With the development of technology in the twenty-first century, it would be
really difficult to imagine life without computers. They are a source of information, education
and entertainment, but today's world of computers can also be quite frightening and dangerous.
This is because of people who use computers for illegal purposes. They are called hackers.
Hackers spend their time playing with computer data in all parts of cyberspace. Much of what
they do is not dangerous, but sometimes their activities break the law, for example, when they
break into websites, take control of computers or create viruses. They are especially interested in
breaking through the security of military websites. Hackers know how to trick people just using
their programs. They use a 'Trojan Horse’, a program that looks perfectly safe, but actually
contains something destructive. The only way of not getting into trouble is not to open it.
Although they can get serious punishment if they are caught, most hackers still think that what
they do is a game. They often meet at festivals to take part in discussions, share their
experiences, meet other hackers and generally to have a good time. These meetings are
organized in well-known places like Las Vegas or Berlin. However, what the hackers do at such
festivals is a secret and often many of their activities take place at night. Recently, hacking has
started to increase. Hackers are getting into computer systems and stealing or destroying
information. It is certain that there will be a lot more of this high-tech crime in the twenty-first
century.
