Google Desktop Search (GSD)
Google Desktop is a utility that indexes the contents of a hard drive to provide quick search access to the user. Files indexed include email, office documents, chat logs, music, and web activity. It is possible to find deleted files within the contents of the index created by GSD. The main file of interest is “dbeam”, but the file structure is not easily parsed by current forensic tools. It is a text based file and therefore it is possible to conduct keyword searches looking for items of interest. The best workaround is to boot the forensic image in a VM or copy the files over to a clean GSD install as described by Hans Heins in the first research link.
