Extracting with ghidra misses quite a few files due to how they're split between multiple chunks. Must use https://github.com/keith/dyld-shared-cache-extractor on a mac

[acheong08]

Behavior on IOS does not match MacOS. Some URLs such as https://gsp64-ssl.ls.apple.com/hvr/v3/use do not show up in geoanalyticsd despite the data clearly signaling the source. Currently decompiling ipsw for reverse engineering. dyld shared cache on IOS appears much larger at ~4GB (vs ~1GB on MacOS)

[acheong08]

+[GEOAPPortal_captureTransitAppLaunchWithBundleIdentifier:source:destination:timestamp:additionalStates:providedDropRate:completionQueue:completionBlock:] in GeoAnalytics seems to match up with parts of https://gsp64-ssl.ls.apple.com/hvr/v3/use

It includes the bundle identifiers of apps you use while in transit (including current location, source, and destination)

[acheong08]

Need to track down geod.

Somehow it's sending off data such as where I spent my money. ARPC (Apple Remote Procedural Call) needs to be reverse engineered. It is not protobuf
