Microsoft hasn't prepared any patches to its Internet Explorer 8 browser before the Pwn2Own browser exploit challenge slated for March 9 to March 11 at the CanSecWest security conference in Vancouver, B.C, reports PC Magazine.
Mozilla and Google have updated their browsers in the past week, with Mozilla fixing 10 flaws in Firefox and Google fixing nearly 20 vulnerabilities in its latest version of Chrome.
Contestants in the challenge compete to see if they can exploit software, including web browsers. The best hackers can win $15,000 or more in prizes.
Hackers this year will try to exploit weaknesses Microsoft's IE8, Apple's Safari, Mozilla's Firefox, and Google Chrome. They also would focus on the security of mobile phones, including: Dell Venue Pro, iPhone 4, Blackberry Torch 9800, and Android Nexus S.
Microsoft is getting ready to introduce Internet Explorer 9 in the coming weeks. And Microsoft recently started encouraging people to stop using Internet Explore 6.
