We all are generally aware of the term virus, whenever we speak about IT security. Yes, they are a huge threat to the computers and the data stored in them. But have you ever paid attention to the various awful practices done by techies. Such technocrats are called as hacker.
Hackers are said to be people with a good brain going in the wrong direction. They have a bad reputation, all because of media. This actually has been used to call technicians who use the PC to do all sorts of spiteful things like irritating users, anti-social activities like information stealing, forgery, scandalizing companies, etc. These are also believed to go to the extent of entering security services and destroying economy. However, hackers are not very bad.
Hackers are programmers who can notice the internal codes. (They are genius brains). They are curious people who can go up to any level to gain knowledge and get to know how a system works etc. But how do hackers work? They take an advantage of the known bug or errors in popular applications. They claim to give you repair patches that you can down load from the net. Most of these patches have spyware hidden in them. Now most people accept this. This creates a gateway for the hackers to look in to the computer and access data unauthorized. Once they have entered the system virtually they can exploit it any how.
Here is how these hackers do their work. They use certain tools to do their job. Below are listed their methodologies.
Key store record: The spyware, which are installed on the PC, are used to monitor the keystrokes made by the user. This review is mostly converted into a text file which the hackers use to access important data or even use the victim's identity to infiltrate on non accessible sites.
Passwords hacking: One can hack anyone's password. There are many ways in which one can do this. This need not mean that some one actually sees you typing it. Instead it ranges right from wild guesses to using algorithms. The algorithms create a list of possible combinations of numeric and character data. There are two types of trial and error methods viz. brute force attack or dictionary attack.
To avoid unauthorized entry to your PC here are a few simple tips. At first, never download any patch or a program if the source is unknown. Keep changing your passwords often. Better to change your password whenever you suspect that it is stolen. Use a good antivirus that eliminates spyware and malwares.
