+    Video interfaces such as monitors emit electromagnetic waves. The attack commonly known as TEMPEST (or Van Eck Phreaking) consists in receiving this signal and inferring the image being displayed on the monitor; that is to say, pointing an antenna to a PC and spying the monitor. This inferred image tends to be noisy, but it can be enhanced by neural network such as KAIR to get readable text if you train it on images of e.g. webpages and PDFs (because usually documents are often the sought target of attacker). It's within realm of off-the-shelf SDRs.
