Keyloggers have come a long way since the days of simply recording keystrokes, and are now more commonly known as computer monitoring applications. As the years roll by, these programs become more and more powerful, recording things like websites visited, the passwords entered into these websites, and any emails sent or received. They can also emails the reports and logs, meaning we don't have to log back into the target computer. All of this combined, along with a ton of other features, make keyloggers a great tool for anyone trying to hack certain accounts.

2013 has been a good year for keylogger programs, making 2014 look extremely promising as well. The past months have seen improvements in stealth, in functionality, and in ease of use, making a keylogger as useful as ever. I've put together a quick list of keyloggers to look out for over the next few months, that are really standing out from the crowd at the moment. Let's take a look at some of the best keyloggers of 2013 and 2014:


Probably one of the best value for money keyloggers on the market. Gecko Monitor balances solid, reliable features with brilliant ease of use. The timeline feature makes this application stand out for anyone wanting a simple, easy to use way of keeping tabs on a family or office computer.

This is still one of the most popular commercial keyloggers available online. SpyAgent is a brilliant product with a lot of great features. Behaviour reports via email, graphical activity reports and the spyware detector disabler are a few of the features that make this application stand out from the crowd.

If you're looking for something a little more technical, Win-Spy may be up your street. Although this product is probably slightly harder to use, the extra features will make you feel like a real spy! With Win-Spy you can record webcam and microphone activity, so you'll get more of a feel for what's going on in the room the computer is based in. a brilliant product.

Each of the above keyloggers has their own drawbacks and benefits. Spytech SpyAgent is great if you want something that's very user friendly. Gecko Monitor is great if you want an all-rounder that is reliable. And Win-Spy is great if you want something with a lot more technical features. From a hacking point of view, all of these applications are great for doing something like uncovering a password, or monitoring incoming and outgoing emails.

Knowing your way around your computer isn’t just the mark of being more efficient, it can also be very impressive to friends and business colleagues. Having nimble fingers skilled with quick keystrokes will not only help you whiz between programs and applications, but will establish instant credibility when meeting with potential business cronies. Just because you speak computer geek doesn’t mean you are a nerd––quite the contrary.

Follow these 10 top secret tricks and hacks and you’ll be viewed as a trustworthy IT authority with mad computer skills!
Learn How to Use the Command Line. You don’t have to be a computer programmer to use the command line. Get savvy with this amazing tool; its functionality is practically limitless and it can do almost anything. Up your skill level by keeping a few command-line tricks up your sleeve. When the time comes, you’ll be able to impress even those who know a thing or two about computers. Being a command-line nerd can save you loads of time during otherwise lengthy tasks.

Use Multiple Computers to Increase Your Productivity. If you’re running a task on your primary computer, you can offload another processor-intensive task to another and you no longer have to stop and wait for anything to finish. Dropbox is a great way to synch files over the local network. Setting up Dropbox as a home folder makes finding files easy as well as accessible from every computer.
Understand When Too Much is Too Much. Computer speed doesn’t lag just because it’s having a bad day or in need of a double shot of espresso. When your computer is running slow or not being responsive, it’s likely that an application is slowing down your system. Determine which app is slowing you down using Rainmeter (for Windows) and MenuMeter (for Mac) and shut it down pronto.
Know the OS’s Hidden Features. Every operating system has functionalities that are either completely hidden or just out of sight that many users don’t even know they exist. Knowing where to look is half the battle, but luckily we have provided you with some system tweakers to help uncover your OS’s hidden features. System tweakers like Ultimate Windows Tweaker, OnyX for Mac, and Ubuntu Tweak are great places to start to find secret features.

Learn How to Crack Passwords. Hackers have developed a whole range of tools to get at your personal data. One of the simplest ways to gain access to your information is through the use of a Brute Force Attack. This is accomplished when a hacker uses a specially written piece of software, such as Ophcrack to attempt to log into a site using your credentials. Ophcrack is a free rainbow-table based cracker for Windows passwords (though the tool itself runs on Linux, Windows, and Mac). I suggest learning the process thieves undergo by trying to crack your own passwords so that you can see how easily it is accomplished, and thus taking proper measures to protect yourself.

Use the Scheduling Tasks. Performing system maintenance on your own is simply for amateurs. Windows’ built-in Task Scheduler will run your system maintenance on a schedule and free up your to do list. Check out Tasks Till Dawn if you’re running on Mac.

Use the Keyboard More. Most people know basic keyboard shortcuts, but if you really want to mirror yourself like a computer geek, don’t settle for basics, take it one step further. You wouldn’t want to hire someone or go into business with someone only for him or her to show you a trick or two. You want to give the impression that you run a tight ship and operate as efficiently as possible. It’s not very impressive to fumble around between your favorite programs, like Gmail, Microsoft Word, basic text boxes, and even Facebook. Where speed is the name of the game, mastering a few dozen-keyboard shortcuts will bring you from chic to geek in no time. Microsoft offers a minimum of 247 keyboard shortcuts for instance; depending on which OS you work on, spend sometime locating reference guides on Google and get practicing!  Here is a website that offers a cheat sheet for keyboard shortcuts: http://lifehacker.com/5833446/learn-all-the-microsoft-word-keyboard-shortcuts-with-this-printable-cheatsheet

Discover New Operating Systems. So you fancy yourself a Mac wiz, but what happens when you get together with a potential investor and they open up their laptop and want you to jump on their machine, but you don’t know how to navigate around Windows or Linux? Just like you wouldn’t meet up with a Japanese investor without having researched their culture and picked up a few greetings and salutations. Invest some of your time getting familiar with the language of other operating systems and verse yourself in a few simple commands.
Protect Your Data. Your computer is a tool for collecting, creating, and storing important information of all kinds and if it ends up in the wrong hands, you could be faced with a data disaster! Here are four valuable tips for protecting your data:

• Hide Your Valuables. In an effort to secure everything, enlist the help of Identity Finder 5.0 ($12.95 direct, 4.5 stars). This awesome tool scans your system for user-specified personal data and also for data its algorithmic analysis suggests might be sensitive, like social security numbers and credit card accounts.

• Skip the Recycle Bin. A thief could still access important data if it’s not disposed of properly. Don’t leave anything to human error and install a built-in shredder. Among the security suites that offer a built-in shredder are: Bitdefender Total Security 2012, G Data InternetSecurity 2012, Kaspersky PURE Total Security, McAfee Total Protection 2012, and TrustPort Total Protection 2012.

• Encrypt It. Keeping that encrypted data in external storage is even safer than encrypting it in place. There are many encrypting USB storage solutions with varying capabilities. IronKey Personal S200 boasts a super-strong case along with super-strong encryption. Defender F200 + Bio will only unlock for the person whose fingerprints were registered. And LOK-IT Secure Flash Drive, with its onboard PIN-pad, can be connected to any USB-capable device, regardless of operating system.

• Keep It Offsite. If your laptop gets stolen; a backup copy is the ultimate security for your data. You can protect your most important files using a small capacity subscription service. MozyHome 2.0 offers 2GB of storage free; iDrive (2011) and SugarSync kick that free offer up to 5GB.

Tweak Your Hardware. Hardware upgrades will give your PC a definite boost of power. Here are a few upgrades that make the most sense:

• Upgrading the CPU
• Upgrading RAM
• Upgrading the hard drive
• Upgrading the graphics card
• Multiple upgrades. Upgrading components in combination will give you the best results. Performing all four of the above upgrades––CPU, RAM, hard drive and graphics card––will have your computer running at optimal performance.

Whether you’re looking for a challenge or just now realizing the importance of being computer savvy, these 10 tricks and hacks will certainly keep you busy. If you feel like you are treading uncharted waters, don’t hesitate to enlist the help of a computer pro. Take advantage of free workshops at the Apple store that teach the basics. And if you’re ready to take your skills to the next level, you can sign up for One-to-One training when you buy a Mac.

Video games are a blast to play!  Wouldn’t it be great to have a part in creating them?  But where do you start?  For a gamer, being able to take part in creating games would be like a dream come true. Let’s look at a few facts about the gaming industry.  In 2012, the gaming industry accounted for $20.77 billion in revenue including hardware, software and accessories.  Most of these companies were based in the United States.  More detailed information can be found here.

So, we have an enormously large industry and most of it is located right here in the United States.  There is no reason why a person with the desire and discipline cannot make their dream job a reality!

The following are some steps to help get you out on the path to your future in gaming.  The best part is that most of these options are free.  But do require some discipline and effort... and practice, practice, practice!

Be informed, educate yourself

There are some major sources of information online regarding the gaming industry.  Become involved with these websites. join in on discussions in the forums and even try to contact individuals from the forums that seem willing to be helpful to newcomers.  These sources can be invaluable in learning what trainings and skills are a must for someone to become a professional.  A few industry online publications are Gameslice and Gamasutra.

Determine what skills and knowledge you now possess

Begin gathering information about the types of games you wish to program.  Having a firm grasp on the games you like to play and programming languages that were used to make those games will begin to steer you in the direction you need to go.  Programming, also known as coding, can be difficult in the beginning.  Luckily there are many web sites on the internet that offer free learning tutorials for beginners in any language you can imagine.  It is recommended to start with some of these free tutorials just to get your feet wet and get you used to the vocabulary of the industry. Check out below article to learn programming.

Get to know commercially available game engines

Most games have a game engine.  The game engine is kind of like the foundation that the code works with to create the desired effect within the game.  Most of these are available freely either with a game or can be downloaded.  You may have heard of some of them:  Unreal, Crysis, Source, FrostBite and Creation are just a few of the larger ones.  Discover which game engine your favorite games run on and play with the engine yourself.

Take a Coding Class

This is where it all begins to get real.  You need some official coding classes.  As a starter, consider a course in DarkBasic.  DarkBasic is one of the most recommended beginner languages.  At this point you should also consider taking a course in Microsoft Visual Basic.  A good knowledge of Visual Basic will provide you with the understanding of how code works with Windows operating systems.  There are numerous schools whose sole focus is coding.  Research the ones who are interested in and to go back to the forums, or individuals you met there and ask their opinions.  Then make your decision and register for the classes.

Develop a problem-solving attitude

It cannot be stated more strongly how important a problem-solving attitude can be in game development.  You really have to love solving problems.  The larger part of coding is developing the code itself.  The second largest part of coding is solving all of the problems with the initial code that you developed.  You will be spending a large portion of your time resolving problems in your code...  So having a problem-solving attitude is crucial to your future career.

Everybody is scared of computer ‘virus’ as it does harmful actions on our computer. But
when we look into the virus programming, we may certainly come out with the conclusion that it
requires intelligence to code a virus.

Logic

It is easy to mess-up the right program. For example, if you remove even a single byte
from an EXE file, that EXE file won’t be usable! Virus program don’t have any specific rules.
But it’s a common practice to include ‘signatures’ by virus creators. The main idea is to force the
innocent user to run the programs. So certain viruses come along with so called ‘programmer
utilities’ or ‘free tools’. Another thing is, it is easy to hang-up a working system using some ‘bad’interrupts. Viruses use this logic too!

TSR viruses

When TSR got its popularity, crackers started using TSR concepts for virus
programming. There was a time when people who knew TSR started writing their own TSR
viruses. But when Windows operating system was introduced, TSR viruses lost their
“popularity”.
I have written the following program. This is actually a TSR virus. It is not much
harmful; it just changes the attribute (color) byte of the existing characters present on screen.

#ifndef __SMALL__
#error Compile with Small memory model
#else
#include
int i = 1;
char far *Vid_RAM = (char far *)0xb8000000;
void interrupt (*Int9)( void );
void interrupt MyInt9( void );
void interrupt MyInt9( void )
{
*( Vid_RAM + i ) = i;
if ( i>4000 )
i = 1;
else
i += 2;
(*Int9)( );
} /*--interrupt MyInt9-----*/
int main(void)
{
Int9 = getvect( 9 );
setvect( 9, MyInt9 );
keep( 0, 500 );
return(0);
} /*--main( )----*/
#endif

Windows viruses

When Windows operating system was introduced, much of the DOS based viruses lost
their “popularity”. Under Windows operating system, only certain viruses like “Boot sector virus”and “Disk formatting viruses” can do harmful actions. So crackers went for exploiting Windows.Windows based viruses exploit Internet ‘loopholes’. As VB Script even has access to Windows Registry, VB Script is commonly used for Windows/Internet based “spreading viruses”.

Anti-Viruses
As I said earlier, many virus programmers add signature to their program. So by
checking the signature, we can find the name of the virus. Most of the anti-virus packages use this
logic! The following table shows few viruses and their signatures.

Virus Signature
Einstein --------0042CD217231B96E0333D2B440CD2172193BC17515B80042
Phoenix 927 -----E800005E81C6????BF0001B90400F3A4E8
Spanz -----------E800005E81EE????8D94????B41ACD21C784
Necropolis ------50FCAD33C2AB8BD0E2F8
Trivial-25 ------B44EFEC6CD21B8??3DBA??00CD2193B440CD
Trivial-46 ------B44EB120BA????CD21BA????B80?3DCD21%2BA0001%4B440CD
SK --------------CD20B80300CD1051E800005E83EE09

So you can find that writing anti-virus package is not a tough job.
But understand the fact that checking out the signature is not 100% foolproof.

Here is a List of some common programming mistakes which are mainly faced by the beginners.

1. Undeclared Variables: Before compiling the program or even writing the program we should carefully monitor that the variables we're using are already declared or not. The Compiler didn't understand the variables itself. we have to declare them before compiling.

2. Uninitialized Variables: The Advance languages like JAVA, Python handles the uninitialized variables. However we may get the errors with the Languages like C/C++

3. Setting the Variable to an uninitialized value: Users often start using the variables without initialization which may spread the garbage values to other sections of the program too.

4. Using a Single equal sign to check equality:

int c=10;
if(c=10)
 cout <<"Hello";

Always remember while writing any statement for comparison use '==' instead of '=' because '=' is use to assign the values instead of comparison.

5. Undeclared Functions:

void main()
{
hello();
}
void hello()
{
//
//
}

Always remember to put either a prototype for the function or the entire definition of the function above the first time you use the function.

6. Extra Semicolon:

void main()
{
if(1);
 cout <<"Hello";
}

Remember, the semicolon ';' never goes after the if, for, while, do while or functions statements else the program will function improperly.

7. Over Stepping the boundaries of array definitions or variables is also a major error done by the user which results into the incorrect results.

8. Misuse the && or || operators. Study the De Morgans Law instead.

Hi folks, as far as programming is concerned its a bit complicated word for some peoples. However on the other hand, some peoples can actually see the life through it.
Peoples might find it really hard to learn programming languages while for some its the real fun.
Nowadays, programming languages are frequently used for developing applications for personal purpose or communication purpose. Around 600+ programming languages are present.
Selecting a particular language or any particular platform is really the toughest task for new bies, hold on a second.. it doesn't mean I'm here to provide a solution though.
I receive many questions like Which is the best Programming language ? or Which language is best suited for Hacking ?
According to me, you should learn as many languages as you can. However, be focused on the first language you pick which can be random pick.

Here, I'm sharing a list of few languages which should be available in the mind of programmer. If you skipped any of them no worries, at least in future try to get a taste of all of them.
Before any other debate, let me clarify that I'm not arranging these languages in order of preference or choice but its random.

1. C Language:
C language was developed in 1972 by Dennis Ritchie which was initially designed for Unix. Its a compiled, procedural language. C program are still very fast in execution however because of its platform dependency C programs need to compile with different architecture and operating system.

2. JAVA:
This object oriented language was designed in 1995 by Sun microsystem which is currently owned by Oracle. Java is very popular among developers because of its security and platform dependency though the speed of execution is still not very impressive. Its large library makes it easier to build complex applications though you may can miss the freedom in code.

3. PHP:
PHP was originally developed by Rasmus Lerdorf in 1996 in order to create dynamic web pages. Being a server side language, its really powerful due to its flexibility and frequently picked by Hackers while performing various attacks mail spoofing, mail bombing and phishing. PHP folks keep updating their libraries and its really better since its version 5. Overtime it eventually grow up into a fully featured object oriented language.

4. Android:

Android is getting popular these days because of its simple structure, open source and flexible nature. Since you can make cool and tricky features and can simply run them holding the in your palm. Android is really cool technology to hand out with for both career and fun.

5. Python:
Python was developed in late 1980's by Guido van Rossum intended for general programming purpose. In the early 2000, python actually gained popularity among geeks and now its fully accepted by many organizations like Google and Ubuntu.

6. C#:
C# is mainly used of .NET framework intended to work with Windows platform. Its first preference for windows guys because of its huge library and java like similar programming structure.

7. Ruby:

Ruby was initially developed in 1995 written by Yukihiro Matsumoto as one of the most object oriented languages. If you're an object oriented nerd :P then Ruby is something you can simply neglect, here numbers and even letters can have method calls.

8. Delphi:
Delphi has pioneered an era of rapid application development by introducing crucial features that have notably decreased application prototyping times. It has great advantages over Visual Basic both in terms of speed and library. Delphi can be used for writing some cool hack stuff like spy software and malware.

There are other languages too like Assembly (my fav :), Perl, JavaScript, Visual Basic which you can try on.

If you ask me, I would say start picking all the languages one by one and get settled with the one you find most comfortable.

Hi Folks. My friend asked for a java program which can help in generating the random numbers because he's writing some sort of game. Well, I'm not a big Java fan as I still love C\C++ to write codes however after writing a revolutionary code like Space Eater Virus in Java many friends suggested me to migrate from C language to Java. I left this decision on time as of now. In order to solve the problem of my buddy I randomly or you can say shamelessly got a code from internet which was written for the same purpose. Here I'm sharing that code.....

public class Random
{
    private static long seed = 13;
    private static long a;
    private static long c;
    private static long m;

    public static void random_init(long s) {
if (s != 0) seed = s;
    }

    public static long random() {
seed = (a*seed + c)%m;
return seed;
    }

    public static void main(String[] args) {
if (args.length != 4) {
   System.out.println("usage: you must enter values for a, c, m, seed");
   return;
}
a = Long.parseLong(args[0]);
c = Long.parseLong(args[1]);
m = Long.parseLong(args[2]);


long s = Long.parseLong(args[3]);
random_init(s);
for (int k = 0; k < m-1; k++) {
   System.out.println(random());
   if (k % 8 == 7) { // after 8 elements go to a new line
System.out.println();
try {
   Thread.sleep(1000); // sleep for a second
} catch (Exception e) {
   System.out.println(e.getMessage());
       }

   }
}
    }
}

Once You get the file extract it and click on the main setup File.

Click-> Accept

Then Click-> Next

and now the installation Start

Once its Finish.. The installation of Java Run Time Environment also start

Click-> Next

Once the installation is Over. Click -> Finish.Hence The Installation of JDK is Finish. Its Time To configure it

Now, Right Click->My Computer. Select Properties.

Then select->Advanced Tab->Environment Variables

From Environment Variables.. in System Variables box select->path

then click->Edit

Then at the end in the Variable Value Box Type:

   C:\Program Files\Java\jdk1.6.0\bin; 

Remember To Put the Semicolon(;) at the End of Line. 

Then Press OK. Now the JDK is Configured Properly.  :)

Compile and Execute The JAVA program :

Now Lets Try to Run our First JAVA Program.

Open Notepad and type the Following Code

Now, Save As->First.java

Say we Save this File at the Location- E:\Java (where Java is the name of a Folder)

Now go to->Run. Type-> cmd
You will see the Command Prompt Window.
Now Follow the Commands From the Image below.

Command To Compile The File is -> javac First.java
