If you’re going to announce that your new browser is the safest on the market, you’d best be damned sure you’re right. It seems Microsoft releasing Internet Explorer 8 out of open beta yesterday was a red flag to a bull (or a challenge to a hacker), because within 24 hours a new exploit has been found in the browser.

The feat occurred at the annual CanSecWest security conference, which hosted its PWN2OWN hacking contest, where the exploit was found. A German hacker going by the name of Nils found it and claims a prize of $5000 in cash and a Sony Vaio laptop as a prize.

It’s only fair to mention that the same hacker managed to claim an additional $10,000 for successfully hacking Safari and Firefox. There’s still two days left for more browsers to succumb to the hacker’s codey wiles – perhaps Chrome and Opera will let their guard slip as well.
