alt Hacker NewsAre you sure whatever you have configured in the MDM profile or one of these apps like Charles Proxy is not the source of the traffic?
Are you using a simple config profile on iOS to redirect DNS and if so how are you generating it ? Full MDM or what are you adding to the profile ?
Traffic was monitored on a physical ethernet cable via USB ethernet adapter to iOS device.
Charles Proxy was only used to time-associate manual application launch with attempts to reach destination hostnames and ports, to allowlist those on the separate physical router. If there was an open question about an app being a potential source of unexpected packets, the app was offloaded (data stayed on device, but app cannot be started).
MDM was not used to redirect DNS, only toggling features off in Apple Configurator.
