Using international phone links, a group of West German hackers took repeated strolls through NASA computers last summer, as well as through several U.S. military networks. NASA spent three months changing passwords and clearing out "trap door" programs that the intruders had planted to give them access. Another German hacker spent nearly two years cruising through unclassified data in U.S. Defense Department and other research computers around the world until he was stopped last year. And last May, NASA’s Jet Propulsion Laboratory in Pasadena, California, was invaded by hackers yet to be identified. Even companies with good security have run into a new problem: the computer virus. Like micro-organisms, these replicate and spread. They’re tiny bits of software, often quickly written，that hide in larger programs and then pounce unpredictably.

答案：去年夏天，一群西德电脑黑客通过使用国际电话网络，多次在美国宇航局的电脑上漫游，还进入了好几家美国军用网络。后来宇航局花了三个月的时间，更换口令，清除这帮入侵者设置的‘迷藏’式进入程序。还有一个德国黑客两年多来，一直在浏览美国国防部的非保密情报和世界其它研究资料，去年才被禁止。去年五月，位于加州帕萨迪纳的宇航局喷气推力实验室受到黑客入侵，至今仍未水落石出。那些防范严格的公司也碰到了一个新的难题：电脑病毒。它们像微生物一样，能够繁衍，能够扩散。这些匆忙写就的微型软件，藏身在大块的程序当中，神不知鬼不觉地发动攻击。
