Cain and Abel : The top password recovery tool for Windows
UNIX users often smugly assert that the best free security tools support their platform first, and Windows ports are often an afterthought. They are usually right, but Cain & Abel is a glaring exception. This Windows-only password recovery tool handles an enormous variety of tasks. It can recover passwords by sniffing the network, cracking encrypted passwords using Dictionary, Brute-Force and Cryptanalysis attacks, recording VoIP conversations, decoding scrambled passwords, revealing password boxes, uncovering cached passwords and analyzing routing protocols.
#2
John the Ripper : A powerful, flexible, and fast multi-platform password hash cracker
John the Ripper is a fast password cracker, currently available for many flavors of Unix (11 are officially supported, not counting different architectures), DOS, Win32, BeOS, and OpenVMS. Its primary purpose is to detect weak Unix passwords. It supports several crypt(3) password hash types which are most commonly found on various Unix flavors, as well as Kerberos AFS and Windows NT/2000/XP LM hashes.
#3
THC Hydra : A Fast network authentication cracker which support many different services
When you need to brute force crack a remote authentication service, Hydra is often the tool of choice. It can perform rapid dictionary attacks against more then 30 protocols, including telnet, ftp, http, https, smb, several databases, and much more.
#4
Aircrack : The fastest available WEP/WPA cracking tool
Aircrack is a suite of tools for 802.11a/b/g WEP and WPA cracking. It can recover a 40 through 512-bit WEP key once enough encrypted packets have been gathered. It can also attack WPA 1 or 2 networks using advanced cryptographic methods or by brute force. The suite includes airodump (an 802.11 packet capture program), aireplay (an 802.11 packet injection program), aircrack (static WEP and WPA-PSK cracking), and airdecap (decrypts WEP/WPA capture files).
#5
L0phtcrack : Windows password auditing and recovery application
L0phtCrack, also known as LC5, attempts to crack Windows passwords from hashes which it can obtain (given proper access) from stand-alone Windows NT/2000 workstations, networked servers, primary domain controllers, or Active Directory. In some cases it can sniff the hashes off the wire. It also has numerous methods of generating password guesses (dictionary, brute force, etc). LC5 was discontinued by Symantec in 2006, but you can still find the LC5 installer floating around. The free trial only lasts 15 days, and Symantec won't sell you a key, so you'll either have to cease using it or find a key generator. Since it is no longer maintained, you are probably better off trying Cain and Abel, John the Ripper, or Ophcrack instead.
#6
Airsnort : 802.11 WEP Encryption Cracking Tool
AirSnort is a wireless LAN (WLAN) tool that recovers encryption keys. It was developed by the Shmoo Group and operates by passively monitoring transmissions, computing the encryption key when enough packets have been gathered. You may also be interested in the similar Aircrack.
#7
SolarWinds : A plethora of network discovery/monitoring/attack tools
SolarWinds has created and sells dozens of special-purpose tools targeted at systems administrators. Security-related tools include many network discovery scanners, an SNMP brute-force cracker, router password decryption, a TCP connection reset program, one of the fastest and easiest router config download/upload applications available and more.
#8
Pwdump : A window password recovery tool
Pwdump is able to extract NTLM and LanMan hashes from a Windows target, regardless of whether Syskey is enabled. It is also capable of displaying password histories if they are available. It outputs the data in L0phtcrack-compatible form, and can write to an output file.
#9
RainbowCrack : An Innovative Password Hash Cracker
The RainbowCrack tool is a hash cracker that makes use of a large-scale time-memory trade-off. A traditional brute force cracker tries all possible plaintexts one by one, which can be time consuming for complex passwords. RainbowCrack uses a time-memory trade-off to do all the cracking-time computation in advance and store the results in so-called "rainbow tables". It does take a long time to precompute the tables but RainbowCrack can be hundreds of times faster than a brute force cracker once the precomputation is finished.
#10
Brutus : A network brute-force authentication cracker
This Windows-only cracker bangs against network services of remote systems trying to guess passwords by using a dictionary and permutations thereof. It supports HTTP, POP3, FTP, SMB, TELNET, IMAP, NTP, and more.

How to rename all files in a directory?
Want to rename all files in a directory? well something similar can be achieved like this :
Select all the files in a folder (Ctrl+A), then right click on any file and select Rename.
And rename the file by pressing Alt+255. then press enter. All other files selected will be automatically renamed to (2), (3), ..... etc .. well u get an extra set of parenthesis in this case not exactly 1, 2, 3 etc.
But u'll see that the file which u selected for rename has no visible name. rename it to 1

Speed up Windows XP
Eliminate programs that run at start-up
Stopping programs from running at start-up is especially daunting because there is no single place you can go to halt them all. Some run because they're in the Startup folder, others because they're part of logon scripts, others because of Registry settings, and so on. But with a little bit of perseverance, you should be able to keep them from running.
* Start by cleaning out your Startup folder. Find it in C:\Documents and Settings\username\Start Menu\Programs\Startup, where username is your Windows logon name. Delete the shortcuts of any programs you don't want to run on start-up. As with any shortcuts, when you delete them, you're deleting only the shortcut, not the program itself. (You can also clear out the start-up items by going to Start > Programs > Startup, then right-clicking items you want to remove.)

* Next, clean out your Scheduled Tasks folder. Go to C:\Windows\Tasks, and delete the shortcuts of any programs that you don't want to run automatically on a schedule.
Note: You can bypass all the programs in your Startup folder on an as-needed basis. To stop XP from loading any programs in the Startup folder, hold down the Shift key during bootup. No programs in the Startup folder will run, but the items will still remain there so that they will start up as they would normally the next time you boot.
Using the system configuration utility
Taking the previous steps will stop the obvious programs from running at start-up, but it won't kill them all. The best tool for disabling hidden programs that run on start-up is the System Configuration Utility. To run it, type msconfig at a command prompt, and press Enter. (If that doesn't work, first do a search for msconfig.exe; when you find the file, double-click it.)
* To stop a program from running at start-up, go to the Startup tab in this utility, and uncheck the box next to the program. It can sometimes be difficult to understand what programs are listed on the Startup tab. Some, such as America Online, are clearly labeled. But often, you'll see a phrase or collection of letters, such as fs20. That's the name of the running file--such as fs20.exe, which is Free Surfer mk II, an excellent free pop-up killer.
* To get more information about a listing, expand the width of the Command column near the top of the Startup tab. Expand it enough and you'll see the start-up command that the program issues, including its location, such as C:\Program Files\Free Surfer\fs20.exe. The directory location should be another hint to help you know the name of the program.
* When stopping programs from running at start-up, it's best to stop them one at a time rather than in groups. You want to make sure that you're not causing any system problems by stopping them. So stop one, then restart your PC. If it runs fine, then stop another and restart. Continue doing this until you've cleared all the programs you don't want to run automatically.
Each time you uncheck a box and restart your PC, you'll get a warning that you've used the System Configuration Utility to disable a program from starting automatically. If you don't want to see that warning, disable it by checking the box in the dialog itself.
After you've used the system configuration utility to identify programs that run on start-up, you may want to try disabling them from with the programs themselves. So run each program that starts automatically, and see if you can find a setting that allows you to prevent it from running on start-up.
Speed up shutdown times
It's not only start-up that you'd like to speed up; you can also make sure that your system shuts down faster. If shutting down XP takes what seems to be an inordinate amount of time, here are a couple of steps you can take to speed up the shutdown process:
* Don't have XP clear your paging file at shutdown. For security reasons, you can have XP clear your paging file (pagefile.sys) of its contents whenever you shut down. Your paging file is used to store temporary files and data, but when your system shuts down, information stays in the file. Some people prefer to have the paging file cleared at shutdown because sensitive information such as unencrypted passwords sometimes ends up in the file. However, clearing the paging file can slow shutdown times significantly, so if extreme security isn't a high priority, you might not want to clear it. To shut down XP without clearing your paging file, run the Registry Editor (click Start > Run, then type regedit in the Run box) and go to:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Session Manager\Memory Management
* Change the value of ClearPageFileAtShutdown to 0. Close the Registry, and restart your computer. Whenever you turn off XP from now on, the paging file won't be cleared, and you should be able to shut down more quickly.
Note: Please be careful when editing the Registry; you can do a lot of damage here. Don't change or delete anything unless you know exactly what it is.
Disable services that run at start-up
Constantly running in the background of XP are services--processes that help the operating system run or that provide support to applications. Many of these services launch automatically at start-up. While you need many of them, some are not required, and they can slow down your system when they run in the background.
You can disable services at start-up by using the system configuration utility, similar to the way that you halt programs from running at start-up, except that you use the Services tab instead of the Startup tab. But the system configuration utility doesn't necessarily list every service that launches on start-up. A bigger problem is that disabling services is more of shot in the dark than disabling programs. When you disable a program, you can get a sense of what the program does. But when you disable a service through the system configuration utility, there's often no way to know what it does.
* A better way of disabling services at start-up is via the Services computer-management console. Run it by typing services.msc at the command prompt. The Services computer-management console includes a description of all services so that you can know ahead of time whether a particular service is one you want to turn off. It also lets you pause the service so that you can test your machine and see whether that service is needed.
* After you run the console, click the Extended tab. This view will show you a description of each service in the left pane when you highlight the service. The Startup Type column shows you which services launch on start-up--any with Automatic in that field. Click that column to sort together all the services that automatically launch on start-up. Then highlight each of those services and read the descriptions.
* When you find a service you want to disable, right-click it and choose Properties. In the Properties dialog box that appears, choose Manual from the Startup Type drop-down list. The service won't start automatically from now on, but you can start it manually via the console. If you want the service disabled so that it can't be run, choose Disabled. To test the results, turn off any services that you don't want to run by clicking Stop The Service in the left pane, or by right-clicking the service and choosing Stop.
Shut Down Windows XP in 7 Different Ways
There are so many different ways to turn off your Windows XP computer, let's look at some of them:
1. The standard approach - click the Start Button with your mouse, then select the Turn Off menu and finally click the Turn Off icon on the Turn Off computer dialog. [ooph!]
2. Press Ctrl+Esc key or the Win key and press u two times - the fastest approach.
3. Get the Shutdown utility from Download.com - it add the shut down shortcuts for you. Else create them yourself using approach 4.
4. Create a shutdown shortcut on your desktop. Right click on the desktop, choose New Shortcut and type shutdown -s -t 00 in the area where you are asked to specify the location of the program file. Now you can just double click this icon to turn off the computer. The best location would be your quick launch bar.
5. Press the Win key + R key to open the run window. Type shutdown -s -t 00. [s means shutdown while t means the duration after which you want to initiate the shutdown process].
If some open processes or application won't let you turn off, append a -f switch to force a shut down by closing all active processes.
Update: Added new shutdown tricks
6. Win+M to minimize all windows and then Alt+F4 to bring the Turn Off computer dialog.
7. Open Windows Task manager (by right clicking the Windows Task bar or Alt+Ctrl+Del) and choose Shut down from the menu. Useful when the Windows are not responding.

Top 15 Tips-n-Tricks for Mozilla Firefox
Following are 15 selected tips for Mozilla Firefox which are very useful. These tips have been collected from Mozilla website:
1. Use Windows Classic (9x/Me/2000) styled menus
If you want the menus to appear native to the Windows Classic appearance, add the following code to your userChrome.css file:
/* Windows Classic (9x/Me/2000) style Menus */
menupopup, popup {
border: 2px solid !important;
-moz-border-top-colors: ThreeDLightShadow ThreeDHighlight;
-moz-border-right-colors: ThreeDDarkShadow ThreeDShadow;
-moz-border-bottom-colors: ThreeDDarkShadow ThreeDShadow;
-moz-border-left-colors: ThreeDLightShadow ThreeDHighlight;
padding: 1px !important;
}
menubar > menu[disabled="true"] {
border: 1px solid transparent !important;
}
menubar > menu[_moz-menuactive="true"] {
border-top: 1px solid ThreeDHighlight !important;
border-right: 1px solid ThreeDShadow !important;
border-bottom: 1px solid ThreeDShadow !important;
border-left: 1px solid ThreeDHighlight !important;
background-color: transparent !important;
color: MenuText !important;
}
menubar > menu[_moz-menuactive="true"][open="true"] {
border-top: 1px solid ThreeDShadow !important;
border-right: 1px solid ThreeDHighlight !important;
border-bottom: 1px solid ThreeDHighlight !important;
border-left: 1px solid ThreeDShadow !important;
}
2. Use your own background image for the toolbars
In addition to changing themes, you can personalize Firefox even more by using your own toolbar background image. Add the following code to your userChrome.css file:
/* Use a background image for the toolbars:
(Substitute your image file for background.gif) */
menubar, toolbox, toolbar, .tabbrowser-tabs {
background-image: url("background.gif") !important;
background-color: none !important;
}
It's easiest to place the image file in the same location as the userChrome.css file. The image can be of any image format supported by Firefox.
3. Don't use bold text on the active tab
If you don't want the title of the active tab to be bold, add the following code to your userChrome.css file:
/* Make the active tab not bold */
tab[selected="true"] {
font-weight: normal !important;
}
4. Customize the display and location of the close tab button in the tab bar
You can customize the display and location of the close tab button in the tab bar by using about:config to edit the preference browser.tabs.closeButtons. Values:
0 - Display a close button on the active tab only
1 - (Default) Display close buttons on all tabs
2 - Don't display any close buttons
3 - Display a single close button at the end of the tab bar (Firefox 1.x behavior)
5. Remove items from the main menu
Some people like to place all their toolbar items on the same row as the menu. In order to save horizontal space, you can remove top menu items that you don't use. Add the following code to your userChrome.css file:
/* Remove the Go and Help menus
Id's for all toplevel menus:
file-menu, edit-menu, view-menu, go-menu, bookmarks-menu, tools-menu, helpMenu */
#go-menu, #helpMenu {
display: none !important;
}
6. Display Sidebar on the right
To display the Sidebar on the right side of the window instead of the left, add the following code to your userChrome.css file:
/* Place the sidebar on the right edge of the window */
hbox#browser { direction: rtl; }
hbox#browser > vbox { direction: ltr; }
7. Change the width of the Search Bar
By default, the Search bar on the toolbar is relatively small. To specify your own width in pixels, add the following code to your userChrome.css file:
/* Make the Search box flex wider
(in this case 400 pixels wide) */
#search-container, #searchbar {
max-width: 400px !important;
width: 400px !important;
}
8. Change the cursor for links that open in new window
This neat trick will change the mouse pointer when you hover it over links that will open a new window. Add the following code to your userContent.css file:
/* Change cursor for links that open in new window */
:link[target="_blank"], :visited[target="_blank"],
:link[target="_new"], :visited[target="_new"] {
cursor: crosshair;
}
9. Change the cursor for JavaScript links
This tip will change the mouse pointer when you hover it over links that will perform a JavaScript command. Add the following code to your userContent.css file:
/* Change cursor for JavaScript links */
a[href^="javascript:"] {
cursor: move;
}
10. Run Firefox from removable media
This advanced tip makes it possible to run Firefox from removable media, such as a USB memory stick. This will allow you to run Firefox with your personal settings from any computer, even those that don't have Firefox installed. It has only been tested on Windows XP/2000. The basic instructions are as follows:
A. Copy the Firefox application folder and your profile folder to the removable medium. In this example we will use R:\Firefox for the application folder and R:\FFProfile as the profile folder, assuming the drive letter for the removable media is R:.
B. Create a simple batch file called R:\Firefox.bat with the following line:
start \Firefox\firefox.exe -profile \FFProfile
C. Optionally, disable the disk cache to reduce the amounts of file writes to the removable storage by using about:config to set browser.cache.disk.enable to false.
The reason why a batch file is needed instead of a simple shortcut is that a shortcut uses absolute paths, and since the actual drive letter for the removable media may change depending on which computer it is plugged into, the relative path used in the batch file is guaranteed to work anywhere.
11. Speed up page rendering
By default, Firefox doesn't try to render a web page for 250 milliseconds while it's waiting for data. If you use about:config to add the Integer preference nglayout.initialpaint.delay, and set the value to 0, Firefox immediately starts to display the page, even without complete data. The drawback, especially on slower machines, is that the total time to display the page will be longer.
12. Enable Pipelining
Pipelining is an experimental feature, designed to improve page-load performance, that is unfortunately not well supported by some web servers and proxies. To try it out, by using about:config to set the following preferences:
network.http.pipelining
(Set this to true, to enable pipelining.)
network.http.proxy.pipelining
(Set this to true, to enable pipelining to the proxy server.)
network.http.pipelining.maxrequests
(Set this to 8, to have a maximum of 8 pipelining requests at once. Possible values are from 1 to 8.)
13. Specify where to store the cache
To specify in which folder the cache is stored, use about:config to add the String preference browser.cache.disk.parent_directory, and set the value to C:\Path To Cache. Replace Path To Cache with the actual path to your cache folder.
14. Specify the memory cache usage
Normally, Firefox determines the memory cache usage dynamically based on the amount of available memory. To specify a specific amount of memory cache, use about:config to add the Intefer preference browser.cache.memory.capacity, and set the value:
-1 - (default) Determine the amount of memory cache dynamically.
0 - None.
n - Memory capacity in kilobytes. For example: 4096.
To disable the memory cache completely, use about:config to set the preference browser.cache.memory.enable to false.
15. View page source using an external program
If you want to view the HTML source of a web page using an external text editor instead of the built-in source viewer in Firefox, use about:config to set view_source.editor.external to true, and then set view_source.editor.path to e.g. C:\Windows\Notepad.exe or whatever is your preferred text editor.
NOTE: Both files "userChrome.css" and "userContent.css" are found in Firefox Profile folder. To know more about please visit following link:
Speed Up Hard Disk speed
I only recommend doing this if you have 256mb of RAM or higher.
STEP 1: Start > Run > then type SYSEDIT.EXE
STEP 2: Expand the system.ini file window.
STEP 3: Scroll down almost to the end of the file till you find a line called [386enh]
STEP 4: Press Enter to make one blank line, and in that line type
Irq14=4096
NOTE: The above info for the new line is case sensitive
STEP 6: Select File > Save
STEP 7: Close SYSEDIT and reboot your computer
NOTE: Once your computer has been rebooted, you should notice a change in your hdd's performance. I have tested this on IDE hdd's and it has worked fine. I've read in a few locations online that it could possibly work for SCSI disks but I don't have any to attempt the theory. If someone does test it and can vouch for the SCSI's improved performance, please let me know.

How to Get DOUBLE Speed in Broadband internet
· Hw 2Get DOUBLE Speed in Brod band net # #
Tuning up MTU (Maximum Transmission Unit) to speed up Internet access
Now let me tell you one important fact related with tuning. Value of MTU depends upon how fast a connection you have, what kind of activities you perform (ask yourself a question. Are your a mild, average or high end user of Internet ? To put it in other words, Do you download little or nothing, or are an average surfer or are Internet savvy individual and download everything from programs,apps,patches to watching Internet audio/video real-time content?) Depending upon who you are as a user and what kind of connection (modem,dsl,cable or in rare cases T1/T3), this tuning may have little to significant effect on your Internet experience. All right MTU stand for Maximum Transmission Unit.
Value of MTU decides the size of Internet data packet. Bigger the size, more you can transfer.
Analogy could be made with a bucket. If bucket is small, you can carry little but it would be no strain on your strength. Bigger the bucket, more you can carry but it strains your physical strength. (Well! Its not that simple but good enough to understand). Objective should be find a perfect balance which works for you. I think maximum that you can put is as value of MTU is 1500 (but could be higher for your specific network) and it may not make sense making it smaller than 68.
Again this is a registry tweak unless and until you have a tweaking utility that can do it for you.
Open Registry by going to START-RUN and entering REGEDIT and Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\Tcpip\Parameters\Interfaces\ ID for Adapter. For this right click on right pane and add a key by the name MTU. For this key you can add a DWORD value from 68 to 1500 (or higher value is certain cases).
If you put less than 68, it will default to 68. If you put a value higher than 1500 or your Network permitted max, it will default to permitted max.
i
Enable automatic path MTU size detection and impro
As stated on previous tip (Tip 52), MTP size plays an important role in deciding Internet speed. But its not so easy to determine the right value of MTU. For those of us who fall in this category and would prefer computer to find that for us, follow trick may work. I can not say with confidence whether this would work across all network but it should and there is no harm in trying it out. Now before I do that let me tell you what this action will do.
Applying this trick, you would ask computer to automatically find out the maximum MTU size possible in the connection path to a host. This value could be different for different sites. I think this trick should pick the lowest common denominator across a particular path. Typically If MTU size is not optimized, this job has to be done by a router which would mean a significant waste of time (small chunks adds to a considerable loss if you imagine that there are billions of packets involved across the whole Internet) resulting in poor throughout and congestion on cyber lanes. All right this key is called EnablePMTUDiscovery.
Again this is a registry.Open Registry by going to START-RUN and entering REGEDIT and Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\Tcpip\Parameters\Interfaces\ ID for Adapter. For this right click on right pane and add a key by the name EnablePMTUDiscovery. For this key you can add a DWORD boolean value of 0 or 1 with 1 being TRUE (value that enables auto detection).
Since we are trying this tweak, set to 1 and enable the TCP to attempt to discover the MTU size over the specific path to host. Microsoft has an interesting article on many similar tips <TCP/IP and NetBT configuration parameters for Windows 2000 or Windows NT> and is titled TCP/IP and NBT Configuration Parameters for Windows (Q120642). <TCP/IP and NetBT configuration parameters for Windows 2000 or Windows NT>

· How to Access Blocked Websites?
·
· Blocking access to undesirable Web sites through the use of Internet protocol filters has been a common government tactic since commercial Internet access first became available here in 1995. China and Saudi Arabia are believed to extend greater censorship over the net than any other country in the world under the pretext of information control.
Most of the blacklisted sites in Saudi Arabia are either ***ually explicit or about religion, women, health, drugs and pop culture. They even block access to websites about bathing suits. So if you want to buy something to swim in, they seem to treat that as if it were ****ographic in Saudi Arabia.
In China, webites containing ***ually explicit content were among those blocked, but they also included sites on sensitive topics such as Tibet, Taiwan, and dissident activity. China also blocks access to Google News, Typepad and Blogger hosted blogs.
But what if an innocent website is accidentally blocked by your ISP or your government. There are always legitimate reasons to visit these blocked websites. We have listed a few methods to help you access blocked websites in school, college, office or at home.
Approach 1: There are websites Anonymizer who fetch the blocked site/ page from their servers and display it to you. As far as the service provider is concerned you are viewing a page from Anonymizer and not the blocked site.
Approach 2: To access the blocked Web site. type the IP number instead of the URL in the address bar. But if the ISP software maps the IP address to the web server (reverse DNS lookup), the website will remain blocked.
Approach 3: Use a URL redirection service like tinyurl.com or snipurl.com. These domain forward services sometimes work as the address in the the url box remain the redirect url and do not change to the banned site.
Approach 4: Use Google Mobile Search. Google display the normal HTML pages as if you are viewing them on a mobile phone. During the translation, Google removes the javascript content and CSS scripts and breaks a longer page into several smaller pages. [link] View this website in Google Mobile
Approach 5: Enter the URL in Google or Yahoo search and then visit the cached copy of the page. To retrieve the page more quickly from Google's cache, click "Cached Text Only" while the browser is loading the page from cache.
Approach 6: A recent Oreilly story on accessing blocked websites suggested an approach to access restricted web sites using Google language tools service as a proxy server. Basically, you have Google translate your page from English to English (or whatever language you like). Assuming that Google isn’t blacklisted in your country or school, you should be able to access any site with this method. Visit this site via Google Proxy
Approach 7: Anonymous Surfing Surf the internet via a proxy server. A proxy server (or proxies) is a normal computer that hides the identity of computers on its network from the Internet. Which means that only the address of the proxy server is visible to the world and not of those computers that are using it to browse the Internet. Just visit the proxy server website with your Web browser and enter a URL (website address) in the form provided.
