It might sound like very little money to worry about. But that 75 cents was the first clue Stoll had to a much bigger problem--that a hacker had broken into Stoll' s computer system. Who was it？ Stoll spent the next year trying to find out. During that time the hacker used the system in Berkeley as a starting point to break into military computer systems all over the United States.
Stoll had to keep track of the hacker’s activities on the computer without the hacker' s knowing someone was watching him. Stoll even made up huge files of false information so the hacker would have lots to read. When the hacker spent long time reading, the telephone company was able to trace the lines. After a year, the hacker was traced back to his computer--in Germany. He was later caught by the German police.
