Both researchers who won $60,000 prizes at the March event -- Sergey Glazunov and someone identified only as "PinkiePie" -- also took home the Pwnie Award last month in the "Best Client-Side Bug" category for their Chrome work.
Another hacking contest will take place several weeks before Pwnium 2.
HP's TippingPoint will run a mobile-only version of its annual Pwn2Own in Amsterdam Sept. 19-20 at the EUSecWest security conference, where hackers will face off against Apple, Nokia, RIM and Samsung smartphones.
TippingPoint's Zero Day Initiative bug-buying program will host the event, with help from sponsors AT&T and RIM, the struggling maker of the BlackBerry. Prizes total $200,000, a record for Pwn2Own, with the top-dollar award of $100,000 going to the first researcher who demonstrates a hack of cellular baseband, the silicon inside mobile phones that connects them to carrier networks.
Other rewards will be handed out to the first to hack NFC (near field communication), the communications protocol being promoted for mobile payments, and SMS (short message service), the text-messaging service.
More information about the September Pwn2Own challenge can be found on TippingPoint's website.
