Recently I can to know about this report from a blog, “If a computer user double his typing speed, he is saving 300 hours in one year!” Amazing! Isn’t it?

#1 Position : Choose a comfortable chair and sit straight. Place your fingers correctly on the keyboard. Type using the pads of your fingers, don’t use finger tips or nails. The Keyboard should be at waist level approximately.

#2 Placement : Use both your hands for typing. You can check this visual tutorial for understanding placement of your fingers on the appropriate keys easily. Use the thumb for Space Bar. It is better to memorize the location of the keys.

#3 Avoid Seeing : Yes, you should not see the keyboard while you type. You should have military level of discipline. Look at the screen or the source paper. After you are familiar with the finger placements you can try this. While riding bicycle, what will you see? The road or the pedals?

#4 Use Emoticons : Emoticons are nothing but textual expressions representing the face of a writer’s mood or facial expression. You can find them in many portals including social networks, forums, IM, blog comments and so on. Emoticons usually have symbols. By using them often you can be familiar with symbols location in keyboard and you can type it without seeing soon.

#5 Type Along : Try to type what you hear, like news reports, songs, two people talking around, so on. It will help you to become more familiar with various words.

#6 Avoid Typos : While practicing don’t spend time on fixing your typos. Instead carry on typing. Because you are just training your hands and concentrating on typing faster.

#7 Get Addicted : I improved my typing speed by using TypeRacer. It is a multiplayer typing game where you race others by typing quotes from popular books, movies, and songs. You can also find TypeRacer applications in Orkut and Facebook.

#8 Softwares : You can purchase a typing lesson software or try the free ones available online. But make sure that program is capable of measuring your typing speed. You can also try free Flash typing games.

#9 Practice : Last but not least, nothing can be done without practicing. Practice as much as possible. Do it regularly with extreme patience. But don’t practice if your fingers become tired. Leave some gap.

How to avoid being a victim of Social Engineering Attacks ?

• Never provide your personal information or information about your company/organization unless you are certain of the person’s identity and authority to have that information.

• Never reveal personal and financial information in email and do not respond to email solicitations for this information. This includes the links sent in email.

• If you are not sure whether an email you got is legitimate or not, then try to verify it by contacting the company/organization directly indeed. Do not use the contact information provided in that email instead use the one from your previous emails.

• Always check the URL of a web site. Phishing web sites may look identical and genuine to a legitimate site, but the URL may slightly differ like misplaced words and letter. Also check the domain name extensions (Like .com or .org).

• Never send sensitive and worthy information over the Internet before checking the security of a website.

• Always be aware of unsolicited phone calls, visits and emails from individuals asking about your employees or other such information. Better try to verify his or her identity directly with the company.

If you are victim of this…..

• If you revealed sensitive information about yourself and your organization, report it to the concerned people within the organization.

• If  your financial accounts may be compromised then contact your financial institution immediately and close the accounts that may have been compromised.

• Consider reporting the attack to the police, and file a report with the Federal Trade Commission.

Don’t give any sensitive information to anyone unless you are sure about the person’s identity and that they should have access to the information. Choose not to be a victim.

To do this tutorial you don’t need to have any extra skills or creativity or whatever they say. All you need is little patience and most importantly, don’t do any Photoshop tutorial in a hurry. They won’t give good output/result.

Try to think creatively and you will get more than the desired output. Always remember no one can teach you creativity.

Correct Registry Value for USB Mass Storage device

1. Go to Start > Run , type “regedit” and press enter, this will open registry editor.

2. Navigate to the key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\USBSTOR

Now remove and connect the pen drive again, it should work fine, if it does not, then it means the drivers are missing. Follow the steps below to solve the issue.

Install USB Mass Storage Device drivers

In case the USB Mass Storage drivers are not installed, windows will prompt you to install the driver. In such a case, windows will launch Hardware Update Wizard. If you have USB Mass storage drivers, you can install it and restart the computer, it should work. If not, you can download the USB Mass Storage drivers here. Download and uznip the driver files on your desktop.

i) In hardware update wizard, Select the option to install the driver from a specific location and click next.

ii) Now on this screen, click browse and select the path on which you have un-zipped the drivers and press ok.

NOTE: Windows may give you a warning that the drivers has not passed Windows logo testing, so stop installation or Continue anyway, Select Continue anyway to complete installation.

Now restart your computer and re-insert your pen drive, it should now work.

Sometimes the websites thrown up by Google Search results cannot be viewed unless you are a member in that website. Of course, you have to register to become a member, which is quite annoying and frustrating for some users. You can beat this problem by visiting the Google Cache copy of that website. Click the Cached link to do this trick. If this trick fails, you can use Be The Bot site which will fool the site by making it think that Google Crawling Bot is accessing it.

I have just tested the latest Trinity Rescue Kit 3.3 build 334 and confirm this freeware stills able to recover or reset Windows 7 administrator account password. It works just nice as expected on my Dell Latitude with vanilla Windows 7 Ultimate installation.

In case you forget the Windows admin account password and find no other way to recover it (i.e. no password reset disk, no clue from the password hint, etc), the TRK freeware might able to take you out of this nightmare: 1) Download TRK ISO file and verify its MD5 checksum against the published file checksum value before burning the CD image to CD/DVD-ROM.

For Netbook without optical drive, you have to boot the TRK CD/DVD-ROM from another computer with CD/DVD-ROM drive and refer to the guide of create a bootable TRK USB flash drive.

2) Update the computer boot drive priority in BIOS setup to make sure it boots up from USB flash drive or CD/DVD-ROM drive, whichever applicable.

Some BIOS might have a hotkey which if pressed during start-up could allow user to choose a different boot drive as needed. For example, Dell Latitude uses F12, latest AMI BIOS uses F8, etc.

3) Boots the computer up from Trinity Rescue Kit media. At the (Linux) command prompt, type the following command and press ENTER:

winpass -u Administrator

CAUTION

• TRK is actually a customized Linux distribution. Thus the command is case-sensitive, i.e. “a” is not equal to “A”
• The Windows 7 real, built-in administrator account is not enabled by default and thus you have to enable this built-in administrator account with TRK first. Otherwise, replace Administrator account name with the user-defined administrator account. If this is called Walker, make sure you replace “Administrator” with “Walker” and not “walker”.

4) At the “user edit menu” prompt, type 1 and press ENTER key to effectively reset the said Windows account password to blank (empty) password! Having said that, you will able to log in with this account again to Windows 7, even if you have forgotten the password.

One of the most famous tools of TRK is probably the winpass shell script that simplifies the execution of chntpw utility to reset or recover the Windows account password. Best of all, TRK is a tiny Linux distribution (less fat) and it is good to boot up from a 128MB USB flash drive. If you still keep one of such smaller thumbdrive, now is just nice to make use of it. Steps to create bootable USB drive for Trinity Rescue Kit 1) Download the latest release of TRK from trinityhome.org and verify MD5 checksum of the downloaded ISO file against the one published in download page. 2) Burn the ISO file to CD/DVD-ROM, with any optical disc authoring software, such as Nero, PowerISO, UltraISO, or the built-in Windows Disk Image Burner feature in Windows 7. 3) Boots up from the TRK CD/DVD-ROM to the TRK (Linux) command prompt. Plug in the USB flash drive and execute dmesg command for the attached USB flash drive device file. As shown in this screenshot, my Apacer 128MB USB flash drive is attached as /dev/sdb in Linux: 4) Now, execute trk2usb command to create the TRK bootable USB flash drive (where -d specify the USB mass storage device file; -s to specify size in MB):

trk2usb -d /dev/sdb -s 128

Read the WARNING message carefully and understand the consequence before entering “ok” to proceed. I have NOT tried a gigabyte thumbdrive with multiple logical drives setup by partition table (wonder will trk2usb destroy the original partitions, even if explicitly specify the logical drive in -d option together with -n).

Thanks to the media, the word “hacker” has gotten a bad reputation. The word summons up thoughts of malicious computer users finding new ways to harass people, defraud corporations, steal information and maybe even destroy the economy or start a war by infiltrating military computer systems. While there’s no denying that there are hackers out there with bad intentions, they make up only a small percentage of the hacker community.

The term computer hacker first showed up in the mid-1960s. A hacker was a programmer — someone who hacked out computer code. Hackers were visionaries who could see new ways to use computers, creating programs that no one else could conceive. They were the pioneers of the computer industry, building everything from small applications to operating systems. In this sense, people like Bill Gates, Steve Jobs and Steve Wozniak were all hackers — they saw the potential of what computers could do and created ways to achieve that potential.

A unifying trait among these hackers was a strong sense of curiosity, sometimes bordering on obsession. These hackers prided themselves on not only their ability to create new programs, but also to learn how other programs and systems worked. When a program had a bug — a section of bad code that prevented the program from working properly — hackers would often create and distribute small sections of code called patches to fix the problem. Some managed to land a job that leveraged their skills, getting paid for what they’d happily do for free.

As computers evolved, computer engineers began to network individual machines together into a system. Soon, the term hacker had a new meaning — a person using computers to explore a network to which he or she didn’t belong. Usually hackers didn’t have any malicious intent. They just wanted to know how computer networks worked and saw any barrier between them and that knowledge as a challenge.

In fact, that’s still the case today. While there are plenty of stories about malicious hackers sabotaging computer systems, infiltrating networks and spreading computer viruses, most hackers are just curious — they want to know all the intricacies of the computer world. Some use their knowledge to help corporations and governments construct better security measures. Others might use their skills for more unethical endeavors.

In this article, we’ll explore common techniques hackers use to infiltrate systems. We’ll examine hacker culture and the various kinds of hackers as well as learn about famous hackers, some of whom have run afoul of the law.

The Hacker Toolbox

The main resource hackers rely upon, apart from their own ingenuity, is computer code. While there is a large community of hackers on the Internet, only a relatively small number of hackers actually program code. Many hackers seek out and download code written by other people. There are thousands of different programs hackers use to explore computers and networks. These programs give hackers a lot of power over innocent users and organizations — once a skilled hacker knows how a system works, he can design programs that exploit it.

Malicious hackers use programs to:
Log keystrokes: Some programs allow hackers to review every keystroke a computer user makes. Once installed on a victim’s computer, the programs record each keystroke, giving the hacker everything he needs to infiltrate a system or even steal someone’s identity.
Hack passwords: There are many ways to hack someone’s password, from educated guesses to simple algorithms that generate combinations of letters, numbers and symbols. The trial and error method of hacking passwords is called a brute force attack, meaning the hacker tries to generate every possible combination to gain access. Another way to hack passwords is to use a dictionary attack, a program that inserts common words into password fields.
Infect a computer or system with a virus: Computer viruses are programs designed to duplicate themselves and cause problems ranging from crashing a computer to wiping out everything on a system’s hard drive. A hacker might install a virus by infiltrating a system, but it’s much more common for hackers to create simple viruses and send them out to potential victims via email, instant messages, Web sites with downloadable content or peer-to-peer networks.
Gain backdoor access: Similar to hacking passwords, some hackers create programs that search for unprotected pathways into network systems and computers. In the early days of the Internet, many computer systems had limited security, making it possible for a hacker to find a pathway into the system without a username or password. Another way a hacker might gain backdoor access is to infect a computer or system with a Trojan horse.
Create zombie computers: A zombie computer, or bot, is a computer that a hacker can use to send spam or commit Distributed Denial of Service (DDoS) attacks. After a victim executes seemingly innocent code, a connection opens between his computer and the hacker’s system. The hacker can secretly control the victim’s computer, using it to commit crimes or spread spam.
Spy on e-mail: Hackers have created code that lets them intercept and read e-mail messages — the Internet’s equivalent to wiretapping. Today, most e-mail programs use encryption formulas so complex that even if a hacker intercepts the message, he won’t be able to read it.

Hacker Culture

Individually, many hackers are antisocial. Their intense interest in computers and programming can become a communication barrier. Left to his or her own devices, a hacker can spend hours working on a computer program while neglecting everything else.

Computer networks gave hackers a way to associate with other people with their same interests. Before the Internet became easily accessible, hackers would set up and visit bulletin board systems (BBS). A hacker could host a bulletin board system on his or her computer and let people dial into the system to send messages, share information, play games and download programs. As hackers found one another, information exchanges increased dramatically.

Some hackers posted their accomplishments on a BBS, boasting about infiltrating secure systems. Often they would upload a document from their victims’ databases to prove their claims. By the early 1990s, law enforcement officials considered hackers an enormous security threat. There seemed to be hundreds of people who could hack into the world’s most secure systems at will [source: Sterling].

There are many Web sites dedicated to hacking. The hacker journal “2600: The Hacker Quarterly” has its own site, complete with a live broadcast section dedicated to hacker topics. The print version is still available on newsstands. Web sites like Hacker.org promote learning and include puzzles and competitions for hackers to test their skills.

When caught — either by law enforcement or corporations — some hackers admit that they could have caused massive problems. Most hackers don’t want to cause trouble; instead, they hack into systems just because they wanted to know how the systems work. To a hacker, a secure system is like Mt. Everest — he or she infiltrates it for the sheer challenge. In the United States, a hacker can get into trouble for just entering a system. The Computer Fraud and Abuse Act outlaws unauthorized access to computer systems [source: Hacking Laws].
Hackers and Crackers

Many computer programmers insist that the word “hacker” applies only to law-abiding enthusiasts who help create programs and applications or improve computer security. Anyone using his or her skills maliciously isn’t a hacker at all, but a cracker.

Crackers infiltrate systems and cause mischief, or worse. Unfortunately, most people outside the hacker community use the word as a negative term because they don’t understand the distinction between hackers and crackers.

Not all hackers try to explore forbidden computer systems. Some use their talents and knowledge to create better software and security measures. In fact, many hackers who once used their skills to break into systems now put that knowledge and ingenuity to use by creating more comprehensive security measures. In a way, the Internet is a battleground between different kinds of hackers — the bad guys, or black hats, who try to infiltrate systems or spread viruses, and the good guys, or white hats, who bolster security systems and develop powerful virus protection software.

Hackers on both sides overwhelmingly support open source software, programs in which the source code is available for anyone to study, copy, distribute and modify. With open source software, hackers can learn from other hackers’ experiences and help make programs work better than they did before. Programs might range from simple applications to complex operating systems like Linux.

There are several annual hacker events, most of which promote responsible behavior. A yearly convention in Las Vegas called DEFCON sees thousands of attendees gather to exchange programs, compete in contests, participate in panel discussions about hacking and computer development and generally promote the pursuit of satisfying curiosity. A similar event called the Chaos Communication Camp combines low-tech living arrangements — most attendees stay in tents — and high-tech conversation and activities.

In the next section, we’ll learn about hackers and legal issues.

Hackers and the Law

In general, most governments aren’t too crazy about hackers. Hackers’ ability to slip in and out of computers undetected, stealing classified information when it amuses them, is enough to give a government official a nightmare. Secret information, or intelligence, is incredibly important. Many government agents won’t take the time to differentiate between a curious hacker who wants to test his skills on an advanced security system and a spy.

Laws reflect this attitude. In the United States, there are several laws forbidding the practice of hacking. Some, like 18 U.S.C. § 1029, concentrate on the creation, distribution and use of codes and devices that give hackers unauthorized access to computer systems. The language of the law only specifies using or creating such a device with the intent to defraud, so an accused hacker could argue he just used the devices to learn how security systems worked.

Another important law is 18 U.S.C. § 1030, part of which forbids unauthorized access to government computers. Even if a hacker just wants to get into the system, he or she could be breaking the law and be punished for accessing a nonpublic government computer [Source: U.S. Department of Justice].

Punishments range from hefty fines to jail time. Minor offenses may earn a hacker as little as six months’ probation, while other offenses can result in a maximum sentence of 20 years in jail. One formula on the Department of Justice’s Web page factors in the financial damage a hacker causes, added to the number of his victims to determine an appropriate punishment [Source: U.S. Department of Justice].
Hacking a Living
Hackers who obey the law can make a good living. Several companies hire hackers to test their security systems for flaws. Hackers can also make their fortunes by creating useful programs and applications, like Stanford University students Larry Page and Sergey Brin. Page and Brin worked together to create a search engine they eventually named Google. Today, they are tied for 26th place on Forbes’ list of the world’s most wealthy billionaires [source: Forbes].

Other countries have similar laws, some much more vague than legislation in the U.S. A recent German law forbids possession of “hacker tools.” Critics say that the law is too broad and that many legitimate applications fall under its vague definition of hacker tools. Some point out that under this legislation, companies would be breaking the law if they hired hackers to look for flaws in their security systems [source: IDG News Service].

Hackers can commit crimes in one country while sitting comfortably in front of their computers on the other side of the world. Therefore, prosecuting a hacker is a complicated process. Law enforcement officials have to petition countries to extradite suspects in order to hold a trial, and this process can take years. One famous case is the United States’ indictment of hacker Gary McKinnon. Since 2002, McKinnon fought extradition charges to the U.S. for hacking into the Department of Defense and NASA computer systems. McKinnon, who hacked from the United Kingdom, defended himself by claiming that he merely pointed out flaws in important security systems. In April 2007, his battle against extradition came to an end when the British courts denied his appeal [Source: BBC News].

In the next section, we’ll look at some famous and notorious hackers.

Famous Hackers

Steve Jobs and Steve Wozniak, founders of Apple Computers, are both hackers. Some of their early exploits even resemble the questionable activities of some malicious hackers. However, both Jobs and Wozniak outgrew their malicious behavior and began concentrating on creating computer hardware and software. Their efforts helped usher in the age of the personal computer — before Apple, computer systems remained the property of large corporations, too expensive and cumbersome for average consumers.

Linus Torvalds, creator of Linux, is another famous honest hacker. His open source operating system is very popular with other hackers. He has helped promote the concept of open source software, showing that when you open information up to everyone, you can reap amazing benefits.

Richard Stallman, also known as “rms,” founded the GNU Project, a free operating system. He promotes the concept of free software and computer access. He works with organizations like the Free Software Foundation and opposes policies like Digital Rights Management.

On the other end of the spectrum are the black hats of the hacking world. At the age of 16, Jonathan James became the first juvenile hacker to get sent to prison. He committed computer intrusions on some very high-profile victims, including NASA and a Defense Threat Reduction Agency server. Online, Jonathan used the nickname (called a handle) “c0mrade.” Originally sentenced to house arrest, James was sent to prison when he violated parole.

Hacker Kevin Mitnick, newly released from the Federal Correctional Institution in Lompoc, California.

Kevin Mitnick gained notoriety in the 1980s as a hacker who allegedly broke into the North American Aerospace Defense Command (NORAD) when he was 17 years old. Mitnick’s reputation seemed to grow with every retelling of his exploits, eventually leading to the rumor that Mitnick had made the FBI’s Most Wanted list. In reality, Mitnick was arrested several times for hacking into secure systems, usually to gain access to powerful computer software.

Kevin Poulsen, or Dark Dante, specialized in hacking phone systems. He’s famous for hacking the phones of a radio station called KIIS-FM. Poulsen’s hack allowed only calls originating from his house to make it through to the station, allowing him to win in various radio contests. Since then, he has turned over a new leaf, and now he’s famous for being a senior editor at Wired magazine.

Adrian Lamo hacked into computer systems using computers at libraries and Internet cafes. He would explore high-profile systems for security flaws, exploit the flaws to hack into the system, and then send a message to the corresponding company, letting them know about the security flaw. Unfortunately for Lamo, he was doing this on his own time rather than as a paid consultant — his activities were illegal. He also snooped around a lot, reading sensitive information and giving himself access to confidential material. He was caught after breaking into the computer system belonging to the New York Times.

It’s likely that there are thousands of hackers active online today, but an accurate count is impossible. Many hackers don’t really know what they are doing — they’re just using dangerous tools they don’t completely understand. Others know what they’re doing so well that they can slip in and out of systems without anyone ever knowing.
