Several prizes went unclaimed Wednesday, including the two $70,000 awards for Adobe's Flash Player and Adobe Reader on Windows 7, and the $65,000 check for Safari on OS X Mountain Lion. Flash and Reader are slated to be attacked today.
Google's own contest, Pwnium 3, kicks off Thursday at CanSecWest when Chrome OS -- the search giant's browser-based operating system -- will be targeted by researchers. Pwnium 3 is notable for the $3.14 million Google has set aside for potential awards, and for the individual prizes of as much as $150,000 for each successful exploit.
This is Pwn2Own's eighth year, but the total prize pool of more than a half million dollars is a record for the contest.
More information about Pwn2Own can be found on TippingPoint's blog.
