Protobufs were introduced in iOS 13.
So this is the first time you're hearing this term.
Protobuf stands for protocol buffer.
It's created by Google, and it's a way
to store information inside of other files.
So here we see GeoHistory.mapsdata
on the left.
We see group.comm.apple.Maps.plist
on the right.
Both of them have Protobufs in it.
Your clue that you're looking at a Protobuf, if you're
in Physical Analyzer, are all of these arrows.
So you really have to dig in and see this information.
Inspector, also a Cellebrite tool--
these are the Mac tools.
You would think that they would support Protobuf.
S Look at how the data may look if you
don't have a Protobuf viewer.
So you want to make sure that you're
able to see these Protobuf files.
