In SR5 there was a red box labeled Uses of Snoop with the following text:
SR5 p. 242 Uses of Snoop
Snooping is often used for more than just eavesdropping. If your target makes a commcall, you can note the person they called and try to find them online with a Matrix Perception action; if they’re within 100 meters, you spot them right away (if they’re not running silent; if they are, then it’s back to the Matrix Perception Test).
Translated to SR6 and the case where you have a drone that is is operating remotely under autopilot and the rigger is not networked to it....
...would you say it is possible to Snoop all matrix traffic sent to and from the drone (after first gaining Admin access to it). And once the rigger send new instructions to the drone you take a Matrix Perception test to spot the rigger's PA (and once you infiltrated his PAN with Admin access you use Trace Icon to get his physical location)?
