Though Pwnium may (quietly) reveal exploits in Chrome, Google will conveniently not be featured in sensationalist headlines about Chrome being hacked more quickly or often than other browsers at Pwn2Own.
Are you familiar with the Chrome's history at Pwn2Own?
Its success at avoiding attacks has been a great marketing tool for Google.
Even with this Pwnium exploit don't make the mistake of thinking Chrome is an insecure browser. By any measure it is the safest (graphical, full featured) browser around by a long way.
So for people as confused about this as I was, there are two similar but distinct contests at CanSecWest right now. Google Chrome is a target in both of them, and it has fallen in both of them.
This tweet refers to Pwn2Own, which is the one sponsored by ZDI, and which VUPEN apparently won (without having to share their exploit). The other, pwnium, is the Google-sponsored contest.
