Did you find any other reference to a Mac and that file?
EDITED:
Well, it's not really "hidden", it's simply in a folder regular users are supposed to tinker with. Path: BootDrive/System/Library/Image Capture/Devices/
I suspect you will find these files on every recent Mac OS. I have it on my iMac, the mini and my wife's MBP. If you want to remove it, don't be surprised if it gets re-installed at the next OS update. I'll leave it alone as I routinely use Image Capture.
