Personal Apple ID appears managed by unauthorized MDM

Dear All,

**Only respectful, positive, intelligent contributions are requested. Anything else, abstain**

I have been investigating a compromise of my apple ecosystem via a hidden malicious MDM. Regular checks (settings/profiles etc....) won't bring up much information, but when going into the library folders, the existence of plist configurations file (managed preferences), browsers updaters being managed under Enterprise/companion attribute, user configuration profiles created and not removable, records of Apple Configurator in the unified system logs reveal the hidden nature of this unauthorized management.

Recently I decided to try something and entered my regular appleID in the Device Management pane (no profiles are being shown) and to my surprise, the appleID was accepted, the remote management servers were interrogated and a notification popped up on the screen "Your managed Apple account is already signed..." (see attached).

I thought only work/school type emails could be "managed". Logs from Console also show the same activity

So I then decided to try with the iCloud version of my appleID and here's the notification that I received

As I said before, my apple ecosystem is compromised by someone with previous local access via malicious management installation. I have already tried everything imaginable (factory reset, complete change of accounts, clean OS reinstall and in the case of the screenshots shown), bought brand new MacBooks with appleIDs created from scratch.

Please if anyone has a constructive comment, advice, analysis, I am all ear. Only respectful, positive, intelligent contributions are requested.

Anything else, abstain!

Thank You!
