My business is using Office 365. Since yesterday on of our accounts has logged in through an application called 'Office Online Client- Loki'. 


Is this the malware LokiBot, or is it something that is normal for Office 365?


Thanks in advance 


Sorry if this is not the right forum

Loki is listed in the URL's for Delve, It could that.

On the site https://docs.microsoft.com/en-us/office365/enterprise/urls-and-ip-address-ranges, You can see the following URL's*.loki.delve.office.com, loki.delve.office.com, loki.delve-gcc.office.com, lpcres.delve.office.com.


However, the best option, if you are unsure, is to check which users have logged in. In AzureAD scroll down to the Sign-Ins and find which user attempted to connect with Loki. Click on the sign-in event and check where the user logged in from. If it was from a location/IP you know then you can run some AV/Malware tools over the user's workstations. If you don't know the IP/Location then I would start looking at resting the user's password, enabling MFA as well as scanning their PC.


If you have Microsoft Defender ATP, you can check cloud app security and seen of the user's PC has been infected as well.
