We are attempting to determine how many of our machines in our environment are using the LG Unifying RF receiver because of a vulnerability in them that allows for them to be hijacked. I believe an extension attribute would be the best way to determine if one of these are plugged into a device. Would that be the best way to do that? Is there a better way to determine which machines in our environment have that hardware plugged into it? Maybe an ioreg script?

Here is the information we are looking for: USB Receiver:

Product ID: 0xc52b Vendor ID: 0x046d (Logitech Inc.) Version: 12.03 Speed: Up to 12 Mb/s Manufacturer: Logitech Location ID: 0x14400000 / 1 Current Available (mA): 500 Current Required (mA): 98 Extra Operating Current (mA): 0

So I need to make an extension attribute that detects when something with that product ID and that version number are plugged into any Mac on our system.

Built out the following Extension Attribute: 

#!/bin/bash

#Determine Logitech adapter status
USB=$(system_profiler SPUSBDataType | grep '0xc52b')

if [[ "$USB" != "" ]]; then

    #Determine firmware version
    Version=$(system_profiler SPUSBDataType | grep 'Product|Version' | awk '/0xc52b/ { getline; print $2 }')

        if [[ "$Version" != "12.11" ]]; then

            echo "<result>Needs Update</result>"
        else
            echo "<result>Updated</result>"
        fi

else
    echo "<result>Not found</result>"
fi
