Google promised it would reveal more information about Pinkie Pie's exploit once other WebKit-built browsers -- Apple's Safari also relies on the open-source WebKit engine -- have been updated.
Earlier this year, about the March Pwnium hacks by Pinkie Pie and Sergey Glazunov until late May.
As he did last March, Jason Kersey, a Chrome program manager, called Pinkie Pie's hack a "beautiful work of art."
Google today patched the Chrome vulnerabilities Pinkie Pie used during the contest, and boasted of its turn-around time.
"We started analyzing the exploit as soon as it was submitted, and in fewer than 10 hours after Pwnium 2 concluded we were updating users with a freshly-patched version of Chrome," said Evans today.
