TOP 7 MOST FAMOUS HACKER OF ALL TIME

 Black Hat Crackers
The Internet abounds with hackers, known as crackers or “black hats,” who work to exploit computer systems. They are the ones you’ve seen on the news being hauled away for cybercrimes. Some of them do it for fun and curiosity, while others are looking for personal gain. In this section we profile five of the most famous and interesting “black hat” hackers.

1. Jonathan James: James gained notoriety when he became the first juvenile to be sent to prison for hacking. He was sentenced at 16 years old. In an anonymous PBS interview, he professes, “I was just looking around, playing around. What was fun for me was a challenge to see what I could pull off.”
   James’s major intrusions targeted high-profile organizations. He installed a backdoor into a Defense Threat Reduction Agency server. The DTRA is an agency of the Department of Defense charged with reducing the threat to the U.S. and its allies from nuclear, biological, chemical, conventional and special weapons. The backdoor he created enabled him to view sensitive emails and capture employee usernames and passwords.
   James also cracked into NASA computers, stealing software worth approximately $1.7 million. According to the Department of Justice, “The software supported the International Space Station’s physical environment, including control of the temperature and humidity within the living space.” NASA was forced to shut down its computer systems, ultimately racking up a $41,000 cost. James explained that he downloaded the code to supplement his studies on C programming, but contended, “The code itself was crappy . . . certainly not worth $1.7 million like they claimed.”
   Given the extent of his intrusions, if James, also known as “c0mrade,” had been an adult he likely would have served at least 10 years. Instead, he was banned from recreational computer use and was slated to serve a six-month sentence under house arrest with probation. However, he served six months in prison for violation of parole. Today, James asserts that he’s learned his lesson and might start a computer security company.
2. Adrian Lamo: Lamo’s claim to fame is his break-ins at major organizations like The New York Times and Microsoft. Dubbed the “homeless hacker,” he used Internet connections at Kinko’s, coffee shops and libraries to do his intrusions. In a profile article, “He Hacks by Day, Squats by Night,” Lamo reflects, “I have a laptop in Pittsburgh, a change of clothes in D.C. It kind of redefines the term multi-jurisdictional.”
   Lamo’s intrusions consisted mainly of penetration testing, in which he found flaws in security, exploited them and then informed companies of their shortcomings. His hits include Yahoo!, Bank of America, Citigroup and Cingular. When white hat hackers are hired by companies to do penetration testing, it’s legal. What Lamo did is not.
   When he broke into The New York Times’ intranet, things got serious. He added himself to a list of experts and viewed personal information on contributors, including Social Security numbers. Lamo also hacked into The Times’ LexisNexis account to research high-profile subject matter.
   For his intrusion at The New York Times, Lamo was ordered to pay approximately $65,000 in restitution. He was also sentenced to six months of home confinement and two years of probation, which expired January 16, 2007. Lamo is currently working as an award-winning journalist and public speaker.
3. Kevin Mitnick: A self-proclaimed “hacker poster boy,” Mitnick went through a highly publicized pursuit by authorities. His mischief was hyped by the media but his actual offenses may be less notable than his notoriety suggests. The Department of Justice describes him as “the most wanted computer criminal in United States history.” His exploits were detailed in two movies: Freedom Downtime and Takedown.
   Mitnick had a bit of hacking experience before committing the offenses that made him famous. He started out exploiting the Los Angeles bus punch card system to get free rides. Then, like Apple co-founder Steve Wozniak, dabbled in phone phreaking. Although there were numerous offenses, Mitnick was ultimately convicted for breaking into the Digital Equipment Corporation’s computer network and stealing software.
   Mitnick’s mischief got serious when he went on a two and a half year “coast-to-coast hacking spree.” The CNN article, “Legendary computer hacker released from prison,” explains that “he hacked into computers, stole corporate secrets, scrambled phone networks and broke into the national defense warning system.” He then hacked into computer expert and fellow hacker Tsutomu Shimomura’s home computer, which led to his undoing.
   Today, Mitnick has been able to move past his role as a black hat hacker and become a productive member of society. He served five years, about 8 months of it in solitary confinement, and is now a computer security consultant, author and speaker.
4. Kevin Poulsen: Also known as Dark Dante, Poulsen gained recognition for his hack of LA radio’s KIIS-FM phone lines, which earned him a brand new Porsche, among other items. Law enforcement dubbed him “the Hannibal Lecter of computer crime.”
   Authorities began to pursue Poulsen after he hacked into a federal investigation database. During this pursuit, he further drew the ire of the FBI by hacking into federal computers for wiretap information.
   His hacking specialty, however, revolved around telephones. Poulsen’s most famous hack, KIIS-FM, was accomplished by taking over all of the station’s phone lines. In a related feat, Poulsen also “reactivated old Yellow Page escort telephone numbers for an acquaintance who then ran a virtual escort agency.” Later, when his photo came up on the show Unsolved Mysteries, 1-800 phone lines for the program crashed. Ultimately, Poulsen was captured in a supermarket and served a sentence of five years.
   Since serving time, Poulsen has worked as a journalist. He is now a senior editor for Wired News. His most prominent article details his work on identifying 744 sex offenders with MySpace profiles

White Hat Hackers
Hackers that use their skills for good are classified as “white hat.” These white hats often work as certified “Ethical Hackers,” hired by companies to test the integrity of their systems. Others, operate without company permission by bending but not breaking laws and in the process have created some really cool stuff. In this section we profile five white hat hackers and the technologies they have developed.

1. Stephen Wozniak: “Woz” is famous for being the “other Steve” of Apple. Wozniak, along with current Apple CEO Steve Jobs, co-founded Apple Computer. He has been awarded with the National Medal of Technology as well as honorary doctorates from Kettering University and Nova Southeastern University. Additionally, Woz was inducted into the National Inventors Hall of Fame in September 2000.
   Woz got his start in hacking making blue boxes, devices that bypass telephone-switching mechanisms to make free long-distance calls. After reading an article about phone phreaking in Esquire, Wozniak called up his buddy Jobs. The pair did research on frequencies, then built and sold blue boxes to their classmates in college. Wozniak even used a blue box to call the Pope while pretending to be Henry Kissinger.
   Wozniak dropped out of college and came up with the computer that eventually made him famous. Jobs had the bright idea to sell the computer as a fully assembled PC board. The Steves sold Wozniak’s cherished scientific calculator and Jobs’ VW van for capital and got to work assembling prototypes in Jobs’ garage. Wozniak designed the hardware and most of the software. In the Letters section of Woz.org, he recalls doing “what Ed Roberts and Bill Gates and Paul Allen did and tons more, with no help.” Wozniak and Jobs sold the first 100 of the Apple I to a local dealer for $666.66 each.
   Woz no longer works full time for Apple, focusing primarily on philanthropy instead. Most notable is his function as fairy godfather to the Los Gatos, Calif. School District. “Wozniak ‘adopted’ the Los Gatos School District, providing students and teachers with hands-on teaching and donations of state-of-the-art technology equipment.”
2. Tim Berners-Lee: Berners-Lee is famed as the inventor of the World Wide Web, the system that we use to access sites, documents and files on the Internet. He has received numerous recognitions, most notably the Millennium Technology Prize.
   While a student at Oxford University, Berners-Lee was caught hacking access with a friend and subsequently banned from University computers. w3.org reports, “Whilst [at Oxford], he built his first computer with a soldering iron, TTL gates, an M6800 processor and an old television.” Technological innovation seems to have run in his genes, as Berners-Lee’s parents were mathematicians who worked on the Manchester Mark1, one of the earliest electronic computers.
   While working with CERN, a European nuclear research organization, Berners-Lee created a hypertext prototype system that helped researchers share and update information easily. He later realized that hypertext could be joined with the Internet. Berners-Lee recounts how he put them together: “I just had to take the hypertext idea and connect it to the TCP and DNS ideas and – ta-da! – the World Wide Web.”
   Since his creation of the World Wide Web, Berners-Lee founded the World Wide Web Consortium at MIT. The W3C describes itself as “an international consortium where Member organizations, a full-time staff and the public work together to develop Web standards.” Berners-Lee’s World Wide Web idea, as well as standards from the W3C, is distributed freely with no patent or royalties due.
3. Linus Torvalds: Torvalds fathered Linux, the very popular Unix-based operating system. He calls himself “an engineer,” and has said that his aspirations are simple, “I just want to have fun making the best damn operating system I can.”
   Torvalds got his start in computers with a Commodore VIC-20, an 8-bit home computer. He then moved on to a Sinclair QL. Wikipedia reports that he modified the Sinclair “extensively, especially its operating system.” Specifically, Torvalds hacks included “an assembler and a text editor…as well as a few games.”
   Torvalds created the Linux kernel in 1991, using the Minix operating system as inspiration. He started with a task switcher in Intel 80386 assembly and a terminal driver. After that, he put out a call for others to contribute code, which they did. Currently, only about 2 percent of the current Linux kernel is written by Torvalds himself. The success of this public invitation to contribute code for Linux is touted as one of the most prominent examples of free/open source software.
   Currently, Torvalds serves as the Linux ringleader, coordinating the code that volunteer programmers contribute to the kernel. He has had an asteroid named after him and received honorary doctorates from Stockholm University and University of Helsinki. He was also featured in Time Magazine’s “60 Years of Heroes.”
