 This JSON file is created by mvt-ios' `Netusage` module. The module extracts records from a SQLite database located */private/var/networkd/netusage.sqlite*, which contains a history of data usage by processes running on the system. Besides the network statistics, these records are particularly important because they might show traces of malicious process executions and the relevant timeframe. In particular, processes which do not have a valid bundle ID might require particular attention.
