How To Crack The Wifi Password For Mac
If anyone is not connected the Wi-Fi, cracking is not possible as we need a wpa handshake. We can capture handshake by sending deauthentication packets to client connected to Wi-Fi. Aircrack cracks the password. Step-1:-First open terminal. If your Android phone is Rooted & looking for how to crack mobile hotspot password, you can use this “Wifi Password Viewer” app to reveal your wifi password. 3) Use WiFi password sharing apps for Smartphones. There are smartphone apps with a database of credentials of various Wi-Fi access points across the world.
. Start. Prev. 1. Introduction The world has changed since was written in 2008. While there are some wireless networks still using WEP, there has been a mass migration to WPA2-AES wireless security.
A key reason for this move is 802.11n, which requires WPA2/AES security enabled in order to access link rates over 54 Mbps. Cracking techniques have changed too. While most techniques still use some form of dictionary-based exploits, the power of the cloud has also been brought to bear on password cracking. In fact, prompted Tim to ask me to revisit the original article and update it to include the new methods Dan described. So here I am. Brandon's article provides a good WPA primer, so I won't repeat that here.
The key things that you need to know are:. The information we need to capture is contained in transmissions between AP and STA (client) known as the 'four-way handshake'. The techniques used to recover the passphrase are primarily forms of So, let's just jump in after a few 'need to knows'. Warning and Disclaimer. Accessing or attempting to access a network other than your own (or have permissions to use) is illegal. SmallNetBuilder, Pudai LLC, and I are not responsible in any way for damages resulting from the use or misuse of information in this article. Note: The techniques described in this article can be used on networks secured by WPA-PSK or WPA2-PSK.
References to 'WPA' may be read 'WPA/WPA2'. Setup To crack WPA-PSK, we'll use the venerable Live-CD SLAX distro. It's free to download, but please consider donating, since this really is the Swiss Army knife of network security. As you can see from my system specs in Table 1, it doesn't take much computing power to run WPA cracks.

BackTrack 5 R3 is the current version over at so that's what we'll be using. First, the BackTrack ISO. I decided to boot BackTrack as a USB thumb drive with 4 GB of persistence.
For this I used a 16 GB USB thumbdrive. Recon with Kismet Open up, the venerable wireless surveillance tool ( Backtrack Information Gathering Wireless Analysis WLAN Analysis Kismet).
Upon opening Kismet you will need to select your wireless interface, which you can grab by typing 'iwconfig' in a terminal. Kismet is a great surveillance tool, but that is only one of its many talents. It captures raw packets while operating, which we can use later to attack weak PSKs, having captured a client connection while listening.
It also has some interesting alerts built in, to warn you of potential evil-doers within wireless range. To top it off, Kismet is completely passive and therefore undetectable. In of our original WEP cracking series, Humphrey Cheung wrote a great introduction to recon with Kismet. Recon for WEP cracking and WPA cracking is very similar, so I won't repeat all that information here. Instead, I'll just point out a few settings and options that I find useful as well as explain a bit of the interface. I would add, however, that Kismet is very versatile and customizable with great context-sensitive help menus.
In the main network list, access points are color coded by encryption method, which we also see indicated in the 'C' column. Green (N) indicates no encryption method, while Red (W) indicates WEP encryption. Yellow (O) indicates other, usually meaning WPA / WPA2.

You can see that highlighted an SSID provides more details about that specific AP. Figure 1: Kismet Information Screen The other interesting parts of the Network List display for our purposes include the T, Ch and the Pkts columns. The Ch column, as one might expect, is the channel of the access point.
We'll need this information later if we employ an active attack. The Pkts column lists the number of packets captured by Kismet for a particular access point. While not completely relevant, it gives us a decent ball-park measurement of both network load and proximity. Higher network load usually translates to higher number of connected clients, which increases the chance that we could capture a client association passively.
Kismet defaults to autofit mode, where you can sort the networks and bring up the Network Details page by highlighting an AP and hitting enter. The Network Details page list all sorts of interesting information about the network most notably the WPA encryption scheme, BSSID and number of clients associated with the access point. Pressing c while in the Network Details view will bring up the connected Clients List. The Client List shows all the nodes with traffic associated with the access point.
This is one reason it's nearly useless to set MAC filters at a router. In seconds, Kismet can give an observer your client MACs, which can then be easily configured to the attacker's network adapter. The client list can also be shown on the main page by selecting 'Client Details' under View as shown in Figure 1 above.
Passive Attack In a passive attack, all we need to do is listen on a specific channel and wait for a client to authenticate. Kismet is the weapon of choice here, although airodump-ng works too. Kismet gives you much more control and information than airodump-ng, but unfortunately doesn't provide notification to alert you of a successful WPA-PSK association four-way handshake. Airodump-ng does, but gives you less dynamic control of the capture card's behavior and very little information (compared to Kismet). General Kismet recon and capture steps for a passive WPA-PSK attack are:.

Start Kismet. Sort the networks (Ex: by channel, press 's' then 'c'). Lock channel hopping onto the channel of interest (highlight the target AP and press 'L'). Wait until a client connects to capture the association.

As announced before we would be writing related to, This post is the second part of our series on wifi attacks and Security, In the first part we discussed about various terminologies related to wifi attacks and security and discussed couple of attacks. This post will also show you how one can easily crack in no time. Security Issues With WEP WEP (Wired Equivalent Privacy) was proved full of flaws back in 2001, WEP protocol itself has some weakness which allows the attackers to crack them in no time. The biggest flaw probably in a WEP key is that it supports only 40bit encryption which means that there are 16million possibilities only. For more information on WEP flaws, kindly read the WEP flaws section. Requirements:- Here is what you would require to crack a WEP key: 1.
Backtrack or any other Linux distro with aircrack-ng installed 2. A Wifi adapter capable of injecting packets, For this tutorial I will use Alfa AWUS036H which is a very popular card and it performs well with Backtrack You can find compatible wifi card lists. Procedure:- First Login to your Backtrack / Linux distro and plug in your Wifi adpter, Open a new konsole and type in the following commands ifconfig wlan0 up. Bssid shows the of the AP, CH shows the channel in which AP is broadcasted and Essid shows the name broadcasted by the AP, Cipher shows the. Now look out for a wep protected network In my case i’ll take “linksys “ as my target for rest of the tutorial Attacking The Target Now to crack the WEP key you’ll have to capture the targets data into a file, To do this we use airodump tool again, but with some additional switches to target a specific AP and channel. Most importantly, you should restrict monitoring to a single channel to speed up data collection, otherwise the wireless card has to alternate between all channels.You can restrict the capture by giving in the following commands airodump-ng mon0 –bssid -c (channel ) -w (file name to save ).
Wait till it reaches 20000 packets, best would be to wait till it reaches around 80,000 to 90,000 packets.Its simple more the packets less the time to crack.Once you’ve captured enough number of packets, close all the process’s by clicking the into mark which is there on the terminal Cracking WEP key using Aircrack Now its time crack the WEP key from the captured data, Enter the following commands in a new konsole to crack the WEP key aircrack-ng (name of the file ) In my case i enter aircrack-ng RHAWEP-0.1-cap With in a few minutes Aircrak will crack the WEP key as shown.
