The Null Device
Last browser standing
Recently, the annual Pwn2Own contest took place; in it, participants try to take over a computer by exploiting security holes in a web browser, and capture the flag (in this case, a file on the computer's hard drive). This year, all the browsers but one fell
; Firefox 3.6.2 (though it's not clear whether NoScript
would have mitigated this), IE8 and Safari all fell; one of the hackers even pwned an (un-jailbroken) iPhone and made off with the SMS database. The one browser that remained standing: Google Chrome
, not because it's bug-free, but because the sandbox mechanism makes exploiting bugs impractical:
"There are bugs in Chrome but they're very hard to exploit. I have a Chrome vulnerability right now but I don't know how to exploit it. It's really hard. They've got that sandbox model that's hard to get out of. With Chrome, it's a combination of things - you can't execute on the heap, the OS protections in Windows and the Sandbox."
