But people are taking this seriously because it represents quite an attack vector once things fall into place. The thing is we won&amp;#x27;t know when we&amp;#x27;ve reached that threshold until the first news stories about a widespread phishing scam using the technique emerge. It seems VoIP will be the first low-hanging fruit: https://arxiv.org/pdf/1609.09359.pdf&lt;/p&gt;&lt;p&gt;&lt;a href="https://hackerpaper.kaipfister.de/p/1609.09359/"&gt;Paper and discussion history&lt;/a&gt;.

So you better have a soundproof room for that purpose. Keep any electronics out of the room that might have a microphone. Like phones, laptops, or running mechanical hard drives [1].

See, e.g., Timing Analysis of Keystrokes and Timing Attacks on SSH (https://people.eecs.berkeley.edu/~daw/papers/ssh-use01.pdf), Don’t Skype &amp;amp; Type! Acoustic Eavesdropping in Voice-Over-IP (https://arxiv.org/pdf/1609.09359.pdf). Deciphering content from latencies in packetized speech is likely much more difficult, but I wouldn&amp;#x27;t put much stock in it being too difficult. Which is to say, if you&amp;#x27;re transferring high-value information assets over VoIP you should probably assume it&amp;#x27;s decipherable. That doesn&amp;#x27;t mean you should change what you&amp;#x27;re…&lt;/p&gt;&lt;p&gt;&lt;a href="https://hackerpaper.kaipfister.de/p/1609.09359/"&gt;Paper and discussion history&lt;/a&gt;.
