so let me start again. I want to connect a probe receptor either on the power outlet , on the common wall, with my neibourhood, either on the phone line outside on the street

Data Exfiltration from air gapped systems using power line communication

Proof-of-concept

To prove this attack actually works a small proof-of-concept implementation was written. For this POC BPSK modulation is used with a configurable carrier frequency and baud rate. All tools have been developed and tested on Linux.

The tools are available for download on Github: https://github.com/dimhoff/powercom.
