Agreed, but I would not actually be surprised if they did not learn anything yet. The embedded hardware world is not quite as well connected in that sense as the web start-up scene. It could take a few days before the circle of the people that know about this and the circle of the people involved in that company intersect.
Which makes me wonder, is network traffic profiling common. Like, will the local network admins be getting alerts for traffic spikes on port 23 (SNORT and the like do this sort of intrusion detection I think?)?
