Crack WEP password (wi-fi)

JOIN OUR FACEBOOK GROUP

To crack WEP, you'll need to launch Konsole, BackTrack's built-in command line. It's right there on the taskbar in the lower left corner, second button to the right. Now, the commands.

backtrack download page :click here

First run the following to get a list of your network interfaces:

airmon-ng

The only one I've got there is labeled ra0. Yours may be different; take note of the label and write it down. From here on in, substitute it in everywhere a command includes (interface).

Now, run the following four commands. See the output that I got for them in the screenshot below.


airmon-ng stop (interface)
ifconfig (interface) down
macchanger --mac 00:11:22:33:44:55 (interface)
airmon-ng start (interface)

If you don't get the same results from these commands as pictured here, most likely your network adapter won't work with this particular crack. If you do, you've successfully "faked" a new MAC address on your network interface, 00:11:22:33:44:55.

Now it's time to pick your network. Run:

airodump-ng (interface)

To see a list of wireless networks around you. When you see the one you want, hit Ctrl+C to stop the list. Highlight the row pertaining to the network of interest, and take note of two things: its BSSID and its channel (in the column labeled CH), as pictured below. Obviously the network you want to crack should have WEP encryption (in the ENC) column, not WPA or anything else.

Like I said, hit Ctrl+C to stop this listing. (I had to do this once or twice to find the network I was looking for.) Once you've got it, highlight the BSSID and copy it to your clipboard for reuse in the upcoming commands.

Now we're going to watch what's going on with that network you chose and capture that information to a file. Run:

airodump-ng -c (channel) -w (file name) --bssid (bssid) (interface)

Where (channel) is your network's channel, and (bssid) is the BSSID you just copied to clipboard. You can use the Shift+Insert key combination to paste it into the command. Enter anything descriptive for (file name). I chose "yoyo," which is the network's name I'm cracking.

You'll get output like what's in the window in the background pictured below. Leave that one be. Open a new Konsole window in the foreground, and enter this command:

aireplay-ng -1 0 -a (bssid) -h 00:11:22:33:44:55 -e (essid) (interface)

Here the ESSID is the access point's SSID name, which in my case is yoyo. What you want to get after this command is the reassuring "Association successful" message with that smiley face.

You're almost there. Now it's time for:

aireplay-ng -3 -b (bssid) -h 00:11:22:33:44:55 (interface)

Here we're creating router traffic to capture more throughput faster to speed up our crack. After a few minutes, that front window will start going crazy with read/write packets. (Also, I was unable to surf the web with the yoyo network on a separate computer while this was going on.) Here's the part where you might have to grab yourself a cup of coffee or take a walk. Basically you want to wait until enough data has been collected to run your crack. Watch the number in the "#Data" column—you want it to go above 10,000. (Pictured below it's only at 854.)

Depending on the power of your network (mine is inexplicably low at -32 in that screenshot, even though the yoyo AP was in the same room as my adapter), this process could take some time. Wait until that #Data goes over 10k, though—because the crack won't work if it doesn't. In fact, you may need more than 10k, though that seems to be a working threshold for many.

Once you've collected enough data, it's the moment of truth. Launch a third Konsole window and run the following to crack that data you've collected:

aircrack-ng -b (bssid) (file name-01.cap)

Here the filename should be whatever you entered above for (file name). You can browse to your Home directory to see it; it's the one with .cap as the extension.

If you didn't get enough data, aircrack will fail and tell you to try again with more. If it succeeds, it will look like this:

Full size

The WEP key appears next to "KEY FOUND." Drop the colons and enter it to log onto the network.

Problems Along the Way

With this article I set out to prove that cracking WEP is a relatively "easy" process for someone determined and willing to get the hardware and software going. I still think that's true, but unlike the guy in the video below, I had several difficulties along the way. In fact, you'll notice that the last screenshot up there doesn't look like the others—it's because it's not mine. Even though the AP which I was cracking was my own and in the same room as my Alfa, the power reading on the signal was always around -30, and so the data collection was very slow, and BackTrack would consistently crash before it was complete. After about half a dozen attempts (and trying BackTrack on both my Mac and PC, as a live CD and a virtual machine), I still haven't captured enough data for aircrack to decrypt the key.

So while this process is easy in theory, your mileage may vary depending on your hardware, proximity to the AP point, and the way the planets are aligned. Oh yeah, and if you're on deadline—Murphy's Law almost guarantees it won't work if you're on deadline.

troubleshoot windows 7 software/driver problems

While checking control panel
options, I found a very useful feature of Windows 7. Windows 7 is indeed most advanced and mysterious OS. It has self-diagnostic and self-repairing/optimization methods. Have anybody ever checked Windows event logs to see how much more is tracked? Personally, I disable all Windows logs to prevent unnecessary I/O load (although low impact only). Now moving to tutorial:

Open Control Panel and change view to small icons. Open 'Performance Information and Tools'. In left pane, click Advanced tools. In Advanced Tools, check if any issue is listed under Performance issues. If any issue is listed there, then click it and read the information in the dialog box that shows problematic programs/drivers. It also offer even log link to see tracking detail.
Now it is up to you to solve the problem
via uninstalling/upgrading program/driver

Many of us know that it is possible to copy or move files & folders in Windows by either using your mouse to right click, select Copy and then Paste, or your keyboard’s shortcut key CTRL+C to copy, CTRL+X to cut (for moving) and CTRL+V to paste. The biggest factor on the time taken to copy or move the files very much depend on the hard drive’s speed (5400RPM, 7200RPM, SSD) and also the interface (PATA, SATA, SCSI). However, it is still possible to shorten the duration in copying or moving files if you use third party software to do it instead of relying on the Windows built-in function

I simply copied a folder containing 2319 files, ranging from files as small as 1KB to as big as 700MB to another hard drive using the software’s default settings. The file copying testing methodology which I used is very simple and I have to admit that it is not enough to determine which is the “best” or “fastest” file copying software. However, the results does give you a hint on which file copy software you should be try and avoid.

FastCopy 2.08 (57 seconds)

ExtremeCopy Pro 1.5.1 (57 seconds) *

TeraCopy 2.12 (65 seconds) *

RichCopy 4.0.217 (66 seconds) *

KillCopy 2.85 (74 seconds)

Ultracopier 0.2.0.15 (75 seconds)

PerigeeCopy 1.2 (75 seconds) *

Robocopy (75 seconds)

Windows 7 (76 seconds)

Copy Handler 1.32.276 (77 seconds) *

MiniCopier 0.5 (79 seconds)

Copywhiz 4.0 Build 3 (82 seconds)

SuperCopier 2.2 (86 seconds) *

Roadkil’s Unstoppable Copier 5.2 (86 seconds)

QCopy 1.0.2 (409 seconds)

I am quite surprise to find that only about half of the file copy software is able to copy faster than the default Windows 7 copy function and the rest takes longer time to finish copying. Hopefully this simple test will be an eye opener to those that are using the slower file copy software.

The good thing about file copying software is the ability to that failed tresumeo copy. In Windows, if the copy failed, you’d have recopy and replace existing files that are already copied. Some file copy software above that are marked with an asterisk (*) are those that can completely replace Explorer copy and move functions, allowing you work with files as usual. For example, using the hotkey CTRL+C and CTRL+V will automatically make the file copy software to copy and paste instead of using the Windows built-in copy function.

Installing Windows 7 using a pendrive is very much faster than that from DVD/CD. You just need to follow some small steps to do this. You can keep this pendrive/USB drive for future installation of Windows 7. If you are a beginner or dont want to get messed up by typing in all commands, here is a Free Utility To Create A Bootable USB To Install Windows 7, Vista & Server 2008(http://cid-f52381d9f2fd5fd8.skydrive.live.com/browse.aspx/ABUSB). This tool will help you to automate the process of bootable pendrive’s and you can install windows 7 from pendrive easily. If not you can follow this guide to install windows 7 from a pendrive.

installing of utility

Check USB drive (To check whether your USB drive is connected or not)

Format USB Drive

Choose DVD or ISO image (To copy the needed files to USB drive)

Start the process to create bootable USB drive

Bootable USB automatically runs the required commands in Windows 7 / vista fro making the USB drive bootable. All you need to do is to follow these four simple steps.

Note: Windows XP users cant Run this utility. If you try to run it Bootable USB will show a message saying that ” Unsupported Opperating System. Supported Operating systems are Windows Vista (SP1 or later) “. On Vista with no SP there is an error diskpart which is solved later by microsft on SP1 and later.

And before selecting the DVD or ISO image of the Windows 7 or Vista installation make sure it is free of errors.

Bootable USB works with 64 bit versions of Windows 7, Vista too. Bootable USB is a nice and sleek application that is of great use in creating A Bootable USB To Install Windows 7.

Make sure you have a Pendrive or USB drive with a minimum of 4 GB space and you have the Windows 7 installation DVD. This tutorial is best suited if you have a Windows 7 DVD with you else you need to change it

...............................................

Format the Pendrive or USB drive in NTFS format first.

From the start menu right click on the command prompt and select “Run as administrator“.

Now type the following commands (Press enter key after each command).

diskpart. This is to open the disk partition program.

Now to show the list of drives type list disk.

You can see disk’s listed there. Note down the disk number of your pendrive eg. Disk .

Now type SELECT DISK X (where X is the number you noted down for the pendrive from step 5)

Now type CLEAN.

Now type the following commands by pressing enter after each one.

CREATE PARTITION PRIMARY

SELECT PARTITION 1 (Assuming your pendrive/ USB drive is 1).

ACTIVE

FORMAT FS=NTFS

ASSIGN

EXIT(Now the disk partition program will exit). Now we need to give some more commands.

Now insert the Windows 7 Installation DVD and to your DVD drive.

Here i am assuming DVD drive as G and Pendrive as I.(Change it accordingly).

Now type G:CD BOOT

Now type this command BOOTSECT.EXE/NT60 I: to update your USB drive with bootmgr code.

Finally copy all the contents from the Windows 7 DVD to your Pendrive. Make sure you don’t cause any errors.

Plug / Insert your pendrive to your PC and restart the system.

Now Enter the Bios system accordingly by pressing the key delete.(This may vary some times it will be F2 or F12. It depends on the type of your system. Any how during the start up your system will display which key to press to enter the Bios).

Now select the USB/ Pendrive as the first boot driver.(Set the first boot priority to USB drive.).

Now save the settings in Bios and restart and you will be able to Install Windows 7 using that pendrive.

BIOS Password Backdoors in Laptops

JOIN OUR FACEBOOK GROUP

in ebay there are lots of guys selling this tricks $45 and above.this is simple trick u can do it..i got it from dogbert article..hack heck team always gratitude for that

laptops bios locked with password, a checksum of that password is stored to a sector of the FlashROM - this is a chip on the mainboard of the device which also contains the BIOS and other settings, e.g. memory timings. For most brands, this checksum is displayed after entering an invalid password for the third time:

The dramatic 'System Disabled' message is just scare tactics: when you remove all power from the laptop and reboot it, there are not new penalties such as additional passwords, locks and so on. From such a checksum (also called "hash"), valid passwords can be found by means of brute-forcing. Another method commonly used is that instead of a checksum, a number is displayed from which a randomly generated password can be calculated. Quite often, vendors also resort to storing the password in plain text, and instead of printing out just a checksum, an encrypted version of the password is shown. Either way, my scripts can be used to derive valid passwords with the hash.

Some vendors have implemented obfuscation measures to hide the hash from the end user - for instance, some FSI laptops require you to enter three special passwords for the hash to show up (see other post). HP/Compaq laptops only show the hash if the F2 or F12 key has been pressed prior to entering an invalid password for the last time.

Depending on the "format" of the number code/hash (e.g. whether only numbers or both numbers and letters are used, whether it contains dashes, etc.), you need to choose the right script - it is mostly just a matter of trying all of them and finding the one that matches your laptop. It does not matter on what machine the script are executed, i.e. there is no reason to run them on the locked laptop.
This is an overview of the algorithms that I looked at so far:

Vendor	Hash Encoding	Example of Hash Code/Serial	Scripts
Compaq	5 decimal digits	12345	pwgen-5dec.py Windows binary
Dell	serial number	1234567-595B 1234567-D35B 1234567-2A7B	Windows binary&source
Fujitsu-Siemens	5 decimal digits	12345	pwgen-5dec.py Windows binary
Fujitsu-Siemens	8 hexadecimal digits	DEADBEEF	pwgen-fsi-hex.py Windows binary
Fujitsu-Siemens	5x4 hexadecimal digits	AAAA-BBBB-CCCC-DEAD-BEEF	pwgen-fsi-hex.py Windows binary
Fujitsu-Siemens	5x4 decimal digits	1234-4321-1234-4321-1234	pwgen-fsi-5x4dec.py Windows binary
Hewlett-Packard	5 decimal digits	12345	pwgen-5dec.py Windows binary
Hewlett-Packard/Compaq Netbooks	10 characters	CNU1234ABC	pwgen-hpmini.py Windows binary
Insyde H20 (generic)	8 decimal digits	03133610	pwgen-insyde.py Windows binary
Phoenix (generic)	5 decimal digits	12345	pwgen-5dec.py Windows binary
Samsung	12 hexadecimal digits	07088120410C0000	pwgen-samsung.py Windows binary

The .NET runtime libraries are required for running the Windows binary files (extension .exe). If the binary files (.exe) don't work out for you, install Python 2.6(not 3.0!) and run the .py script directly by double-clicking them. Make sure that you correctly read each letter (e.g. number '1' vs letter 'l').

Please comment on what make/model the scripts work and on what they don't. Also, be aware that some vendors use other schemes for master passwords - among them are e.g. IBM/Lenovo. Please understand that my motivation for reverse-engineering comes from a personal interest. If you find that your laptop does not display a hash or the scripts do not work for you for whatever reason, please use the vendor support. I will not accept offers to look at the specifics of certain models
