黑客是因特網(wǎng)上游走的幽靈，是隱蔽的罪犯。他們不僅攻擊個(gè)人電腦系統(tǒng)，而且也攻擊公共電子網(wǎng)絡(luò)系統(tǒng)，從而造成大面積的網(wǎng)絡(luò)癱瘓或設(shè)備損壞。黑客之害，甚于地震、颶風(fēng)等自然災(zāi)害，可謂“罪大惡極”。那么，我們?cè)撊绾螌?duì)付這些藏在暗處的“高手”呢？
Now more and more people buy and sell goods on the Internet. Hackers around the world are interested in this.
Hackers are often young people who love computers greatly. They use computers to get on the Internet, looking for ways to go into computer systems (系統(tǒng)) run by banks, homes and all kinds of offices. If they go into a computer system, they will find other people’s credit cards (信用卡) and try to steal the numbers. With the numbers they can take the money out of the bank.
Hackers often break into your computer system, but it’s difficult to find them. So it is also difficult for you to find the hacker who is taking your money out of the bank. Hackers can get the money from a bank with the credit card number they have got from your computer.
Scientists always ask people who have computers to pay attention to hackers. They also tell people how to fight against the hackers. The answer is to choose clever numbers and change them often and not to show your credit card out to anybody. If you are not careful enough, it’s just like keeping the bank door wide open.
