PENTEST VIA CELLULAR NETWORK (III): SMS MESSAGES WITH HOLOGRAM PYTHON SDK
- Layout for this exercise (Smartphone and Raspberry Pi / SIM card / Modem):

- The goal of this exercise is to send/receive SMS messages between a Hologram modem (installed at a Raspberry Pi device) and a smartphone via the celullar network, using the Hologram Python SDK library.
- First of all, let's create an external data script where the device key and the phone number are stored:


- Now, importing libraries from the Hologram Python SDK, this Python script sends an SMS message and prints the successful result:


- Running SendTEST.py:

- In similar way, this Python script puts the modem into receiving mode and prints the message once it has been received:


- Running ReceiveTEST.py (in the image I have removed the sender phone number by privacy reasons):



- The smartphone screen displays the SMS messages exchanged with the modem:
