First I admit this is tangentially a sys admin issue. But today after a lot of iPhone users updated their work phones to the latest iOS teams seems to making itself the default app for FaceTime and cell calls, which if they aren't lisc for teams voip just shits the bed.

We've tested on a phone going into several default locations to change the defaults back to FaceTime/cell but even after these changes when clicking on a contact and selecting FaceTime some contacts still use teams.

Uninstalling teams seems to resolve the issue, but isn't a functional option.

Anyone else dealing with this, or resolved it as scale?

I can't find anything running on these machines, it was short burst activity, only scanned a total of 16 ports happened from two separate machines on the same network.

Was thinking some sort of worm, but the range seems off.

Defender detected nothing, nothing coming up on several different scans (endpoint and specific malware)

Anyone run into anything like this?
