French security company Vupen says it’s figured out how to hack Google’s Chrome browser. Chrome has escaped unscathed in the last three Pwn2Own hacking contests. The exploit bypasses the browser’s built-in “sandbox” but also evades Windows 7’s anti-exploit technologies. Chrome’s sandbox technology is designed to isolate Chrome from the rest of the machine to make it very difficult for a hacker to hack the browser. Google has offered a $20,000 prize to the first researcher who hacked the browser and its sandbox.”]
