Googles Chrome Browser is still safe after a Pwn2Own contest where Google, and TippingPoint would give the successful team to exploit Google's browser first $20,000. Also On Wednesday, researchers successfully exploited Safari and Internet Explorer. A team from French security company Vupen took down Safari 5 running on a MacBook Air notebook in five seconds, and independent researcher Stephen Fewer used a trio of vulnerabilities to hack IE8 on Windows 7. Pwn2Own continues today and Friday, when Mozilla's Firefox and four smartphones running Apple's iOS, Google's Android, Microsoft's Windows 7 Phone and RIM's BlackBerry OS will be in researchers' crosshairs.
