Billboard Hacking

Hi All,

I was wondering if someone could point me in the direction of where to get some up to date material on Billboard hacking and how to find the admin pages for these etc.
Or is it mostly physical attacks that people are doing on these?

I can see some material from Defcon 16. so quite old and most of the links I’m looking at seem to talk about the Defcon talk.

Anybody with theoretical experience of this or know of someone who may have done this sort of thing previously, jsut interested to know how this is done.

k thnx in advance.
