Phiber Optik was the leader of the Master’s of Deception (MoD) hackers ring in New York City in the 1980’s/early 1990’s.  Allegedly he master-minded the Martin Luther King day crash of AT&T’s national phone service in 1990.  Known for his daring actions and media stunts he appeared or was interviewed in many publications including Harper’s, Esquire, and the New York Times.  Don’t worry…he got busted.  Turk 182!

In 1991 Robert Morris became the first individual convicted for violating the 1986 Federal Computer Fraud and Abuse Act.  He created an internet worm as part of a graduate school project whose sole purpose was to expose security vulnerabilities in networks so that network administrators could pro-actively fix any security holes.  Unfortunately the project went amiss and computer networks crashed left and right when it was released errantly on the Internet.  In hind-sight he should have kept it a little better under control.  It just goes to show you that good intentions also get punished… “ignorance of the law is no excuse.” 

John Draper, a.k.a. “Captain Crunch,” gained notoriety in the 1970’s as a “phreaker” (phone hacker) when he figured out how pay phones work.  He discovered when you put a dime in a payphone (calls in the 1970’s used to be 10 cents) the telephone had an electromechanical converter that sent a 2600-hertz tone to the phone company as a “signal” that a dime had been inserted into the telephone.  About the same time he discovered that a whistle given out in boxes of Captain Crunch cereal emitted a frequency of 2600 hertz.  Aha!  He then could make telephone calls essentially for free.  Shortly thereafter he also discovered the “Oscar Meyer Wiener” whistles also emitted a 2600-hertz frequency.  Today’s pay phones still work on the same premises.  The 2600-hertz frequency was also used to derive the name for “2600” magazine, better known as “The Hacker Quarterly” started by Emmanuel Goldstein in 1984

In 1990 Kevin Paulsen, a.k.a. “dark dante,” used his knowledge of the phone company and their operations to seize control of all telephone lines into KIIS-FM in Los Angeles.  Then it was easy for him to be the 102nd caller and win the shiny Porche.  He also has been photographed picking locks to phone company property and admitted to hacking into the FBI to obtain lists of companies that are owned and operated by the FBI.

Jason Allen Diekman, a.k.a. “Shadow Knight” or “Dark Lord,” was charged with hacking into Nasa, Oregon State Univeristy, and a San Francisco area ISP in 2002.  He was sentenced to 21 months in Federal Prison, ordered to pay restitution of $87,736.29, and will have 3 years of probation, which includes no computer accessing.  Apparently he used stolen credit card numbers to transfer money through Western Union and to try buying equipment from NASA’s Jet Propulsion Laboratory.  While free on bail from charges the “defendant” (use whatever word you want there) hacked into several other university computer systems.  Boy this one is a case study in stupidity 101.  Even “geniuses” do not always have “common sense.”  Won’t shower time be fun for him too?

Geoffrey Osowski and Wilson Tang  There are not hackers !!!!!!!

they were accountants who worked for CISCO (yes…them!).  They were charged with computer-related crimes when, being accountants, they illegally issued almost $8,000,000 in CISCO stock to themselves.  They each received 34 months in prison, 36 months of probation, and restitution of almost $8,000,000.  The moral of the story is don’t try this at home!

Patrice Williams was sent to prison in 2002 after she, and a partner (Makeebrah Turner), hacked into the Chase Financial Corporation.  Apparently this dastardly duo stole credit card numbers and used them to purchase about $600,000 worth of merchandise on 68 different accounts.  They also “distributed” some of those numbers to someone else in Georgia who, in turn, purchased about $100,000.  The brain trust plea-bargained down to a one-year and a day prison term in return for a guilty plea.

Kuasha , In 2006 first Hack his colleagues PC but didn't caught anymore.......llk

Great post niz...

 " Dont learn hacking..  learn abt network security "

hacking isnt stupid thing . u have to have enough knowledge to be a hacker .. there is two kind of hackers .. actual hackers ( who use brain and self programming and networking  knowledge) , second script kiddi hackerz ( use script /programs ) ..

 script kiddiz can hack individualz by trick or using script / program , but never ever able to hack corporate networks ..

elite class hackers ... use unix / linux .. N most of them are networking guru .
