A small article about setting up the Proxmark3 for the first time.

The first thing we have to do, is shutting off a copuple of things before we can flash the PM3. We have to do this, because it is seen as a modem, and we reeeally don't want ModemManager to cuase trouble when we flash the firmware for first use. If it does, we would have a very fancy little paperweight, albeit a very expensive one, so let's not take any risks :)

Here I use a Kali machine, because that's what I got. It should be the same ofr any other kind of Linux based machine.

systemctl disable ModemManager

Now, we need to edit a couple of rules for modemmanager service.

systemctl edit ModemManager.service

Now we add this to the service file, and save the file as /etc/systemd/system/ModemManager.service.d/override.conf

[Service]
Environment="MM_FILTER_RULE_TTY_ACM_INTERFACE=0"

Restart the system with

halt -r now

Now, let's check that the override rule is applied before we do anything else.

mmcli -G DEBUG
journalctl -f|grep "ModemManager.*\[filter\]"

Now, try to plug in the PM3, and let's see what happens. If you get an output like the one below, it's bad. Something is not right, so so go back, and check everything again.

ModemManager[xxxxx]: <debug> [filter] (tty/ttyACM0): port allowed: cdc-acm interface reported AT-capable

The output below, is the "safe-to-continue" output. If you get this response from the check, you're all set.

ModemManager[xxxxx]: <debug> [filter] (tty/ttyACM0) port filtered: forbidden

So, if you're good to go. Let's move on, and install some dependencies we'll need.

apt-get install p7zip git build-essential libreadline5 libreadline-dev libusb-0.1-4 libusb-dev libqt4-dev perl pkg-config wget libncurses5-dev gcc-arm-none-eabi libpcsclite-dev pcscd

The next thing we'll need, is getting the client libraries fro PM3 from git.

git clone https://github.com/RfidResearchGroup/proxmark3.git

The next thing we'll need, is moving that folder, to somewhere we know it is. Mine is in /opt/proxmark3

So jump to where you copied the folder, and let's build the software.

make clean && make all

If the compiling went without errors, we're ready for the next step, the flashing itself. Hold down the button on the PM3, around four to six seconds, until it starts blinking, and then release the button.

In your proxmark3 folder, there should be a script called flash-bootrom.sh, run it with

./flash-bootrom.sh

If that finished ok, flash the rest with

./flash-all.sh

That should be it.

See if you can find the PM3. For that, you can use dmesg, and find the PM3 in the output, to see what terminal it's listening on. When you have that, connect to it using

./proxmark3 /dev/ttyACMx

If the client connected, you should be greeted with something like this

root@xeon:/opt/proxmark3# ./proxmark3.sh
Waiting for Proxmark to appear...
