The WD World Book II is a network attached storage device meant for a typical home or professional user. It varies in storage capacity. At the time of writing the sizes vary between 250GB and 2TB. The device itself is the size of an external USB hard-drive, the larger capacities being wider than the base end models. Inside there is a controller board connected to one or two 3.5 inch hard drives. The Controller is running an ARM processor on 32 mb of ram.
The group at mybookworld.wikidot.com collected some scripts to trick the upgrade feature on the drives web interface to run arbitrary commands as root.
Out of the box, the underlying OS is not available. The goal of this project is to enable the ssh server and/or telnet.
