Hacker: Windows More Secure Than Mac OS X

by - source: Tom's Hardware US

Hackers just like the PC more.

Regardless of which side you're on (though as a true computing enthusiast, you shouldn't be taking sides), you've heard the arguments back and forth on the which operating system is truly safer – Mac OS X or Windows.

It is of the opinion of Charlie Miller, a well known Mac security guru, that even Snow Leopard, the latest version of Mac OS X, isn't as safe as Windows.

One key point is that Snow Leopard still doesn't have ASLR, or address space layout randomization, which randomly arranges the position of key data making it harder for hackers to target for exploits.

Miller said to TechWorld that Apple didn't change the ASLR from 10.5 to 10.6: "Apple didn't change anything. It's the exact same ASLR as in Leopard, which means it's not very good."

Apple didn’t completely missed the chance to tighten up security in Snow Leopard though, as the new QuickTime solves a lot of the issues that Mac OS X had before.

"Apple rewrote a bunch of QuickTime," said Miller, "which was really smart, since it's been the source of lots of bugs in the past."

One thing that Snow Leopard did adapt, which Windows has had since XP SP2, is DEP (data execution prevention). With DEP, buffer overflow attacks are much harder to execute.

Despite Miller's opinion that Windows is the more secure OS, the large install based of Microsoft-based systems make them a much more attractive target for hackers. Still, Miller would like to see security on all platforms.

"Snow Leopard's more secure than Leopard, but it's not as secure as Vista or Windows 7," he said. "When Apple has both [in place], that's when I'll stop complaining about Apple's security."

Keep in mind it was an apple developer saying this himself, sounds like this guy could be the anti-christ for those PC vs. Mac commercials.

So I bet this isn't going to make it amongst the bias PC vs. Mac ads

Note: this is the same guy that won at Own2Pwn last year. So Im pretty sure he knows what hes talking about.

But Mac users live in a little false reality bubble with twirling rainbows and lies about being impervious to maleware.

dont worry, when apple gets more shares, they will feel the wrath of the hackers

Plus by the time Apple is done spinning this the Fanboys will be claiming that this is all a scheme devised by MS.

Amen! lol

I'm always tired of Mac users saying "Oh, but there is less malware for Macs out there!" My response to that is "Hackers just feel sorry for Mac users and decide not to make their lives even more miserable than they already are with using a Mac." ;) Now I can say that Windows is more secure! :D

(P.S. I am not one of those people that have never used a Mac and say that I don't like it, I have been using one extensively over the summer and have found out how much time I have saved by using a Windows computer all of my life ;))

I work for a small creative agency where I am the sole Windows user out of simple preference. I do not nor have I ever had malice or negative thoughts about Apple products. I have owned both...and yet I am constantly attacked about having an inferior device because it isn't Apple. I don't like being forced into a corner and having to defend myself and it really pisses me off. Both have strengths and weaknesses and as the author of the article pointed out, the true computer enthusiast does not care...and I really don't.

Apple needs to add the FreeBSD Jails Subsystem:

along with OpenBSD PF:

DEP is old news, has been in OpenBSD for a while W^X:

As for ASLR, its not that big of an issue. The attacks that ASLR protects on Windows don't effect Mac OS X.

It's not that difficult to understand if you really think about it. What does every computer system that has anything important on it run? Some version of Windows. You don't see the CIA's servers running Mac OS. Just using that as a broad example. Do you see your local bank running Mac OS? Police department? and so on and so on. The reason why Mac OS is so "secure" is because it doesn't run on any computer system people want to see/steal data from. If the Pentagon switched to Mac OS...how lon do you think it would take before "hackers" had penetrated it? I use "" because there are very few true hackers left out there.

There is nothing new in this article. Any smart computer user will know that there is no such thing is

ChaosGS :
Get an edit button on here, stupid toms. While your working on the edit button, get some non biased authors or some authors with a brain. Jane is the only decent author on here. Marcus has always been a biased retarded individual, serious stop writing topics, and just spell check its about all your good for.



Ummmm...take a look at that last sentence again and see if you can find anything in his article that is as poorly written... :P

I wonder why people think ASLR is unimportant? To me it seems like just one more layer of security.... I like extra layers when it comes to security and if it does not impose any significant performance loss then why not? To argue against extra security is crazy on any platform.

"Apple didn’t completely missed the chance to tighten up security in Snow Leopard though"

oh wow , every one here knows how shitty my typos, but damn , when i catch a gramatical error , you know you need better editoral skills LOL that line should read:



"Apple didn’t completely miss the chance to tighten up security in Snow Leopard though"

hehe, they say "you don't get viruses on a mac, you get lots of viruses on a PC, because they are unsecure."

Notice how it doesn't say macs are secure, it doesn't even say that macs are more secure than PCs. but that is exactly what people would would think its saying.

The only department of apple that is truly innovating and pushing boundaries is their marketing department.

missed should read miss

based should read base

Is grammar out the window at Tom's? The editorial staff is slacking off or something. I love Tom's I've been reading for eight years, but seriously folks.

I'm pretty sure that the programmers at Apple, just like their Mac user cronies, think their stuff is just invincible as it is. I'm sure once the Mac user base grows big enough to be a suitable target reality will enlighten them.

(Generally speaking) we already knew this. Unfortunately, the general public does not know. And the "Get a Mac" ads don't help in informing the public of the truth (that Windows is more secure, but tastier to hackers because of the large install base and users who don't know what they are doing).
