It should be mentioned that this work was mostly speculation, like the speaker said.<p>Most of the attacks shown are not 'advanced' by any means. Like the speaker explained; <i>'anyone can buy a GPS jammer for a few bucks online'</i>. The research they did indeed confirmed GPS is the weakspot. However, such geofence systems are a step-up from any equipment lacking this ability. Its not so much about rendering these systems completely unusable outside of their intended purpose, but more about slowing down their use. The later will have a much better chance of accomplishing this goal.<p>Assuming the claims made in this research are true, then its more likely the CIA wants to limit the use of <i>US</i> supplied weapons systems, not stop a war. And the CIA has quite the history there.<p>Also, the situations in which such weapons systems are deployed do not exactly resemble the lab-like circumstances (like faraday cage, EE-tooling et.) necessary for these attacks.
