Hacks for iRex iLiad and Sony Reader round-up

Aside the obvious E Ink technology, what makes the iLiad and the Reader similar is the fact that both devices run on Linux. While we are still waiting for iRex and Sony to release SDKs, clever MobileReaders have found their own ways to gain shell access to both devices.

Here is a current round-up of all hacking attempts:

Sony Reader

iRex iLiad

I guess iRex and Sony will both start working very hard at fixing these "holes" tomorrow...:-)

Maybe it's time the both (but especially iRex) see the light and offer a full-fledged SDK because otherwise the hacking will continue and possibly reveal a lot more than they ever intenede the public to see...

At least the pressure is getting higher to make them actually do something. Other than empty promises.

All these hacks bring up a question for me...

Has anyone ever tried to use the Pepperpad 3 as an ebook reader?

That makes the problems more obvious to the security community at large, and helps increase that pressure to get things right.

The only security-involved hack is the existence of a open Xserver, and even this does not qualify as a security problem if a way to write to the disk is not found, at this moment it is only a partial privacy problem. Moreover, in standard mode, the Xserver display is not showing any text while it is opened.

As for the other hacks, you can not tell that accesing a device from its main console is a security hole, can you?

This could be a serious exploit - in my office, all computers are on the same LAN. Easy to popup a dialog on the manager's Iliad asking for his master username and password, then log the response.

An open X server is always a security problem. It's an oversight in configuration, and where there is one mistake, there are probably more. The severity of it may be high or low -- and also tends to alter over time, and depending on who is affected by it. To the bog-standard iLiad it is probably fairly small right now, but is that true also for that flight-chart reading iLiad, or any other special iLiads in the works?

My concern was, however, more with the Sony Reader - it occurred to me that the ability to read and write files via USB just might make it easier to get round DRM protection.

That doesn't matter since it's much simpler to hack the PC software.

Not something we might necessarily want to do. Right?
