I can confirm stated concerns, i've been dealing with this for over a year now.
I believe all our devices (iphones, ipad, windows pc's, synology nas, network printers, and possibly router) were compromised at some point. (Or still are) Suspected attacker briefly had physical access to my iphone and laptop at some point, and has been actively hacking our wifi network at night.
Iphone / apple account silently being enrolled in beta / developer updates, "MDM-enrollment is mandatory: YES"
Settings changing on its own, iphones randomly asking for password. Iphone running on 1% battery for many hours straight. Static noices in calls, calls not coming through, camara and microphone indicator lighting up for no reason.
Even after wiping and reinstalling IOS in DFU mode:
setting up as new device shows message "This device is allready partially setup." Selecting "erase and start over" just creates a loop.
I've been combing out iphone backups with iMazing, and keep finding more and more indicators of the devices being managed, supervised, enrolled in MDM environments and what not where they absolutely should not be.
Oh, i've contacted Apple Support a few times, after you're finally get put trough to level2 support you might get some confirmations or info on these processes but you need to be very specific. For instance, i've been confirmed an MDM enrollment or installed configuration profile or literally any other setting can simply be hidden from the user interface when enrolled in mdm. Also i've found plists listing App store overlay, SuppressShowingInSettings, systemcustomization, and many more.
This also explains why my UI always looks a bit different after another DFU wipe and restore.
However, they did tell me I shouldnt be able to use my iPhone, since it should have an activation lock on it. Go figure.
When triggering a sysdiagnose on iphone, it creates a log in "Privacy and security" / Analytics and improvements / Analytics.
Share the sysdiagnose file to folder so you can open individual .plist files locally on your iphone.
I've been searching through many files, logs, plists and jsons.
Giving ChatGPT extensive instructions to analyse these files and search for indicators of mdm, proxied traffic, remote managed settings, syncing of devices, etc.
I am slowly building my findings, but this stalkerware is well hidden and deeply integrated in or abusing legitemate ios processes making it difficult to prove and trace back to the culprit for now.
We need a community to gather and combine our research, and a few experts willing to investigate this further.
