Spies can eavesdrop by watching a lightweight bulb’s variations

This is a poor quality rewrite of the original wired article it cites: https://www.wired.com/story/lamphone-light-bulb-vibration-sp...

This article has gone through a machine translation and is full of grammatical errors.

Aha, that's what it is!

I was googling "constructing" (construction/building?) and "select up"/"decide up" to see if this was jargon.

> who plans to current their findings on the Black Hat safety convention in August

ahh... current = present. Geez..

I looked at another article by the same author. It began:

"One week left till Father’s Day 2020. Time to get severe a few reward for dad, when you haven’t already discovered one. I printed a present information a number of weeks again that focuses on client electronics."

Perhaps deliberately, to hide the fact that it's based on a stolen article (see comment above) or several scraped articles.

Reminds me of a 2014 work by MIT on extracting audio signals from vibrations of objects in a video [0] which I found was truly fascinating. I guess someone was paying attention to bring this to production mode out of the lab.
