In my case I'm coming off a fresh DFU restore done at the Apple Store on a new 2024 MBA M3.
The open ports are all in the 49152–65535 range which appear to be related to the Xsan Filesystem Access (thanks for the reference!)
I'm a regular consumer with no association to any corporate workplace. My sense is this machine is bound to a VPN that I cannot control or remove, and my web content and experience seems to be altered. For example, my Google search results are different when I search from other devices. I appear to be shown older, less relevant content going back to late 2000s to 2020 (could this be a form of censorship from a DNS-redirect or DNS cache poisoning?)
Many System Settings pages are modified with standard options missing (e.g. Power/Battery Preferences, Network Preferences etc.) compared to the content described in the MacOS software manuals. This leads me to believe that my device may have been MDM'ed some way.
Despite being logged in with Apple Account with FileVault enabled, the "Activation Lock Status" continues to be reported as "Disabled" in System Information.
Since doing the DFU restore at Apple, I have searched and come across references to a Mojo/Thor malware/virus that is believed to be transmitted through Thunderbolt adapters. It makes me wonder if the Apple Stores' Thunderbolt adapters may be a common vector?
From the EtreCheck report, it makes no sense that there are two additional ethernet adapters (en3/en4) configured as I am not connected except by WiFi (en0).
