"VUPEN won a $15,000 cash prize and an Apple MacBook Air 13″ running Mac OS X Snow Leopard" ... and Calcuator.app, whether he wanted running it or not.

I'm not surprised, this is what the third year in a row now? I hope Apple pays attention to the things Google is doing with Chrome. If I'm not mistaken, Lion will be shipping with WebKit2 and sand-boxing.

I've tried Chrome, but I just always go back strangely to Safari it just feels right at home.

Stormbringer2• 15 years ago

Isn't the surprise rather that it is not the guy who knocked it over straight away three years running?

This is really embarrassing for OS X fans.

darren_3• 15 years ago

It's not surprising because he [Charlie Miller] was fourth or fifth in line.

Everyone who signs up for this has exploits already in the bag that they've been working on for weeks, it's not like it's hackers showing up and racing each other to discover exploits from scratch (which, incidentally, renders the whole "first to fall"/"browser X pwned in seconds" style of headline asinine)

alperakgun• 15 years ago

apparently apple does not spend time for securing their toys, they just polish.

trotsky8• 15 years ago

Five years in a row, as cansec west has run pwn2own for five years. OS X/Safari has also always been the first one to drop afaik, though this has at least as much to do with Apple kit being the most desirable as anything else.

tjogin• 15 years ago

It's not a race. The exploits are prepared far in advance, and whichever is hacked first is determined by the random order in which the challengers get to demonstrate their hacks.

magicofpi• 15 years ago

Apple is also apparently sharing an developer version of Lion with security researchers[1], so hopefully it'll be more secure by next year.

So you win a version of the most vulnerable software/hardware?

YooLi2• 15 years ago

Taking down the Mac gets you the best laptop and the most press. Simple.

It would be different if the other OS/browsers didn't go down too, but because the Mac is always first to go just means it's the most desirable target.

kenjackson2• 15 years ago

I think the $15,000 cash prize and PR with being first, regardless of OS/browser, plays larger than the delta between getting a high PC laptop and a MBP. And it's not like they don't already have Macs -- that's how they developed their OS X exploit.

UPDATE: It's actually a MacBook Air 13", not MBP. The other laptops are ASUS G73SW and Alienware M11x.

trotsky8• 15 years ago

Taking down chrome would definitely get you the most trade press by far. Just sayin'

latch2• 15 years ago

I can see how you associate it being the least secure with it being the most awesome. I don't see what could go wrong with your ability to take some legitimate and important criticism about something you like and turn it into something awesome about said thing.

Mac's always go down quickly in these contests. The people who make it happen often say that its considerably easier.

edit: Charlie Miller: "It's really simple. Safari on the Mac is easier to exploit. The things that Windows do to make it harder (for an exploit to work), Macs don't do. Hacking into Macs is so much easier." - http://www.zdnet.com/blog/security/questions-for-pwn2own-hac...

icarus_drowning• 15 years ago

The existence of the vulnerability itself is now obvious-- no one is arguing against it. (And thus, I don't think anyone's arguing that a fully-patched OS X system is fully impenetrable). But the fact that the winner gets to keep the hardware certainly has a lot to do with which target they choose to attack.

Did Safari fall first because it is the least secure, or because it is the hardware everyone wants to win? It really is difficult, if not impossible to tell.

Personally, I'm quite sure that the Windows machines are at this point far more secure, simply because Microsoft takes so much battering by being in the dominant position. But I wouldn't use this as evidence for it.

EDIT: Question about your quote-- later in that article, Miller suggests that there is no "randomization" in OS X, while this year's article says his exploit bypassed ASLR in OS X-- is this a new feature in OS X that wasn't present in 2009?

rbanffy• 15 years ago

> I can see how you associate it being the least secure with it being the most awesome

In fact he associated the fact of being the most awesome and generating the most media coverage with the fact it would be the first to fall, regardless of how secure or not the computer is.

tzs• 15 years ago

Wait...are you under the impression that the hacks are developed on the spot when the challenger steps up to the computer?

In fact, they are developed far in advance. The order the browsers fall is determined by the order the challengers get to demonstrate their hacks.

wisty• 15 years ago

That's simply not true. Macs are often said to be easier to take down.

However, a vulnerability on the Mac isn't worth as much (on the black-market) as a vulnerability on Windows. So people keep trying to break Windows. Even if you tried to sell a Mac vulnerability, the people who make botnets wouldn't be interested, as they can buy Windows vulnerabilities instead.

pwn2own is the only show in town where a Mac vulnerability is worth roughly the same as a Windows one.

statictype• 15 years ago

but because the Mac is always first to go just means it's the most desirable target

I suppose being the easiest target couldn't possibly be a reason, could it?

You're one of those people that cause others to label Mac users as zealots suffering from cognitive dissonance, aren't you?

trotsky8• 15 years ago

Amusing how paranoid the browser developers have become about CanSecWest:

Pwn2Own browser day: March 9th, 2011

  Safari 5.0.4 released March 9th
  Chrome 10.0.648.127 released March 8th
  Firefox 3.6.15 released March 4th
  Internet Explorer 8 didn't get a patch this cycle (too cool for school)

Mobile day: March 10th, 2011

  iOS 4.3 released March 9th
  Nexus S 2.3.3 released Feb 24th
  Not sure about WP7 & BB

jjcm• 15 years ago

To be fair, Chrome gets updated around every two weeks. That it happened to get pushed out the day before CanSecWest may just be a coincidence. Firefox tends to release a new version every month or so as well Though Mozilla did push 3.6.15 four days after 3.6.14, so it may very well play into your point.

trotsky8• 15 years ago

It's definitely a known tactic though, here is a tweet from the people who took down safari:

@VUPEN: Anti-pwn2own again: Apple fixed a record of 50 vuln. in Webkit (iTunes), and is preparing the update for Safari / Mac OS X... (1:43 AM Mar 3rd via web)

http://twitter.com/VUPEN/status/43245159776915456

And the trades agree:

Mozilla follows Google, patches Firefox as prep for Pwn2Own

etc.

FWIW, Safari 5.0.3 was used for the competition.

Besides, if most competitors arrive at the competition with carefully-researched exploits available to use, I'm not sure this sort of last-minute patching would make much difference, even if it was intentional.

trotsky8• 15 years ago

Apparently the last weeks code rule was a surprise, I don't think the vendors knew about it.

I'm not sure this sort of last-minute patching would make much difference

Even if the vulnerability is still there, screwing with the way the binary is built and linked could easily make it so they'd have to put it back in a debugger and retune the exploit.

darren_3• 15 years ago

Interestingly, according to http://www.computerworld.com/s/article/9214002/Safari_IE_hac... , the researchers who signed up to hit Chrome have either not shown up or decided to concentrate on Blackberry instead. Seems their sandbox holds up quite well.

adsr2• 15 years ago

I question the metric used in these contests. Reports always makes it sound like someone just walks up completely unprepared and hacks a machine.

”We had to do everything from scratch. We had to create a debugging tool, create the shellcode and create the ROP (return oriented programming) technique,”

Obviously there is a fair bit of preparation involved.

trotsky8• 15 years ago

They're all prepared in advance. I don't really understand what you mean about the reporting though, as you point out the discussion makes it clear none of this is off the cuff.

adsr2• 15 years ago

Yeah that is my point, then why is there a focus on who is first?

GHFigs• 15 years ago

Every year the press makes it sound like a race, or that being exploited first is somehow worse than being exploited later in the day. The fact is that time slots are assigned randomly: http://twitter.com/VUPEN/status/40078022325444608
