That list is pretty close to who I'd pick, actually. Except that Shimomura would not make mine - I'd place several others, notably Jamie Zawinski and Guy Steele, above him.
This is more like the "Top Five Best-Known Hackers of All Time". Surely, the real top 5 (with all due respect to RTM), whoever they are, never saw the inside of a courtroom.
"... Mitnick then embarked on a two and a half year coast to coast hacking spree ..."
Mitnick is a good choice for #1 cracker (why do people persist with the 'h' & not the 'cr' ~ http://catb.org/~esr/faqs/hacker-howto.html#what_is ). Mitnick is probably the best known ( http://www.takedown.com/bio/mitnick.html ) but his special area of exploitation is "primarily human" and focus of his book "Art of Deception". This makes him an exceptionally effective cracker, exploiting both man and machine.
While some are good with machines, Mitnick is good with machines & humans cracks ~ http://www.kevinmitnick.com
Acknowledged. But the article doesn't mention Morris as the creator of a social news site for startups, merely a person who caused vast amounts of damage for his own selfish interests. As does Robert's wikipedia entry.
Robert, if you're reading this, do you still (post-sentencing) regret creating the worm?
