I've not had anything stolen- even with that, our post office put in cluster boxes a few years back with parcel lockers, so anything coming USPS that isn't huge typically goes in there. The only package I would have worried about was my Xbox One, which I ordered during a Prime Day sale & Amazon opted not to box it. At all. Just stuck a shipping label on the retail box & sent it. It's also the only time the UPS driver ever knocked, and I appreciate that man greatly for putting my console directly into my hands.
I sincerely doubt anyone is hacking your wifi to monitor your shipping information to stalk your packages. That's a lot of effort for very little return (it's not like much of what people buy actually has resale value once it's away from a store.) I imagine your typical package thief is doing the far simpler task of- just knowing when the delivery trucks are out. Why go through the effort of tracking a group's shopping habits in the hope they'll buy something AND ship it somewhere unsecured, when you can just follow the amazon truck around & wait for it to leave something on someone's porch?
Remember, most theft is based on opportunity- you're not likely to be targeted directly unless you're flaunting your wealth pretty fiercely.
