Now that I have a chance to look at the SR5 book, there is an option to Jam Signals (pg 240), and Reboot Device. (pg.242). You could also Control Device and lock out the user,and/or put it into 'airplane mode', theoretically.
- Jam Signals just does the same thing as a jammer (shuts off wireless bonuses and introduces a noise penalty), per the rules clarification from Aaron. It doesn't stop people from communicating (yes, I think it's stupid).
- Reboot Device cannot be performed if someone has formed a persona on the device, which is going to be about 95% of the time given how ubiquitous AR is. You form a persona whenever in AR or VR.
- Control Device might allow that... maybe. An owner always has more MARKs on a device than a hacker, it's questionable whether they can lock out the owner or silently put something in "airplane mode" without the owner being alerted in AR. In which case they just manually turn it back on...
