for conducting target-oriented attacks.
There are several phishing templates of drivers and router firmware updates that are ready to use. You can take a leaf out of the booklet and modify them according to the requirements at hand. Wifiphisher offers an interactive textual interface, a much-needed relief from the mundane command-line offered by other tools. You are out in public, often seeing tons of WIFI networks but password protected.
It comes with monitor mode support. Officially takes an average of 4 to 10 hours through the online brute-force method. In reality, the time is significantly shorter and almost half of the official estimation to guess the WPS pin and get ahold of the passphrase.
On the other hand, using an offline attack may take seconds or a few minutes when the AP is vulnerable. As a Reaver veteran user, you can rest assured that all the features are available through the GUI. Wait up; it gets even better here. Rfa also supports external scripts, paving the way for additional capabilities. You need to install bcmon. The bcmon file can also be downloaded directly when opening the rfa. After a brief pitstop at Android station, we are back to Linux with airgeddon.
An actively developing WIFI hacking tool. Unlike other network hacking tools, here, we get full support for 2. This makes things a lot easier when dealing with multiple networks.
For rule-based and brute-force attacks, the tool relies on aircrack, hashcat, and crunch tools. You can also drag and drop files directly into the console window to make inputs and entering file paths easier. This comes with an auto-sizing console window that detects the resolution on its own and adjusts accordingly. The WIFI hacking tool also offers quick deployments and implementation through using the docker image.
You can either use the already built image on the Docker hub or create your own. Great Product Written by pfjj. Works smoothly with any rooters. Written by Pande.

It was discovered a security flaw on Hashcat to hack the WPA protocol. This vulnerability makes it possible to hack the PSK shared WiFi key thus making it possible to access a wireless network.
There is no need to catch a complete 4-Way Handshake , the hacking is focused on the RSN IE which means to be a piece of robust security network information. The hacker is in direct communication with the WiFi terminal. He no longer needs to capture the bits that a user will receive to connect to a network.
Which means that anyone can access a WiFi directly and at any time because he sees the password displayed in clear on his machine. Most routers are concerned because this flaw concerns Don't use this software on other WiFi than yours because it is totally illegal and liable to criminal prosecution.
The best experience can be made by respecting the laws of your country. A hacker will not crack WiFi codes for nothing. Now we are not talking about white hats but we are talking about black hats, those who hack into WiFi connections for bad intentions. Indeed, these hackers will interfere with the privacy of Internet users and they will retrieve all information and personal data.
For example credit cards, files going in and going out, emails Users connected on the network will not notice anything! But you have to know that this could also be done from a smartphone. You can check yourself from your computer in your network properties if a third party is logged in. That would mean that you are hacked.
This could be dangerous if you selected the way you share your printer or your files. Everyone can have access to it and dissimulate a virus in it. What you should do is to install a good antivirus, run an update and run a deep scan. Then you should install a firewall if it is not already given with the antivirus you previously installed. After that, you should rename your router and change the password. This step could be a little complicated, but generally the user manual indicates the steps to do this task.
The Alliance defined these in response to serious weaknesses that researchers had found in the previous system, WEP Wired Equivalent Privacy. Very often in the network options is written " private WiFi network ", that is password protected, but now WiFi password crack has become simple and an easily-solved problem. It is clearly impossible to protect a wireless network unless you change the key every minute.
