n.(Hacker Lingo) One who hacks to find system loopholes, then uses that information to secure the system. Hackers employed with security firms, as well as hacker "watchdog" groups, would be considered whitehats.
Though whitehats have the best of intentions, their effors are often rewarded with lawsuits and criminal charges.

Whitehat was a word previously used to mean that they may use the same way, however they are still the "good guys", and this is no different.

A whitehat hacker is someone who discovers (or attempts) exploits for good use. OpenBSD users/programmers often tend to be whitehats, although still a large number of FreeBSD users/programmers may be whitehats. In comparision I would say more OpenBSD users/programmers are whitehats.

Often when a whitehat finds an exploit, he often informs people as needed. IE: FreeBSD security mail list, OpenBSD security mail list.

At the same time I would assume more Linux users are blackhats due to the large number of pinhead users while most Windows users tend to know even less and primarily stay out of the "game" (this is no game, like blackhats think it is, you just wait until they come upon a server that does remote logging).

Blackhats are often pinheads who have nothing better to do then attack people to prove how "1337" they are.

A sell-out piece of shit in the so-called 'hacker underground'. He loves to believe that he is a 'security enthusiast/security expert', but everyone knows that he's not. Usually steals and leeches code from blaqhats, who are far superior and can actually haq. Whitehats believe in something called 'hacker ethics', which do not exist. This is because of the nature of haqqing. Haqqing was never meant to have ethics way back when, and I know this because I'm not a douchebag or a whitehat sellout piece of fat shit that tries to act like I know shit when I don't. That is the gist of a whitehat. blackhatz unite. let's own all the whitehatz we kan. I'm a pr0ud supp0rt3r 0f pr0j3kt m4yh3m.

Oh, and for all of you kiddies out there, real hackers can use leet speak if they want, idi0ts.
