Disclaimer, while I work for Code42 software, these were built for internal use and are not part of the product. 

Hey, I wanted to share some extension attribute scripts I created for Code42 Incydr (Professional, Enterprise, Horizon, and Gov F2. - or more generically the Code42-AAT.app). A shoutout to @MLBZ521, as I used some logic from their scripts. A bit more specifically. there is logic built into these for local logging if you need that.  I hope others can find these useful. 

 

First is a script to validate that the Configuration Profile that is required to run the app is in place. This is a great pre-deployment check to make sure the application will run properly after install. 

 

#!/bin/bash
# set -x

Second is a script to check that the System Extension is in a good state.

 

#!/bin/bash
# set -x

##############################################################################################################
# Script Name:  incydr_sys-ext_check.sh
# By:  Perrin Bishop-Wright / Created:  8/19/2022
# Version:  1.0.0 / Updated:  8/19/2022 / By:  PBW
#
# Description:  This script checks to see if the macOS endpoint has the proper System Extension status for Code42 Incydr
#				applicatoin (Code42-AAT.app) - Professional, Enterprise, Horizon, and Gov F2. 
##############################################################################################################


## If capturing local logs specify the path below. If not change "locally_log" to false. 
locally_log="true"
local_logs="/opt/ManagedFrameworks/EA_History.log"

write_to_log() {

	# Arguments
	# $1 = (str) Message that will be written to a log file

	local message="${1}"

	if [[ "${locally_log}" == "true" ]]; then

		if [[ ! -e "${local_logs}" ]]; then

			bin/mkdir -p "$( /usr/bin/dirname "${local_logs}" )"
			/usr/bin/touch "${local_logs}"

		fi

		time_stamp=$( /bin/date +%Y-%m-%d\ %H:%M:%S )
		echo "${time_stamp}:  ${message}" >> "${local_logs}"

	fi

}

report_result() {

	# Arguments
	# $1 = (str) Message that will be written to a log file

	local message="${1}"

	## If capturing local logs specify the message. If not comment out the line below. 
	write_to_log "C42 SysExt Status:  ${message}"
	## JAMF Extension Attribute direction. If not comment out the line below. 
	echo "<result>${message}</result>"
	exit 0

}

sys_ext_ctl=$(systemextensionsctl list | grep 9YV9435DHD | awk -F'	' {'print $6'})

echo "$sys_ext_ctl"


if [[ "$sys_ext_ctl" == "[activated enabled]" ]]; then
	report_result "[activated enabled]"
elif [[ "$sys_ext_ctl" == "[terminated waiting to uninstall on reboot]" ]]; then
	report_result "[terminated waiting to uninstall on reboot]"; 
#elif [[ "$sys_ext_ctl" == "$sys_ext_ctl" ]]; then
#	report_result "$sys_ext_ctl";
elif [[ "$sys_ext_ctl" = "" ]]; then	
	report_result "No System Extension";

fi

 

 

 

Third is to grab the date of the last time the application sent data to the Incydr authority. 

 

#!/bin/bash
# set -x

## If capturing local logs specify the path below. If not change "locally_log" to false.

write_to_log() {

	# Arguments
	# $1 = (str) Message that will be written to a log file

	local message="${1}"

	if [[ "${locally_log}" == "true" ]]; then

		if [[ ! -e "${local_logs}" ]]; then

			bin/mkdir -p "$( /usr/bin/dirname "${local_logs}" )"
			/usr/bin/touch "${local_logs}"

		fi

		time_stamp=$( /bin/date +%Y-%m-%d\ %H:%M:%S )
		echo "${time_stamp}:  ${message}" >> "${local_logs}"

	fi

}

report_result() {

	# Arguments
	# $1 = (str) Message that will be written to a log file

	local message="${1}"

	## If capturing local logs specify the message. If not comment out the line below. 
	write_to_log "C42 Last Transmit:  ${message}"
	## JAMF Extension Attribute direction. If not comment out the line below. 
	echo "<result>${message}</result>"
	exit 0

}

last_transmit=$(grep "message_tran | Transmitted" /Library/Application\ Support/Code42-AAT/Data/logs/code42-aat.log |tail -1 | awk '{print $1}')

report_result "$last_transmit"

This is great! Thank you!

Small edits:

In your second script:

bin/mkdir -p "$( /usr/bin/dirname "${local_logs}" )"

should be:

/bin/mkdir -p "$( /usr/bin/dirname "${local_logs}" )"

 

And for the last script. Code42 AAT moved their logs:

last_transmit=$(grep "message_tran | Transmitted" /Library/Application\ Support/Code42-AAT/Data/logs/code42-aat.log |tail -1 | awk '{print $1}')

to

last_transmit=$(grep "message_tran | Transmitted" /Library/Application\ Support/Code42-AAT/logs/code42-aat.log |tail -1 | awk '{print $1}')
