SJM Merlin at Home

Jump to navigationJump to search

"Although the information we release has been verified and shown to work to the best our knowledge, we cant be held accountable for bricked devices or roots gone wrong."


This page will be dedicated to a general overview, descriptions, and information related to the St. Jude Medical Merlin@home Transmitter Model EX1150.


The Merlin@home Transmitter is intended to pair with an Implantable Cardiac Defibrillator (ICD) or Pacemaker and upload the data to the patient care network for review by a physician.



A Login Console is presented on UART (3.3v) at 115200 baud. The pinout for UART can be found below.


This device boots with the BLOB bootloader ( to a version of Montavista Linux ( with a restricted root login. It is possible to init hijack by interrupting the bootloader.

Taking Things Further

Lets look at some of these custom hotplug scripts. /etc/hotplug/usb/sjmusb looks like a good start.

#  Script to mount valid sjm pendrive(s) via hotplug. Hotplug will invoke 
#  this script only if the attached USB device is a mass-storage device.
#  hotplug does this by looking at the device class of the attached usb device
#  See /etc/hotplug/usb.usermap. The device class for mass storage devices
#  is  ______
#  In a nutshell, the script looks in /proc/scsi/usb-storage* directory to
#  find the scsi ID of the attached USB storage device. It then goes on to
#  find the device node corresponding to this scsi ID.
# version 1.1 - Added USB signature check functionality 
# For the new cellular adapters - viz mobidata and velocity, ignore the
# mass storage interface reported. Please see comments at the top of
# /etc/hotplug/usb/velocity for details.
#   - Ashok Iyer (16-Jun-2010)

# The functions in this script rely on "echo" to pass information to each
# other. If you need to modify this script, do not use "echo" for debugging.
# Instead use the feedback()/error_exit() functions below. These will log 
# information to a log file and do not interfere with information passing 
# between functions.


function check_sign {
    local node1=$1"1"
    feedback "Checking signature ... "
    feedback "node1 = $node1"
    dd if=$node1 of=/tmp/.sign bs=1 count=3 skip=501

# The remover script will be invoked when the device is removed. This is

# which is removed ( unlike umounting all attached USB flash drives )
feedback "REM = $REMOVER"
if [ -f $REMOVER ]; then

Lets look inside of /etc/


if [ $# -ne 1 ]; then
        echo "usage: ./ /mnt/pendrive"

# This script may be invoked by hotplug 
# Do not run the script if it is already running 
# updater or data export


if [ -f $mountpt/version.ini ]; then
	# call updater script
	echo "Launching updater script"
	if [ -f $mountpt/etc/init.d/ ]; then
		sh $mountpt/etc/init.d/ $mountpt > /tmp/debugUpdater.txt 2>&1
		umount /mnt/sjmpendrives/1
		umount /mnt/pendrive
		umount /mnt/sjmpendrives/1
		umount /mnt/pendrive
		exit 0
	# Call Data export script
	echo "Launching export data script"
	sh $script_path/ $mountpt
    umount /mnt/sjmpendrives/1
    umount /mnt/pendrive

It looks like their pendrive "signature" is fairly easy to get around.

Other Stuff to Look Into

I doubt this device has been updated to the latest firmware as I aquired it still wrapped in its packaging. As of January 2017 St. Jude Medical claims that a security patch has been applied to the newer firmware releases.

Below are some interesting things that were found.
