Is there a feature in Cortex that allows us to monitor which endpoints use USB to transfer data?


L5 Sessionator

hi @RajeshPremSingh how about a XQL query to start off with the investigation?

dataset = xdr_data // Using the xdr dataset
| filter event_type=FILE and event_sub_type = ENUM.FILE_WRITE and action_file_size != null //filter out 0 byte files


From the results, can you identify out the device information and share some results (redacting any secrets)? 

The displayed results pertain to application data usage rather than USB data usage. I am specifically looking for an endpoint that is utilizing USB.Screenshot 2023-05-25 051421.png
