      A Ben Gurion University researcher showed how to generate WiFi signals (to exfiltrate data) on a computer that doesn't have WiFi. Impressive! https://arxiv.org/abs/2012.06884

      The author is the absolute king of exfiltration.

      Reminder: the CovertChannels stuff from Mordechai Guri is a paper mill with misleading titles. Stop giving them publicity. They aren't "Generating Covert Wi-Fi signals", they're encoding 10bps of data in 2.4GHz noise from a 2.4GHz RAM bus. That's not Wi-Fi.

      Sure thing, he's doing similar stuff again and again. But that tweet sounds like Reviewer 2 being angry for not having had that idea

      Back when I saw one of his papers I spent 5 minutes coming up with ideas without looking, and came up with about a dozen, most of which he'd already done... Also, this one is *literally* a rehash of his 2015 paper where he did the *exact same thing* with GSM.

      Except for the GSM one he was using a fully documented open platform GSM receiver and he *still* only got 1.5bps out of it blaming "not having full DSP access" or something, which is nonsense. He's just... not actually good at this at all.

      Like, if you read them, the papers are a bunch of fluff and then.... utterly unimpressive in every respect. There is almost no useful advancement of the art in there. It's all using the most boring techniques and modulations. Minimum effort to paper.
