It's not an attack. It's just a backdoor that avoids transmission over the network. This allows airgapped computers and those with close network traffic monitoring to still be monitored without giving it away, "the radio frequency hardware must be physically inserted by a spy, a manufacturer or an unwitting user." It's just another antenna that the target would be unlikely to look for a transmission from.... until now I guess.
That's Ok, but you might agree, that since last year, the topic is highly political. I also don't think, that you could simply dissect discussion lines ...
