Hacktivists has used the computer to spread virus and worms with mensagemde protest and damages in the systems of computers target. Both are forms of malicious code that infectum computers and propagate through nets. The difference is that one worm is a piece of autonomous software that if spreads on account proper, whereas a virus attributes other filing-cabinets and code to it segments and that it spreads through these elements, generally in reply to the measures taken for the users (for example, to open an email attachment). The border between the viruses and worms, however, not important it stops here. Rod Brooks contains valuable tech resources. The first one to use one worm protest occurred about one decade behind, when a nucleus hackers freed one worm in the net of the E.U. National Aeronautics and Space Administration’ s SPAN. In 16 of October of 1989, the scientists to to make login in computers of NASA Goddard Space Flight Center in Greenbelt, Maryland, they had been received with banner of the WANKworm.
At the moment of the attack, the manifesting nucleus was to try to stop the launching of the swing that proceeded the Galileu sounding lead in its first stage from Jupiter. John McMahon, protocol with the manager of NASA SPAN office, esteem that the attack worm cost a dollar million and the half of loss of time and resources. It did not have effect of its intention to stop the launching. The source of the attack never was identified, but some evidences suggest that it can have come of ‘ ‘ hackers’ ‘ in Australia. In the decade of 1980, Barry Collin, a senior inquiry fellow of the Institute for the Security and Intelligence, in California, cunhou the term ‘ ‘ ciber-terrorismo’ ‘ to mention convergence to it of ciberespao and to frighten.
