July 25, 1995
1. Kevin Mitnick, 31, of Los Angeles. Called the nation's most wanted cybercrook when federal authorities captured him in February in North Carolina after two years on the lam. Government and industry officials claim Mitnick broke into a number of computer systems and copied software valued at millions of dollars. He also allegedly stole 20,000 credit-card numbers, although there was no evidence that he sold the numbers or used them himself. Nicknamed ''Condor,'' Mitnick is a romantic figure in the renegade world of computer hackers. ''Free Mitnick'' T-shirts pop up at hacker conventions.
2. Robert Thomas, 39, of Milpitas, Calif., is serving three years in a federal prison for operating an adult bulletin board service that transmitted pornographic material to a government employee in Memphis, Tenn.
3. Kevin Poulson, 29, of Los Angeles. Was convicted of using a computer to break into the telephone system and rig a radio contest, winning himself a new Porsche. He is awaiting trial in the San Francisco area for possessing a classified defense document.
4. Robert Morris, age unknown. One of the first cybercriminals. In 1988, he crippled the Internet with a computer ''worm'' that replicated itself through the system. The worm shut down 6,200 Internet computers. Morris was sentenced to three years' probation, 400 hours of community service and a $ 10,500 fine.
5. Matthew Thomas, age unknown. Was arrested in April 1994 after using the Internet to send a threatening message to President Clinton. Thomas warned he was going to ''come to Washington and blow your little head off.'' He pleaded guilty and was sentenced to up to five years in prison.
6. Douglas A. Stuper, 33, of suburban Orlando, Fla. Was arrested earlier this month for arranging a tryst with a 15-year-old boy who turned out to be an undercover police officer. Stuper met the ''boy'' in an America Online chatroom, initiating a sexually explicit conversation and transmitting a nude image of himself.
7. Jake Baker, 21, of Boardman, Ohio. The former University of Michigan student was arrested by the FBI in February for using his computer to post a violent and lurid sex fantasy on the Internet, using the real name of a female classmate. Baker spent 29 days in jail but a district judge dismissed the case against him in June. ''The communication which so alarmed the University of Michigan was only a rather savage and tasteless piece of fiction,'' the judge said.
8. Ivy James Lay of Greensboro, N.C. A technician for MCI, he programmed a personal computer to capture more than 50,000 credit-card numbers that he sold to a network of dealers, resulting in more than $ 50 million in fraudulent charges. He was arrested last September.
9. Robert Marriott, 25, and Debra Ache, 38, of Phoenix, Ariz. They bilked $ 27,000 out of Internet users by posting messages that offered collector sets of trading cards for a popular game called ''Magic.'' They charged $ 85 per set but never actually delivered the cards to any customers. There were indicted in December on 22 counts of wire fraud.
10. Jeffrey A. Lors, 30, of Dayton, Ohio, and a 15-year-old boy were arrested for downloading an Internet file and stealing a credit-card number to purchase a $ 4,800 computer from an on-line computer catalog. They were sniffed out by an alert employee of the credit-card company, who noticed that the computer was being shipped to ''Arnold Ziffel'' -- the pig from the old ''Green Acres'' TV show.
