• Answer:

  Q : How does one hack a computer? A : Usually by exploiting known vulnerabilities that allows the attacker to run unauthorized programs, which in turn gives full access to the victim computer. Q : Why does some one hack a computer? A : These days it is mostly for monetary gain. Organized crime is involved in the spreading and sale of services on illegal botnets for purposes like spam or denial of service attacks. Q : What are computer viruses? Who makes them and how? A : Computer viruses are small bits of program code that attach themselves to other programs and infect as many programs as they can find. Along with viruses there are worms, which infect computers on their own without hitching a ride in another program, and trojans, which pose as useful software, but in fact is malicious software. All of these are collectively called malware. Some of them are written to intentionally cause damage, some cause damage due to bad coding, and some try to trick you into buying things you do not need, or in some cases pay ransom for your own files. Q : How does a computer virus know that what information it has to send and where it has to send the information? A : It usually does not. It opens up the system for remote access, allowing the criminals to browse your computer contents at their leisure. However, some do try to log keystrokes in combination with screen shots when you use services like online banking. Q: How does the hacker get all the information about a computer by hacking it? A: A bit unclear question. The information needed to hack a system is usually gained by scanning ports for unsecured services with known vulnerabilities. Q: Why don’t the government put a ban on computer hacking, if it so bad? A: Hacking a system is considered breaking and entering and is therefore illegal. It is legal where you live ? Q: Why is computer hacking so popular? Is it taught somewhere? A: It is not popular, it is a criminal activity. Most of the so called hackers are clueless kids who download tools they do not understand, and have limited understanding about the damage they do. Q: What is an I.P. address? Is it a secret? How can I know my I.P. address? http://en.wikipedia.org/wiki/Ip_address http://www.whatismyip.com/ Exposing your IP address makes you a target for port scanners, and should be avoided.
