strange: random google-XXX.dmg mounts and umounts on OSX

Question

I just noticed via HardwareGrowl, that a .dmg image file mounted and unmounted all by itself. It was called google-XXX.dmg (where XXX represents a number i did not note down that fast.

I am running Mac OSX 10.6.4 on a MacBook Pro. No Google product was running at the time of the incident. Only Google product installed is GoogleAppEngineLauncher. The .dmg file was gone after the unmount. I was not fast enough to detect the process, which initiated the mount.

My Questions: - Is this the known behaviour of some google update mechanism? - If so how to stop this? - I was not able to find an entry in the logs, do you have any suggestion where to look for traces of this event?

There are 2 similar stories from Chrome users i could find (i don't have Chrome installed): Chrome installation volume mounts randomly on Mac OS X http://www.google.com/support/forum/p/Chrome/thread?tid=3b32d0d9219a1df0&hl=en

Solution

Perhaps it's Google's autoupdate software updating... itself. Try monitoring network connections. I use Little Snitch for this.

I saw this yesterday as well--I assumed at the time that it was Google Chrome autoupdating.

Though, there -was- a Chrome update just yesterday.
