Microsoft, not Adobe, is responsible for patching Flash Player in Windows 8 because the former has mimicked Google's Chrome by building the software into IE10.

While Windows 8 has not officially launched -- the new OS goes on sale Oct. 26 -- developers, IT professionals and many enterprises have had access to Windows 8 since mid-August.

Andrew Storms, director of security operations with nCircle Security, saw Google's hand in the unexpected Flash update.

"This idea that Adobe would coordinate with Microsoft makes me ask why couldn't they have waited until tomorrow?" Storms asked, noting that Oct. 9 is Microsoft's already-scheduled Patch Tuesday. "There are no exploits in the wild, according to Adobe. But then I got wind of this whole Pwnium thing, so the stars pretty much align."

Under Storms' theory, Adobe felt obliged to ship the Flash update today because -- dubbed "Pwnium 2" -- in Kuala Lumpur, Malaysia, on Wednesday.
