Attackers can listen in on internet traffic for high-value targets a continent away, like shipping fleets and oil installations, using some basic home-television gear. Attackers would then examine the data to discover whether they ve found a TV feed or a terabyte of internet traffic.

The researchers used a software tool called EPS Pro to help people find satellite television channels.
