Apple's Safari web browser was the first to be cracked open by security specialists participating in the Pwn2Own conference, second to fall was Microsoft's Internet Explorer.
The Pwn2Own hacking contest, which is a part of the CanSecWest security conference in Vancouver, involves security researchers trying to break into popular web browsers.
Internet security firm Vupen was the first to break into Apple's Safari web browser, which was running on a secure version of the Mac OS X platform, The Inquirer reports.
The winning team received a £15,000 cash prize and a 13-inch MacBook for hacking into the browser. The researchers were able to hack into the browser despite Apple releasing a patch for it at the last minute.
Microsoft's Internet Explorer 8 web browser was hacked by Steven Fisher of the security firm Harmony, winning a laptop and $15,000 cash prize. Fisher said that it took him six weeks to find a way into the web browser with the protected mode on.
Meanwhile, security researchers have not been able to hack into Google's Chrome web browser. Google has offered an additional $20,000 to the person who hacks into the browser. A hacker would have to hack into the browser and steer clear of the sandbox using existing vulnerabilities in the Google Code.
However, Google has also offered prize money to the hacker who manages to escape the sandbox using non-Google code. The Chrome and Firefox browsers will be the target of hackers on the second day of the contest.
