Trailrunner7 writes with this excerpt: "Building on the success of the last couple of years, Google plans to offer more than $2.7 million in potential rewards in the next iteration of its Pwnium hacking competition at this year's CanSecWest conference in Vancouver. The company has run the contest in parallel with the older Pwn2Own competition at the conference, with somewhat different rules, and this year plans to allow researchers to go after Chrome OS running on both ARM- and Intel-based Chromebooks. Pwnium began as Google's answer to Pwn2Own, the well-known hacking contest that has attracted some of the top researchers in the industry over the course of the last few years, including Dino Dai Zovi, Charlie Miller, Chaouki Bekrar and the Vupen team and many others. ... But the money that Google is putting up for new compromises of Chrome OS is far beyond what's available at Pwn2Own or any of the other major contests and has attracted a small, but elite, group of contestants in past years. The company is promising rewards of as much as $150,000 plus some bonuses, paid at Google's discretion, for especially innovative or serious exploits."
