a trojan horse is not a virus
But Macs don't get viruses. Let me ask my Mac overlords what this contradiction could mean...
They say that it's all an illusion. Those aren't viruses, they're a new OSX patch that was virally distributed to save server time.
anyone can write a destructive program, call it "cracked version of some-other-program" and trick a user into running it
this is not computer security
it's social engineering
What?Quote:

Run it, it's great

As Ynot said, it's a trojan horse, not a virus. Anyone can use a bit of social engineering to get people to run a destructive program on any operating system. I'll bet if you create a destructive executable (let's say a Platypus application bundle wrapped around a shell script) and replace its Finder icon with the Preview icon, the vast majority of Mac OS X users would double-click it, thinking it to be an image file that opens in Preview. You could archive it with tar to preserve the necessary metadata. An OS is only as secure as its users. What bothers me is that the OP sounded excited that 20,000 people just fscked up their computers...
Yeah, I'll admit it did make me a little excited on the inside :P
But yeah, if it's just a normal thing, then why make some news articles about it?
Trojans aren't considered viruses.
Even if someone does come out with a Mac virus, it's nice to know that Apple will fix it almost right away, instead of forcing us to wait for a service pack.
Holy batman, I better call shit!
Good thing I didn't try to go downloading illegal stuff...*cough*...Anyone know how to scan for trojan horses?
does anti virus software pick up trojan horses and worms? even though by definition they arent viruses
I don't think there are antivirus programs for Macs... if there are then people are getting really ripped off. I can write a Mac anti-virus program in ten seconds.
#include <stdio>
int main(){
std::cout<<"You are using a Mac, your computer is virus free.";
}
:D
Why did 20,000 people feel the urge to download an illegal copy of iWork 09 anyway? It's only 80 bucks and it's better than the $400 microsoft equivalent.
Oh, cool! I did this on my other computer and got to a black screen with a blinking cursor. Is it a text adventure or something? How do I start?? =DQuote:

Some people are ideologically opposed to [paying for] proprietary software (see here for example). Granted, they probably wouldn't be using Mac OS X due to issues of freedom, but a lot of people won't pay for a non-hard copy of software. Also, note that the home and student edition (the one people actually use) of MS Office for Mac OS X is about $115, not $400 (info gathered from microsoft's web site). Note further that OpenOffice.org is just about as full-featured as MS Office and iWorks, and it has the advantage of not restricting your freedoms and has the convenient price of $0. Note further still that word processors have been virtually obsolete for quite some time thanks to typesetting software like LaTeX, graphical document processors like LyX, and desktop publishing software like Scribus.Quote:

Your code isn't right either. In C, you are required to include (int argc, char ** argv) in main, it's not assumed like it is in C++ :tongue:
You're wrong about that. K&R says it's optional, and gcc with -strict and -pedantic doesn't issue any warnings. :P
oh what game?!Quote:

It mimics (worryingly closely) a biological virus
unable to function independently without invading a "host" program
The term "virus" has been incorrectly used (by non-tech people) to refer to any harmful program
this is wrong
Mac OS, Linux (and other *nixes) are, for all intents and purposes, immune to viruses
their security model prevents the copying of the viral code into other memory-resident programs
Viruses are a Windows-only problem
As for other programs....
as I said

Repositories are software stores, provided by your particular Linux distribution - your distro will vet all software in their repos, and you can rest assured that no harmful programs are present
Having the actual source code for programs (while not really for the average person) allows you to actually view what a program does.
If you're concerned about using a program (for some sensitive purpose - financial transactions, or whatever) you would employ a programmer to vet the program, and give his opinion on it's suitability
As I keep saying, anyone can write a program to do destructive things
it's really quite easy.....
but software vetted by either your distro, or some other 3rd party severley reduces the chances of accidentally running a bad program
(this is the beauty of open source software - anything bad is right there, in the code, for all to see - you can't hide bad things in open source software)
hey, i know that a trojan horse is different from a virus, and i know why, but i thought that a virus and a trojan horse was a program, but ynot is saying a virus isnt a program (even though his description of it would empley that it is a program), but dsr is saying that it is a program, so im pretty dam confused. in my own opinion, i would say that a virus would have to be a program, because what else could it be, and it would need something for it to know to replicate itself etc.
