One-minute bt3 USB flash drive
Convenient, fast, and simple
Invalid, no refund

Optical Disk version bt3, about 694 MB, directly dial, and then use the disc boot, you can enter bt3, the connection is:
Http://ftp.heanet.ie/mirrors/backtrack/bt3-final.iso

USB flash drive bt3, about 783 MB, connection:
Http://cesium.di.uminho.pt/pub/backtrack/bt3final_usb.iso


Preparation: A 1g or more USB flash drive, SD card, or TF card. Of course, TF or SD card requires a card reader.
Read it from the computer,
We recommend that you format the USB flash disk to FAT32, which saves space than the fat format.
Please go to Baidu on your own. I will not talk about it here

After formatting, the USB flash disk is empty.

Insert to USB port of Computer


1. Download the USB flash drive bt3 File
Address: http://cesium.di.uminho.pt/pub/backtrack/bt3final_usb.iso
The file size is about 783 MB.

2. Load the ISO file to the virtual optical drive. In the virtual optical drive, obtain the following file:


Of course, you can use WinRAR to decompress the package to a folder. It is expected that there will be no problem. I don't want to decompress the package because of space problems.
I directly planted it to a virtual optical drive, saving space and no need to decompress it.

3. copy the files (bt3 and boot) in the virtual optical drive to the USB flash drive.



4. Click Start-run, Enter cmd, and press enter to enter the command line mode.



Enter the drive letter of the USB flash drive. Mine is I:, and press Enter.

Enter CD boot and press Enter.

Enter bootinst. BAT and press enter to start making bt3.



This kind of screen will appear at the beginning of production, which means that this operation will overwrite the USB flash drive.
MBR (that is, the boot area), assuming this partition is a partition on your hard disk, then your Windows System
Will not start, please be careful, Press X to stop the operation, press other random keys to continue making
I am operating on a USB flash drive, so don't worry, just press the random key.




The figure above shows the prompt after creation. The Boot Record is set successfully and you can press the random key to exit the production process.
The production process is very fast, less than 10 seconds. Others, he just wrote the boot area of the USB flash disk again.
OK.

So far, this USB flash drive can guide the system into bt3.

Of course, how to set your computer to USB flash drive boot is your problem. I started USB HDD.

-------------------------------------------------- I am a downstream cutting line ------------------------------------------------------

Cracking: The system is guided to the bt3 selection screen. You can select bt3 with KDE at the end. Why do you choose this?
I don't know what KDE is. I don't want to know either. If you are interested, please go to Baidu


1. After Entering the bt3 desktop, you need to use the command line mode. In fact, it is not difficult. Note that we need to start
The command line status of bt3. Click the following icon to start the command line status of bt3.


That is, the icon that draws the blue circle. We need to click this icon for all operations.

2. Click the icon to enter the command line status and enter the command: ifconfig-
This command is used to list the network cards in your computer. If not, it means that the network cards are not listed.
If it is listed, it indicates that it is supported and cannot capture packets.



That is, enter the command and press enter to see the information. Pay attention to the Blue Circle in the figure.
The MAC code of your Nic is displayed, and my Mac code ends with 16-E6.
This indicates that my network adapter is supported. My wireless network adapter is Intel 2915abg, and bt3 supports 2915abg packet capture.

The ENI is the ID of eth0, eth1, eth2 ......
The USB Nic is the ID of rausb0, rausb1, rausb2....

In the following example, we need to capture packets with eth1 and my internal network adapter.

2. Open another command form and do not know how to open it. Please go to the upper part of the article.
After opening, enter the command: airodump-ng-W 123 eth1
Then press Enter.

Note: The ID of your wireless network adapter may be rausb0, or eth0, eth1
Command Format: airodump-ng-W 123 <Nic ID>
You can



Enter the command and press enter to view the following information:




Several explanations
Bssid: the MAC address of the scanned wireless route. This address must be used for cracking.
PWR: signal strength of a wireless route
Beacons: number of packets sent to this route
# Data: number of packets captured by the NIC
Ch: the channel of the wireless route
ENC and cipher, which are the encryption methods of wireless routes
Essid: The SSID name of the wireless route

In this example, the content to be cracked must be ENC: WEP, cipher: WEP, such as yeroc, which is a suitable cracking object.
As for WPA encryption, you can try it on your own because you cannot catch enough data packets and you don't know if it can be cracked.

Now we need to check that the value of the # data column of the wireless route changes faster than that of the slave, and there are more data packets than the slave, so that we can crack it.
We can see that yeroc already has 17 data packets, so we can crack it.

3. Start cracking, and then open a command line mode. What? I don't know how to enable the command line mode. Smoke S and read the upper part of the article.
Open the command line form and run spoonwep.
Then press Enter.






After spoonwep is enabled

Victim Mac: in this column, enter the MAC code of the wireless route we want to crack, that is, the MAC address.
Note: It is the MAC code of the wireless route to be cracked, not the MAC code of your wireless Nic

In net card, select the wireless network adapter used in the airodump-ng-W 123 eth1 command.
For eth1, I chose eth1.
Channel: select the channel of the wireless route to be cracked. If yeroc is set to 6, I select 6.
INJ rate, which is the default value.
In the launch column, select "0841 replay attack" from the drop-down list.
Click launchbutton to start cracking.



After the attack starts, we need to capture 60 thousand to 100,000 packets to crack the attack.
I caught the packet for 40 minutes and then cracked it.
At this time, you cannot see the packet changes because the execution is in progress.
No.

Open a command line form, enter airodump-ng-W 123 eth1, and press Enter.
You will see that # The data packet is constantly changing. Because when spoonwep is executed, the airodump-ng form will display the data
Therefore, after starting the attack, run airodump-ng-W 123 eth1 again to observe the speed at which the number of data packets changes.
It may take about a long time to crack the attack.
If it is very slow, it can be started before going to bed for computation and cracking
Assuming that the attack is very fast, it will be able to be cracked during a bath.

This requires you to observe the speed at which the data packet changes during the cracking, and then arrange a time to crack it.
