At the time of writing this, there weren’t many tools that supported parsing Protobufs. With the introduction of iOS 13, we realized that the Apple Maps data was being stored in protocol buffers aka Protobufs. Yes, this isn’t a recent discovery, yet many tools struggle with the parsing of this type of data. While Cellebrite parses the two primary Protobufs shown above, there are so many left untouched. We recommend using protoc to parse the unsupported ones.
