DropBox attacked by spammers?

Has anyone recently seen odd movie files showing up in their DropBox folder?

I just noticed a Growl notification that indicated the file "CandidCamera.wmv" was removed from my DropBox folder, yet I never initiated any action.

Since WMV movie files are a standard attack vector for many computers, I'm wondering if spammers have somehow hit Dropbox and Dropbox took action to remove those files.

Anyone else seeing this behavior? Now I am getting concerned about my use of DropBox.
