Another downside:
Recently the Federal Government sent out a malware to certain persona of interest. That malware played a higher pitch sound than can be heard by the human ear. They were able to track that person and identify them because they heard the sound on the computer's microphone. TOR or VPN can stop this.
- koolba 9y ago> That malware played a higher pitch sound than can be heard by the human ear. That should be "... can not be heard ..." right? Also, do you have a link with more details.
- wccrawford 9y agoNo, it's right as-is.
- Tushon 9y ago"a higher sound than can be heard" or "played a sound, which cannot be heard due to its pitch" would both work, but your interpretation isn't correct.
- pubg 9y agoWithout a source to corroborate, the tinfoil hat factor is extremely high with this one
- drawnwren 9y agoI slightly agree. However, these days it seems more and more that "thing elite spy agency does to track terrorist" is on about a 6 months to 1 year lead on "thing startup does to target ads."
- jamiek88 9y agoWouldn’t even surprise me if it was the other way around either. Some of the brightest minds of this generation are working on ad tech. Sadly.
- im3w1l 9y agoAbility and motive... Are they able to do this? Yes, for sure. Are they willing to this? For terrorists or maffia bosses, no doubt. For smaller fish? Maybe they can't be bothered. Or maybe they can.
- Florin_Andrei 9y agoOnce it's productized, it's probably easy to reuse.
- im3w1l 9y agoTechnically, but maybe not bureaucratically.

- gozur88 9y agoI'm surprised a computer speaker has the frequency response to play an inaudible tone.
- jm547ster 9y agoMost wouldn’t, I’d imagine OP is referring to a mobile device, look at Androids dev docs they recommend sticking to 44.1khz, which we know does fail into the range of human hearing with its 22khz reproduction, albeit fewer people. I’d suspect the person being spied on would become suspicious upon many children they encounter and even more dogs fleeing from their direction.
- isostatic 9y agoTested my kids - they could hear an alleged 21khz tone out of laptop speakers. The actual level of the tone doesn't matter - it was above my level of hearing. Wasn't a double blind, but they told me when it started and stopped based on a bash script with random intervals.
- BenjiWiebe 9y agoI'm 20 but I can still hear 20 khz, albeit not very well.
- isostatic 9y agoI could when I was 20, did a proper hearing test when I joined my company. 15.625khz was very noticeable - I scoffed at the old timers who couldn't hear it. I can no longer hear it. Still I can hear 1khz, so that's what's important.
- schoen 9y ago> TOR or VPN can stop this. You're saying that the persons of interest in this case were identified and targeted only based on an IP address and not based on some other aspect of their online activity?
- thinkloop 9y agoIf they were able to gain access to a person's microphone doesn't that mean they are already compromised?
- nathancahill 9y agoWasn't this how they caught the Silk Road guy? Ross Ulbricht? They played a loud noise from his computer in a public area, as I recall.
- jstanley 9y agoDo you have a source for that? I've never heard it before.
- nathancahill 9y agoNevermind, they chatted with him, but that was to ensure that he was logged in to SR before grabbing his laptop in an unencrypted state, not to identify him: https://www.wired.co/2015/01/silk-road-trial-undercover-dhs-fbi-trap-ross-ulbricht/ https://www.wired.co/2015/01/silk-road-trial-undercover-dhs-...
- marme 9y agothat is not how they caught him. They used a correlation attack. He was stupid and posted something using his personal email on stackoverflow about setting up tor website and processing bitcoin transactions. He then used a linked account to advertise silk road a few times. This made him a prime suspect. They followed him for weeks and watched that every time dread pirate roberts logged in and posted on silk road he was sitting in a cafe or library on his computer connected to a vpn. This was enough for them to get a search warrant and they found all the other evidence they needed to convict him on his laptop
