(The impatient can just scroll through to 04:45 to see the news manipulation in action)
With hardware hidden in a small, innocuous wall plug, we demonstrate wireless alteration of news headline:
"Beijing seeks to ease US fears"
"Beijing to invest in US Army"
.. on an Acer Netbook, Macbook Pro and Nokia N900 smartphone.
This is done with the following trivial packet header and payload filter:
if (ip.proto == TCP && tcp.src == 80)
if (search(DATA.data, "Beijing\ seeks\ to\ ease\ US\ fears"))
replace("Beijing\ seeks\ to\ ease\ US\ fears", "Beijing\ to\ invest\ in\ US\ army\ ");
This could just as equally be performed in any cafe, school, library or airport with a remote user logging in and manipulating news content read by wireless network users. No connection with - or modification of - any software on the laptops, tablets, phones affected is required.
The skeptical should view in HD video to get a closer look at those wonderfully informative terminals!
