Hackers exploited the 3 major browsers on day one of Pwn2Own.  As expected,  IE8, FireFox and Safari were all penetrated within minutes of the competition starting.

Most impressively, Peter Vreugdenhil, was able to exploit a vulnerability in IE8 on Windows 7 allowing him to bypass  the operating systems DEP (Data Execution System) security mechinism designed to stop this sort of attack.  Vreugdenhil, a first time Pwn2Own participant, earned a $10,000 prize for his efforts.

The only browser left standing after day one was Google Chrome.

Seems a few things were missed back in the 2.8.1 security release, but 2.8.3 is supposed to fix all that.

Unfortunately, I missed some places when fixing the privilege escalation issues for 2.8.1.  Luckily, the entire WordPress community has our backs.
