"O365 Suite EX" and "Office365 Shell WCSS-Client" Compromised
Hi,
I noticed the following Sign-in events originating from Nigeria, which is not the user location.
Seems like something is compromised.
Can I know what is the "O365 Suite UX" and "Office365 Shell WCSS-Client" about?
Thanks.
Unless the user connected via some sort of VPN solution, I'd wager his account has been compromised. Those events correspond to browser logins to the O365 portal/landing page.

Is there anyway to trace or run audit for whatever action or activities that has been run by that IP address? Thanks.
Not directly, but you can export the Unified audit log events and filter them against this IP. If you are using Cloud App Security, you can do it directly in the UI there.
Not all events generate IP address information though.

- waseemCopper Contributor“Office 365 Shell WCSS-Client is the browser code that runs whenever a user navigates to (most) Office365 applications in the browser. The shell, also known as the suite header, is shared code that loads as part of almost all Office365 workloads, including SharePoint, OneDrive, Outlook, Yammer, and many more.
