IE8 was released to much fanfare recently ( Dean Hachamovitch at the Las Vegas MIX 09 conference ), but it hasn’t taken long for someone to find the first vulnerability. Nils, a hacker from Germany, banged the browser by using a previously unknown vulnerability in the browser, during the annual PWN2OWN contest held at the CanSecWest security conference. He won a $5000 and a Sony Vaio laptop for his efforts.
Moral? Don’t jump on the bleeding edge when it comes to Microsoft software.
On a final note, a MacBook was hacked in less than 10 seconds!!!
