问题     It began as a game: high school and college students studying computer technology figured out they could use personal computers to break into telephone company computers and make free, long-distance telephone calls. These young computer wizards soon gained the nickname" hackers".
    Police put the collar on a few hackers,but many went on to even more complex hacking. One hacker was arrested for making illegal telephone calls and later used a jailhouse phone to alter a police officer’s credit records to get back at the officer for arresting him. The hacker also used a computer to alter his college records to give himself better grades. As hackers gained experience,they began invading computers at banks,airlines and other businesses. In one scheme,a hacker instructed an airline’s computer to give him free airplane tickets.
    The U. S. government is worried hackers may break into its sophisticated networks of defense computer. The government’s classified secrets are vulnerable because thousands of government computers are connected by telephone lines that hackers can tap into. In November 1988, a college student tapped into a non classified U. S. Defense Department computer network called Arpanet. The hacker injected a computer program that left copies of itself throughout Arpanet. Some hackers use each "viruses" to destroy all the data in a computer. But in this case,government officials shut down the network before the program reached every computer in the system. Shutting down the system angered many researchers who were using the computers. The hacker turned himself into police and told them how to get his program out of the computer system. He was charged with a crime.
    The incident put the spotlight on computer hacking in the United States. Many companies have hired experts to protect their computers from hackers, and many computer experts now advise companies on how to protect their computers.
    The U. S. government believes foreign governments have hired hackers to try to break into top-secret defense computers. It fears a hacker could inject a virus into military computers that would erase all the data during a war.
    Experts disagree over whether a computer network can ever be safe from hacking. But in the future, some of the most brilliant minds in the U. S. will be working to frustrate the efforts of computer hackers and spies.
