Inside one file lies a database row containing a users “host_id”, which is used to authenticate each individual user. Newton’s concept, tested on a Windows machine, uses Dropbox’s own configuration files configuration data, file/directory listings, hashes which are stored in numerous SQLite database files located in %APPDATA%\Dropbox.
#DROPBOX SECURITY INSTALL#
With Dropbox users needing to install the client on each computer they wish to synchronise, user credentials are locally stored in data files (sometimes) across numerous workstations. The “attack” is achieved by obtaining the Dropbox ID of a user or by copying files that are associated with a Dropbox install on a user’s computer. Recognising that other users had reached the same conclusion ( here and here), Newton didn’t think that “people the significance of the way Dropbox authentication,” so he published his findings from an “authentication standpoint and the significant security implications that the present implementation of Dropbox brings to the table”.
