Doesn't that require the router to cooperate? As in, this is something that was developed to be used on purpose, but it's not very reliable on a random network you don't own.
You can see a lot of timing info from network sniffing even if you can't read it of course.
- rl3 3y ago>You can see a lot of timing info from network sniffing even if you can't read it of course. That was my primary assumption. Worst case, modern phones can act as hotspots—so if your phone is owned but stuffed in a drawer, it could theoretically sense beyond that and perhaps read your lips from another room. I'm guessing any stereotypical white vans worth their salt would provide fake devices for your phone to connect to in that case. On the baseband side, perhaps Stingray setups have the potential to be more useful than commonly imagined.
