helps generate an XQL to notify when a USB is connected

L1 Bithead

I am trying to use Cortex XDR so that when a user connects a USB storage device I receive a notification by email.


so far I have used this XQL:

preset = device_control
| filter event_sub_type = ENUM.DEVICE_PLUG



which tells me when any USB device is connected to the endpoints, I added this as a BIOC rule so that when the condition is met it generates an alert.


and based on the BIOC the alert is generated, which I use as a basis for an automatic email sending rule. This works fine, and I get email notifications when a USB device is connected.


The issue is that it does not make a distinction between storage devices and other devices such as mice, headphones, Ethernet adapters, printers. Everything that connects via USB generates a notification.


How can I change the XQL so that it only shows me the USB storage devices or external drives that are connected but not others such as printers or headphones?

You can try filtering by drive_type. I believe drive_type = 2 is removable media.
