There is information that leaks through the power line as well, and the author of this paper also has a paper on how to exfiltrate through the power line at a much slower rate https://arxiv.org/abs/1804.04014

> I won't be surprised if even the power connection becomes a future (unintended) means of data transmission. That's already a thing. From the same author as the TFA, PowerHammer [1] exfiltrates data using current flow fluctuations. There's also Powermitter [2] (from some researchers at Wuhan University), which is exfiltration via power supply EMF leakage.

Powerline communications usually needs dedicated Ethernet (or what have you) <-> power line converter... I think they meant something more like powerhammer [1] which works by controlling processor workload, causing the power draw of the system to throttle up and down in such a way that it becomes a useful exfiltration channel (assuming your adversary can tap into a distribution board and measure power usage).
