Notable intruder and criminal hackers
Note that many of these have since turned to fully legal hacking.
Jonathan James (a.k.a. comrade) was most notably recognized for the theft of software which controlled the International Space Station's life sustaining elements, as well as intercepting dozens of electronic messages relating to U.S. nuclear activies from the Department of Defense
Eric Corley (a.k.a Emmanuel Goldstein) — Long standing publisher of 2600: The Hacker Quarterly and founder of the H.O.P.E. conferences. He has been part of the hacker community since the late '70s.
Mark Abene (a.k.a. Phiber Optik) — Inspired thousands of teenagers around the country to "study" the internal workings of the United States phone system. One of the founders of the Masters of Deception group.
Dark Avenger — Bulgarian virus writer that invented polymorphic code in 1992 as a mean to circumvent the type of pattern recognition used by Anti-virus software, and nowadays also intrusion detection systems.
John Draper (a.k.a. "Captain Crunch") — Draper is widely credited with evangelizing the use of the 2600 hertz tone generated by whistles distributed in Captain Crunch cereal boxes in the 1970's, and sometimes inaccurately credited with discovering their use. Draper served time in prison for his work, and is believed to have introduced Steve Wozniak to phone phreaking through the 2600hz tone. Draper now develops anti-spam and security software.
Zeljko Vidas a.k.a. Stoney is one of the two people who wrote the viral decomposer Titanic, which has brought down over 70 companies and is one of the most destructable viruses in cyberspace. Known for his fast, smooth operating and his disaperance in cyberspace. Tom Letinov tried to capture him but with no results. Cracked into Croatias police dept. and deleted some records. It is still not known how he did it.
Markus Hess — A West German, he hacked into United States Military sites and collected information for the KGB; he was eventually tracked down by Clifford Stoll.
Adrian Lamo — Lamo surrendered to federal authorities in 2003 after a brief manhunt, and was charged with nontechnical but surprisingly successful intrusions into computer systems at Microsoft, The New York Times, Lexis-Nexis, MCI WorldCom, SBC, Yahoo!, and others. His methods were controversial, and his full-disclosure-by-media practices led some to assert that he was publicity-motivated.
Vladimir Levin — This mathematician allegedly masterminded the Russian hacker gang that tricked Citibank's computers into spitting out $10 million. To this day, the method used is unknown.
Kevin Mitnick — Held in jail without bail for a long period of time. Inspired the Free Kevin movement. Once "the most wanted man in cyberspace," Mitnick went on to be a prolific public speaker, author, and media personality. Mitnick Security Consulting, LLC is a full-service information security consulting firm. Founded by Kevin Mitnick, Mitnick Security Consulting offers a comprehensive range of services to help businesses protect their valuable assets.
Robert Tappan Morris — In 1988 while a Cornell University graduate student was the writer of the first worm, Morris Worm, which used buffer overflows to propagate.
Nahshon Even-Chaim (a.k.a. Phoenix) — Leading member of Australian hacking group The Realm. Targeted US defence and nuclear research computer systems in late 1980s until his capture by Australian Federal Police in 1990. He, and fellow Realm members Richard Jones (a.k.a. Electron) and David Woodcock (a.k.a. Nom) were the world's first computer intruders prosecuted based on evidence gathered from remote computer intercept.
Kevin Poulsen — In 1990 Poulsen took over all telephone lines going into Los Angeles area radio station KIIS-FM to win an automobile in a call-in contest. Poulsen went on to a career in journalism, including several years as editorial director at SecurityFocus.
David L. Smith — In 1999 Smith launched the Melissa Worm, causing $80 million dollars worth of damage to businesses. Originally sentenced to 40 years, he eventually served only 20 months when he agreed to work undercover for the FBI.
Craig Neidorf — In 1990, Neidorf (a co-founder of Phrack) was prosecuted for stealing the E911 document from BellSouth and publicly distributing it online. BellSouth claimed that the document was worth $80,000; they dropped the charges after it was revealed that copies of the document could be freely ordered for 13$.
