Attached images show the pop-up that is going around our network this morning. Unlike before where it would list the program Cortex blocks there is nothing there and is pointing at Microsoft for the cause.
Is this a false positive? A windows service is triggering Cortex to block the behavioral threat?

We are seeing Cortex Behavioral Threat High Blocks related to Microsoft. Pretty much all end points. smss.exe .. a MSFT signed file is identified. Unclear what is the precise cause.

Hi,
We're seeing the same here as well. End users are shown no application name, but digging through the incidents in the console shows that it's killing of Smss.exe, which is the System Center Configuration Manager agent.
All endpoints generating alerts are running 7.7.0.60725 here.
Looking through the timeline there seems to be no evidence of foul play.
