I read that Mac OS X with Safari was the first to be beaten (at least of the computer type systems...iPhone may have been actually the first though).
A little more info at this link. Not sure why they aren’t including more detail, nerds eat this stuff up...
These speed competitions are exciting, and make a lot of splash, but aren't all that useful for system comparisons. Any system can be compromised, given physical access to the machine. Every system.
We all realize that in a speed competition like this, it's really about how prepared the hacker is, how quickly their script runs, etc. The simplicity or complexity of the exploit has little to do with it, since these are all scripted and practiced ahead of time. The time it takes to execute actually has very little relevance to the relative security of the system -- ANY compromise is a compromise. And every system can be compromised if you have physical access to it.
Almost every existing real virus is based on OLD exploits, in systems that aren't patched, or whose operators allow them to be compromised. Very few real viruses are based on recently discovered exploits, and those that are, are extremely newsworthy.
Speaking as a life-long (58, since 1970) computer professional with decades of experience in ALL these systems, a more meaningful speed/time-releated measurement would be this:
Starting at the date/time of the competition, how long will it take for the successful exploit to be realized in a self-replicating virus?Right? Otherwise, who gives a damn? Seriously. We all know and agree that every system has flaws and can be compromised given physical access to the machine. What matters is whether it can be realized as a virus that can travel.
In that regard, Win7, OS-X, Linux, BSD, are all quite robust these days, and improving.
Anything less than a self-replicating virus is just wanking in the laboratory, and some marketing-driven contrived competitions based on having physical access to the box. Exciting? Sure. Meaningful? Not so much. Let's not confuse this sideshow with reality, which is tens of millions of computers in the wild, not one computer in a lab.
That means absolutely nothing... As I understand the rules, the time slots are drawn by lots except that last year's winner, if he is competing, always gets the first shot. Charlie Miller has been the winner for the last four years. That means that since Charlie Miler has the first 15 minute slot to make the first attempt. The rest have to wait their turn. Ergo, since he was up first, and he made his attempt at OSX, it got beaten first.
