Just how easy is it to intercept your cellphone signals, be it texting or calling? Julian Oliver showed off the simplicity of it by adding a GSM base station to the internals of an HP printer and thanks to its proximity to your phone it easily overpowers the signal sent by your providers cell tower. It can text and call you or intercept anything sent from your phone once your device connects, showing just how easily unencrypted cell signals can be monitored. This particular project is for an art show with warnings displayed for attendees, as this is to highlight the simplicity of eavesdropping as opposed to the nefarious purposes it could easily server. Drop by Ars Technica for more detail, including the code he used.
"Earlier this week, the Berlin-based hacker-artist unveiled the result: An entirely boring-looking Hewlett Packard printer that also secretly functions as a rogue GSM cell base station, tricking your phone into connecting to it rather than your phone carrier’s tower, effectively intercepting your calls and text messages."
